Tooth bleaching trays
Dental bleaching can also be successful thanks to the help of trays. “The whitening gel is kept in place over the surface of the tooth with a tray worn over the teeth” states Dr. Mujtaba (the creator of SaneDentist an info site on dental health and dental hygiene). There are various types of trays that are available such as “one size-fits-all tray” or individual trays specifically created for the definite patient. It’s easy to understand that the special trays are more effective because of a simple reason: they supply the actual fit and the teeth are kept in contact with the special gel. Using this type of bleaching gel usually put is 10-15 percents carbamide peroxide. The tray is recommended to be worn for a certain amount of time in an appropriate manner.
