My dd has a horrendous ulscer which is rubbing directly on her brace. She hasn't gone to school today cos she can't speak or eat without it rubbing and is having to hold her lip away from it to get any relief. The dental wax from dentist is, she says , just sliding off her brace so no help. Can anyone recommend a descent wax or silicon that stays in place and also what's the best ulscer medication....bonjela isn't helping. I need her back in school tomorrow! Thanks.
