Tooth Sensitivity: Frequently Asked Questions

Tooth sensitivity is usually a sharp pain in response to cold air or food or drinks that are especially hot or cold or very sweet or sour³⁸. If you’re experiencing pain that is more severe and more constant, chances are it’s a different kind of mouth pain.

Sensitive gums can actually be a cause of sensitive teeth. As the gums pull back, dentin becomes exposed and your teeth become less protected from sensations like hot and cold. While sensitive teeth don’t necessarily look that different, sensitive gums will turn red and may bleed. Unlike sensitive teeth, sensitive gums may not hurt that much at all. But the longer you ignore them, the worse for your teeth, so see your dentist as soon as possible.

Tooth sensitivity can be a sign of enamel erosion as the bacteria eats away at the tooth’s surface. However, it’s always best to visit the dentist for a professional check up³⁸.
