Why do I experience sharp pains when eating or drinking hot foods or drinks?
Teeth are naturally protected by enamel, the hardest substance in the body. It is supported by a softer substance called dentin, which extends to form the roots of the teeth. The nerve of the tooth resides in the porous dentin. Exposed dentin allows stimuli such as hot and cold drinks, ice cream, sweet and sour foods and even the touch of a toothbrush to trigger the pain. Sensitive teeth can be caused by poor brushing techniques. If you use a hard toothbrush, or do not brush your teeth correctly, you can wear away protective tooth enamel and expose dentin. Incorrect brushing techniques or gum disease can also cause gums to recede or pull back, exposing the roots of the teeth. Once this area is exposed, the chance of sensitivity is greatly increased.
