I feel at least 4 months ago. I hit my Lower mouth ,  under the gumline . five teeth back from the middle, right under I have a huge lump. You cant tell just by looking at me. It dose not hurt. My tounge does not recognize the difference. But when I push on my jaw I feel it. Like the size of a marble from the outside. But from the inside, it feels like half of a quarter size oval marble.how can I get rid of this.
HI. Any swelling remaining after 4 months may need excision, I suppose, if the medical management fails to resolve this. I would advise you to visit an Oral Surgeon or an ENT surgeon to get this examined and decide the course of action. Just follow his advice. This is important as this lump can give complications later. If it has to resolve on its own, would have been done within 3 weeks of injury-now it is 4 months, you say.
