Air abrasion

Air abrasion is a newer technique that is used to remove tooth decay – it’s like a mini sandblaster and is used to spray away decay.

During the procedure, a fine stream of particles is aimed at the decayed portion of the tooth. These particles are made of aluminium oxide, which are propelled toward the tooth surface by compressed air that runs through the dental handpiece. Small particles of decay on the tooth surface are removed as the stream of particles strikes them. The particles are then removed using a high speed suction system.

Compared to the traditional drilling method, the advantages of air abrasion are many:

• The procedure generates no heat, sound, pressure or vibrations.
• It reduces the need for anaesthesia, particularly if the cavity is shallow.
• It leaves much more of the healthy tooth structure behind.
• It leaves the working area relatively dry, which is an advantage during the placement of composite fillings.
• The procedure is relatively simple and quick.

Air abrasion is ideal for use in children and others who are fearful of the drill and have minimal decay.
