Air Abrasion
 |  | | Your third set of molars are no different than any other tooth, save for the fact that they are the last to erupt, or grow, into the mouth. Because they typically do so at around the age of 18 to 20, when adolescents are close to turning into adults, these teeth are commonly referred to as "wisdom teeth." |

| Many people associate the high-pitched whirring of a dental drill with pain. Just the sound alone can make many people wince.
A relatively new technique called air abrasion uses powerful particles of aluminum oxide to remove debris and decay. The most exciting thing for patients is that air abrasion is painless and, in some cases, doesn't require an anesthetic.
Air abrasion leaves behind a gritty feeling in your mouth, which is simply rinsed away almost instantaneously using a small suction device.
Tiny cracks and imperfections on a tooth can be fixed using air abrasion. Although air abrasion is not suitable for work on crowns and bridges, it is often used for bonding procedures, and on tooth restorations involving composite, or tooth-colored fillings.
