When I was in around 6-7 years old, I had a fall, wherein a loose upper teeth fell and got pierced in the lower lip. Things were fine so far. But gradually now the lip volume on that particular spot where tooth pierced my lower lip is more and and on Vermillion border it feels like some knot kind of. It is not painful. But has caused lower lip asymmetry. It feels like there's something that pulls my lip down very strongly and it's a very unpleasant feeling. (If it's a cosmetic procedure like filler Botox. How much do they cost)?
