Genetically altered enamel formation.
← All explanationsAmelogenesis imperfecta
What is an inherited enamel formation disorder?
Amelogenesis imperfecta comprises genetic disorders of enamel formation. Depending on the type, enamel may be too thin, insufficiently mineralized or less resistant. Primary and permanent teeth can be affected. The changes arise during tooth development rather than from inadequate brushing.

Enamel develops differently
The outer tooth layer does not form normally during development. Thickness, hardness and appearance vary between types.
Assess the pattern
Sensitivity, wear and colour changes can occur. Examination, developmental history and sometimes specialist assessment distinguish other enamel disorders.
Plan long-term protection
Age, symptoms and remaining tissue guide care. Protection, suitable cleaning and restorations where needed are planned through development.

Often confused
Amelogenesis imperfecta and MIH
Both can alter enamel. Amelogenesis imperfecta is a genetic group of conditions; molar-incisor hypomineralisation typically affects particular permanent molars, sometimes incisors, and is classified differently.
Quick answers
Is poor brushing the cause?
No. The underlying formation disorder is genetic. Good cleaning nevertheless remains important.
Does every yellow or mottled tooth have it?
No. Many conditions cause colour or enamel changes, so examination is needed.
Do affected children immediately need crowns?
Not as a general rule. Age, tooth development, sensitivity and remaining tissue guide staged care.

For a personal discussion
Editorially suggested question to discuss with Dr Niusha Barahmand Pour:
Which enamel condition is present, and how can the teeth be protected appropriately for age?
An examination of unusual enamel or sensitive teeth can clarify whether specialist assessment is appropriate.
