There are several different options for choosing at home teeth whitening kits. While most kits have the same goal, to whiten the teeth, not all kits are made the same. Some kits contain gels while others contain strip or trays. In addition to the materials inside of the kit, the time period in which the kits are used also differs. Some over the counter teeth whiteners are carried out in seven day sessions while others only require three days of application for full results.

The most common types of at home teeth whitening kits are those that contain gels, strips, or trays. Whitening kits with gels contain a gel with whiter ingredients. This gel is applied to the teeth and allowed to dry. The gel is then rinsed from the mouth to reveal a lighter shade of teeth. The amount of gel used is determined by the user.

Whitening strips are another option for gaining whiter teeth at home. These kits contain whitening strips. The strips have been pre-pasted with a whitening ingredient. The kits have strips for both the top and bottom teeth. Some strips are left on the teeth for a designated amount of time then removed. Other strips are designed to dissolve in the mouth and do not need removal.

The last most common type of home teeth whitening kit contains trays. The trays are pre-filled with whitening gel. The trays are placed in the mouth on both the top and bottom teeth. The trays are held for a specified amount of time and then removed.

The best type of whitening kit that is chosen is typically based on the preference of the user. Factors such as time, gag reflex, and teeth cracks and crevices often come into play on which kit is the most effective. It may be necessary to try a variety of whitening kits before determining which kit best suits your needs.
