Enamel is the tooth’s hardest outer layer, protecting against wear and decay. Beneath enamel lies dentin, a yellowish resilient tissue that supports enamel and transmits sensations to the pulp. The pulp is the tooth’s softcore, containing nerves and blood vessels that provide nutrients and sensory function. Gums are soft tissues surrounding the teeth, forming a protective barrier against bacteria and trauma. The alveolar bone anchors teeth in place, supporting their roots. The root canal is a passage within the root housing the pulp, including nerves and blood vessels, which enter through the root tip to nourish and innervate the tooth. #tooth #teeth #anatomy #oralhealth #gums #enamel #root
