Why is orthodontic treatment more expensive in London?

Usually not. Most standard UK dental insurance plans exclude orthodontic treatment or do not list it as a benefit. A smaller number of insurers and dental plans offer specialist orthodontic cover, but it typically has strict limits, waiting periods and exclusions, so read the policy wording and ask the insurer in writing whether fixed braces, clear aligners and retainers are covered.

NHS braces are free for eligible under-18s in England whose teeth meet the clinical need threshold (IOTN Dental Health Component grade 4 or 5, with grade 3 cases borderline), but waits can run to four years or more in some areas. Private braces are open to any age and any level of need, usually with appointments within weeks, and typically cost £1,500 to £8,000 or more depending on the appliance.
