Question

Bacteria act on the leftover food in the teeth and form option acid​

Answer 1

Answer:

Cavities commonly called as “Tooth decay” is damage to the outer protective layer of the tooth

It is the most prevalent chronic disease in both children and adults. Tooth Decay (Dental caries) happens when bacteria in mouth make acid that attacks the enamel. It can lead to cavities, which are holes in the teeth. If it is not treated well in time, it can cause pain, infection, and even tooth loss.

In most developing low-income countries, the prevalence rate of dental caries is high and more than 90% of caries is untreated. An estimated 5 billion people worldwide suffer from dental caries.

Answer 2

Answer:

These bacteria combine with food and constantly form a soft, sticky film called plaque. When we eat or drink foods containing sugars, the bacteria in plaque produce acid that attacks the tooth enamel.
