Underneath the dentin lies the cementum. Cementum is about the same hardness as bone tissue. It covers the surface of the root and serves as the anchor point for connecting the tooth to the bone. Periodontal ligaments attach to the cementum and the jawbone, anchoring the tooth in place and giving it stability.
