What causes teeth to disintegrate?

Teeth disintegrate primarily due to tooth decay, which is caused by the accumulation of plaque—a sticky film of bacteria that produces acids when it interacts with sugars from food. These acids erode the enamel, the protective outer layer of the tooth, leading to cavities and potential tooth loss. Other factors contributing to tooth disintegration include poor oral hygiene, a diet high in sugar and acids, and certain medical conditions that affect saliva production and pH levels in the mouth. Additionally, physical trauma or grinding of teeth can also lead to structural damage.
