The tongue is the most frequent source of cancers in the mouth, followed by the floor of the mouth, soft palate tissues in back of the tongue, lips, and gums.
Bleaching and non-bleaching products are the two basic kinds of whitening products available today.
Non-bleaching products normally use abrasives or chemicals and only remove surface stains on teeth.
Bleaching products work with a chemical called peroxide and can brighten your teeth several shades.
Another process employs the use of a special gel that is placed inside a flexible device you wear around your teeth for a certain period of time. After you remove the device, you must use a second bleaching agent, followed by a special light to activate the chemical action.
Mildly stained teeth usually only require one session of bleaching.
