Air abrasion is actually an older technological development: it was first attempted in the 1940s, although it was side-stepped for the air rotor (better known as the "drill"). By the twenty-first century, however, air abrasion technology has significantly developed and dentists like Dr. Suyama have reintegrated this technology into their practices.
Most air abrasion systems blow 27 micron aluminium oxide powder using compressed air.. The compressed air and powder is directed towards the tooth and would not cause any pain. It also removes smaller white fillings, although it is not recommended for removing silver fillings.
Benefits:
An atraumatic alternative to the high-speed drill, air abrasion can be completed in less time without the need for "freezing" patients' teeth. Patients respond extremely favourably to this method because there is minimal invasiveness: there is no pain, no vibration, no heat, no smell, and no noise! Patients may also enjoy the fact that air abrasion can be used to remove smaller areas of tooth decay before a hole is visible—it prevents substantial tooth decay from setting in.
