Your teeth can be brightened through a treatment called laser teeth whitening or custom-made tray-based whiteners. Concerning the laser whitening, teeth are treated with a bleaching gel during the operation. The gel is then heated by a laser that is pointed at your teeth. This turns on its teeth-whitening abilities and changes the stain molecules there. Laser teeth whitening aims to lessen discoloration and improve the appearance of your teeth. For the custom-made trays, our dentists can make personalized dental trays that fit your teeth. It works by filling a the tray with a gel whitening solution that contains a peroxide-bleaching agent, then wearing the tray for a period of time.
