2/ The causes of tooth decay are less likely to be suspected

There are many causes of tooth decay that few people expect, such as:

  • Not brushing regularly: This can cause teeth and oral cavity not to be cleaned, creating a favorable environment for harmful bacteria to grow.
    Improper brushing: This can also be the cause of tooth decay. When brushing, brush along the teeth or in a circular motion and use a brush with thin, soft bristles to clean between the teeth. On the other hand, make sure the toothbrush is wide enough to be able to clean both the front and back of the teeth and the surface of the tongue.
  • Eating too much sweets: It will cause plaque to stick to the teeth, creating conditions for bacteria to grow, leading to cavities in the lower jaw, upper jaw, front teeth, …
  • Regularly snacking, soft drinks contain a lot of acids that are harmful to teeth: Put teeth at higher risk of decay
  • Lack of water in the body: Leading to dry mouth, the amount of saliva secreted is not enough to wash away food and plaque on the teeth.
  • Moreover, saliva also contains a lot of substances that can protect teeth
  • Broken, weak teeth: This condition will create conditions for bacteria to easily attack the tooth surface, forming stubborn plaque and causing tooth decay.
  • Person-to-person contact: Contact through household utensils, sharing dishes, etc. with people with tooth decay can also spread disease.
  • Digestive disorders, erratic eating: This is the ideal condition to promote the development of caries in the lower jaw, upper jaw,…
  • Receding gums: When the gums recede, it can cause plaque at the roots of the teeth to form, creating bacteria, attacking the dentin, even the roots. Thereby causing tooth decay, even many other more dangerous diseases

3/ Stages of tooth decay

Plaque formation: Initially, plaque will appear on the teeth due to the process of eating too much sugar and starchy foods but not being cleaned. These bacteria will begin to eat the remaining sugar and starch and form plaque on the teeth. Over time, plaque gradually hardens to form tartar. This is a shield for bacteria because this tartar layer is very hard and difficult to remove

The first stage: In the plaque contains acids. This amount of acid will remove the minerals present in the enamel and outside of the teeth. Gradually causing the teeth to erode and appear small holes in the enamel. When tooth enamel has been worn away, bacteria and acids can more easily attack the inner layers of the tooth or the dentin itself. In the dentin contains small tubes and they are in direct contact with the tooth nerve, so it is very sensitive

Stage of severe caries: The more advanced the tooth decay, the stronger the attack of bacteria and acids. They continue to move through the tooth, next to the tooth material and inside the pulp, which contains blood vessels and nerves. When tooth decay eats into the pulp, the pulp chamber becomes swollen and irritated. The swelling is expanding but there is not enough space to contain it, leading to the compression of the nerves and causing pain for the person with tooth decay.
