Enamel microabrasion in dentistry is a minimally invasive cosmetic dental treatment that involves removing a thin layer of enamel from the teeth using an acidic abrasive material. The procedure is used to remove superficial stains and discolourations from the teeth that are resistant to traditional whitening treatments, and to improve the appearance of teeth with superficial enamel irregularities and discolouration defects. Microabrasion may be helpful for brown, yellow or white stains or spots associated with conditions such as enamel fluorosis, hypomineralisation, decalcified areas around orthodontic brackets and other marks that do not respond to bleaching alone. Microabrasion may be used before and/or after dental bleaching to achieve uniform tooth colour for these types of difficult to treat teeth.

The exact cause of geographic tongue is unknown, but it is believed to be related to an immune system reaction. Some factors that may increase the risk of developing geographic tongue include a family history of the condition, stress, hormonal changes, and certain dietary factors.
