It is estimated that around 70-80 percent of people will experience pain caused by tooth sensitivity in their lifetime.

What causes sensitivity?

Tooth sensitivity is caused by the dentin portion of the tooth becoming exposed, which happens when the enamel surfaces of the teeth are worn or damaged. The dentin portion of the tooth contains the pulp, which is the living tissue of the teeth and contains blood vessels and nerves. When the nerves are exposed, this causes pain, especially when you drink or eat very hot or very cold foods.

Coping with sensitivity

Once the enamel surface of the tooth is worn, it is impossible to replace or repair it, as enamel is not living tissue and the body cannot regenerate it. One of the most effective ways of coping with sensitivity is using specialist oral hygiene products, which help to preserve and strengthen the enamel, decreasing the pain associated with sensitivity. There are many different oral hygiene products available that been specially developed for people who suffer from sensitive teeth. Some are designed to prevent sensitivity in the long-term, while others provide rapid relief for pain caused by sensitivity.
Avoiding triggers is also a means of reducing sensitivity – most people find that hot and cold foods, such as ice cold drinks, ice creams and hot coffee trigger pain.

Preventing sensitivity

The only way to prevent sensitivity is to preserve and protect the enamel. You can do this by adopting a good oral hygiene routine and visiting your dentist for regular dental check-ups. Diet is also important because acidic foods and drinks and those that are high in sugar can contribute to acid erosion.
