Causes and remedies for sensitive teeth

Written by: Dra. Marina Población Subiza

The sensation of pain in the teeth when noticing contact with very hot or cold substances is a direct consequence of the so-called dental sensitivity. This symptom appears when dentin is exposed to this type of external agents. Therefore, everything that decreases the layer of transparent enamel that protects the dentine or allows the area under the gum to be exposed, will be the cause of sensitivity in the teeth.  

The factors that decrease the enamel are : tooth decay , brushing very hard or with a very hard brush, dental fractures and bruxism. Enamel also affects tooth whitening , acidic foods and routine dental procedures. In addition, there are mouthwashes and toothpastes for sale that are nicknamed "natural" that damage the enamel.


And the factors that expose the root are the periodontal disease (the bone level is reduced), the occlusal traumas (they occur when the teeth are not aligned and the occlusion of the upper jaw with the lower one is not the correct one) and the age. This last factor causes the bony crests to be lost over time, retracting the gum and allowing the root to remain slightly open to the air.. This produces neck caries , which are responsible for the sensitivity of most people over 50 years.  

Treatment for dental sensitivity

Maintain good oral hygiene. Brushing is a "matter of strategy", no matter how hard you clean it better , you have to go through all the surfaces (teeth and grindstones) to eliminate all traces of bacterial plaque. In addition they must be cleaned orally by the professional. Dental products must be fluorinated and daily use of fluoride rinse may decrease sensitivity.
