We chose Hismile as the best teeth whitening kit because the product causes zero sensitivity. This is thanks to phthalimido peroxy caproic acid (PAP). PAP is a new non-hydrogen peroxide bleaching agent shown to be an effective tooth whitener with minimal to no side effects (like sensitivity).

Dr. Aggarwal and Dr. Sidhu agree that PAP is a promising whitening agent. It’s a safe and effective alternative to peroxide that doesn’t release free radicals during whitening. The whitening kit also includes the world’s first at-home VIO405 light, which has 32 LEDs as opposed to the traditional five in most devices.

In addition to PAP, Hismile uses remineralizing ingredients to boost enamel health and provide protection:

• Nano Hydroxyapatite (nHAp) rebuilds the protective layer of teeth and replaces lost minerals
• Potassium citrate helps relieve pre-existing sensitivity

What Our Testers Say

One of our testers has extremely sensitive teeth. He’s tested over 20 whitening products, most of which caused some sensitivity. Hismile’s kit doesn’t, so he keeps going back to it. The kit also feels premium, effectively whitens teeth, and doesn’t require 30+ minutes of use.

Note: Some dentists believe PAP causes more sensitivity than peroxide. We discovered the opposite during our testing. Results may vary.

What’s Included:

• 1 VIO405 device and charger cable
• 1 VIO405 travel case
• 6 VIO405 whitening refills
• 1 PAP+ primer
• Instructions on packaging

Pro Tip

Add the PAP+ Solution to the front of the mouthpiece’s surface so it touches the front of your teeth, not the bottom.

We recommend Auraglow’s LED kit for a fast, affordable, and effective whitening experience. Although the whitening gel has a higher peroxide content (35% carbamide peroxide), Auraglow’s products are designed with sensitivity in mind.

Carbamide peroxide is one of the most commonly used bleaching agents. It breaks down slower than hydrogen peroxide and may cause less sensitivity. One study found that it reduced tooth sensitivity risk from 67% to 89% compared to hydrogen peroxide.

What Our Testers Say

One of our testers used Auraglow’s LED whitening kit three times (three days in a row). Her teeth were noticeably lighter after the first use and about two shades lighter after the third use.

After the second use, the kit caused minor sensitivity, but these effects were temporary. She also likes that the gel contains xylitol, which has known dental health benefits.

What’s Included:

• 1 hands-free LED mouthpiece
• 1 carrying case and charger
• 2 vials of teeth whitening gel
• Instruction manual

3. Crest 3D Sensitive Whitestrips

Best for Safe Teeth Whitening

Ease of use:

Shop 3D Sensitive Whitestrips on Crest

Crest 3D Whitestrips for Sensitive Teeth is our number one choice for safe teeth whitening. This is because the product has the American Dental Association (ADA) Seal of Acceptance.

Any products with this seal have been thoroughly tested and studied. They must be proven safe and effective for at-home use via the ADA Council on Scientific Affairs regulations.

Crest recommends completing the full treatment course (14 days straight) every 6 months. Depending on your desired results and reaction to the product, you can reduce this time. We recommend checking progress after 3 days of consistent use.

What Our Testers Say

Our testers found that Crest Whitestrips (Sensitive) caused minimal to no sensitivity. Results were noticeable after just two to four uses.

The strips also have great adhesion, making them easy to put on and remove. And the compact packaging makes them perfect for on-the-go whitening during vacation.

What’s Included:

• 14 treatments total — 28 teeth whitening strips (14 upper; 14 lower)
• Instruction manual

We chose Snow’s At Home Teeth Whitening Kit as the ‘best value for your money’ because each kit contains about 75 treatments. Other kits on the market come with 14 treatments or less, so Snow stands out in this category.

Snow’s whitening gel also includes a mixture of hydrogen and carbamide peroxide. These active ingredients are effective and safe whitening agents.^3,4

What Our Testers Say

Snow offers original and extra-strength whitening serums. Our testers tried both. The extra-strength serum (more peroxide) generally caused more sensitivity. Because of this, we recommend using the original serum with less peroxide. Both were effective tooth whiteners.

What’s Included:

• 3 teeth whitening wands (75+ treatments)
• 1 extra-strength whitening wand
• 1 LED mouthpiece
• Shade guide
• Instruction manual

Spotlight Oral Care was founded by two dentists, Dr. Lisa and Dr. Vanessa. We recommend these as the best strips because they provide the most noticeable results after just one use, which is rare for whitening strips.

These professional-grade whitening strips are made with the active ingredient hydrogen peroxide. Using the strips daily for one hour (for 14 consecutive days) is recommended to achieve a whiter, brighter smile.

What Our Testers Say

Our testers tried more than 10 different whitening strips. Spotlight Oral Care’s strips stood out because they stuck to the teeth well, caused minimal sensitivity after multiple uses, and were easy to apply and take off.

The testers mention the packaging is high-quality and includes a carrying case. The comforting gum oil was also a nice addition (apply for 5 minutes after using the strips to reduce discomfort).

What’s Included:

• 14 treatments total — 28 teeth whitening strips (14 upper; 14 lower)
• Carrying case for the strips
• Comforting gum oil pen to reduce discomfort

Opalescence Go (10% Peroxide) is our top pick for prefilled whitening trays because they’re extremely convenient and easy to use.

Of all the whitening products we tested, these were the most comfortable. The trays adhere to the teeth instantly and cover your entire smile (not just the front six teeth). This provides more even whitening results.

What Our Testers Say

Our testers said no gel leaked through, and the trays stayed in place during the treatment sessions. Whitening strips often leak midway through treatment, but these trays didn’t. Overall, the quality of these whitening trays is superior to any whitening strip or tray they tested.

What’s Included:

• 14 treatments total — 28 teeth whitening strips (14 upper; 14 lower)
• Nice carrying case for the strips

How We Test and Choose Products

We spent over 100 hours testing products in-house, talking to licensed dental professionals, and reading peer-reviewed studies on at-home whitening.

Our testing process is extensive and includes the following:

Testing Standards

Our testers used and compared about three dozen teeth whitening products, including kits, LED kits, strips, pens, and toothpaste.

The testers have been using at-home teeth whitening products for a combined period of 10 years. They’ve also been running the content section of NewMouth’s whitening section for 3 years. One of them has extremely sensitive teeth, so he was the test subject for sensitivity.

The recommendations in this article are based on first-hand use. We only recommend whitening products that our team has thoroughly tested.

• If a product was difficult to use or caused unpleasant side effects, we tested it again to ensure it wasn’t related to ‘user error’
• If we liked a product, we tested it several more times to ensure our findings were accurate and trustworthy

Approval Process

Our testers used each product extensively and compared them based on the following categories:

1. Method of application (i.e., strips vs. LED kits vs. pens)
2. Sensitivity level (and other side effects like gum discomfort or tongue burning)
3. Safety (does the product have a safe bleaching agent ratio?)
4. Ingredient quality (toxic vs. nontoxic ingredients)
5. Ease of use (did the product stay on the teeth?)
6. Length of use (long vs. short treatment times)
7. Duration of use (how often do you use the product to maintain results?)
8. Instruction clarity (were the instructions listed clearly on the product packaging?)
9. Pros and cons (after testing, which products had more pros than cons?)

Meet the Experts

In addition to our own research, we talked to three dental professionals for expert advice. They provided insight regarding the safety of at-home whitening, ingredients to look for and avoid, and how to choose the right product for your needs.

1. Dr. Khushbu Aggarwal Gopalakrishnan, DDS — One of NewMouth’s in-house dentists
2. Dr. Gurpreet Sidhu, DDS —A dental practice owner at Lighthouse Dental Centre in Langley, BC, Canada, with over 20 years of experience
3. Dr. Kate Zoumboukos, DMD — Dr. Zoumboukos is part of SW Austin Dental. She’s also a Fellow of the Academy of General Dentistry (fa*gD) and a member of the American Dental Association (ADA)

What Makes a Whitening Product Effective?

According to the three dental professionals we interviewed, hydrogen peroxide is the key ingredient to look for in at-home whitening products.

“Hydrogen peroxide breaks down into water and oxygen. It is the most effective teeth whitener because it oxidizes organic structure and changes how light reflects from the surface,” says Dr. Sidhu.

Many studies have also determined hydrogen peroxide to be a safe and effective whitening agent when used correctly.^3,4

To be effective, whitening products must contain either abrasives and/or bleaching agents. Abrasives work through mechanical action by removing surface stains. Bleaching agents use chemical action to react with the colored compounds in teeth.

Phthalimido peroxy caproic acid (PAP), a new non-hydrogen peroxide bleaching agent, has also shown promising results in being an effective tooth whitener.^{1, 5}

Our General Recommendations for At-Home Whitening

Before getting into specific recommendations, we developed general guidelines based on our experience using various at-home whitening products. Keep in mind that these are opinions. Talk to your dentist if you have any concerns about whitening your teeth.

Here are some of our opinions about at-home whitening:

Better Value

We believe whitening kits offer better value for the money than whitening strips. The results last longer (sometimes a couple of months) after completing a full course of treatment. This is because they often have higher levels of peroxide than the strips.

Whitening strips are a great option if you are on a budget and don’t mind the upkeep. Whitening kits are usually more expensive because they include higher-peroxide gels, trays, LED lights, etc.

Better Results Than Pens

We recommend whitening strips over pens because they provide more even whitening, aren’t as messy, and require less upkeep. Pens must also be used daily, sometimes twice daily, to maintain results.

We also prefer kits, strips, and pens more than whitening toothpaste (they can be abrasive, and the results aren’t as vibrant). We recommend choosing a product with a low relative dentin abrasivity (RDA) score and using it for maintenance.

Professional Treatment Is Always the Best

Professional, in-office whitening is best if you have severely discolored teeth; one treatment lasts up to a year, and results are immediate.

Talk to your dentist before starting a whitening treatment, especially if you have weak or thin enamel, cavities, tooth decay, or gum disease.

Other Whitening Products We Tested

We tested other products that didn’t make our top recommendations list. However, the products below were easy to use and provided decent results with minimal side effects:

• Burt’s Bees Whitening Toothpaste (good for maintaining bright teeth; ADA approved)
• Hismile PAP+ Whitening Strips (less expensive alternative to Hismile’s kit)
• BURST Whitening Strips (safe and natural ingredients; strips are gooey and slip easily)
• Lumineux Whitening Strips (good for preventing stains and freshening breath)
• GLO Teeth Whitening Kit (messy application; good quality product and gel)
• SmileDirectClub Teeth Whitening Kit (decent product and results; pens are messy)
• Auraglow Teeth Whitening Strips (great alternative to Auraglow’s more expensive kit)

Based on our experience, these products caused unpleasant side effects, lacked convenience, and/or weren’t worth the money:

• Whitening Pens (caused burning sensations in the mouth; require frequent use)
• iSmile Teeth Whitening Kit (caused immediate sensitivity; lacked quality)
• Opalescence 15% Peroxide Kit (peroxide content is too high for at-home use)
• Crest 3D White Whitestrips (caused too much sensitivity to use consistently)
• Crest Whitening Emulsions (messy compared to whitening strips)
• Auraglow Prefilled Whitening Trays (trays are small; not enough whitening gel)

What to Look for in Teeth Whitening Products

When choosing a teeth whitening product, you must consider the following:

Delivery Method

At-home whitening products come in a few different delivery methods.

Dr. Aggarwal recommends starting with whitening strips or kits without lights (like prefilled trays and gels). However, it ultimately depends on your preference and dental health status.

The most common delivery methods for teeth whitening products include:

Prefilled Trays

These consist of potent whitening gels that are ‘prefilled’ into universal trays. One of our testers prefers prefilled trays over other whitening methods for comfort and convenience.

Dr. Aggarwal also recommends prefilled trays because the efficacy of LED lights hasn’t been well-studied. A whitening gel containing an active ingredient like peroxide will whiten your teeth.

Custom Trays

These trays are similar to prefilled options, except they mold to the shape of your teeth and mouth.

You must also manually fill the gel into the trays and put them in warm water before use. One of our testers said there isn’t enough room in many of these trays to fit the whitening gel. They can also be a hassle because they require more time.

LED Kits

LED kits usually come with prefilled trays, with LED lights that shine on your teeth while you have the trays in. The light helps activate the whitening gel and speeds up the process.

Some research shows these lights help speed up the whitening process. Others show the opposite. Our dental experts agree that more studies are needed to determine their effectiveness. However, the mouthpieces do provide a more comfortable whitening experience.

Strips

Whitening strips are the most popular at-home whitening products. You peel the strips from the packaging, dry your teeth, and place the strips on your teeth for 10 to 30 minutes.

Strips peel off quickly and provide vibrant results with consistent use. They are typically cheaper and contain lower peroxide levels than other at-home products.

Pens

Teeth whitening pens are marketed as a convenient way to whiten teeth on the go. It doesn’t require lights or strips. All you do is ‘paint’ your teeth surfaces twice a day.

We don’t recommend pens in this article because our testers experienced more burning sensations with these products. They’re also significantly messier than other options. We only recommend using pens for upkeep between whitening sessions.

Toothpaste

Whitening toothpaste is also a good option for maintaining whitening results after using strips or trays. They usually have gentle abrasives and polishing agents that lightly scrub away surface stains.

If you’re using a whitening toothpaste, we recommend choosing a product with a low Relative Dentin Abrasivity (RDA) score.

Professional Application

Dentists and their dental teams administer and oversee professional teeth bleaching systems.

Compared to at-home whitening products, these procedures are more expensive but provide stronger bleaching agents. This means they whiten teeth faster and produce longer-lasting results.

Application Time

Depending on the product, treatment times can fall between 10 and 60 minutes per session. Most recommend 7 to 14 days of consistent use, then repeating the process every few months. Others recommend 14+ days of treatment.

Generally, the higher the peroxide level, the shorter the session. If you have sensitive teeth or thin enamel, check your progress after a few days of use. Take a break or try something different if you experience discomfort.

Active Ingredients

According to experts interviewed in this article and our research, the following active ingredients are effective whitening agents:

• Bleaching agents like perlite, hydrogen peroxide, and carbamide peroxide (dissolve stains via a chemical reaction).
• Abrasives like hydrated silica and calcium carbonate (scrub away stains).
• Peroxide alternatives like phthalimido peroxy caproic acid (PAP) also cause a chemical reaction (oxidation) to dissolve and break down stains.

Ingredients to Avoid (Common Allergens/Irritants)

We asked licensed dentists to list common ingredients to avoid in whitening products, including potential allergens and irritants.

Here’s what they recommend avoiding:

• Sodium lauryl sulfate (SLS) can cause an allergic reaction and gum peeling.⁶
• Propylene glycol and certain flavoring agents can also cause allergic reactions.⁷
• Alcohol (found in some mouthwashes) can dry out the mouth significantly.⁸
• Cocamidopropyl betaine is associated with cell death.⁹
• Other toxins include desensitizers, anti-plaque agents, anti-inflammatory agents, anti-odor agents, preservatives, artificial colors, and essences.⁹

Brand Track Record

Another factor to consider when choosing a whitening product is the brand’s track record. Ask questions like: How old is the company? How many reviews do they have? Where was the product made?

Dr. Sidhu says to be careful with ‘overseas’ whitening products, as the whitening agents can contain contaminants or dangerous levels of peroxide and may not be approved by the FDA.

Bleaching Concentration

According to Dr. Aggarwal, “the stronger the peroxide concentration, the more effective the whitening product. However, this also increases the likelihood of developing adverse effects.” The most common effects include tooth sensitivity and gum discomfort, which are usually harmless and short-lived.

Methods with longer application times (whitening strips) will be more effective than those with decreased tooth contact (mouthwash and toothpaste). She recommends avoiding products with sodium lauryl sulfate (SLS) and alcohol, as these can have adverse side effects.

At-home products containing higher levels of peroxide, which is common in whitening kits, should be used cautiously. Follow the instructions carefully.

Also, people with weak or worn-down enamel and sensitive teeth should use products with lower peroxide levels. Talk with your dentist before starting a new whitening regimen.

LED vs. No Light: Do Lights Actually Work?

The dentists we spoke to had mixed opinions on the effectiveness of LED lights in whitening. Research results are also conflicting.

For example, one study reported a larger difference in bleaching with an LED light after the first session than without it.¹² Other studies state that using an LED light made no difference with higher hydrogen peroxide concentrations.¹⁰

According to Dr. Zoumboukos, LED lights accelerate the bleaching product’s reaction on the teeth. The LED light itself will not whiten teeth.

Professional Whitening Lights vs. At-Home Lights

There are also key differences between using at-home LED whitening systems vs. in-office light-based ones, says Dr. Zoumboukos. Typically, office products differ in bleach concentration, the type of bleach, and the light system.

Many in-office bleaching systems use higher concentrations of bleach, resulting in an immediate whitening effect. This is not the case with at-home products; results usually take longer to notice.

Current independent research supporting LED at-home whitening systems is not widely available. More studies are required to determine these products’ effectiveness and overall value.

Is At-Home Teeth Whitening Safe?

At-home teeth whitening is generally considered safe if you:

• Follow the product instructions
• Don’t overuse it
• Choose the right delivery method for your needs.

You’ll likely benefit from ‘gentle’ whitening strips or a peroxide-free alternative (like PAP) if you have thin enamel.

“If you overuse the gel, it can cause decalcification of teeth leading to increased wear and cavity susceptibility,” says Dr. Sidhu.

ADA Seal of Acceptance

Choosing products with the ADA Seal of Acceptance will ensure you purchase a safe and effective product.

Here’s a list of the accepted whitening products:

• Crest 3D White Whitestrips
• Crest 3D Whitestrips
• Crest 3D Whitestrips Gentle
• Burt’s Bees Whitening Toothpaste
• Colgate Total SF Whitening Toothpaste
• Crest Gum & Enamel Repair (Advanced Whitening) Toothpaste
• Crest Gum Detoxify (Gentle Whitening) Toothpaste

An oral health product submitted to the ADA must include data from clinical and/or laboratory studies. These tests must demonstrate safety and efficacy according to category requirements developed by the ADA Council on Scientific Affairs.

“I always recommend products with the ADA Seal of Acceptance,” says Dr. Zoumboukos. “None of the at-home LED whitening kits currently have the ADA Seal of Acceptance. The Seal of Acceptance process takes time, and the products are thoroughly evaluated.”

What Type of Whitening is Right for You?

All the dentists we spoke to said it’s important to discuss whitening with your dentist before starting at-home whitening or professional bleaching.

“There is a risk that your teeth or gums will become sensitive to the bleach solution,” according to Dr. Zoumboukos. “Teeth bleaching will not alter the color of your existing dental restorations, and discussing with your dentist possible outcomes before starting any treatment will help clarify possible outcomes.”

In addition to professional recommendations, choose a teeth whitening procedure that works for your lifestyle. Professional bleaching is a good option for those who want immediate results. But at-home solutions are more convenient.

Summary

There are various whitening treatments available right now. From at-home treatments to professional whitening procedures, there is something to help you achieve brighter and whiter teeth.

Keep in mind to always consult a professional to know if a whitening solution is suitable for you. They can assess your teeth’s health and provide the best suggestions.
