Tooth sensitivity: what it is, symptoms and treatment

Tooth sensitivity can be an uncomfortable experience that affects quality of life. It occurs when the dentine, the layer beneath the tooth enamel and gum, becomes exposed.

What is tooth sensitivity?

Tooth sensitivity, also known as dentine hypersensitivity, refers to a sharp, temporary pain caused by exposure of the dentine, which is the inner layer of the tooth. This exposure can occur due to enamel wear, receding gums, the presence of cavities, broken or chipped teeth, worn fillings, among other causes. It appears when the dentine becomes exposed. This dentine contains small microscopic tubules that connect the surface of the tooth to the dental pulp, where the nerves are located. When these tubules become exposed, external stimuli can trigger a painful response.

Causes

The causes of tooth sensitivity can vary and include:

1. Enamel wear: Tooth enamel can wear away due to aggressive brushing, bruxism (teeth grinding) or other factors, exposing the dentine.
2. Gum recession: Receding gums can expose the dentine along the gum line, increasing sensitivity.
3. Dental cavities: Cavities can affect the dentine and contribute to tooth sensitivity.
4. Dental treatments: Some dental procedures, such as tooth whitening or the placement of fillings, can cause temporary sensitivity.

Symptoms of tooth sensitivity

Tooth sensitivity shows itself through various symptoms, including discomfort when consuming cold, hot, sugary or acidic foods or drinks, as well as when breathing in cold air through the mouth.Other symptoms may include pain when biting, brushing your teeth or exposing your teeth to external stimuli.

How can you get rid of tooth sensitivity?

Here are the following tips for the treatment of tooth sensitivity:

1. Gentle brushing: Use a toothbrush with soft bristles and brush with gentle movements. Excessive pressure can wear down tooth enamel, contributing to sensitivity. The cepillo de oralb iO8 allows you to regulate the intensity with which you brush thanks to its pressure sensor.
2. Desensitising toothpaste: Choose toothpastes formulated to combat sensitivity. These toothpastes usually contain ingredients such as potassium nitrate or stannous fluoride, which help to block exposed dentinal tubules, such as OralB Sensibilidad y Encías.
3. Alcohol-free mouthwash: Avoid mouthwashes with a high alcohol content, as this can increase tooth sensitivity. Choose gentle, alcohol-free mouthwashes.
4. Dental floss: it is also important to use a good dental floss to prevent plaque from worsening the formation of cavities.

It is essential to address tooth sensitivity proactively, seeking guidance from a dentist for a personalised approach. Adopting proper oral care habits and using products designed to combat sensitivity are crucial steps in maintaining a healthy, comfortable smile.
