<s>[INST] My daughter bit the inside of her lower lip really bad the other day after after having a filling at the dentist.  her mouth was still numb and she didn't realize the damage she was causing.  today is day 2 and there is a white/yellow coating over it.  should i remove the coating or keep it intact.  i just want it to heal as quick as possible.  i have been having her rinse with the colgate mouthwash with the hydrogen peroxide and have been applying ambesol to the actual sore.  the sore is the size of a quarter.   Thank you for your help.
