I grind my teeth at night and now wear a night guard which helps a lot. I also catch myself clenching my teeth during the day and whenever I notice that I'm doing that I take a minute to relax my jaw. I can't really wear the mouth guard during the day as it make it difficult to talk. The mouth guard I use came from the dentist and it was costly and not covered by insurance, but it is helping to save my teeth from further damage. Good luck to you.
