Casting newbie here. To keep from grinding my teeth at night I wear a custom molded mouth guard when I sleep. It was cast by my dentists about five years a go and is getting kind of grundgy even though I wash it every day. It hasn't noticeably worn. Rather than pay the dentist for a new one I thought I'd try casting my own from the current one. Can anyone recommend an appropriate resin for use in my mouth? I'm assuming any silicone mold material will work, but if that's wrong, please advise.
Thanks!
