Tooth anomalies may occur, such as lack of tooth buds for one or more teeth (hypodontia), small/thin teeth and short tooth roots. Snoring is common. Impaired oral motor function occurs and may cause speech and eating difficulties, as well as drooling.

Advice on follow-up and treatment

  • Early contact with dental services for intensified prophylactic care and oral hygiene information is essential.
  • Regular check-ups of dental and jaw development. Orthodontist should be consulted when needed.
  • Extra care is recommended in orthodontic treatment of patients with short tooth roots.
  • Snoring problems should be investigated by a physician in cases of suspected sleep apnea (frequent breathing pauses during sleep).
  • Oral motor training may be required in cases of eating difficulties, speech impairment and drooling.
