Q. i have a dead front tooth, it is very discoloured, i had a brace when i was young but didn’t wear the retainer properly, so my front teeth are wonky again, i want another brace and also want internal bleeching, my dentist has reffered my to a root canal specialist for the whitening, but says i cannot have a brace as it may cause me to loose my dead tooth, but i cant live with it any more, i hate it, what can i do??,
