There are several options for brightening your smile beyond teeth whitening strips. They include:
- Tray-based teeth whitening kits. These kits include a whitening gel and a tooth tray or mouthpiece. You can buy tray-based teeth whitening kits at retail stores without a prescription or purchase one from your dentist. A dentist will take a mold of your teeth and create a custom-fit tooth tray. A store-bought kit comes with a standard tooth tray. These kits require you to apply gel inside the tooth tray, then put the tray inside your mouth and press it against your teeth. As with teeth whitening strips, you keep the tray in place for a certain length of time. You must use it daily, typically for several weeks.
- Laser teeth whitening. This tooth whitening procedure is performed by a dentist. After cleaning your teeth, the dentist coats them with a whitening gel. Next, the dentist shines a laser or other light source on your teeth, which activates a bleaching compound in the gel. Laser teeth whitening takes just an hour or so, but is considerably more expensive than teeth whitening strips or tray-based teeth whitening kits.
