Delayed or absent tooth formation; Teeth - delayed or absent formation

The timing of the first appearance of teeth varies. Most infants get their first tooth between 6 and 9 months, although earlier or later eruption may be normal.

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.

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
• Incontinentia pigmenti achromians
