The air abrasion instrument works like a mini sandblaster to spray away the decay, stain, or to prepare the tooth surface for bonding or sealant application. With air abrasion, a fine stream of particles is aimed at the tooth surface. 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 hand-piece. Small particles of decay, stain, etc., on the tooth surface are removed as the stream of particles strikes them. The remnant particles are then "suctioned" away.
