Sensitive Teeth

When you have sensitive teeth, certain activities, such as brushing, eating and drinking, can cause sharp, temporary pain in your teeth. Sensitive teeth are typically the result of worn tooth enamel or exposed tooth roots. Sometimes, however, tooth discomfort is caused by other factors, such as a cavity, a cracked or chipped tooth, a worn filling, or gum disease.

Dentine hypersensitivity, or tooth sensitivity, is a common dental problem. It’s a condition that can develop over time, as a result of common problems such as receding gums and enamel wear. Most sufferers are between 20 and 50 years old. Tooth sensitivity can start to happen when the softer, inner part of the tooth called ‘dentine’ becomes exposed. Dentine lies under the enamel and the gums.

Thousands of microscopic channels run through the dentine towards the centre of the tooth. Once the dentine is exposed, external triggers (such as a cold drink) can stimulate the nerves inside the tooth, resulting in the characteristic short, sharp pain of tooth sensitivity.

Enamel Wear

Enamel is the hard outermost surface of the tooth. Although it's harder than any other substance in the body, over time it can gradually wear away causing teeth to appear yellow and dull. Enamel wear can also lead to tooth sensitivity.

Enamel wear can be caused by:

Tooth Grinding

Do you grind your teeth, either at night or during the day? If so, you may be wearing down the enamel, which over time can expose the underlying dentine.

Tooth Brushing

If you brush too frequently or too hard, eventually your tooth enamel may be worn away or you could develop receding gums.

To prevent this ask your dentist or hygienist for advice on the best tooth brushing technique and oral hygiene routine for you, and try using a soft-bristled toothbrush.

Acid Erosion

Over time, acidic foods and drinks can cause your tooth enamel to wear down - this is called acid erosion. Acidic foods and drinks include fruit and fruit juices, carbonated drinks, black coffee or tea, wine, and anything that tastes sharp such as ketchup or salad dressing. As few as four acidic 'challenges' throughout the day can put your enamel at risk from acid erosion, also known as acid wear.
