My daughter who is 8 years old have tongue thrust and open bite. She was doing some excercises which was refereed by a orthodontists. Now she has a minimal of open bite problem but the tongue thrusting is there. She had a toungue thrusting appliances which is removable few days before. Today I observed that she is still having her tongue out between the front teeth while she is sleeping (but her mouth is always closed; when we open the mouth, we could see the tongue between the front teeth). I am concerned now; is it normal to still have the tongue out when the kids have the removable tongue thrust appliances. Pls advice.
