Molars, also known as molars, are the innermost group of teeth, responsible for the main chewing role in the jaw, and are not in a position that is convenient for cleaning, so they are most susceptible to cavities. If molar cavities are not treated promptly, the small cavities will spread, enter the pulp and damage the pulp. Understanding the causes, how to self-detect and the progression of the disease will help you prevent and treat it properly.
