There are many benefits to choosing invisible aligners over traditional orthodontic braces, or metal braces. Clear, plastic aligner trays are custom-fitted to your mouth for comfort and they can correct misalignment in as little as 12 weeks, depending on the brand and your particular case. They’re removable, so you can take them out to eat, drink, brush, and floss. Plus, they’re clear, which makes them practically invisible so you don’t have to feel embarrassed to wear them.
There are several different brands of invisible aligners available to UK residents, with a wide range of features and costs to consider. How can you choose the best invisible aligners in the UK? Here are a few things to consider.
How do Invisible Aligners Work?
Just like metal braces, invisible aligners correct misalignment and malocclusion by applying gradual pressure to teeth. The use of invisible aligners is overseen by dental and/or orthodontic professionals (depending on the brand) that create a personalized plan for swapping out aligner trays to continue shifting teeth until you enjoy perfect alignment.
Patients will receive several sets of custom-fitted aligner trays made from molded plastic, and with check-ins and supervision, they’ll progress through each set of trays until the process is complete and desired outcomes are achieved.

How Much do Invisible Braces Cost in the UK?
When seeking the best invisible aligners in the UK, pricing is sure to be a major factor in your overall decision. The first thing you need to know is whether braces are covered by insurance. The National Health System (NHS) only covers metal braces, and will pay 100% for patients under the age of 18. Coverage isn’t typically available for adults, unless braces are needed for health reasons, and then coverage must be approved on a case-by-case basis.
Invisible aligners are not covered by NHS, and they may or may not be covered by private insurance (you’ll have to check with your provider). This means that most people will have to pay out-of-pocket for invisible aligners, which makes pricing an important factor. Here’s a quick comparative breakdown of costs:
- SmileCo £1,399
Single payment or monthly payments starting from £138
- Straight My Teeth £999
