In some cases, children or adults are missing teeth they never developed. In such cases cosmetic or orthodontic dentistry can correct the absence of those teeth.

Common Causes:

Specific diseases can have a profound effect on tooth shape, tooth color, time of appearance, or tooth absence. Delayed or absent tooth formation can result from many different conditions, including:

• Down syndrome
• Hypothyroidism
• Hypoparathyroidism
• Ectodermal dysplasia
• Ellis-van Creveld syndrome
• Cleidocranial dysostosis
• Apert's syndrome
• Progeria
