tooth sensitivity


Tooth sensitivity is a common problem that affects many people around the world. It is characterised by a painful or uncomfortable sensation in the teeth. It is very important to know what causes it and what treatments are available to prevent and combat this ailment.


Dentine sensitivity., also known as dental hypersensitivity, is a condition in which the teeth experience a sharp pain or discomfort when exposed to certain stimuli such as cold, hot, sweet or acidic foods, as well as tooth brushing. This unpleasant sensation is caused by exposure of the dentine, the inner layer of the tooth filled with millions of microscopic tubules. When exposed, these external stimuli can reach the dental pulp, where the nerve is located, causing the pain.


There are several causes of dentine sensitivity. One of the most common is gum recession, which is when the gums recede, i.e. pull away from the tooth, the dentine, which is normally protected, is exposed. This can occur due to gum disease, aggressive tooth brushing or bruxism, which is when a person grinds, clenches or even gnashes their own teeth.

Another cause is tooth enamel wear. Tooth enamel is the hard outer layer that protects the teeth. If this is worn away, due to poor oral hygiene, excessive consumption of acidic foods or grinding of the teeth, the dentine will be exposed and cause sensitivity.

Tooth decay also causes tooth sensitivity. Tooth decay is a hole in the tooth caused by the complete breakdown of enamel. When a cavity goes deeper into the tooth and reaches the dentin, tooth sensitivity occurs.

Finally, some dental treatments, such as teeth cleaning, teeth whitening, or the placement of fillings, can cause temporary tooth sensitivity.


Fortunately for those who suffer from tooth sensitivity, there are several treatments available to alleviate this unpleasant sensation. Some options to combat it are:

  • Use of desensitising toothpaste: this type of toothpaste contains special compounds that help block the dentine tubules, thereby reducing sensitivity.
    Application of fluoride varnish: the dentist applies this liquid to the teeth which helps to strengthen the tooth enamel, thus reducing tooth sensitivity.
  • Dental sealants: these are resins that are applied to the chewing surfaces of the teeth to protect the enamel and prevent sensitivity.
  • Modification of brushing habits: brushing with a gentle technique and using brushes with softer bristles can help prevent tooth sensitivity caused by aggressive brushing.
  • Dental treatment: In more severe cases of tooth sensitivity caused by exposed dental pulp, it may be necessary to remove the nerve through periodontal surgery and, to a lesser extent, root scaling to remove the plaque that causes tooth sensitivity.
