Usually 18 to 24 months for fixed braces, plus a retainer afterward.
NHS inform says good results typically arrive within 18 to 24 months of starting treatment when appliances are worn as instructed, and the NHS braces page says fixed braces stay on for 1 to 2 years. Adjustment appointments run every 6 to 8 weeks, and each one reactivates the movement. What stretches the timeline: missed appointments, broken brackets, not wearing elastics, and poor cleaning that forces pauses. What comes after matters as much: retainers hold the teeth while the surrounding gum and bone adjust to their new positions, and without them teeth drift back.
What to do
Common questions
How long do braces take?
Plan on one to two years. NHS inform says orthodontic treatment usually achieves good results within 18 to 24 months, and the NHS braces page says fixed braces, the kind most NHS patients get, typically stay in place for 1 to 2 years. Mild crowding can finish in under a year; complex bite corrections and adult cases can run past two. You will see the orthodontist every 6 to 8 weeks for adjustments, and those appointments are what keep teeth moving on schedule, so skipped visits stretch the finish date. The same goes for broken brackets and ignored elastic bands: braces are a partnership, and the patient controls more of the timeline than they expect. When the braces come off, you are not done: you will wear a retainer, sometimes full-time at first and then at night, because teeth drift back toward their old positions while the surrounding gum and bone adjust. Ask your orthodontist for their estimate at the fitting appointment, since your specific bite sets your specific clock.
