If its causing latching issues I would get her seen, if not its not a big concern and if down the road if effects their teeth they will fix it. My son has this and his teeth look fine, no gap and no latch issues. Tongue ties are more of a problem.
Yes, my sons looked like this. It didn’t stop him from latching & his doctor said it’s fine so I didn’t do anything about it. He has a gap now though but it’s very cute.
