Question

How tooth decay cause ?

Answer 1

Explanation:

Tooth decay occurs when foods containing carbohydrates become trapped between teeth and are not completely removed with brushing and flossing. The plaque bacteria generate acidic by-products that eat away at the tooth enamel, slowly creating holes in the teeth called cavities. Without treatment, these holes can grow larger over time and may even destroy the whole tooth.Major causes of tooth decay are sugary, sticky foods and beverages. The more sugar consumed, the more acid, which gets produced leading to decay. Sugar combines with plaque to weaken the enamel leaving you vulnerable to tooth decay. Each time you eat a sugary snack, your teeth are vulnerable to damage from the acids for the next 20 minutes. It is important to understand the causes of tooth decay so you can learn the proper way to care for your teeth and care for your health.

Tooth decay starts when the mouth's pH is below 5.5. In addition to food particles, masses of bacterial cells bind to the teeth to form dental plaque. Since plaque coats the teeth, saliva can not reach the tooth layer to neutralize the acid.
