Yes, i went in to do a specific procedure. But the dentist tried to drill on a different location without telling me what he/she was doing. That to me is illegal. Even if it's on the same location, he/she would have to tell me what he/she was doing. LOL...there's a reason i fear dentist hence need protection.It would only be illegal if the dentist “drilled on you” without your knowledge and consent. If you made an appointment with the dentist for a specific procedure (e.g., to have a cavity filled), the drilling would not be without your knowledge or consent.
You (usually) will sign a consent form when you go to the dentist’s office.
You might have a hard time finding another dentist if you go to a dentist believing the dentist is out to get you. A dentist has a valuable professional license to protect. In the majority of cases, a dentist will not jeopardize this license by violating the rules that govern his profession or by violating the law.
Is the problem more that you are “afraid” of dentists? This is actually not all that uncommon a fear. If so, you might benefit from dealing with this fear first (therapy) before sitting down to have your teeth cleaned or repaired.
