Bleaching is a procedure that brightens teeth that are discolored, stained or darkened because of injury. It can be performed on all types of teeth, even those that have root canal treatment. A chemical oxidizing solution is applied to the teeth and may be activated by heat or a combination of heat and light or a bleaching tray may be custom fabricated and used at home for approximately one hour per day for one to two weeks. The advantages of bleaching are that it’s economical and does not require tooth removal. Occasional touch-ups may be necessary to keep the teeth white. Currently, Orono Dental Care offers Zoom 2 one visit bleaching, traditional bleaching trays, and Professional Crest White Strips Supreme as our bleaching options.
