Do you have sensitive teeth?

Tooth sensitivity is discomfort in one or more teeth that is triggered by hot, cold, sweet or sour foods and drinks, or even by breathing cold air. The pain can be sharp, sudden, and shoot deep into the nerve endings of your teeth.

What causes tooth sensitivity?

Tooth sensitivity occurs when the underlying layer of your teeth – the dentin – becomes exposed as a result of receding gum tissue (the protective blanket that covers the tooth roots). The roots, which are not covered by hard enamel, contain thousands of tiny tubules leading to the tooth’s nerve centre (the pulp). These dentinal tubules (or channels) allow the stimuli – for example, the hot, cold, or sweet food – to reach the nerve in your tooth, which results in the pain you feel.

There are many factors that may lead to tooth sensitivity, including:

  • Brushing too hard. Over time, brushing too hard or using a hard-bristled toothbrush can wear down enamel and cause the dentin to be exposed. It can also cause recession of the gums (the gum tissue pulls away from the teeth).
  • Recession of the gums. As gums move away from a tooth due to conditions such as periodontal disease, the root surface becomes exposed.
  • Gum disease (gingivitis). Inflamed and sore gum tissue may cause sensitivity due to the loss of supporting ligaments, which exposes the root surface that leads directly to the nerve of the tooth.
  • Cracked teeth. Chipped or broken teeth may fill with bacteria from plaque and enter the pulp causing inflammation.
  • Teeth grinding. Grinding or clenching your teeth may wear down the enamel and expose underlying dentin.
  • Tooth-whiteningproducts or toothpaste with baking soda and peroxide.These products are major contributors to teeth sensitivity.
  • Your age. Tooth sensitivity is greatest between the ages of 25 and 30.
  • Plaque build-up. The presence of plaque on the root surfaces can cause sensitivity.
  • Mouthwashes. Long-term use of some mouthwashes. Some over-the-counter mouthwashes contain acids that can worsen tooth sensitivity if you have exposed dentin (the middle layer of the tooth). The acids further damage the dentin layer of the tooth. If you have dentin sensitivity, ask your dentist about a neutral fluoride solution.
  • Acidic foods. Regular consumption of foods with a high acid content, such as citrus fruits, tomatoes, pickles and tea, can cause enamel erosion.
  • Recent routine dental procedures. Sensitivity can occur following teeth cleaning, root planing, crown placement, and tooth restoration. Sensitivity caused by dental procedures is temporary, usually disappearing in four to six weeks.

What can I do to reduce tooth sensitivity?

  • Maintain good oral hygiene. Continue to follow proper brushing and flossing techniques to thoroughly clean all parts of your teeth and mouth.
  • Use a soft bristled toothbrush. This will result in less toothbrush abrasion to the tooth surface and less irritation to your gums. Brush gently and carefully around the gum line so you do not remove more gum tissue.
  • Use desensitising toothpaste. There are several brands available for sensitive teeth. With regular use you should notice a decrease in sensitivity. You may need to try several different brands to find the product that works best for you. Another tip is to spread a thin layer of the toothpaste on the exposed tooth roots with your finger or a cotton bud before you go to bed. Do not use a tartar-control toothpaste; rather, use a fluoridated toothpaste.
  • Watch what you eat. Frequent consumption of highly acidic foods can gradually dissolve tooth enamel and lead to dentin exposure. Such foods may also aggravate the sensitivity and start the pain reaction.
  • Use fluoridated dental products. Daily use of a fluoridated mouth rinse can decrease sensitivity. Ask your dentist about available products.
  • Avoid teeth grinding. If you grind or clench your teeth, use a mouth guard at night.
  • See your dentist at regular intervals. Get professional tooth cleaning, oral hygiene instructions and fluoride treatments as often as advised.

If you still have discomfort, talk to your dentist. There may be some dental procedures that may help reduce sensitivity, including the use of:

  • White fillings (bonding) to cover exposed root surfaces
  • Fluoride varnishes applied to the exposed root surface
  • Dentin sealers applied to the exposed root surface
