Do Teeth Whitening Strips Work?
You've seen the ads on TV and social media. They're the next big influencer trend, but do teeth whitening strips work?
If you want to learn more, please visit our website organic teeth whitening strips.
As with everything, it's all in the nuances, like how you use whitening strips and what your natural teeth are like.
This guide will teach you everything you need to know about teeth whitening in general so you can decide if whitening strips are the best way to go for you.
Why Whiten Your Teeth?
In a world full of instagram-influencers, teeth whitening products have become a booming industry.
So why do people spend their money on bleaching gels and whitening kits just to have a brighter smile?
For most people, the answer is because they're concerned about their appearance. It's not a selfish reason. Your feelings about your appearance are intricately tied to your self-esteem, and that's a mental health concern.
When you have discolored, brown or yellow teeth, it can cause you to be insecure about your smile. Whiter teeth and self-confidence are linked, so it's no wonder that people pay money for a whiter smile.
Reasons to Get a Tooth Whitening Treatment
There are multiple options for anyone trying to get white teeth. Whether you go the home teeth whitening route or head to a dentist's office for a professional teeth whitening can depend on the reason.
Common Occasions When You Might Want to Whiten Your Teeth
For discolored teeth from surface stains, most whitening strips do the job. However, using at home whitening strips can be dangerous if you don't follow the directions. Get a teeth whitening strip product that's approved by the American Dental Association, like Crest whitening strips. Never use a whitening agent without researching it first.
For special occasions, when you want to look your best, getting a dental cleaning and professional tooth bleaching procedures is the safest way to go. Head to your dental office at least a week before the special event. When you use a licensed medical professional, the whitening ingredients they have helps you avoid uneven whitening. With dental care, the dangers of using teeth whitening products are minimized.
To try to offset the long-term effects of aging or smoking, Crest Whitestrips and other at-home whitening products may not be the best solution. Crest Whitestrips work to remove the thin layer of stains on the surface. But what you have is a buildup of staining on your teeth. To remove stains that have been there a long time, you'll need to talk to your dentist.
Whatever the reason you've decided you want to try using whitening strips or another product, go for it! Just make sure you're on the right track to a healthy smile as you whiten your teeth.
How Do Whitening Products Work?
Are whitening strips the solution you need? Let's start by getting to know how any whitening product does its job.
When you apply whitening strips or a whitening gel, it seems like a simple process, and it is, to a degree. The products contain hydrogen peroxide or carbamide peroxide. Both of these bleaches work the same way.
The active ingredient, either hydrogen peroxide or carbamide peroxide, gets in the tooth enamel, down into the layer of dentin.
That's where the stains are, and the bleach breaks those stains up. This works to whiten teeth immediately by making the stains less obvious.
Are All Whitening Products the Same?
Just because Crest Whitestrips and other products have similar ingredients to a professional whitener does not make them the same.
Every whitener has peroxide as its basic ingredient, but that's where the similarities end.
The other ingredients aside from the active whitening ingredient make a difference, too. For instance, in a professional treatment, the dentist may add fluoride to help prevent the enamel from weakening.
This added ingredient also reduces gum irritation and sensitive teeth problems that come with a whitening strip, like Crest Whitestrips.
Warnings to Heed Before Using Whitening Strips or Products
However, some whitening strips have a bleaching agent called chlorine dioxide.
This ingredient does whiten teeth faster than hydrogen peroxide, but in white strips and other products, it can be dangerous.
Before you use any teeth whitener with chlorine dioxide in it, get advice from a dental clinic you trust.
It's always a good idea to talk to your dentist before starting a tooth whitening regimen. Not all whitening strips or products work on every type of discoloration.
Whitening products won't work on dental veneers, and they can worsen problems like tooth decay and gum disease.
Whitening Options
Getting brighter teeth can be accomplished in a few ways:
Stain removing toothpaste that scrubs away surface stains. Be sure to find an ADA-accepted product.
Over-the-counter bleaching products that have been ADA-approved. Note that these products have a lower concentration of bleach in them, so they don't work as effectively as a professional-grade product.
In-office bleaching in your dentist's chair. You'll have a protective gel or rubber shield added to protect your gums, and then the bleaching product is applied. This type of procedure usually only requires one or two visits for optimal whiteness.
At-home bleaching from the dentist's office. Your dentist will create a custom-made tray for you to use at home. You still get the benefit of professional-grade ingredients, but you use the whitener in the comfort of your own house. This is a slower-paced procedure. It's still popular for those who feel more comfortable doing their treatment at home.
Common Side Effects of Teeth Whitening
Whether you use teeth whitening strips or another whitening product, there are some side effects that can happen.
Following the directions on the package decreases your chance of dealing with these unwanted symptoms.
And getting whitening solutions from your dentist reduces the possibility of side effects even more.
What to Expect When You Whiten Your Teeth
If you use teeth whitening strips or another over-the-counter or non-professional-grade product, these are some of the things you might notice after your application:
An increase in tooth sensitivity as the whitener gel gets into the dentin. The gel irritates the tooth's nerve, which is why you feel tooth sensitivity there. This should be temporary. If it continues for more than a few days, see your dentist.
Gum tissue and other soft tissue damage if you use subpar products or overuse whiteners. Instead of continuing to try to whiten teeth with alternative methods, talk to your dentist about ways to avoid staining in the first place. Certain foods and beverages tend to stain your teeth. Brushing twice a day is good for your teeth and gums and reduces the chance of staining.
Damage to the enamel if your white strips don't have a pH-balancing ingredient in them. There's a reason we're taught to keep bleach out of our mouths at a young age. In small doses, like you find in whitening products, it's "safe." But if the product doesn't have balancing ingredients, you may end up with enamel damage.
If you've had dental work done recently, talk to your dentist before using any whitener. You may also have to find someone to provide medical advice if you have health conditions that could be affected.
Natural Whitening Options
If your medical or dental history makes teeth whitening strips or professional options a no-go, you still have options.
Avoiding those foods, drinks, and bad habits (like smoking, alcohol, and drugs) can mean your upper and lower teeth stay white.
But if you're ready to get them a little brighter, you can use toothpaste with sodium hydroxide or baking soda in it.
These products don't work to brighten your teeth quickly, but they're typically safe on your gums and enamel.
Ready for the Whitest Smile Safely?
When you are serious about getting a white, bright smile, the dentist is the best place to start. With professional whitening options, your natural teeth can become pearly white safely.
Some offices offer professional take-home whitening kits that are custom-fitted to your mouth.
You can also have an in-office treatment with professional-grade ingredients and special tools designed to optimize your enamel's colors quickly.

The 12 Best Teeth Whiteners to Tackle Tough Stains
Whitening toothpastes contain low levels of peroxide and are less effective than other whitening products. Toothpaste results are temporary. To determine the effectiveness of a toothpaste, check its relative dentin abrasion (RDA) on the manufacturer's website.
Whitening pens contain a peroxide gel, which is typically applied with a brush head . The peroxide available in pens is often lower than in a gel kit, and their lower duration makes them less effective than at-home treatments, but their effectiveness is sacrificed for their ease of use on the go.
LED-powered devices are another popular choice. They work by using the peroxide gel as a base and activating the gel. The LED works to speed up the gel's effects , accelerating the process and enhancing results through an oxidation process. LED devices also have their own set of negative side effects (such as causing tissue damage), so dentists warn that you should use caution if adding one to your dental routine.
Whitening gel comes into play in almost all whitening kits, typically acting as the activator in LED kits and whitening pens , as well as on their own, applied directly to teeth or in trays. Whitening gels are normally made with either hydrogen or carbamide peroxide.
It's worth noting that an ingredient making its way into whitening kits lately is PAP (or phthalimido-peroxy-caproic acid), which should be avoided . According to Edmond R. Hewlett, DDS, Professor at UCLA School of Dentistry, unlike hydrogen peroxide, PAP may lead to lingering sensitivity.
The most common ingredient in teeth whitening kits is peroxide, either hydrogen or carbamide . These ingredients work to remove stains both on the surface of teeth and on deeper layers. In addition to these ingredients, you'll also want to look for a few others that can help ease the after-effects of whitening, which can be painful for sensitive teeth. Dr. Velayo recommends also looking for potassium nitrate, fluoride, and/or xylitol because they can minimize sensitivity.
To find the best teeth whiteners, we tested over 50 products in our lab and are continually testing at home. We've narrowed down our list of top products by following expert guidance and ranking each option based on criteria such as convenience, comfort, effectiveness, and overall value . An orthodontist on our Medical Expert Board also reviewed this article for medical and scientific accuracy.
Teeth whiteners are an easy, convenient way to brighten your teeth a few shades, but they can also work under the enamel to remove built-up staining. If you&#;re looking for long-lasting results, Bianca Velayo, DMD of Green Valley Smiles Dentistry, recommends looking for peroxide-based products if you're hoping to whiten tooth enamel . You can opt for either carbamide peroxide or hydrogen peroxide as both will reverse internal and external stains on teeth , she notes. But Dr. Velayo adds that while a peroxide-based treatment is your best bet for a long-lasting treatment, how well the product works will come down to the concentration of the peroxide, how long you use it, and how it's applied.

Why We Like It
The Crest Whitening Emulsion with LED Light stands out as the best overall teeth whitening product due to its ease of use, effectiveness, and comfort. Its simple, straightforward process, coupled with the ability to carry on with normal activities during treatment, makes it highly convenient and user-friendly. With noticeable results and a gentle formula that minimizes sensitivity, it provides an unparalleled whitening experience.
The whitening process was remarkably straightforward, and it was so simple that we initially doubted if we were doing it correctly! All we had to do was apply the gel, carry on with our daily activities for 30 minutes, then use the LED device in our mouths for 3 minutes, and that was it. The entire process takes about 33 minutes and is completely painless. No charging is required for this product, which is convenient, and it comes in a box with a small plastic stand for the wand and whitening product.
The product's instructions allow for up to four uses per day, which is surprising considering potential sensitivity issues but we experienced no issues, a surprising plus given our lack of gum sensitivity. The results were noticeable, lightening our teeth by about two shades. This kit was more enjoyable compared to other products we tested. It's easy to apply, comfortable to wear, and discreet enough for use during activities like Zoom calls, making it worth the investment for quick, effective whitening.
It's Worth Noting
- This product is recommended to be applied four times a day, which could be inconvenient if you&#;re looking for a lower-maintenance product.
Product Details:
- Type: LED light
- Recommended frequency of use: Four times a day
- Recommended duration of use: 33 minutes
- Active ingredients: Hydrogen peroxide

Why We Like It
The Laser Glow Purple Toothpaste stands out as the best purple whitening paste due to its unique formula that combines ease of use, gentle whitening effects, and a pleasant taste, making it a standout choice for those seeking a mild and convenient teeth whitening solution.
It applied easily, although initially more liquidy than regular toothpaste. The first few seconds of brushing left a temporary purple hue on our teeth, but this quickly dissipated. The toothpaste, with its gel-like consistency, was easy to use and didn&#;t foam, allowing for thorough brushing without causing sensitivity. It had a minty, pleasant taste after an initial medicinal flavor. While we didn&#;t notice dramatic, immediate effects, our teeth appeared slightly whiter over time.
It offered a mild whitening effect and was a simple addition to our morning routine. While not a robust whitening solution, we&#;d recommend it for those interested in a gentle, convenient product.
It's Worth Noting
- It may not provide as strong or noticeable whitening results as some users might expect or need, especially when compared to more intensive whitening treatments.
Product Details:
- Type: Toothpaste
- Recommended frequency of use: Daily
- Recommended duration of use: 2 minutes
- Active ingredients: Hydrated silica, xylitol

Why We Like It
Auraglow&#;s Deluxe Teeth Whitening Kit uses a handheld LED device to whiten teeth in 30-minute sessions over the course of one week. The device claims to whiten up to 10 shades in that amount of time, which we found to be true.
But, while we found our teeth were noticeably whiter after testing, the device itself did leave us wanting more. The tray is quite large, especially for smaller mouths. However, in our opinion, the slight discomfort from the large tray isn't enough to take away from the satisfaction we got from the results. And given how much we know professional whitening costs, we would absolutely say this is worth the price for a brighter smile.
It's Worth Noting
- This product needs to be recharged at least once a week with regular use, yet it doesn't give a low-battery warning.
Product Details:
- Type: Gel
- Recommended frequency of use: Daily for 1 week
- Recommended duration of use: 30 minutes
- Active ingredients: 35% carbamide peroxide

Our Ratings
Why We Like It
The Lumineux Bright Pen provides a gentle yet effective whitening solution that avoids the common issue of increased sensitivity or irritation, making it an ideal choice for those who want a brighter smile without discomfort.
Peroxide&#;either hydrogen or carbamide&#;is the active ingredient in most whitening products, but it can lead to tooth sensitivity. Lumineux, a fan-favorite whitening company, makes all its products without peroxide. Instead, they use a combination of essential oils to provide results&#;without any chemical taste you get from most whitening products.
Using the pen was straightforward: just twist, apply, and go. It was so easy that we could do it without a mirror. The pen's precise brush allowed for effortless application, reaching every part of our teeth without any mess. We had to wait 30 minutes after application before eating or drinking. Within two weeks, we noticed our teeth becoming a shade lighter, enhancing our confidence in our smile. We didn&#;t experience any sensitivity or irritation, a welcome change from our past experiences with teeth-whitening products. The pack included two pens, offering excellent value for a single purchase or a $10 discount with a subscription.
It's Worth Noting
- The results may not be as dramatic as other pens that use peroxide.
Product Details:
- Type: Pen
- Recommended frequency of use: 7 days or whenever needed
- Recommended duration of use: 1 minute
- Active ingredients: Coconut oil

Best Trays

Our Ratings
Why We Like It
Opalascence Go Prefilled Trays wins our pick for best teeth whitening trays. A whitening tray can offer a happy medium between white strips and an LED device, typically with a more comfortable and sometimes more effective output. The Opalescence Go Prefilled Trays use a 15% hydrogen peroxide treatment, which is higher than some of the other options on our list, meaning you&#;ll get faster results.
We noticed almost immediate results after one use, although the higher dose causes some discomfort and sensitivity. We tried the higher formulation, but Opalescence also makes its trays in a 10% hydrogen peroxide formulation.
Opalescence is also a favorite brand of dentists, particularly Dr. Velayo. &#;More clinical studies, articles, and reviews have been published on Opalescence whitening than any other professional whitening brand. It's part of the reason why it's so highly trusted,&#; she says.
It's Worth Noting
- These may not work well for people with tooth or gum sensitivity.
Product Details:
- Type: Gel trays
- Recommended frequency of use: 5&#;10 days
- Recommended duration of use: 15-20 minutes
- Active ingredients: 15% hydrogen peroxide; also available in 10%

Best for Sensitive Teeth
Crest 3D Sensitive Teeth Whitening Kit

$32 at Target
Our Ratings
Why We Like It
Tooth sensitivity is one of the biggest concerns for people looking to get whiter teeth. Some products are designed for sensitive teeth&#;like the Crest 3D Sensitive Whitestrips. The difference is a lower peroxide level; the sensitive strips contain 5.25% hydrogen peroxide compared to Crest&#;s standard 6.5%.
We were surprised by how gentle this product was on our very sensitive teeth and gums. We also noticed a difference in the color of our teeth right away while using the strips. The Crest Whitestrips for Sensitive Teeth work like the other strips in Crest&#;s lineup: just wear them once a day for 30 minutes, and you should see full results in about two weeks&#;all without tooth pain. Plus, these strips use Crest&#;s AdvancedSeal tech for a non-slip grip on teeth during whitening.
It's Worth Noting
- They may not brighten your teeth as much as other Crest Whitestrips because of their lower peroxide percentage.
Product Details:
- Type: Strips
- Recommended frequency of use: Once daily for 14 days
- Recommended duration of use: 30 minutes
- Active ingredients: 5.25% hydrogen peroxide

Best Strips
Lumineux teeth whitening strips

$23 at Amazon
Why We Like It
While using peroxide to bleach your teeth isn't harmful, it should be limited because it can soften your enamel over time, says Dr. Hovanisyan. If you&#;re worried about peroxide use, Lumineux Teeth Whitening Strips is peroxide-free, using essential oils instead of more standard chemicals to whiten teeth. Its ingredient list includes lemon peel oil, coconut oil, sage oil, and Dead Sea salt.
If you&#;re wondering how well all-natural whitening solutions stand up to chemical whitening, the answer might be surprising. A study of chemical teeth whitening and all-natural teeth whitening products found that while chemical whitening provided more drastic results, all-natural products weren&#;t far behind&#;plus they left teeth with fewer surface issues after use.
We found these strips comfortable and easy to use, allowing us to carry on with our daily activities, including conversations, during the 30-minute treatment. The strips, which lack an unpleasant taste and instead offer a slightly refreshing flavor, showed effectiveness after two to three applications, gradually whitening our teeth by approximately two shades. We also found that the strips were easy to apply and stayed on our teeth even while talking, though they only cover the front 6-8 teeth on each row. For 21 treatments, we consider them a great option, especially given their effectiveness and suitability for sensitive teeth and gums.
It's Worth Noting
- We advise caution in storing them in warm conditions, as we encountered a strip becoming gooey and tearing in high temperatures.
Product Details:
- Type: Strips
- Recommended frequency of use: 7 days, then 1&#;2 times per week for maintenance
- Recommended duration of use: 30 minutes
- Active ingredients: Coconut oil

Our Ratings
Why We Like It
Like some of the other products on our list, the iSmile Teeth Whitening Kit uses gel in combination with an LED device, but this device has a clean and easy application, which is rarely guaranteed with gel products. That&#;s why it&#;s our tested pick for the best teeth-whitening gel. It's convenient how you can apply the solution onto the mechanism before putting it in your mouth. This allows it to be less messy and for the solution to be evenly applied when you bite down.
It&#;s also fairly quick and effective, requiring only 10-minute treatments over the course of a week, which brought us up five shades in lightness. We think it may have been more effective than previous whitening treatments we&#;ve done in the past at the dentist&#;s office.
It's Worth Noting
- The only drawback is the slight discomfort. No teeth whitening product that has to sit in your mouth for an extended period of time will ever be extremely comfortable.
Product Details:
- Type: LED device
- Recommended frequency of use: Once daily for 7 days
- Recommended duration of use: 10 minutes

Best Budget LED
Cali White White Teeth Whitening Kit

Our Ratings
Why We Like It
The Cali White Teeth Whitening Kit is a quick and easy teeth whitening kit. The LED process is a 10-minute three-step process, and then you&#;re done and ready to take on the world with a lighter and brighter smile. The sessions are quicker than LED options (10 minutes versus 30), and this is a more affordable option as well, which gives this product a lot of value.
The process required us to squeeze out the gel onto the tray, put the tray into our mouths, and turn on the LED light. That&#;s it! At the end of the lighting session, the LED light automatically turns off, which is good if you lose track of time or forget to use a timer.
By the end of initially testing this product, our teeth were one to two shades lighter. We didn't experience any discomfort beyond the mint-tasting paste, causing our gums to tingle throughout use. However, though it comes with a travel case for the guard, we do wish it included a travel case for the LED light too.
It's Worth Noting
- The tray is a little big, so we had a little bit of trouble trying to breathe through our nose during use, which could be cumbersome for smaller mouths.
Product Details:
- Type: LED device
- Recommended frequency of use: Once daily for 7-10 days
- Recommended duration of use: 10-30 minutes

Our Ratings
Why We Like It
We found the Colgate ComfortFit LED Teeth Whitening Kit refreshingly uncomplicated to use, with no app required. This kit is conveniently powered by a cell outlet, making it easy to use on the go. We simply plugged it into our cell , put the tray in our mouth, and continued with our routine. The built-in auto-timer for 10 minutes, with beeps to indicate halfway and completion, made the process hassle-free and effortless.
We often used it during our nighttime skincare routine and would forget it was even there, thanks to its comfortable fit. The tray, being flexible and adjustable, caused no irritation or discomfort, and we felt no sensations while using it. After a couple of uses, we noticed our teeth looked brighter, though not necessarily a full shade lighter. Compared to white strips, which can leave the mouth feeling unpleasant and require constant swallowing of gel, this kit was barely noticeable and met our expectations for ease and comfort.
It's Worth Nothing
- However, we would have appreciated extra whitening pens, as we quickly used up the first one.
Product Details:
- Type: LED device
- Recommended frequency of use: Once a day for 3 months (but results are noticeable after 3 days)
- Recommended duration of use: 10 minutes
- Active ingredients: Hydrogen peroxide

Why We Like It
The PurelyWHITE DELUXE Teeth Whitening kit is our pick for best teeth whitening kit for stains. It&#;s an LED-powered device that&#;s great at targeting ten years' worth of stains and spots on the teeth with minimal sensitivity.
There&#;s no app with this teeth whitening kit, and the process is simple and reminiscent of many other whitening kits on the market. The process itself was simple and quick, taking about 12 minutes per session. We immediately saw a difference in certain spots of our teeth after using the kit. However, the whiteness did seem to fade over time.
While this device doesn&#;t need to charge, we did experience some issues with the batteries. Turning it on and off can be a struggle, and in order for it to operate properly at times we had to completely remove the batteries. Despite these challenges, we still think the product is worth its price tag, as it does work.
It's Worth Noting
- The timer stopped working after our fifth use, so if you need a teeth whitening kit with a timer this may not be the best option for you.

- Type: LED whitening device
- Recommended frequency of use: Once per day

Why We Like It
The Boka Teeth Whitening Strips is our top choice for teeth whitening without peroxide, offering a safer, non-toxic alternative for achieving a brighter smile. Their innovative formula uses Phthalimido-Peroxy-Caproic Acid & N-HA (Nano Hydroxyapatite) for effective results with minimal sensitivity. We noticed a visible improvement in our teeth&#;s whiteness after just four applications. We found these strips were comfortable to wear, but it took a moment to figure out the correct placement. The entire process fit seamlessly into our routine, taking only 33 minutes, including application and cleaning. By the fifth use, we experienced minor teeth sensitivity but it was manageable. With a pleasant flavor and peroxide-free formula, these strips offered great effectiveness for the price.
