What Causes Sensitive Teeth?
It mostly happens when your gums pull back and expose the tooth surface beneath, called the dentin. This soft layer makes up the inner part and roots, which have thousands of tiny tubes that lead to tooth’s nerve center called Pulp.
Other things that can cause teeth sensitivity are:
1. Wear and tear. Over time, brushing too hard or using a hard-bristled tooth-brushes and over grinding of teeth during mastication can wear down enamel and expose the dentin.
2. Tooth decay (caries), broken/chipped teeth and certain dental treatment procedures like crown cutting and cavity cutting can cause sensitivity.
3. Gum diseases which pull back and expose the roots of your teeth can cause sensitivity.
4. Teeth-whitening (bleaching) products can be contributors to sensitive teeth.
5. Food and drinks with a high acid content, like citrus fruits, tomatoes, pickles, and tea, can wear down enamel and make teeth sensitive.
