Principle of tooth bleaching The main component of commonly used tooth bleaching agent is 10% concentration of carbamide peroxide, the decomposition of carbamide peroxide produces 3.3% hydrogen peroxide, hydrogen peroxide easily infiltrates into the enamel and dentin, the macromolecular pigment material is decomposed into small molecules, thus making the tooth color lighter.
Bleaching methods: Dental bleaching is currently mainly triage bleaching and home bleaching.
Clinic bleaching is performed with a high concentration of bleach in a special light source, usually 1 to 2 times, each time about an hour.
In home bleaching, a thin personalized tray is made by taking an impression of the tooth, adding medicine to the tray every day, and wearing it for 4-6 hours a day for about 1 month.
Indications FOR BLEACHING: BLEACHING IS BEST FOR formal orange and brown disCOLoration, best for yellowing with age, moderate for mild tetracycline teeth and dental fluorosis.
