The two main causes of sensitive teeth are brushing your teeth with too much force and consuming acidic food and beverages according to a nationwide survey of dentists. The sensitivity is caused by nerve irritation.

Tooth sensitivity is a sharp pain and discomfort in one or more teeth. It is often triggered by hot or cold food or drinks, breathing cold air, or pressure on the teeth. 40 million Americans suffer from sensitive teeth.

The forceful brushing and consumption of acidic substances wears down the enamel and also affects causes the gums to recede. This leaves the softer tissue in the teeth, dentin exposed. Since dentin is connected to the nerve center of the tooth, this leaves people vulnerable to sensations of pain.

Other factors that can cause tooth sensitivity include certain toothpastes, mouthwashes, tooth whiteners, breaks or cracks in the teeth, bulimia and acid reflux.

Things you can do to prevent tooth sensitivity include:

-using a desensitizing toothpaste

-using a soft bristled toothbrush

-flossing daily and brushing twice a day for two to three minutes

-holding the tooth brush at a 45 degree angle, using a gentle circular motion and holding it in your fingertips

-avoiding acidic foods and drinks, ie. pop and citrus foods
