NHS Treatment

Orthodontic treatment is available on the NHS for young people under the age of 18 years who have a clear clinical need for treatment. A rating system, known as the Index of Orthodontic Treatment Need (IOTN), is used to assess your eligibility for NHS treatment.

The IOTN consists of five grades:

  • Grade 1 – almost perfect teeth
  • Grade 2 – minor teeth irregularities, such as slight asymmetry or mildly protruding teeth
  • Grade 3 – greater teeth irregularities that do not usually need treatment for health reasons, such as a deep bite that doesn’t affect the use of your jaw
  • Grade 4 – severe teeth irregularities that need treatment for health reasons, such as having more or less than the normal number of teeth
  • Grade 5 – severe dental health problems, such as the disruption of normal skull and/or jaw development, or a large number of missing teeth

NHS treatment is available for grade 4 and grade 5 cases. Grade 3 cases are further assessed using the Aesthetic Component (AC).

The AC has 10 categories and uses a set of photographs to further assess the patients need on grounds of aesthetic impairment. The combination of DHC (Dental Health Component) and AC scores (in the form DHC.AC) gives a score of 3.1 to 3.10. To be eligible for free NHS treatment, the overall score must be 3.6 or higher.

We currently have a small waiting list to see new patients, however we are proud of getting all patients in for their initial assessment within a few months of referral. You will be able to book the initial 15-minute appointment at one of our practices, where you will be seen by one of our practitioners and assessed whether you qualify for the NHS treatment.

(A NHS assessment and subsequent review appointments do not guarantee that NHS treatment will be offered.)

After successfully qualifying for NHS care, we will get you into the treatment that best suits your case. One of our caring orthodontic practitioners will take you through the whole treatment; from correcting the profile and looking after your teeth, to retaining them in their new stunning smile. On average the NHS treatment will take between 18 and 24 months, depending on the complexity of the case.

If your child does not qualify under the NHS criteria, we can provide treatment on a private basis. We offer a range of treatment options at our clinics and a variety of payment methods. Please see our Private Treatment page.

“I am delighted with the treatment that I have received from Enhance Orthodontics, and cannot recommend them enough. The staff are friendly, helpful and are always willing to assist with a smile.

My only regret is that I didn’t get my teeth sorted sooner!”
