Tooth Anatomy, Decay and Care

The anatomy of a tooth is designed to endure the pressures of daily use, with layers that serve unique purposes. These layers include enamel, dentin, pulp, and cementum. Enamel, the hardest substance in the body, shields the tooth from external damage. Beneath it, the dentin provides support, while the pulp, at the core, is responsible for the tooth's vitality, containing nerves and blood vessels. Tooth decay occurs when harmful bacteria in plaque attack the enamel, causing cavities. This process is accelerated by poor oral hygiene, high sugar intake, and irregular brushing. To protect teeth from decay, regular brushing, flossing, and dental checkups are essential to maintaining a healthy, beautiful smile.
