Teeth whitening products that list hydrogen or carbamide peroxide as the main active ingredient are the most effective.
Hydrogen peroxide solutions whiten your teeth by oxidizing them. Most treatments do not cause significant changes in tooth enamel.
However, some treatments can cause tooth sensitivity and enamel changes. This risk increases if you leave the serum on your teeth for a long time. High peroxide concentrations can also cause these issues.
At-home teeth bleaching products that contain 5 to 10 percent hydrogen peroxide or 35 percent carbamide peroxide are considered safe. Make sure you follow the instructions as directed and don't overuse the gels.
Best Overall & Best for Sensitive Teeth

The well-packaged and easy-to-use system delivers a professional-level whitening experience at an affordable price. The serum is enamel-safe for those with sensitive teeth and gums.
GLO Brilliant uses LED lights as well as heat to give you faster results. This kit is for people who want white teeth quickly. Applications only take 8 minutes. They suggest completing four back-to-back applications each day for five straight days, or until you’re pleased with the results. This is a fast and effective whitening process, but it is the most expensive item on our list.
AuraGlow is an easy to use home tooth whitening system that uses an advanced 35% carbamide peroxide whitening solution and led lights to give you whiter teeth. There are approximately 20 treatments included. Use daily for 30 minutes to remove discoloration and gain optimal brightening results.
The Crest 3DWhite Glamorous White Whitestrips Kit contains 16 full whitening treatments. This includes 14 regular whitening treatments (one upper and one lower strip) and two one-hour express treatments. The one-hour express strips reveal same-day results for a visibly whiter smile.
Crest 3D White Whitestrips have the American Dental Association (ADA) Seal of Acceptance, which means they are safe and effective when used correctly.
Best Whitening Option for Travel
The AuraGlow Teeth Whitening Pen will deliver results when you’re traveling or on the go. You can coat your teeth quickly and easily with the ergonomic design. However, we suggest using the AuraGlow Teeth Whitening Kit to increase the whitening effects of this treatment.
Best Whitestrips for Sensitive Teeth
These Whitestrips were developed to provide a comfortable at-home whitening experience for people who have tooth sensitivity but still want to brighten their pearly whites. These enamel-safe strips get applied for 30 minutes daily.
Best Non-Peroxide Whitening Kit
Lumineux Oral Essentials were developed utilizing coconut oil, lemon peel oil, sage oil, and dead sea salt to remove stains from your teeth instead of bleach (hydrogen peroxide). They were developed with dental professionals and are non-toxic, SLS-free, preservative-free, sugar-free, and vegan. Apply the strips for 30 minutes every day and see results in 7+ days.
Lumineux’s Teeth Whitening Kit includes:
Best Whitening Toothpaste
The product contains 2 percent hydrogen peroxide, which dentists recommend for whitening. It also contains fluoride to protect against cavities.
Whitening toothpaste is not as effective at whitening your teeth as LED kits or Whitestrips. But it can help remove and prevent surface stains. Therefore it should be used in addition to one of these other methods.
Best Whitening Mouthwash
Colgate Optic White Whitening Mouthwash contains 2 percent Hydrogen Peroxide. This can slightly help remove surface stains. However, whitening results from mouth rinse alone will not be as effective as an LED whitening kit or Whitestrips.
Because it does help prevent new stains, whitening mouthwash is best used in addition to another whitening product.
Best All-in-One Whitening Brand
This LED whitening kit was designed to reduce sensitivity and uses enamel-safe ingredients. If you're a fan of using the same brand for every step of your oral health routine, you can use Colgate whitening toothpaste, mouthwash, and LED kit.
This kit can be used hands-free, only takes 10 minutes, and doesn’t require a smartphone to use, making it easy to apply.
With centuries of research-based evidence, both over-the-counter and professional whitening methods are safe and effective.
Some products (like LED teeth whitening) are more effective than whitening strips and toothpaste. However, both provide some level of teeth whitening. In-office teeth whitening is the most effective option and provides the longest-lasting results.
The key factor in safety is whitening your teeth properly. Always follow the directions provided by your dentist (or the product label for at-home products).
If you do not follow the directions, you may experience negative side effects. These can include:
LED teeth whitening is safe for at-home use. Current research shows that LED whitening is effective when users follow the manufacturer's protocols.
LED as a light source is a safer alternative to ultraviolet (UV) light, which can cause cell mutations. An LED light does not lead to the mutation of cells or raise the risk of cancer. LED speeds up the whitening reaction without the risks of UV light.
During the LED teeth whitening process, you’ll apply a bleaching agent to your teeth. The LED light activates the whitening agent and starts the chemical reaction. When this reaction occurs, the blue LED light penetrates the enamel and removes stains.

LED lights themselves will not make your teeth whiter, however, they accelerate the teeth whitening agent, so they do play a significant role in many teeth whitening systems.
Teeth whitening strips, LED whitening kits, and professional whitening treatment from a cosmetic dentist are some of the most effective ways to whiten your teeth.
Be sure to speak with a dentist to get a personalized recommendation for whiter teeth. Do not combine products and use them exactly as directed.
GLO Brilliant Deluxe Teeth Whitening Device Kit and Crest 3D White Luxe Whitestrips provide safe, fast results.
According to the American Dental Association (ADA), home teeth whitening kits are safe if used as directed. If they are overused, it could lead to tooth enamel damage.
