Tooth decay is a condition of the teeth that is caused by bacteria that produce acid. It is the result of an imbalance between the acid-producing bacteria and the natural defenses of the teeth. When the bacteria are left unchecked, they can cause damage to the enamel and dentin of the teeth.
Tooth decay can take on many different forms, depending on how severe the decay is and the type of bacteria involved. In its earliest stages, tooth decay may not be visible to the naked eye. Often, the only sign of decay is a change in the color of the affected tooth, usually becoming darker or yellowish.
As tooth decay progresses, it can become more visible. The tooth may become pitted or chipped, and the enamel may become flaky or discolored. In more advanced stages of decay, the tooth may become soft and brittle and holes may form in the enamel.
If tooth decay is not treated, it can eventually lead to serious damage to the tooth and the surrounding teeth. The decay can cause the tooth to become loose, and in some cases, it can completely destroy the tooth. In its most severe stages, the infection can spread to the bone and gum tissue, leading to further damage.
It is important to monitor the health of your teeth and seek treatment if you notice any signs of tooth decay. If treated early, tooth decay can be reversed, but if left unchecked it can lead to serious health problems.
