My DD is almost 10 and is still sucking her thumb. I have tried all sorts of things to stop her but nothing so far has worked.
Been to the dentist today who informed her (again) that she should stop sucking her thumb and that she will need braces in the next couple of years as she has a hole in the middle of her teeth when she closes them (open bite). No surprise there.
But then he said that he didn't think this alone would work and she may need her jaws realigned.
Just googled and it seems that jaw surgery may be required for an open bite. It seems like a very scary operation.
AIBU to feel like I should have done a lot more.... not sure what...but more.
