I grind my teeth at night and have been breaking my retainers. what are other solutions to my problem?

Stress relief: Most people grind from stress gained during the day. The best stress relief is 30 min of moderate exercise;chk with your MD to be sure this is for you. Other ways to reduce stress are to meditate/get your mind quiet for 30-60 min /day. For the retainers try a well made night guard so see your dentist. This will act as an upper retainer while protecting your teeth from damage.
