Any advice for a split upper lip tie? Not diagnosed but I believe my 13 month old has/had a lip tie as the skin joined and she had a bad between her top teeth where it went through too.

Luckily it never affected us with breastfeeding however I noticed today that it's torn and is a little bloody. Is there anything I can do to,keep any infections away? Is it open or she's okay to eat and stuff x
