<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello, Im writing because a year ago I had all 4 of my wisdom teeth taken out because they were impacted and causing me pain. A couple months after the fact, a small solid but painless bump appeared on the outside of my gums by the upper left extraction site. As recently as a month ago, the bump seemed to be more sensitive and a tiny pointed bone like protrusion seemed to work its way through the soft tissue. That has since healed over and isnt nearly as swollen, however now the upper right side seems to be starting to swell. Anything you can tell me to help would be appreciated.  <response>: Hello:Welcome to Chat Doctor. This can be a bony protrusion from the extraction socket. Nothing to worry. See your dentist once. He will remove it. Do not worry, it is as easy as you remove debris from your teeth.Its not a painful procedure. The sharp bone can project out some times during healing and irritate the surrounding cheek and soft tissue. Take a OTC painkiller if necessary. Apply qua Chat Doctor. Regards.
