Living with Dentinogenesis imperfecta

A tooth development condition that makes teeth discolored, see-through, and weaker than usual.

Understanding Dentinogenesis imperfecta

Dentinogenesis imperfecta is a condition of tooth development that causes discolored, translucent, and weaker teeth.

Teeth are most often blue-gray or yellow-brown. They wear and break easily and may be lost. Both baby and permanent teeth are affected. Type I occurs in people with osteogenesis imperfecta (brittle bones). Types II and III usually occur in people without other inherited disorders.

Signs & symptoms

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

  • Grayish, discolored teeth
  • Fragile teeth
  • Weak tooth enamel
  • Abnormal tooth roots
  • Abnormal dental pulp
  • Loose, double-jointed joints

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

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

InheritanceAutosomal Dominant

GARD doesn't name a gene. It lists autosomal dominant inheritance, so a changed copy of the gene from one parent can be enough.
