His over bite is about 11 mm, he can't swallow properly because his lips don't meet and he's scarring his bottom lip because his upper teeth rest on it.
In the past we have tried
Stop and Grow, the nasty lotion you put on the nails,
A finger guard
positive reinforcement
bribery
tape
gloves
It's mainly at night but sometimes when he's watching TV etc.
We've just been to the dentist and she is warning us that he needs to break the habit asap. DS wants to stop and says he will but he's said that before. Can anyone recommend anything else that we can try to help him?
TIA
