Gingiva and periodontal ligament
The gingiva covers and protects the tooth-supporting tissues, while the periodontal ligament anchors each tooth and senses pressure.
The short answer
The gingiva is the soft tissue around the teeth and alveolar bone. The periodontal ligament is a specialised connective-tissue layer between cementum on the root and the socket wall; it suspends the tooth and transfers chewing forces.
How does the periodontal ligament support each tooth?
Ligament fibres attach the root to bone and contain blood vessels and sensory nerves. Their pressure receptors help regulate chewing, while the gingiva forms a protective seal around the tooth neck.
How can you protect the gumline and tooth support?
Protect both tissues by brushing the gumline gently, cleaning between teeth, and avoiding habits that repeatedly overload or injure teeth. Dental examinations measure gum attachment, pockets, tooth mobility, and bite when problems are suspected.
Which changes mean your tooth support needs dental care?
See a dentist for bleeding, swelling, recession, pain on biting, tooth mobility, or a sudden change in how the teeth meet. These symptoms can involve gingiva, ligament, bone, pulp, or more than one structure.
How can the dentist identify injured supporting tissues?
Which tissue is causing the symptom, and will probing, mobility testing, bite checks, or radiographs show damage to the attachment or supporting bone?

Can home care replace a dental examination?
Home care can reduce irritation and plaque, but it cannot diagnose or remove causes such as decay, infection, calculus, cracks, or attachment loss.
