Air abrasion is a technique for cleaning out those dark pits and grooves on the chewing surfaces of your teeth.
Often these pits and grooves are so small that the dental instrument can't feel the decay starting underneath the stained area. The air abrasion machine is a tiny sandblaster. Very conservative fillings are done with tooth-colored material. No anesthesia is required. These "no shot, no drill" fillings can be used only on very small cavities.
