Living with Anodontia

A dental condition in which a person has no teeth, often with changes in hair, nails, or sweat glands.

Understanding Anodontia

Anodontia is a dental condition in which a person is missing all of their teeth.

Baby (primary) teeth, adult (permanent) teeth, or both may be missing. In most cases it is linked to a group of conditions called ectodermal dysplasias. In those cases, the hair, nails, and sweat glands are also affected.

Signs & symptoms

GARD doesn't list specific symptoms for this condition, but its summary describes these features:

  • Complete absence of teeth
  • Missing baby (primary) teeth
  • Missing adult (permanent) teeth
  • Changes in the hair, nails, or sweat glands (in many cases)

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.

  4. Connect with expert centers

    National Foundation for Ectodermal Dysplasias may keep lists of experts for this condition.

Everyday life

Living with a rare condition is easier with support.

  • Connect with National Foundation for Ectodermal Dysplasias
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Is my anodontia part of an ectodermal dysplasia?
Should my hair, nails, and sweat glands be checked too?
Would genetic testing help me understand the chance of passing this on?

Quick facts

InheritanceAutosomal Recessive

GARD says changes in genes (also called variants) cause anodontia. It is autosomal recessive, meaning a child inherits a changed copy of the gene from each parent.

Genetic

Also known as: agomphiasis; agomphosis; anodontia vera; anodontism; complete absence of teeth; complete agenesis of all teeth
