A method and manufacture for orthodontic bracket application and removal, employing an orthodontic bracket adhesive containing a non-toxic, inorganic filler which is insoluble in mouth fluids and has a Mohs hardness less than about 4.5, together with an abrasive for removal of the adhesive. The abrasive is a non-toxic, inorganic material having a Mohs hardness greater than that of the adhesive filler but less than about 5.

A manufacture for orthodontic bracket application and removal without abrading tooth enamel, comprising: (1) an orthodontic bracket adhesive composition which contacts said tooth enamel, comprising a finely divided first inorganic material admixed with a polymerizable resin, said first inorganic material being non-toxic, essentially insoluble in mouth fluids, and having a Mohs hardness less than about 4.5; (2) a solid abrasive tool which abrasively contacts said orthodontic bracket adhesive composition to effect removal thereof, comprising a second inorganic material, said second inorganic material being non-toxic and having a Mohs hardness which is greater than the Mohs hardness of said first inorganic material and less than about 5. A method for applying an orthodontic bracket to a tooth surface and for removing said bracket therefrom, comprising the steps of: A. cleaning said tooth surface using dental prophylactic paste and an etchant; B. applying a thin layer of sealant resin to said tooth surface; C. coating said thin layer of sealant resin with a layer of orthodontic bracket adhesive composition comprising a finely divided first inorganic material admixed with a polymerizable resin, said first inorganic material being non-toxic, essentially insoluble in mouth fluids, and having a Mohs hardness less than about 4.5; D. applying an orthodontic bracket to said layer of orthodontic bracket adhesive composition and curing said adhesive composition; E. removing said orthodontic bracket at the completion of orthodontic treatment; and F. removing any residual adhesive which may remain on said tooth surface by grinding said residual adhesive away with a solid abrasive tool comprising a finely divided second inorganic material admixed with a solid binder, said second inorganic material being non-toxic and having a Mohs hardness which is greater than the Mohs hardness of said first inorganic material and less than about 5.
