That's a lip tie. My son has it too. He only has 4 top teeth so far so he has a gap. I had problems breastfeeding too. My son kept losing his latch.

My sister had one and had removed when she was 28. It was like gum overgrowth on front teeth and caused a minor gap. Quick and easy procedure.

My son had a tongue tie that was clipped in the hospital because he was having trouble latching. He still wouldn't latch a month later and I discovered he had a lip tie too. By that point I was already exclusively pumping so I was just like fxck it. Haha - looks like a lip tie to me.

My dad is a dentist and he says lip ties are no concern to ur teeth. Apparently some dentists will tell u so: which just results in them making money out of u to cut it!! Goodluck

My niece had this and still does 4th grade. Her teeth look perfect, no gaps.

I must have gotten lucky. My dd doesn't have a gap, yet. I'm sorry ladies :-(

My baby has this...she also has quite a gap between her teeth

It will make a huge gap between her two front teeth, that is fire sure why she had latch problems.

Yes it is. My dd is 16 mo old and has the same. Her dentist says that it shouldn't affect her teeth, but there is always a possibility. It might break on its own, if so there will be a lot of blood. If it doesn't the dentist can do a quick outpatient laser surgery.

Is it a cause for concern with his teeth now that hes getting older?

Yes that is defs lip tie
