CAVITIES & TOOTH DECAY

Stages of Tooth Decay

STAGE 1: WHITE SPOTS

The first stage of tooth decay begins when chalky white areas on the surface of the tooth appear due to the loss of calcium and build-up of plaque. Bacteria in the plaque then begins to metabolize sugars from food consumed. The buildup of these acids causes tooth enamel to deteriorate, a process referred to as demineralization of the tooth surface. At this phase, tooth decay might still be reversible with the proper treatment––which should be discussed with your dental professional, such as using appropriate brushing technique, a fluoride toothpaste, and applying a topical fluoride treatment.

STAGE 2: ENAMEL DECAY

In stage two of tooth decay, the enamel starts breaking underneath the tooth’s surface. At this stage, the natural remineralization process is unable to restore the proper enamel and minerals, causing a lesion to form within the tooth. As the decay persists, the surface of the tooth risks breaking, which is irreversible. If one’s tooth breaks, one should seek dental attention immediately.

STAGE 3: DENTIN DECAY

Stage three of tooth decay is also known as dentin decay. If left untreated, bacteria and acids will continue to dissolve the enamel and the lesion risks reaching the dentin. The dentin is the part of the tooth that exists in between the enamel and the pulp. Once decay moves to the dentin, the level of pain begins to intensify and a sharp pain may be experienced in the infected tooth. When enough of the sub-surface enamel is weakened by the loss of calcium and phosphate minerals, the enamel collapses and a dental cavity is formed. At this point, a dental filling will most likely be required to restore the tooth.

STAGE 4: INVOLVEMENT OF THE PULP

The pulp is considered the tooth’s center. It is made up of living tissue and cells that are referred to as odontoblasts. Cells of the pulp produce dentin, which acts as the connective tissue between the enamel and pulp. If the pulp of a tooth gets infected with bacteria, pus then forms which inadvertently kills the blood vessels and nerves in the tooth. This is commonly known as a toothache and can cause constant pain. At this stage, the most common course of treatment is root canal therapy.

STAGE 5: ABSCESS FROMATION

Abscess formation is the final stage of tooth decay and by far, the most painful. Once the infection reaches the root tip of the tooth, the conjoining bones risk infection as well. The gums and tongue often swell which can affect speech and puts you at risk for other diseases. At this stage, additional oral surgery may need to be performed.

STAGE 6: TOOTH LOSS

If left untreated at each stage of tooth decay, the tooth will be lost and it must be extracted.

Tooth decay is easy to manage. Establishing an oral care regimen that involves these preventive measures will help avoid tooth decay.
