As a person ages the adult teeth often increase in value, that is to say they become darker. This darkening is due to changes in the mineral structure of the tooth, as the enamel becomes less porous. Teeth can also become stained by bacterial pigments, tobacco and food. There are 2 techniques of bleeching. The first involves applying an oxidising agent for a very short period of time (the so called office bleach). This gets fast results but risks chemical burns to the soft tissue and gums. The alternative method involves using a thin mouthguard to hold a low concentration of oxidising agent next to the teeth for several hours a day for a period of several weeks. This is known as home bleaching. This is slower but has the lowest risks to the soft tissue.
