Hi, I’m 18 and recently my tooth has been feeling numb. I’m going to make an appointment to the dentist about it, however I’m scared if I do, they’ll take it out which I really don’t want as it is right at the front of my mouth. This all started when I got a ulcer about 4 days ago and the ulcer was rubbing right up against the tooth that now feels numb. Does anyone have any idea why my tooth is numb? And what news I should prepare for at the dentist?
