- Teeth whitening gels are usually applied using a tray (or guard) or a brush (or pen). Once you decide which form of application is right for you, then find the right type for you. For example, if you choose teeth whitening gel applied using a tray, then find the tray that best fits your mouth. If, on the other hand, you choose a teeth whitening gel that's applied using a pen or brush, find the one with the finest tip so you can apply it evenly to your teeth without getting any teeth whitening gel on your gums.
- Do not overdo over overuse any teeth whitening gel; that is to say, only use teeth whitening gels as directed. In directed amounts, teeth whitening gels can be very helpful in whitening your teeth and completely safe and harmless for your teeth and gums. However, in excessive amounts or applied with excessive force or left on for excessive lengths of time, undesired effects could result, like tooth sensitive by eating its enamel away.
- After using any sort of teeth whitening gel, make sure that you rinse your mouth fully with water or an oxygenating oral wash.
