Definitions for "Air Abrasion"
The use of air and an abrasive (usually tiny particles of aluminum oxide air-blasted in a stream of air) to remove tooth structure, such as decayed debris and ruined enamel of cavities. This is a relatively new technology in dentistry that often avoids the need for anesthetic with smaller fillings
If your teeth are slightly discoloured your dentist may be able to remove stains within the top surface (enamel) of the tooth, with air abrasion. The procedure is a little like 'scuffing' the enamel but no long term damage is done as the area re-mineralises very quickly. This is a simple approach and can give a dramatic change.
The use of air and an abrasive (usually tiny particles of sodium bicarbonate or aluminium oxide) blasted in a stream of water to remove tooth structure or surface staining depending upon the particulate stream used.
