However, in reality, many cases still have tooth decay even though oral care has been done quite carefully. Dental experts believe that tooth decay is a disease with many factors affecting it, not only depending on brushing teeth.
High-sugar and starchy diet
One of the common causes of easy tooth decay is a diet high in sugar or starch. When these foods remain on the teeth, bacteria in the oral cavity will break them down and create acid. This acid reduces the pH in the mouth, thereby causing tooth enamel loss and forming cavities.
According to dental experts, brushing teeth only helps remove part of the plaque, while if the habit of eating sugary foods is prolonged, the risk of tooth decay still increases significantly.
Bacteria in tooth plaque
Even when teeth are cleaned, bacterial plaque can still form again after only about 24 hours. This biofilm contains many bacteria such as Streptococcus mutans, which can ferment carbohydrates and create acids that destroy tooth enamel.
Dr. Nigel Carter, an expert at the Oral Health Foundation (UK), said: "Brothels are the result of a combination of bacteria, food and time. Brushing is very important but not the only factor determining the risk of tooth decay.
Weak enamel or constitutional factors
Some people have weak enamel, poor mineralization, or more easily damaged teeth structure. In this case, enamel can be attacked by acid faster, causing a high risk of tooth decay even though oral hygiene is relatively good.
Experts recommend that, in addition to brushing your teeth properly, you should limit sweets, use dental floss and have regular dental check-ups to detect oral problems early.
