With air abrasion, a fine, pressurized stream of microscopic abrasive powder is propelled at your tooth. The system can be compared to a minature sand blaster, removing small worn fillings, discoloration, stains and small amounts of decay as the power strikes your tooth.
The Advantages of Air Abrasion
We can't use air abrasion to remove decay between teeth, or to prepare a tooth for a large filling, a crown or silver amalgam filling. However, air abrasion is a great option when the decay is shallow or small, and it often allows us to avoid anesthetic or "drill."
