What Is Tooth Sensitivity?

Tooth sensitivity is a common problem. If you feel a twinge of pain when eating hot or cold foods, brushing or flossing, or even breathing cold air, you may have sensitive teeth. Read on to find out more about tooth sensitivity and its causes.

What causes tooth sensitivity?

Your teeth may hurt for a number of reasons, from cavities to gum disease. However, the characteristic twinge of sensitivity pain is different. Teeth are covered by a hard layer of minerals known as enamel. When enamel wears away, it leaves the soft inner layer—called dentin—exposed. This allows outside triggers to reach the nerves and causes the sharp pain known as tooth sensitivity.

Who gets sensitive teeth?

Tooth sensitivity can occur at any age, but surprisingly, it’s most common between the ages of 20–50. Sensitive teeth are not a sign of poor oral hygiene. In fact, brushing too vigorously can actually wear away enamel, leading to sensitivity. Acidic foods, receding gums, and even acid reflux can all contribute to this process.

Can tooth sensitivity be treated?

Tooth sensitivity can be easily treated at home by using a desensitizing toothpaste like Sensodyne®. With a range of products designed to either numb the nerves or form a protective layer over them, Sensodyne works to help prevent sensitivity triggers from irritating teeth. In more persistent cases, your dentist may recommend in-office treatments.
