Caries is the deterioration of the tissues that make up a tooth. This deterioration or destruction has its origin in acids that cause the bacteria that make up the plate. That white and viscous substance that is attached to the surface of the teeth and around the gum. These bacteria destroy the enamel, which is the hard layer that covers them; and it can also affect the underlying layer called dentin.
Properly stated, decay is a bacterial infection in a tooth. It is, in fact, the most common chronic childhood illness. It affects the so-called “milk teeth” of approximately 40% of children.
If the plaque is not removed, it sticks to the tooth; adhering strongly as a hard substance called Cavities tartar or calculus. When this happens, the gums become irritated and inflamed, giving rise to gingivitis and periodontitis.
The aggression of the acids erodes the enamel, creating carved areas called caries. In general, these do not hurt and therefore are not detected, unless they are very large; the tooth is badly damaged or the nerve is affected. When they hurt, they are already in an advanced stage and carry consequences such as the famous «phlegm on» or dental abscesses.
A caries that is not treated in time reaches the soft interior of the tooth or pulp. Then it is necessary to practice an excision of the nerve so that it does not hurt; and sometimes, only the solution remains as a solution.
Types of cavities
- Of crown. Crown caries are the most common type. It is the one that occurs in the chewing area of the tooth.
- Radicular. Root caries is the one that occurs when the gums retract and leave part of the tooth root exposed. The root is not enameled, so it can be easily affected.
Recurrent caries is formed when there is something between the teeth that can adhere plaque; as are the crowns or the seals.
