My front tooth is sensitive and sends a sharp pain when in contact with other teeth. also, the gums above it feel numb and feels like it's an air sac?

See a dentist: Could be a number of problems. The tooth must be evaluated by a dentist who can examine, take x-rays and make appropriate suggestions.

Needs evaluation: Could be an endodontic or periodontal problem. Cannot tell without an exam and radiographs or knowing the condition of the tooth. See a local dentist.

Infection: May be gum infection, tooth infection, or combined lesion. Please see your Dentist. The sooner this is treated the less chance of the infection spreading.

See DDS: See your dentist immediately to avoid any further complications. What is the history of the tooth, trauma? decay?
