Why do we have sensitive teeth?

Commonly called “sensitive teeth,” hypersensitivity dentin is a common and usually, harmless symptom that occurs when the dentine (=  dental tissue) is reached. Brief, acute pain occurs when the teeth come into contact with hot or cold liquid, particularly sweet or acid foods, when brushing or flossing, or even breathing a breath of fresh air.

Healthy teeth are formed by four tissues: the cementum, the dentine, dental pulp, and enamel.

The enamel and gums protect the tooth agents agreements. However, poor hygiene Oral can cause some problems as the formation of microscopic holes that affect the dentine.

Dentin hypersensitivity may also be associated with:

  • Inflammation or gingival retraction: this condition is rather common since it reaches four people out of 5 before the age of 65 years. It is a retraction of the gums that leaves the root of the tooth uncovered.
  • Enamel erosion: acidic foods are the primary cause of enamel degradation. During brushing, enamel softened by acidity can drop, then expose the dentin of the tooth.
  • A bad technique of brushing teeth. Between 50% and 90% of people do not brush their teeth properly. They often rely too much on the tooth which in the long term can cause gingival retraction.Inadequate brushing can also cause plaque to turn into tartar which can lead to further complications. Finally, the use of a brush whose bristles are too stiff may cause abrasion of the tooth.
  • Wear caused by bruxism, i.e., the grinding between the teeth that occurs when there is no swallowing or chewing. Although it can happen at any time of the day, bruxism occurs more frequently during sleep.

Other causes may also cause dentin hypersensitivity:

  • An image for aesthetics
  • Broken teeth
  • Scaling
  • The formation of dental caries
