I grind my teeth at night and have to have a mouth guard made by the dentist. I'm a bit of a wuss about the dentist as I have a very over-sensitive gag reflex - they eventually gave up trying to give me x-rays as I couldn't hold the thing in my mouth without gagging, even when they tried the chidren's one . I'm guessing having a mouthguard made is going to involve having stuff put in my mouth, can anyone tell me about it so I know what to expect?
