Dental Sensitivity

Dental sensitivity affects a large number of people. It is generally triggered by hot, cold, sweet, or acidic foods and drinks. Under normal conditions, the dentin (the inner layer of the tooth) is covered by enamel and gums around the tooth. Over time, the enamel can wear down and the gums may recede, exposing the root of the tooth.

The dentin has a large number of microscopic pores (tubules) that extend from the outer surface of the tooth to the pulp at the center. When the dentin is exposed, the fluids within these tubules can be stimulated by temperature changes or certain foods, causing sensitivity. This exposure of the dentin can occur due to several factors, such as gum recession, acidic drinks (like sodas), bruxism, intense brushing, the use of abrasive toothpaste, fractured and/or decayed teeth.

Teeth whitening, orthodontic appliances, or deep restorations are also examples of causes for dental sensitivity. However, this symptom is usually temporary.

To eliminate or reduce this symptom, various procedures can be performed, either in-office or on an outpatient basis, depending on the cause. A consultation with a dentist is therefore essential. It may be necessary to adjust your brushing technique, use soft-bristled toothbrushes, and use a toothpaste designed to reduce sensitivity. In the office, we can also apply fluoride varnishes, perform restorations in areas where enamel has been lost, among other solutions… The most important step is to consult your dentist to determine the cause of the dental sensitivity and find the most suitable solution for each case.
