A bright, white smile is something that many people desire. It can boost confidence and leave a lasting impression on others. While professional teeth whitening treatments can be expensive, at-home teeth whitening kits offer a more affordable and convenient solution.

Sipping on coffee, tea, and wine contribute to the discoloration of teeth. Teeth staining foods, genetics, aging and other lifestyle factors can cause our pearly whites to devolve into a more yellow hue. To get the glimmer, shine, and wonderful white back, you can turn to at-home teeth whitening products, instead of finding yourself under the bright lights, in the dentist’s chair.

There are many at-home teeth whitening kits on the market, each promising to deliver a whiter, brighter smile. With so many options available, it can be overwhelming to choose the right one for you.

We will consider factors such as effectiveness, quality, ease of use, safety, and price to determine which products are worth your investment. Whether you have stains from coffee, wine, or tobacco, or just want to brighten your smile, this article will help you find the best at-home teeth whitening kit for your needs that works.

In this article, we will compare the top 7 at-home teeth whitening kits to help you make an informed decision.

WhiteWash Teeth Whitening System

WhiteWash, a well-known brand, came in as the best teeth whitening kit contender, from the work done by our researchers and testers, and also recommendations from many dentists. Not only were they impressed by the topnotch whitening results, they found the product easy to use with its patented ergonomic design tray, and the treatment time quick and easy. Some were concerned with possible sensitivity, as that can be common in this type of product, however with the BrightSmile system, no sensitivity was reported.

The number one feature that separates WhiteWash teeth whitening kit from other brands on the market is its smart 20x 3D Pro LED Light technology, the most powerful at home teeth whitening light ever for maximum whiting results.

BrightSmile is the only brand on the market that offers the most powerful at-home teeth whitening light, and when it comes to teeth whiting, the light is the #1 essential element for a fast and best whitening result.

When using products in the mouth, care must be taken with formulation and ingredients, as some ingestion may be inevitable. Our researchers and tester felt very comfortable with the FDA approved, vegan, paraben-free, gluten-free, non-GMO formula. Above all, they were ecstatic with the results and the ability to quickly touch-up the teeth with the portable teeth whitening pen alongside other teeth whitening products they offer.

WhiteWash is based in the UK, and they offer fast shipping and a 120-day money-back guarantee.

WhiteWash Before and After

Smile Teeth Whitening Kit

Smile Direct began as a teeth aligner company, and has since added their teeth whitening products. While our researchers and testers loved the hands-free feature and that they could utilize their smart phone to power the LED lights, they felt that this product was treated like an after-thought given the difficulty of navigating the Bright On™ portion of the website.

While they did see results and liked the quick 5-minute treatment time, some of our testers were turned off by the production of excess foam in the mouth. They did allot some praise to the no-mess brush applicator that did a good job keeping the gel off of hands and teeth.

AuraGlow Teeth Whitening Kit

Aura Glow touts the use of dental grade ingredients including Carbamide Peroxide. Our researchers and testers were drawn to the high quality, professional grade ingredients, however they felt the 30-minute treatment time was long compared to other brands. They did like the whitening results and the 30-day money back guarantee. Although the treatment time was a lot, they only required one treatment to see results.

HiSmile Teeth Whitening Kit

Compared to other brands with 20 LED lights, HiSmile only contains 5. This was the first red flag for our researchers and testers. However, they were intrigued with the inclusion of anti-inflammatory and anti-bacterial ingredients in the formula. With an average result of 3.5 shades whiter than the starting point, our testers were a bit disappointed and longed for a brighter finish. 

iSmile Teeth Whitening Kit

The iSmile Teeth Whitening Kit can be used once a day for 10 minutes to remove stains from coffee, wine, soda, smoking, and more with 5x LED activated acceleration technology. Results may take longer that expected compared to other brands due to weak LED activated device.

Caliwhite Teeth Whitening Kit

Created in California, this product touts the use of clean ingredients, a feature that attracted our testers and researchers to the kit. While some reported that the universal tray was quite uncomfortable they were relieved that the kit cam with a molding tray, yet it did create extra work. The results were apparent and the teeth did whiten significantly, but some reported the appearance of white dots on the teeth after treatment. While the treatment outcome was impressive, it was more difficult to reach the desired effect than some of the other brands.

GLO Science Teeth Whitening Kit

GLO produces at-home teeth whitening kits as well as professional kits used by dentists. This caused some concern among our researchers and testers regarding the actual strength of the at-home product. While some results were positive and produced a distinguishable whitening effect for some, others lacked the appearance of whiter teeth. Our research crew liked that the product was FDA registered and did not cause sensitivity. They were however disappointed with the 4 hour charging time for the LED device.
