How long does it take for lip swelling to go down?

Depends: It depends on why it is swollen. You have to know the cause before we can talk recovery.

Varies: Selling of the lip may be of different origins. Infectious swelling will gradually begin to subside as the infection recedes, while traumatic swelling will subside according to the severity of the trauma. I would be best for you to see your md or dentist to identify the cause of the swelling and advise you accordingly. Good luck -.
