Air abrasion is a drill-less and gentler approach to remove decay from the teeth. An air abrasion unit is a small instrument that blasts a fine stream of air and particles on the teeth to spray away decay. The small particles are made of silica, aluminum oxide or baking soda and aid in cleaning the tooth surface. Air abrasion allows for decay to be quickly removed while still preserving healthy tooth structure. The particles and decay are then suctioned out of the mouth.
Air abrasion is gentle because it generates no heat, sound, pressure or vibration. It also reduces the need for anesthesia, making it an ideal choice for children and those who experience dental anxiety.
