AIR ABRASION This technology uses an air compressor and a special handpiece that emits a fine stream of silica particles powered by a strong stream of air, resulting in virtually no vibration to the tooth. This is used to remove decay in intact teeth that have had no previous restorations. In most instances the patient does not need a local anesthetic because preparation of the tooth is painless and minimal tooth structure is removed. Another use includes the etching of the tooth for greater adhesion before sealants are applied. Back to Topics
