Gum receding around bottom incisor tooth, what to do?

Peridontist: See a periodontist for an evaluation. Cause should be determined, further recession prevented and treatment for severe cases.

Disease or position: Two major causes of gum recession around lower anterior teeth are gum disease or teeth positioned off of their bone support and therefore undergoing untoward stress (or a combination of the two). You may need to see periodontist, orthodontist, or both. See your dentist for evaluation and possible referrals.

Gum recession !!: Gum recession is not a normal phenomenon! gum recession is a sign that something is amiss. Either clenching or grinding as a parafunctional habit, improper homecare, etc are the main reasons these things develop. There can be other secondary reasons like high muscle attachments, but rule out the obvious is a good first line of attack.
