Gilly I'm sorry to hear you are in pain, lemme suggest something that the dentist told me about when my kids were grinding their teeth (so loud at night they woke me up, which is pretty hard grinding), go to a department store to the sports section and get a mouth guard that football players, wrestlers, etc wear. It's plastic and just a couple of dollars. Cut the part off that hooks to a helmet of course. Get a pot of water boiling and dip, very quickly, this mouthpiece in the hot water to soften it up then put it in your mouth and bite down. This will adjust it to fit your mouth. Wearing this when you sleep might help and is a lot cheaper than a mouthguard from the dentist. Hope this helps.
