A couple of days ago i got hit in the face with an elbow (by accident). Since then my lip wound healed but one of my upper front teeth is still more sensitive than usual. I feel this sensitivity when i put pressure on it (it is not more sensitive when i drink a hot or cold beverage). The "pain" is far from unbearable, but it is very hard to concentrate on other things when i am constantly thinking about my tooth. I was wondering whether i should visit a dentist or will this heal by itself it has been three days since the accident.
