5. Put a stop to tooth grinding
If you’re grinding your teeth when you’re tense, you could be wearing away enamel and giving yourself a sensitivity problem. You may not even realize you’re grinding: Often people only do it while they’re sleeping, but unexplained jaw pain or headaches could be a clue. If you do grind your teeth, try a mouth guard at night, or change your sleeping position. If you notice yourself clenching during the day, remind yourself to relax your jaw with your teeth slightly apart.
