Ask your dentist: Do you have a specific concern? This is a question best answered by your dentist who can examine you, check with an x-ray if necessary and let you know if any other treatment is necessary.

Itchy?: Hard to know what that means. Dentist's understand pain and discomfort. If you are having a problem, you should see your dentist and possibly they can examine and figure out exactly what is bothering you.
