Tooth decay, which manifests in cavities, is a condition in which a hole forms in the tooth. This decay graduates from a small cavity to a much larger if the person does not treat it. One problematic feature in the beginning is its painlessness; due to no pain, the person might think that the problem is even there. That is why doctors always recommend regular checkups with the dentist.
Tooth decay or tooth cavities are reportedly a very commonly occurring health issue related to the mouth across almost all countries. No age is specifically protected from tooth decay, not even infants.
