If you're experiencing tooth sensitivity, you can try using toothpaste specifically designed for sensitive teeth. Rub a small amount of toothpaste into the sensitive area before bed, as it helps protect the surface overnight.
Additionally, try to avoid acidic foods and drinks, as they can aggravate sensitivity. Teeth grinding can also contribute to sensitivity, so consider using a mouthguard to help protect your teeth.
If the pain becomes severe or persistent, be sure to speak to your dentist for professional advice and treatment.
