What Is Air Abrasion?
Air abrasion is a drill-less technique that is now being used by modern dentists to remove tooth decay and for other applications.
How Does It Work?
During air abrasion, an instrument that works like a mini sandblaster is used to spray away decay. During air abrasion, a fine stream of particles is aimed at the decayed portion of the tooth. These particles are made of silica, aluminum oxide, or a baking soda mixture and are propelled toward the tooth surface by compressed air or a gas 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 of decay are then “suctioned” away through a thin tube.
