Alveolar bone is the part of the jawbone that supports the roots of the teeth. It forms the sockets, known as alveoli, where teeth are anchored. This bone is essential for dental health, as it provides stability and strength to the teeth during chewing and biting. The alveolar bone is made up of a dense outer layer called cortical bone and a spongy inner layer known as trabecular bone. It can be affected by various conditions, such as periodontal disease, which can lead to bone loss and tooth mobility. Maintaining good oral hygiene is crucial for preserving the health of the alveolar bone.
