I am 55 years old and I have gum recession in a posterior tooth. Can I cover it with crown?

The crown will feel big to your tongue and cheek because you haven't had a tooth there for a while. It takes about 2 weeks for your muscles to get adjusted to having a tooth there. If it still bothers you then the dentist can reshape the crown with a bur to make it more...

Hi:This could be part of a normal healing, however, its best to go back to your dentist and have the extraction site reevaluated.Best,Dr. Maddahi

Hi and thank you for your question. The first step would be to adjust the bite and have new Xrays taken. Best of luck!

Hi, You should go see your dentist immediately to see if they can still save the tooth and what the underlying issue is. 

There is a temporary cement  you can buy at the drug store. Clean out the hole and make sure there's no food impacted then place the temporary cement on top. It's important to seal the tooth so the root canal doesn't fail. If you can't afford the crown right now, have the general dentist...

It’s difficult to tell, but it may be an abscess. The tooth may be infected. Need to have that fixed (if possible), but you may end up loosing the molar. Either way, make an appointment to see a dentist ASAP before it gets worse.
