From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
For the Toothache.
St. Peter stood under an oak tree. Then spake our beloved Redeemer to Peter: Why art thou sad and weary? Peter replied: Why should I not feel sad and dread, since all the teeth decay in my head. Whereupon our Lord Jesus Christ spake unto Peter! Peter, hie to the cool and lonely nook, there runs a clear water in a mountain brook. Take water thereof in thy decaying mouth, and spew it again into the running brook, + + + This done three times in succession, and each time the three highest names pronounced. This repeat for three days in succession.
The grimoires The Book of Forbidden Knowledge Romanus-Büchlein Egyptian Secrets of Albertus Magnus lists this spell.
