I have painless lump on gums and a slightly loose tooth, no pain though, any ideas?

Draining abscess: Your have a draining tooth pulpal absess. Because it is draining, the abscess does not compress on the nerve and thus explain for the painless symptom. The low fluid retention explains for the slight mobility. The tooth is pulpal necrosis, or dead, and developing and abscess. The draining from the abscess is termed fistula, with the open end on the gum.

Some thoughts...: A loose tooth usually is indicative of a periodontal problem. Throw in the "lump" and abscess comes to mind. It may be related to your gums or your tooth, hard to tell over the internet. It needs to be treated by a local dentist. You know you need to make a call.. Do it before there's an emergency.

Developing infection: That loose tooth is probably loose due to infection, and an abscess is forming that's the lump on your gums. See a dentist asap to have it checked and treated.

See your dentist: A chronic dental abscess may produce no pain with intermittent swelling, but can develop into an acute abscess at any point. The goal of any treatment is to remove the infection, save the tooth , and prevent further complications. see your dentist for evaluation and x-rays.
