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

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. Keep sensitivity at bay with the right oral care. Brush and rinse twice daily and floss once a day. Also, avoid grinding and hard-brushing your teeth as it wears them down and may lead to tooth sensitivity.

Cavities can definitely cause tooth sensitivity as the germs eats away at the tooth’s enamel. But there are plenty of other causes of sensitive teeth, including:

• Brushing too hard

• Gum problems

• Cracks in enamel

• Teeth grinding

• Whitening treatments
