Abstract
Tooth decay is actually the destruction of the hard tissues of the tooth. This is caused by the acid attack due to the fermentation of carbohydrates due to bacterial attack by the bacterial species which colonize the mouth. Streptococcus mutans is the major cause of tooth decay. It occurs in different percentages in children of different ages. It is characterized by difficulty while eating, chewing, and even smiling. Clinical, radiographic, and technology-based methods are mainly used for the diagnosis of tooth decay.
