We provide a highly specialised orthodontic service for adults and children. We work with the oral and maxillofacial, restorative dentistry, ear, nose and throat (ENT) and respiratory services to provide care and treatment. The service is based at Queen Mary’s Hospital, Sidcup.

  • incorrect bites
  • severe facial disproportion in adults
  • sleep apnoea (interrupted breathing during sleep)
  • cleft lip, palate and craniofacial (head and face) problems

Preparing for your appointment

Referral criteria

We see patients:

  • with an orthodontic malocclusion that is graded 4 or 5 according to the Index of Orthodontic treatment need
  • who require multidisciplinary care with restorative dentistry, maxillofacial surgery or treatment by a specialist in Community Dentistry.

Special consideration will be given to medically compromised patients. We accept referrals from dentists and doctors. Patients must have healthy teeth, good oral hygiene and be registered with a dentist who they see for routine care before they start treatment.
