Teeth sensitivity is the discomfort felt when chewing or drinking hot or cold beverages.

According to studies, 15 to 57% of the population suffers from dental sensitivity, also called dentin hypersensitivity. This sensitivity is often caused by thermal or mechanical stimulation such as teeth brushing.

It is described as a pain resembling an electric shock.

Causes of dental sensitivity:

The dentin is the part of the tooth that is beneath the enamel. It contains microscopic tubules.

When the dentin loses its protective covering (enamel), the tubules allow heat and cold or acidic or sticky foods to stimulate the nerves and cells inside the tooth, causing sensitivity.

This is also the case for receding gums.

Enamel loss: can be caused by teeth grinding, acidic food, aggressive and/or frequent brushing of the teeth, or frequent vomiting.

Gingival recession: can be caused by gum disease or a vigorous brushing of the teeth. 

Dental sensitivity triggers:

1.Cold food or beverages.

2.Hot food or beverages.

3.Sweet or sour food.

4.Inhaling air.

5.Teeth brushing.

Teeth sensitivity is often confused with similar dental pain.

This pain is manifested in different situations:

*Cavities: The acids produced by the bacteria dissolve the enamel, creating holes called cavities.

*Teeth whitening: Many people complain of teeth sensitivity during and after teeth whitening sessions.

This is the result of the whitening component entering the pulp chamber and causing inflammation. Teeth sensitivity, in this case, is temporary.

*Dental treatment: It is possible to feel sensitivity after dental care. However, if it persists, it is necessary to consult your dentist.

*Cracked or chipped tooth.

Teeth sensitivity treatment:

When your dentist determines the cause of dental sensitivity, a treatment plan can be established.

1.Oral hygiene: 

Patients with sensitivity usually abstain from brushing their teeth, which exacerbates the problem.

The first step is brushing your teeth properly.

2.The right toothpaste:

 It is necessary to choose a toothpaste adapted to sensitive teeth. Sensodyne has proven to be quite effective in relieving sensitivity in the long term.

3.The right toothbrush:

In some cases, a toothbrush with soft bristles is necessary to reduce dentin hypersensitivity.

4.Oral hygiene adjuvants:

Your dentist can prescribe you a mouthwash, fluoride gel, fluoride varnish, …

5.Dental treatment:

If dental sensitivity is the result of enamel loss, the restoration of the affected teeth is essential.

6.Periodontal treatment:

In the case of periodontal disease, a thorough treatment is necessary to restore a healthy periodontium that effectively protects the teeth.


Dental sensitivity is usually the result of bad habits. Discarding these habits is the best solution to prevent teeth sensitivity.

When dealing with sensitivity or any dental pain in general, it is best to consult your dentist.
