Anodontia or Hypodontia
Anodontia is a rare, genetic tooth disorder in which some or all teeth never form. Although it can affect baby teeth, it is more common with permanent teeth.
If a patient has complete anodontia, none of their adult teeth form. However, dentists more frequently see cases of partial anodontia in which one or more teeth are missing, but some teeth have formed. If six or more teeth are missing, that is referred to as oligodontia. Hypodontia refers to when between one to five teeth don't develop.
Anodontia, oligodontia, and hypodontia are genetic disorders, so they cannot be reversed or cured. Your child's dentist may recommend implants or dentures. It's important to seek treatment early for a child's oral health, ability to eat, speak, and breathe, jaw, and facial structure.
