Living with Dentinogenesis imperfecta type 3

A rare, severe form of dentinogenesis imperfecta with discolored, see-through, weak teeth.

Understanding Dentinogenesis imperfecta type 3

Dentinogenesis imperfecta type 3 is a rare and severe form of dentinogenesis imperfecta, a condition that affects tooth development.

Teeth are generally discolored, most often blue-gray or yellow-brown, and translucent. They are weaker than normal and wear down, break, and may be lost. Both baby and permanent teeth are affected. GARD lists onset in childhood.

Signs & symptoms

GARD doesn't list a symptom list. Based on its summary, features include:

  • Blue-gray or yellow-brown teeth
  • See-through (translucent) teeth
  • Weak teeth that wear and break easily

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. Consider genetic testing

    Changes in DSPP are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Osteogenesis Imperfecta Foundation may keep lists of experts for this condition.
