Abstract
A tool bit for removing orthodontic brackets includes a handpiece-engaging portion, a shaft portion, a curved portion and a working end portion. The curved portion provides sufficient offset to present the end portion in a substantially co-planar relationship with a tooth surface. The working end portion includes at least one beveled cutting surface for cutting away the adhesive and at least one blunt/flat polishing surface for polishing away any residual adhesive that may remain after bracket removal. The tool bit may also include a cooling fluid delivery port. Edges of the beveled surfaces may be serrated. Beveled surfaces and the top surface may be coated with an abrasive material such as diamond grit. These cutting surfaces are used to cut through the adhesive layer bonding the bracket to the tooth. The tool has a blunt/flat second edge surface for polishing away any remaining adhesive after bracket removal.
