Living with Ankylosis of tooth

A rare dental condition in which a tooth fuses to the jawbone, losing the small ligament space around it.

Understanding Ankylosis of tooth

Ankylosis of tooth is a rare dental disorder with loss of the periodontal ligament space and of normal tooth mobility.

The periodontal ligament space is the small gap that normally lets a tooth move slightly in its socket. In this condition it is lost. It can occur at a variety of ages.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Teeth that don't move at all in the jaw
  • Tooth enamel differences
  • Fewer teeth than usual (tooth agenesis)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include genetic specialists and gum, teeth and mouth specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
