Going to the dentist seems like a fairly mundane activity. You have your teeth cleaned, you lie about flossing, and occasionally they find a cavity. You would never expect that the person who had their hands inside your mouth for the better part of an hour could be a cold hard killer. Many murdering dentists have gone to extensive lengths to kill those close to them, and a few simply made deadly mistakes.
From serial killings to crimes of passion, these murders show that nobody can be trusted, not even your doctor.
