Orthodontic acceptance criteria

All referrals should be from a dentist only to avoid inappropriate referrals and avoid unnecessary delay for your patient.

A completed Orthodontic Referal form should be sent to:

The Royal London Dental Hospital,

Appointments Centre,

First Floor,

9 Prescot Street,

London,

E1 8PR

Or emailed to: bhnt.Orthodontics.nhs.net

Please note that we no longer accept fax referrals. All proformas must be electronically completed and hand written forms will be returned

  • Referrals will be accepted for advice and treatment planning only. Those patients meeting our acceptance criteria; in relation to both objective need for treatment (IOTN) and also treatment complexity, will be accepted for comprehensive treatment. Patients who are not dentally fit will not be accepted and should not be referred in the first instance unless they are fit for treatment.
  • Those patients who are accepted for treatment will be expected to continue to be registered with a general dental practitioner.
  • Patients can only be accepted where we have capacity to care for them.
  • NHS England is committed to monitoring for the quality of referrals to secondary care. 

The following patients will be accepted for orthodontic assessment:

  • Patients under the age of 18 years with high treatment need requiring complex orthodontic or multidisciplinary treatment. This encompasses patients having ‘great’ (IOTN 4) or ‘very great’ (IOTN 5) need for treatment, only where the required treatment is complex.
  • Patients will not automatically be accepted for treatment based on IOTN score; and the complexity of treatment will first be assessed.
    • For example, where a patient has only crowding; or a patient has only an increased overjet; or a patient who has hypodontia with only one missing tooth per quadrant, or there is no need for the prosthetic replacement of any teeth, we may discharge them for and suggest onward referral to a specialist orthodontic practice.
  • Patients with significant skeletal discrepancy eligible for combined orthodontic-surgical (orthognathic) (Royal London or Whipps Cross) care.
  • Patients with developmental absence of teeth (hypodontia) (Royal London or Whipps Cross) meeting specific acceptance criteria.
  • Patients with cleft lip and palate (Royal London only) according to our eligibility criteria
