Living with Amelogenesis imperfecta

A group of conditions in which tooth enamel doesn't form properly, leading to small, discolored, pitted, or fragile teeth.

Understanding Amelogenesis imperfecta

Amelogenesis imperfecta is a group of disorders of tooth development in which tooth enamel doesn't form properly.

Teeth may come in later than usual and can be small, discolored, pitted, or grooved. The upper and lower teeth may not line up. People often have trouble eating, food and drink sensitivity, and pain when brushing. Teeth can wear down quickly, get cavities often, and break. It affects both baby and adult teeth.

Signs & symptoms

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

  • Discolored teeth
  • Soft or weak tooth enamel
  • Fragile teeth
  • Trouble chewing
  • Upper and lower front teeth that don't overlap (open bite)
  • Thin or underdeveloped enamel

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.
