Tooth Whitening

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 teethare 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, as the enamelbecomes less porous.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. Ancient Romans, for example, utilized urine as a product to make and keep their teeth whiter.
