What causes sensitive teeth? 10 causes of sensitivity!

Created: January 17, 2023

Sensitive teeth are annoying and cause pain sensations with certain tastes and characteristics of food and drinks. Several causes underlie this problem, the main one being refractory gums. What are other causes of tooth sensitivity and what can you do about it to prevent or remedy this problem?

What are sensitive teeth?

Teeth consist of three different layers. The outer layer is called the tooth enamel and is the strongest. This is followed by the core of the tooth, which is made up of dentin or tartar, which is softer and contains many small canals. Finally, inside the core is dental pulp.

When you suffer from tooth sensitivity, you often experience a short and fierce twinge of pain. This occurs when the soft dentin in a tooth and the canals within it are exposed. This is because these tiny canals form a direct connection with the inner dental pulp and a pain stimulus occurs if you eat or drink something hot, cold, acidic or sweet.

What causes sensitive teeth?

Teeth feel sensitive because certain properties of food and drink trigger a reaction in the deeper layers of teeth. This reaction can have several causes, which are briefly explained below.

1. Receded gums

The main sensitive teeth cause is having receded gums, which expose the soft dentin of a tooth and cause the tiny canals to cause a pain stimulus when eating or drinking cold, hot, sweet or sour foods or drinks.

2. Acid erosion causes sensitivity

Certain acids in food and drinks attack tooth enamel and this process is also known as tooth erosion. This can eventually cause sensitive teeth.

3. Wear of tooth enamel

Tooth enamel is a hard layer, but it can gradually wear away, exposing the dentin underneath, resulting in tooth sensitivity.

4. Brushing teeth too hard as a cause of tooth sensitivity

Wear of tooth enamel can occur from certain foods or drinks, such as strong acids, but also from the way you brush. If you brush too often and hard, the enamel can wear away faster. Also, gums recede faster this way.

5. Cavities (caries)

Cavities in your teeth also affect the tooth enamel and the deeper structures, leading to sensitivity.

6. Cracked teeth

Cracked teeth or molars easily lead to exposed dentin, making it easier to trigger a pain stimulus.

7. Teeth grinding

Teeth grinding can cause gum and tooth enamel wear due to the high force. It often happens unconsciously during sleep.

8. Teeth whitening

During tooth whitening, enamel and gums are affected, which can cause sensitivity.

9. Overuse of mouthwash

Mouthwashes often contain harmful substances, including alcohol, which can dry out the mouth and damage teeth.

10. Dental visit

After a dental visit, your teeth may be more sensitive. If you continue to suffer from sensitive teeth, it is important to visit the dentist to find out the exact cause and prevent further problems.
