Causes of Sensitive Teeth

by Haddon Suttner

Tooth sensitivity is caused by the gradual exposure of the softer part of your tooth that lies under the tooth enamel, called “dentine”.Dentine has tiny tubes (‘tubules’) that lead to the nerve and are filled with fluid. Eating or drinking foods and drinks that are hot, cold or sweet can cause a change in fluid movement. This fluid movement causes the nerve endings to react in response, triggering a short, sharp pain.

Common Causes of Sensitive Teeth

Brushing

Brushing shortly after acid challenge can cause the enamel to be more easily worn away, as during this time the enamel is softened and more vulnerable. Brushing can also cause receding gums, causing further exposure of the dentine.

Gum Disease

Gum disease (also known as gingivitis) causes inflamed and sore gum tissue.  If left untreated, gingivitis can lead to periodontitis. Periodontitis is when gum disease gets worse and damages the tissues and bone that support the teeth. One symptom of periodontitis is sensitive teeth, as the receding gums leave dentine exposed.

Teeth Grinding

If you grind your teeth when you sleep or during the day, or if you clench your teeth, you may be wearing down enamel and exposing the underlying dentine layer of your tooth.

Receding Gums

Receding gums can be caused by conditions such as gum disease, which can expose the tooth’s dentine and cause sensitivity. Brushing too vigorously can also cause receding gums.
