Best Teeth Whitening Kits of 2024, Recommended by Dentists (2024)

What Are Teeth Whitening Kits?

Teeth can become stained or develop a yellowish hue over time from poor dental hygiene or substances like tobacco and coffee. While dentists offer whitening treatments, they can be costly and there are a number of at home options which are cheap and effective. There are a wide range of whitening products on the market including strips, pens, gels, and serums. Even better, many brands offer at-home teeth whitening kits which often combine these products with a LED light therapy device for added whitening and oral care benefits.

Not only do these products and kits whiten teeth, they also help kill mouth bacteria, decrease inflammation, reduce plaque, and lower your risk of gingivitis. Dr. Michael Kosdon, DDS explains the benefits of at home whitening kits:

“LED whitening kits help break down and remove stains that can build up in between whitening treatments. These easy-to-use kits offer an inexpensive and effective way to maintain the whiteness of your smile in the comfort of your own home [1].”

Buying Guide

How do you decide what is the best teeth whitening kit or product to buy? Our team of board certified dental professionals assessed the existing brands according to a set of rating criteria to decide on the leading product.

These are some of the most important factors that they looked at, and you can use this mini guide to do your own research to find the best teeth whitening kit or product.

Brand/Manufacturer Reputation – Very often the best products for teeth whitening come from companies or brands that have a good reputation in the market, and they are more likely to be safe and high quality.

Ingredients – Check the ingredients list carefully before you buy to ensure there are no irritants or harmful additives. When it comes to the active ingredients, check the research to see if there’s scientific support for their efficacy.

Return Policy – Any good manufacturer will give you at least 30 days to decide if you want a refund. For oral care products, however, some brands will only give you your money back for unused items.

Safety – Besides checking the safety of the ingredients, ideally you should buy a product manufactured in an FDA, GMP certified facility that follows rigid safety standards.

Customer Reviews – Reading the user feedback gives you information and insight into the advantages and possible downfalls of each product, so you should always check reviews before making a final purchasing decision.

Cost/Value Ratio – Compare different brands in terms of their cost and the features and benefits offered for that price to get a good idea of the cost-value ratio for each.

How Do Teeth Whitening Kits Work?

Most teeth whitening products like pens, gels, serums, and strips include either hydrogen peroxide or carbamide peroxide as bleaching agents. These compounds whiten the teeth through oxidation, as we said in our review of Arc Teeth Whitening Pen. This does not damage the enamel at the levels included in the products.

A research review by Clifton M. published in the Journal of Evidence-Based Dental Practice discussed the existing knowledge on teeth whitening and deemed peroxide-based products effective and safe to use [2].

These ingredients and others included in whitening products like menthol and ethanol have anti-bacterial properties. They abolish microbes on the teeth and gums, which may prevent the buildup of plaque and reduce your risk of gingivitis.

The products also have anti-inflammatory agents which decrease swelling and speed up healing. In addition, antioxidants eliminate free radicals to lower oxidative stress in the mouth. This can also result in repair and healing.

A scientific publication in Antioxidants by Fan Qi and Haofei Huang, et al examined the advantages of using antioxidants in dental procedures to kill free radicals [3].

Teeth whitening kits like NuBeam often include a blue LED light therapy device that contributes to both whitening and oral care. The products send photons of light to the mitochondria of the cells, increasing levels of ATP.

The resulting energy to all of the cells in the body offers significant benefits for oral health like lessening inflammation, killing bacteria, decreasing infection risk, and removing stains and discoloration from the teeth.

A study published in the Journal of Cosmetic Dentistry by Joe C Ontiveros, et al compared bleaching using 6% hydrogen peroxide either with and without light treatment, and found stronger benefits with the light [4].

Are Teeth Whitening Kits Safe?

High quality teeth whitening products such as the ones we have discussed are safe, and the typical ingredients like peroxide do not harm the teeth enamel at the dosages included in the products.

There is a chance that people with very sensitive teeth and gums could experience some mild irritation, so check to make sure the product you buy is gentle.

If you are looking at other brands, ensure that there are no harmful additives included in the formula. LED light therapy is also safe according to the research, and should not lead to any discomfort or side effects.
