Invisalign vs Fixed Braces: Which Should You Choose?
Dr Nader Gavgani, GDC 75484Published 7 min read
Invisalign or fixed braces — how to actually decide
Invisalign uses a series of clear, removable aligner trays to move teeth gradually; fixed braces use brackets and wires bonded to the teeth that stay in place until treatment ends. Both straighten teeth effectively — the real difference is what each one asks of you day to day.
Most people arrive already leaning towards Invisalign, because it's less visible. That's a reasonable instinct, but it isn't the whole decision — aligners only work if you actually wear them for 20 to 22 hours a day, and a fixed brace works whether you remember to do anything or not.
Aligners come out to eat, drink anything but water, and brush. That's the whole trade-off in one sentence — total freedom, entirely dependent on your own discipline.
Invisalign vs fixed braces, in full
The six-point version is on our Invisalign page. Here's the longer answer.
| Invisalign clear aligners | Fixed (conventional) braces | |
|---|---|---|
| Visibility | Clear — most people won't notice | Visible brackets and wires |
| Removable? | Yes, for eating and cleaning | No — fixed until treatment ends |
| Food restrictions | None, because you take them out | Hard, sticky and chewy foods must be avoided |
| Depends on your discipline | Entirely — 20–22 hours a day, every day | Very little — it works regardless |
| Sport and instruments | Straightforward — remove for contact sport | A mouthguard is fitted over the brackets |
| Typical price here | from £3,500 | from £2,000 per arch |
| Consultation | Complimentary | Priced at assessment |
The honest trade-off is discipline, not cost or comfort. If you know you'd leave the aligners out more than you'd wear them, a fixed brace may genuinely suit you better — and we'd rather tell you that than sell you the more expensive option that won't work for your habits.
When each one is the better choice
Invisalign tends to suit you if…
- You're an adult who didn't have treatment as a teenager and would rather it wasn't obvious now.
- Your case is crowding, gaps, or a mild-to-moderate bite issue rather than a jaw-position problem.
- You can genuinely commit to wearing trays most of the day, every day, for the length of treatment.
Fixed braces tend to suit you if…
- You know your own discipline isn't there for something removable.
- The movement needed is more complex than aligners handle well.
- Cost per arch matters more to you than visibility during treatment.
This is general guidance, not an assessment of your own teeth — the right answer for your bite is confirmed at a consultation, not guessed from a list.

Questions
Frequently asked questions
Can I switch from fixed braces to Invisalign partway through?
Sometimes, depending on how much movement is left to do and what the remaining plan looks like. It needs a fresh assessment rather than an assumption either way — ask at your next appointment.
What happens if I lose or damage an aligner?
Tell us straight away rather than skipping ahead to the next set in the sequence, which can move your teeth off the planned path. We'll advise whether to wear the previous tray again or have a replacement made.
Is one option faster than the other?
Not reliably — treatment time depends on how much movement is needed, not on which system is doing the moving. Invisalign is typically around a year; a fixed brace's timeline is confirmed at assessment in the same way.
