Sensitive Teeth

Overview:

Sensitive teeth (dental hypersensitivity) is a common problem affecting millions of people worldwide. It can lead to an intense, shooting pain when eating or drinking hot, cold or acidic foods or breathing in cold air.

Dentine is found underneath the protective enamel coating on the crown & cementum on the root. It contains a large number of tubules which run from the surface of the tooth to the inner nerves. When enamel/cementum is worn away, dentine is exposed, leading to pain & sensitivity.

Sensitive teeth can affect people of any age, but it is seen most often in people between the ages of 30 and 40.

What causes sensitive teeth?

• Over zealous brushing & or using a brush with hard bristles are common causes of sensitive teeth. Not only can this wear away the enamel but it can also cause the gums to recede.

• Gum disease also causes the gums to recede.

• Teeth whitening products.

• Acidic foods and drinks can cause tooth erosion & dissolve the tooth surface.

• Damaged teeth. Either cracks in teeth or teeth grinding can damage the tooth surface, exposing the dentine, leading to sensitivity.

• Tooth cavities.
