How to Pick the Right Teeth Whitening Gel

You may have noticed that there is a wide variety of teeth whitening gels on the market. Not only is there a difference in teeth whitening gel brands, but you’ll also notice that there is a difference in the percentage of active ingredients in these gels. Here is some advice to help you select the right Teeth Whitening Gel kit for your needs and goals:

Understand how teeth whitening gels work

No matter what type of teeth whitening gel you select, the teeth whitening gel works generally the same way across the board. Essentially, you apply the teeth whitening gel to the surface of your teeth. Over a period of time, the active ingredients in the teeth whitening gel lighten your teeth. The major differences in teeth whitening gels have to do with how the gels whiten your teeth, application methods, and strength.

Differences in teeth whitening gel ingredients

The difference in teeth whitening gel ingredients is very basic: teeth whitening gels will either use a hydrogen peroxide active ingredient or another form of active ingredient. Hydrogen peroxide variations are, basically, bleach. These teeth whitening gel solutions provide a comprehensive teeth whitening solution because they actually change the color of the natural teeth by bleaching the stains within the teeth pores (intrinsic stains) as well as the stains located on the enamel of the teeth (extrinsic stains).

Other teeth whitening products, such as teeth whitening toothpastes, only affect the extrinsic stains and, therefore, are not as comprehensive. Most effective teeth whitening gels feature the bleach composition and are, therefore, one of the most effective teeth whitening solutions available on the market.

Application methods

When it comes to applying teeth whitening gels, one of the most common and effective methods is to use bleaching trays. The teeth whitening gel kit that you select will generally come with trays that you can mold to fit your unique mouth structure. In order to use these teeth whitening gel kits effectively, simply line the tray with a thin layer of the teeth whitening gel (the gel will spread out once you apply the tray to your teeth), and insert the tray into your mouth according to the directions. You will use one tray on your top teeth and one tray on the bottom.

There are other methods to apply teeth whitening gels as well, including products such as Crest Whitestrips and brush-on methods. However, when working with teeth whitening gels, trays are the most common application method…and they can be used overnight!


The strength of the teeth whitening gel that you select will be based on a variety of factors. There are four main strengths: 35%, 22%, 16%, and 10%. The higher strength gel is effective in less amount of time than the lower strength gels, but can be too sensitive for many people to use. The lower strength teeth whitening gels is as effective as the higher strength gels when used for a longer period of time and it is a great option for people who have sensitivity to the higher strength teeth whitening gels.

In most cases, people who use teeth whitening gels will insert trays overnight. Most dentists recommend wearing the trays for up to 4 hours, as the active ingredient remains active for up to 4 hours. However, if you are only able to wear the trays for a short period of time, you may want to opt for a higher strength gel, which can be effective with just 15 minutes of use a day.

You’ll find that teeth whitening gel kits are easy to use, affordable, and barely noticeable – especially when you wear them overnight. For more information about our teeth whitening gel options or to get started with your order, contact us today!
