Causes of Sensitivity

Sensitivity is commonly caused when the gums recede and there is damage to the tooth's protective layer of enamel.

Although there are many contributing factors, the main causes of tooth sensitivity are:

Incorrect brushing
Brushing too often or too vigorously can wear away tooth enamel, exposing the underlying dentine. The dentine may also be exposed as a result of gum recession.

Stress
When suffering from daily stress, some people unfortunately grind their teeth unconsciously while asleep. This seriously wears the tooth enamel.

Acidic Diet
Acidic food and drink can cause erosion of tooth enamel, which is often exacerbated by over-enthusiastic tooth brushing. This can expose the underlying dentine which is sensitive to hot and cold. See the dental advice section for advice on diet.

Gum Disease
Gum disease begins when the bacteria in plaque causes the gums to become inflamed. It can affect one or more teeth at a time. With the mildest form of the disease, gingivitis, the gums redden and swell, and tend to bleed easily. It can be difficult to detect as there is usually little or no discomfort.

Gingivitis is reversible with professional treatment and good oral home care.
