DENTAL SENSITIVITY

The Dentin Hypersensitivity (HD) or Dental Sensitivity is defined as an intense and transient dental pain caused by the exposure of dentin inside the tooth, the oral medium that appears after contact with an external stimulus: food and cold drinks, hot, sour, sweet; Touch pressure, etc…

It is the most common cause of dental pain and shows a high prevalence, affecting about 1 in 7 adults  and can trigger the onset of oral diseases such as caries, gingivitis or periodontitis, if not treated properly.

It usually occurs between 18 and 40 years old, and in recent years has increased in young patients by excessive consumption of beverages acid genic and indiscriminate use of tooth whitening products without supervision.

ORIGIN

Tooth sensitivity occurs when the dentin, which is protected by the gums, cemented and dentin, loses its natural protection and is exposed.

Dentin contains thousands of microscopic tubes, called dentinal tubules, which connect the outside of the tooth with the nerve endings. When the tooth loses its protection due to gum recession and / or wear of the tooth enamel, these tubules are open to the outside, allowing external stimuli reach the nerve endings and cause the pain sensation.
