Tooth sensitivity is caused by the movement of the fluid inside the tubes found in the tissue beneath the enamel of the tooth called the dentin. If the enamel on the tooth has become too thin or the patient has receded or receding gums, the tubes become exposed, which leads to nerve irritation and results in sensitivity to cold, heat and touching. There are many causes that can determine enamel thinning and gum recession – here are some:
- A toothbrush that is too hard or brushing movements that are too vigorous can lead to the thinning of the enamel and increase the sensitivity of the dentin.
- The erosion of the surface of the tooth caused by acidic beverages and food combined with poor oral hygiene also lead to increased sensitivity.
- Decayed tooth or tooth fillings that are leaking also expose the dentin.
- Teeth grinding and clenching that damage the surface of the tooth also lead to the exposure of the deeper layers of the teeth, causing pain in the jaws and sensitivity in the teeth.
There are two common treatment options for dental sensitivity: a Centennial dental office can apply fluoridegel to strengthen the enamel instantly or you can start using an over-the-counter, desensitizing toothpaste that apply a protective layer on the nerve in the dentin.
