Adult braces cost in the UK: fixed braces vs clear aligners
For most adults, straightening teeth means paying privately, because NHS orthodontics is aimed at under 18s with a clear clinical need. That leaves a choice between traditional fixed braces and near-invisible clear aligners, and the cost depends heavily on which you pick and how much work your teeth need. The real prices below give you a realistic starting point for each route.
The quick version
- Adult braces are almost always private, as NHS orthodontics rarely covers over 18s.
- Fixed metal braces are often the most affordable option, with clear and ceramic versions costing more.
- Clear aligners like Invisalign are discreet but priced for the custom trays and convenience.
- Case complexity and treatment length drive the total more than the type of brace alone.
What people actually paid

Why the price varies so much
The type of brace sets the baseline, and traditional metal fixed braces usually come in lowest because the materials are cheaper and the technique is well established. Ceramic or clear fixed braces cost more for the tooth-coloured brackets, while clear aligners are priced around the custom-made trays and the lab work behind them. On top of that, how much your teeth need to move changes everything, since a long, complex correction means more appointments, more adjustments and a bigger fee than a quick tidy-up of the front teeth. Where you are treated matters too, with big-city practices generally charging more. Extras such as retainers to hold the result, plus any whitening once the braces come off, can sit inside the quote or be added separately, so it pays to ask what is really included.
How to pay less
- Consider fixed metal braces if discretion is not a priority, as they are often the cheapest route.
- Get written quotes from a few private dentists and orthodontists and compare what each covers.
- Ask about monthly payment or 0% finance so a larger fee is easier to manage.
- Check whether retainers are included, since replacing them later is an avoidable extra cost.
Common questions
Can adults get braces on the NHS?
Only rarely. NHS orthodontics is mainly for under 18s with a clear clinical need, such as a severe bite problem. Most adults wanting straighter teeth pay privately, whether that is fixed braces or clear aligners.
Are fixed braces cheaper than clear aligners?
Usually the traditional metal version is the most affordable, while clear and ceramic braces and aligners cost more. The gap narrows for simple cases, so it is worth getting quotes for both before deciding on price alone.
How long do adult braces take?
It depends entirely on how much your teeth need to move, from several months for minor work to a couple of years for a full correction. Longer treatment usually means a higher fee, because it involves more appointments and adjustments.
