We have the technology to remove decay with an air abrasion unit that sprays particles of abrasive sand under pressure to remove decay without drilling.
By using this high pressure sand (aluminum oxide or baking soda), we can remove the decay without removing sound tooth structure.
Because there is no cutting, no anesthesia is necessary.
An additional advantage of this treatment is the elimination of heat, sound and water flow necessary for conventional preparation of teeth with a drill.
