Pretty sure it is from anxiety. I chipped a tooth the other night from grinding my teeth.
oh that’s definitely not good, bud. ouch.
Have you tried Hyoscyamine? That’s the generic, don’t know the brand name in the UK. It slows the intestines and helps control IBS, it’s been a miracle for me. About your teeth, have you tried a bite guard? They make cheap ones you can buy at the pharmacy.
