If you occasionally experience a sudden flash of pain, or a mild tingly feeling when you bite into sweet or sour foods, or drink hot or cold beverages, you may have sensitive teeth.
Causes and Development
In healthy teeth, porous tissue called dentin is protected by your gums and your teeth's hard enamel shell. When this protection is lost, microscopic holes in the dentin called tubules, allow heat, cold and other irritants to be transmitted back to the tooth nerve triggering pain. Dentin can be exposed by:
- Receding gums caused by improper brushing or gum disease
- Fractured or chipped teeth
- Clenching or grinding your teeth (Bruxism).
Signs and Symptoms
Pain from sensitive teeth is not always constant; it can come and go. Constant pain could be a sign of a more serious problem. It is still important, however, to discuss your symptoms with your dentist to determine the cause and proper treatment.
