Abstract

A dental repair process removes an area of tooth decay from a tooth structure, and prepares the tooth structure, including dentin and enamel surfaces of the tooth structure, for bonding with a filler material. It is characterized by the use of a soft abrasive particulate material such as a urea resin with a Mohs hardness in the range of from 3.0 to 4.0 and a particle size of 10 to 200 microns. Such material is capable of effectively removing soft tooth decay when carried in a fluid stream that is directed towards the decayed area under pressure.
