Tooth cavity or Dental Caries


Dental Caries is defined as an infectious micro biologic disease of the teeth that result in loss of tooth structure. In simple words or in layman language it is called as tooth cavity.


It is derived from the Latin word “rot”or decay



The interesting fact about caries is that prehistoric man rarely suffered from this type of tooth destruction so it can be considered as a disease of modern civilization.




Tooth decay or dental caries is increasing at an alarming rate in developing countries.

The presence of sucrose in modern diet has been associated with increased caries prevalence.


The microorganism or bacteria in the mouth produce enzymes which reacts with carbohydrate to produce acid. The acid produced interacts with tooth outer surface(enamel ) which leads to dental caries.


The acid can damage tooth surface creating tiny holes in teeth known as tooth cavity. These holes can affect the whole structure of tooth reaching pulp of the tooth.

Tooth pain occurs when cavity reaches pulp where the nerve in the tooth are exposed.
