Sensitive teeth often occur because the dentin in the root area is exposed due to receding gums or periodontal disease. This is a very common phenomenon and has a high prevalence.
When exposed, the root does not have the same enamel coating as the crown. Instead, the root has a thin outer covering called cementum. When the cement is gone, the dentin is exposed.
According to Doctor Vo Van Nhan: brushing too hard or using a highly abrasive toothpaste can also cause erosion of the enamel surface and expose dentin. A diet that is high in acids - for example, a lot of acidic foods, tarts, or sodas - can cause tooth wear and breakdown of tooth surfaces and lead to exposed dentin.
When your teeth are sensitive, you will feel pain when brushing. Thus, if you do not brush your teeth thoroughly because of pain, you will face more risk of tooth decay and gingivitis.

What causes pain in exposed dentin?
According to Doctor Vo Van Nhan: dentin contains thousands of tiny dentin tubules that can only be seen with a microscope. These tubules connect from the tooth surface, through the dentin, to the tooth's nerve center in the pulp.
These tubules contain fluid. After eating or drinking hot or cold foods, the fluid in these tiny dentin tubules moves and irritates the nerve fibers in the tooth, causing toothache.
The difference between tooth wear caused by grinding, by abrasion, and by erosion:
- Tooth wear due to teeth grinding: wear due to tooth-to-tooth contact.
- Abrasion: wear caused by foreign objects in contact with teeth such as toothbrush bristles, nails, hairpins, etc.
- Erosion: caused by contact of a chemical agent with the tooth such as lemon juice, gastric juice, ...
Brushing properly will help prevent tooth wear
Prevent sensitive teeth
You can reduce your risk of sensitive teeth by maintaining good oral hygiene to prevent receding gums and periodontal disease. Brush and floss properly according to your dentist's instructions. At the same time, using a low-abrasive toothpaste can help reduce the risk of sensitive teeth. In addition, an acid-free diet also helps prevent sensitive teeth.
Not treating sensitive teeth can lead to other dental problems, especially painful brushing that will prevent you from brushing well – this is a risk of tooth decay or periodontal disease.
