Teeth Whitening Kit Buyer’s Guide

Now that we’ve given you a quick view comparison table of the different teeth whitening kits along with in-depth reviews for each, we’ll go over everything you need to know about teeth whitening kits.

Types of Teeth Whitening Kits

Gel and Tray

One of the more popular types of teeth whitening kits is the gel and tray method. This type of kit makes it easy to whiten every tooth in your mouth at the same time because of the tray molds to each tooth. Once you’ve put the whitening gel on the tray, you want to be careful that you don’t overfill them because the gel tends to liquify from the heat of your mouth. One of the biggest advantages of this whitening method is you can specify exactly which teeth you want to whiten, and you can skip teeth if you need to.

LED Light

If you’re looking for a fast way to whiten your teeth, the LED light-based whitening kits may be the best teeth whitening method for you. You start the whitening process by ensuring the trays fit your mouth comfortably and snugly. Once you’ve got a secure fit, apply a small amount of gel to the tray and bite down gently to secure it. Next, take the LED light and either attach it to your tray or hold it with your lips. This kit is popular for people who are looking for a fast and effective way to lessen or remove stains on your teeth.


Since the early 2000s, the most popular form of teeth whitening kits has been the strips. These whitening strips are made out of thin, flexible, clear plastic that contains a light layer of hydrogen peroxide gel. You peel these strips off and place them hydrogen peroxide side down against your teeth. Make sure the edges seal and watch them go to work. You should see foam or bubbles against your teeth. When the time limit is up, simply remove the strips, brush your teeth, and go about your day. People with slightly stained or yellow teeth like to use these strips.

Things to Consider When You Choose a Whitening Kit

Before you go out and buy a whitening kit, there are a few points you should consider to ensure you get the best kit to suit your needs.


If you’re a person who has a budget you have to consider, this will factor heavily into which kits you can get. If you have a budget between $25 to $45, you can get one of the highest-quality whitening strip kits. If you don’t want to spend over $30, you can get a decent-quality gel and tray kit as they’re typically the least expensive option. Finally, if you want an LED light whitening kit, you’ll usually spend between $30 and $70 depending on the brand.

Ease of Use

You can use whitening strips, trays, and LED light kits at home without any assistance from a second person. Arguably, the whitening strips are going to be the easiest type of kit to use as the gel is already on the strips, and you simply apply them to your teeth and remove them when the time is up.

The gel and tray kits are slightly more challenging as you have to have a specific amount of gel in the trays. If you have too much, your tray might overflow, and if you put in too little your teeth may not whiten evenly.

The LED light whitening kit can be the most challenging to use depending on whether or not the LED light attaches to the tray or not. If it doesn’t, you have to hold it up to your teeth by your hand or by your lips, and this can be challenging to do for 30 minutes.

Sensitivity Level

Before you go out and buy a specific kind or brand of teeth whitening kit, you want to take your teeth’s level of sensitivity into account. The main ingredients in whitening kits are Hydrogen peroxide and Carbamide peroxide, and these ingredients help to lift stains. If your kit has Hydrogen peroxide, you want it to have between 6 percent and 14 percent. If it is higher than 14 percent, your teeth could become more sensitive. If you have sensitive teeth, be sure to consult your dentist before you use a whitening kit.
