I got a piece of sunflower seed stuck in my gum behind my front tooth. it was a few months ago. the gum area in front is still swollen?

See dentist ASAP: Go to the dentist. The duration of time is too long. Perhaps there was an existing periodontal pocket in the area and the material has migrated downward. Seeing your dentist would alleviate your problem and make sure it doesn't get worse.

Simple Solution: If you suspect something is caught in or around your tooth call your dentist and treat the problem before it becomes a major complication. If left untreated it can lead to severe pain, irreversible bone loss and even tooth loss.
