What is Air Abrasion? How does it even work?
Air abrasion is a drill-less technique used by dentists to remove tooth decay and for other needs.

The instrument reflects a mini sandblaster to spray away decay. Particles made of silica, aluminum oxide, or a baking soda mixture are propelled toward the tooth surface by compressed air or gas that runs through the dental handpiece. This removes tooth decay particles as the air strikes them, which are then suctioned away.
