Intra-oral sandblasting or “air abrasion” involves firing a pressurised flow of “sand” at the decayed or weakened tooth surface. The weakest part of the tooth is removed first, thereby conserving as much healthy tooth structure as possible. Minimal Intervention is the philosophy of this millennium.
Having your teeth sand blasted sounds awkward doesn’t it? It is, in fact, the opposite. Sand blasting replaces the drill in removing decay from a tooth. This piece of technology works by spraying a stream of particles at the decayed part of your tooth. The particles are made of aluminium oxide, silica, or a baking soda mixture and are propelled at the tooth by either compressed air or gas. Then the particles of decay are then suctioned away through a tube.
Yes. This minimally invasive technique is safe provided the proper precautions are taken. These precautions include wearing protective eye-wear, and a rubber dam or protective resin applied to protect surrounding teeth and gums that aren’t being treated. Suctioning of particles also prevents them from being breathed into your lungs.
When comparing sand blasting to the traditional drilling method the advantages are:
Disadvantages of sand blasting over the drill include:
This minimally-invasive treatment can be used for;
