There are two basic ways that teeth whitening gel is applied and different times that the gel needs to stay on the teeth in order to be effective. Knowing how the gel is applied can make it easier to decide between all the different types of gels that are on the market. The application time can also make a difference as many people do not want to spend a great deal of time whitening their teeth and others do not care how long it takes as long as the product works.

The first way that teeth whitening gel is applied is by brush. This application is easy to use and does not involve putting uncomfortable trays that do not fit properly into the mouth. The gel is simply dabbed directly onto the teeth with a brush. Many of the applicators are a single unit that has the gel and the brush in a pen form.

The bottom of the gel pen is twisted and the gel comes out at the brush tip. Once the gel is on the brush, it can be applied to the teeth. With the Colgate Simply White kit, the gel is in a bottle and the top unscrews and is where the brush is located. The brush can be dipped in the whitener and then brushed on the teeth.

Typically, the application and standing time are less with the brush on gels than they are with other methods. The time can range from thirty seconds to five minutes before the mouth needs to be rinsed out. Most gels recommend no eating, drinking or smoking for a half an hour after application to ensure that the gel has been effective in the whitening process.

The second method for using teeth whitening gel is to use a tray to apply the gel. It is important to find a kit that allows for the trays to be custom fitted to the mouth so that they trays are not uncomfortable. Once they are fitted, the gel is lightly dabbed on the tray and the trays are inserted to fit over the teeth.

Watts Power White offers an affordable tray system that comes with form fitting trays to keep the gel on the teeth more effectively and more comfortably. There are other brands of the teeth whitening gel on the market that work just as effectively and the type that is purchased is going to mainly depend on how much whitening is needed and the application style that is preferred.
