[|Human|] I have a small hard lump in my mouth at the jawline on bottom left side.  I have a crown on the tooth that the small hard lump is under.  About 2 months ago I had a filling done on the tooth in front of the crown.  I will tell you she gave ma alot of shots to stop the pain (about 5)  She said at the time "I have given you enough for an elephant".  Well now I am nervious because, it has a lump under that area.  It is a bit sore, not horrible but noticeable.  What do you think it is
[|AI|]  Hello There, Painful hard lump under the tooth in which you had pain and infection indicates infection still persist in the same. So I would like to suggest you visit back to your dentist as soon as possible and get the thorough clinical examination done and x-ray of the same tooth for confirm diagnosis and take a proper treatment accordingly.Meanwhile, you can perform warm saline gargles 3-4 times a day. Nothing to get worried. Take Care. Chat Doctor.
