Let's see if this works... Here's ds, you can sort of see the frenulum in the picture. He never had anything remotely resembling latch issues either. He's also got tight frenulae(?) on the sides, like right where the molars would start. I didn't even realize there WERE frenulae there. And yeah, mild sacral dimple, too.
Upper or lower molars? Where do they attach? Is that almost where dimples are?
And now, of course, I need to ask my kids to pull out their upper lips--I never considered that being tight on either kid. DD has a really thick frenulum between her top front teeth but I haven't seen issues from it other than the dental crowding it's causing.
PB--how does the frenulum being tight in front cause cavities on the back of the teeth? And... how can you tell that's tight? Theloose--is that as far as your DS's lip will comfortably move away from his teeth?
