Orthodontics

Introduction

Orthodontics is a type of dental treatment that is used to improve the appearance, position and function of crooked or abnormally arranged teeth.

An orthodontist is a dental surgeon who specialises in orthodontic treatment and makes use of a range of appliances, such as braces. These are used to correct the position of teeth over a period of time, usually between 18 months and two years.

Orthodontics on the NHS

Orthodontic treatment is only available free of charge on the NHS for young people who are under 18 years of age and who have a clear clinical need for treatment.

A rating system, known as the Index of Orthodontic Treatment Need (IOTN), is used to assess the need and eligibility of individual cases. The IOTN is made up of five grades, which are listed below.

  • Grade 1 almost perfect teeth.
  • Grade 2: minor irregularities with the teeth, such as slightly protruding upper front teeth.
  • Grade 3: greater irregularities with the teeth do not require treatment for health reasons. For example, upper front teeth that protrude 4mm (0.15 inches) or less.
  • Grade 4: a severe degree of irregularity with the teeth that requires treatment for health reasons. For example, upper front teeth that protrude more than 6mm (0.25 inches).
  • Grade 5: severe dental health problems. For example, upper front teeth that protrude more than 9mm (0.35 inches).

NHS treatment is available for grade four or five cases. Grade three cases are usually judged on a case-by-case basis, and treatment may be made available if the appearance of the teeth is particularly unattractive.

Finding an orthodontist

If your dentist feels that orthodontic treatment for your child is clinically necessary, he or she will arrange a referral to an NHS orthodontist. In some areas the number of NHS orthodontists is limited, and waiting lists for treatment can range from six to 18 months.

The cost of private treatment depends on the type and duration of the treatment required. The average cost for a course of treatment is around £2,000-£2,500.

The website of the British Orthodontic Society provides a search facility for orthodontist services in your local area. See External links for more information.
