Tooth decay and cavities
Let's start by building a model of a tooth and its surrounding structures.
The socket is lined on the inside by a periodontal ligament.
Protecting the alveolus on the outside, is a layer of soft, supportive tissue called the gingiva, or gums, that sits on top of the bone and covers the root surface from the bone to the cementoenamel junction - where the cementum and enamel come together.
The root is covered by cementum, which is a bonelike substance that the periodontal ligament’s fibers attach to.
Next, there’s the neck, which is the transition between the root portion covered by bone and the crown.
When the teeth are developing, enamel is made before the tooth erupts into the mouth by a group of cells called the ameloblasts that die once the tooth erupts - meaning that the teeth lose the ability to make more enamel forever.
Dental caries, also known as tooth decay or cavities, is a common condition in which the hard outer layer of the tooth (enamel) is damaged by acids produced by bacteria in the mouth. This can lead to holes or pits in the tooth, which can cause pain, sensitivity, and other dental problems if left untreated. Factors that can contribute to dental caries include poor oral hygiene, a diet high in sugar and refined carbohydrates, dry mouth, and certain medical conditions. Treatment for dental caries typically involves removing the damaged area of the tooth and filling it with a dental material.
