We use air-abrasion, a process in which a fine, pressurized stream of aluminum oxide powder is used to remove the small decayed pits and fissures in teeth.
During air abrasion, an instrument that works like a mini sandblaster is used to spray away decay. A fine stream of particles is aimed at the decayed portion of the tooth. These particles are made of silica, aluminum oxide, or a baking soda mixture and are propelled toward the tooth surface by compressed air.
Is Air Abrasion Safe?
Yes. The only precautions needed before air abrasion are protective eye wear (to prevent eye irritation from the spray). The suctioning of particles also prevents them from being breathed into the lungs.
What Are the Advantages of Air Abrasion?
Compared with the traditional drilling method, the advantages of air abrasion are many and include the following:
- Air abrasion generates no heat, sound, pressure, or vibration.
- Air abrasion reduces the need for anesthesia, particularly if the cavity is shallow.
- Air abrasion leaves much more of the healthy tooth tissue behind.
- Air abrasion reduces the risk of microfracturing and chipping of the tooth, which can lead to premature restorative failures.
- Air abrasion is relatively simple and quick.
