What Causes Tooth Decay?

Tooth decay is a common dental problem worldwide. It is characterised by damage to the tooth surface and gradually weakens the structure of the tooth. Tooth decay has many causes, and various factors may affect its development. In this article, we will examine the causes of tooth decay and methods of prevention in detail.

1. Eating Habits

Eating habits play an important role in tooth decay. Excessive consumption of sugary and acidic foods in particular can trigger decay. Sugary foods and drinks encourage bacteria in the mouth to multiply and produce acid. These acids weaken tooth enamel and lead to cavities. Frequent snacking or continually consuming acidic drinks may also increase tooth decay.

2. Inadequate Oral Hygiene

Inadequate oral hygiene is one of the most common causes of tooth decay. Failing to brush regularly, clean between the teeth and use dental floss leads to bacterial accumulation and plaque formation. Plaque is a sticky layer in which bacteria collect and remain on the surfaces of the teeth. Over time, plaque produces acid and causes tooth decay.

3. Bacteria and the Oral Flora

Bacteria in the mouth play an important role in the development of tooth decay. In particular, a type of bacterium called Streptococcus mutans feeds on sugary foods and releases acid. These acids weaken tooth enamel and cause cavities. An imbalance in the oral flora may also increase the risk of decay. Factors such as antibiotic use, immune-system problems or changes in the pH of the mouth may disrupt the balance of the oral flora and contribute to the development of cavities.
