Dental Caries (Tooth Decay)
Dental Caries
Dental caries (tooth decay) is a disease in which acid produced by bacteria in the mouth dissolves and damages the hard tissue of the tooth. It is known to cause almost no symptoms at first, with pain and damage growing as it progresses.
In plain terms
Put simply, tooth decay is acid made by bacteria dissolving the tooth little by little and opening a hole in it. At first it does not hurt, but as it deepens the tooth becomes sensitive and painful.
Dental caries progresses as acid, produced when bacteria in plaque break down sugars, demineralizes the enamel and dentin. At the early demineralization stage, fluoride application and care can slow the progression, but once it advances, a filling (such as resin), root canal treatment or a crown may be needed.
For prevention, correct brushing, floss and interdental brushes, controlling sugar intake, and regular check-ups and scaling are known to help. For children’s molars, sealants (filling the grooves of the teeth) may be recommended for preventive purposes.

Frequently asked questions
- Q. How can I tell if I have early tooth decay?
- Early decay is known to cause almost no symptoms, which makes it difficult to notice yourself. Early detection through regular check-ups and radiographic examination is recommended, and with check-ups at 6-month intervals it can be managed at an early stage. If there is sensitivity or pain, it has often already progressed, so prompt care is advisable.
