What causes tooth sensitivity?

0 Flares 0 Flares ×

Do you have sensitive teeth?

Normally, the enamel on our teeth covers the underlying dentine layer that surrounds the nerve. Sometimes this layer of hard enamel can wear and erode reducing its protection of the dentine, which in turn can cause increased sensitivity.

The erosion of enamel and dentine exposure can be caused by a number of factors including: –

  • Acidic beverages, such as fizzy drinks or juice
  • Tooth grinding
  • Brushing incorrectly and brushing more than three times a day

Sensitive teeth can also be attributed to gum recession caused by disease, old age or improper brushing or a chipped or broken tooth that exposes the dentine.

How can you prevent sensitivity?

In order to take action against tooth sensitivity, it is important to first find out the cause. If the sensitivity is due to exposed dentine you can use a very soft bristle toothbrush, ensure you are brushing correctly and use toothpaste specially formulated to reduce sensitivity.

Changing your diet can also help combat tooth sensitivity by removing particularly acidic foods, which can cause enamel erosion.

Your dentist can apply a fluoride varnish on the sensitive areas to help strengthen the tooth, provide high fluoride toothpaste for everyday use and place a dental restoration to build up the areas that have lost enamel.

Whether you need over the counter products or a dental procedure to combat tooth sensitivity, the most important step is to visit us at Smile Dental Clinics so one of our dentists can determine the cause of your tooth sensitivity and help find the right solution.
