A dentist advisor system includes signaling apparatus by which a patient can non-verbally advise a dentist to interrupt or terminate a dental procedure being performed by the dentist positioned on one side of the patient, and a selected tactile surface selectively operatively associating the signaling apparatus with the hand of the patient on the side of the patient opposite the dentist. Thus the patient's associated selected hand is opposite the dentist during performance of the procedure, and thus use thereof does not interfere with the dentist.
