A sharp twinge when you sip something cold or bite into something sweet is a common complaint. Tooth sensitivity often develops when enamel wears thin or gums recede, exposing a softer layer beneath called dentin.
Brushing too hard, frequent acidic foods and drinks, and teeth grinding can all contribute. Cavities, worn fillings and cracked teeth can cause similar pain, so a lasting problem should be checked rather than guessed at.
- Use a soft toothbrush and light pressure.
- Try a toothpaste made for sensitive teeth and use it consistently.
- Limit soda, citrus and other acidic drinks, and avoid sipping them all day.
See your dentist if sensitivity lasts more than a few weeks, affects just one tooth, or comes with swelling or constant pain.
