Chuck out your toothbrush and pick up one with soft bristles. Brush twice a day with desensitizing toothpaste and take care to gently clean along the gumline. Floss and rinse with a fluoridated mouthwash. Avoid acidic and sweet foods and drinks like coffee, soda, wine, and fruit juice especially before bed. If you catch yourself clenching or grinding your teeth, try practicing mindfulness or other relaxation techniques to give your jaw a break. To stop sensitive teeth pain for good, you will have to see the dentist so we can determine the underlying cause once and for all.
