Air abrasion
Air abrasion is a dental technique that uses compressed air to propel a thin stream of abrasive particles—often aluminum oxide or silica—through a specialized hand-piece to remove tooth tissue and decay before being suctioned away, similar to sand blasting. It can be used in a variety of dental procedures, including removing tooth decay, stains, and old restorations, as well as to prepare teeth for new restorations, sealants, and bonding.
