Dental bleaching, also known as tooth whitening, is a common procedure in general dentistry but most especially in the field of cosmetic dentistry. A child's deciduous teeth are generally whiter than the adult teeth that follow. As a person ages the adult teeth often become darker due to changes in the mineral structure of the tooth. Teeth can also become stained by bacterial pigments, food-goods and tobacco. Certain antibiotic medications (like tetracycline) can also cause teeth stains or a reduction in the brilliance of the enamel. Tooth bleaching is not a modern practice.
There are two types of teeth whitening: in-office and take-home.
In-office treatment can brighten your teeth significantly. Using a special, light-activated whitening gel, this procedure is a quick and convenient way to achieve the smile you've always wanted.
Tooth whitening is a procedure that can lighten the shade of your teeth and remove stain or discoloration caused by aging, certain medications, tobacco, coffee, and tea. Tooth whitening will not last forever, so the procedure will have to be repeated on a regular basis.
