Using Too Much Mouthwash
Love keeping your breath minty fresh? If you grab frequent swigs of mouthwash throughout the day, you may be setting yourself up for sensitive teeth
Eating Acidic Foods
Can't get enough tomatoes, citrus, fruit juices, cold drinks and other acidic goodies? Your teeth can. Enjoy too many acid-rich foods and drinks and you could erode the protective enamel on your teeth, exposing the vulnerable dentin beneath
The roots of your teeth contain thousands of tiny tubes that lead to the nerve center of your teeth. Usually teeth roots are hidden under a protective cover of gum tissue. But if you have periodontal disease, the gums may start pulling away from teeth, exposing the ultra-sensitive root.
Brushing Your Teeth Too Hard
Think brushing your teeth harder cleans them better? Think again. Brushing too strenuously (or using a hard-bristled brush) can expose tooth roots by causing gum recession. It can also wear away your tooth's enamel and expose dentin
Grinding or Clenching Your Teeth
Tooth enamel is the strongest material in your body, but it's no match for the power of clenching or grinding. Over time, both of these often-unconscious habits can wear away tooth enamel, leaving your teeth's nerves more vulnerable.
Decay, like this cavity, exposes the root of your tooth to a whole host of irritants: hot, cold, sweets, even air.
