Carbamide peroxide and hydrogen peroxide are common bleaching agents used for this purpose in concentrations ranging from 3% to 25%. Treatment must be carefully monitored to avoid overbleaching and damage to surrounding soft tissue.
The act of cleaning the teeth and gums by using a soft brush specifically designed for this purpose. The toothbrush consists of tufts of soft, synthetic fibers or natural bristles mounted in a handle that may be straight or angled for better access or brushing action. It is usually used with fluoride toothpaste (a mildly abrasive, flavored dentifrice) in a manner suggested by dentists and dental hygienists as being a suitable method for cleaning. The proper use of a toothbrush stimulates periodontal tissue.
