If you've been thinking about straightening your teeth, you've probably narrowed it down to two options: clear aligners like Invisalign, or traditional fixed braces. Both work brilliantly — but they suit different people, different budgets and different lifestyles. Here's an honest comparison to help you decide.
How each treatment works
Fixed braces use brackets bonded to your teeth, connected by a wire that your dentist or orthodontist adjusts every four to six weeks. The constant, controlled pressure moves teeth into position — and because the braces never come off, they work around the clock without any effort from you.
Clear aligners are a series of removable, near-invisible plastic trays, each worn for one to two weeks. Every tray nudges your teeth slightly further along a digitally planned path. At our practice we offer two aligner systems, which means we can match the system to your case rather than forcing your case to fit one system.
The head-to-head comparison
| Clear aligners | Fixed braces | |
|---|---|---|
| Appearance | Nearly invisible | Visible (metal); ceramic is subtler |
| Typical treatment time | 6–18 months | 12–24 months |
| Typical UK private cost | £2,500–£5,500 | £1,500–£4,200 (metal) |
| Eating | Remove trays — no food restrictions | Avoid hard, sticky, chewy foods |
| Cleaning | Brush and floss as normal | Trickier around brackets and wires |
| Check-ups | Roughly every 6–8 weeks | Roughly every 4–6 weeks |
| The catch | You must wear them 20–22 hours a day | You can't take a day off from them |
The honest pros and cons
Aligners win on discretion and convenience. You take them out to eat, so there are no banned foods, and brushing and flossing carry on exactly as before. For adults in client-facing jobs — or anyone who simply doesn't fancy eighteen months of visible metal — that discretion is usually the deciding factor.
But aligners demand discipline. They only work while they're in your mouth, and that means 20–22 hours a day, every day. If you know you'll leave them in a drawer "just for the weekend", fixed braces will get you a better result, because they never rely on willpower.
Fixed braces also remain the stronger choice for complex cases — severe rotations, large bite corrections and significant crowding — where the wire-and-bracket system gives finer control. Part of any good consultation is being told honestly which category your teeth fall into.
What about afterwards?
Whichever route you take, teeth have a long memory. Retainers — usually worn nightly — are a lifelong commitment after any straightening treatment, and skipping them is the single most common reason people end up straightening their teeth twice. Budget for retainers (typically £60–£500 depending on type) as part of the treatment, not an optional extra.
So which should you choose?
As a rule of thumb: if your case is mild to moderate and you'll be disciplined about wear time, aligners give you a discreet, flexible treatment. If your case is complex, or you'd rather the treatment didn't depend on your habits, fixed braces are the safer bet. Many patients are surprised which category they're in — which is why we always start with a proper assessment and a scan rather than a guess.
