Has anyone ever had a problem with their lip twitching- kind of like a muscle spasm? Could it have been from a shot at the dentist office? I just had my first cavity filled about 2 months ago and the twitching started a couple weeks after in my top lip. It's been going on for a month and it is so irritating!
