Key takeaways
Clear braces offer a discreet, removable way to align teeth without noticeable wires.
Metal braces remain the best choice for fixing complex bite issues and severe crowding.
Aligners can be popped out for meals and brushing, while metal braces stay fixed in place.
Clear trays are gentler on your cheeks and gums than sharp metal brackets and wires.
Caring for clear braces means taking trays out to eat, whereas metal braces require avoiding hard, sticky foods.
Metal braces are generally cheaper upfront, though at-home aligner services now offer affordable tray options.
Overall treatment time depends more on your case complexity and daily compliance than the appliance itself.
Clear aligners win on convenience and appearance, but metal braces dominate on durability and heavy-duty results.

Straighten teeth without metal brackets
Take our free assessment to see if aligners are an option for you.
Are clear braces right for you?

Clear braces or clear aligners work through a series of custom-made, virtually invisible plastic trays that gradually shift your teeth into place. Unlike fixed brackets, they're removable, which makes them one of the more flexible teeth straightening options on the market today. Here is how clear aligners work:
-
Custom-molded, transparent aligner trays fit snugly over the teeth.
-
Each tray in the series nudges teeth slightly further than the last, over roughly one to two weeks per stage.
-
They're designed to be barely noticeable and can be taken out for eating, brushing, or a big event.
Clear aligners are best for:
-
Adults and teens who want a low-profile treatment.
-
Professionals who'd rather not have visible metal in meetings or on camera.
-
Patients who value convenience and being able to remove their trays.
-
Mild to moderate cases, with many complex cases now treatable too.
Here's what our in-house dental expert says:
"In my practice, I've seen clear aligners work just as well as metal braces for most cases. The real win is that patients actually enjoy the process more because they're not stuck avoiding their favourite foods or struggling to floss."
— Dr. Ardra Kilaparti

Are metal braces right for you?
Metal braces work through stainless steel brackets and wires that stay fixed to the teeth and apply steady pressure until they move into place.
-
Continuous, controlled pressure nudges teeth into alignment over time.
-
It's one of the most established orthodontic treatments around, backed by decades of clinical use.
Metal braces are best for:
-
People with compliance issues.
-
People with moderate to severe orthodontic problems.
-
Anyone after a durable, cost-effective solution without extra fuss.

Appearance and discretion
Clear braces blend in almost completely, since the trays are transparent and sit closely over the teeth. That's exactly why they've become popular among adults and professionals who want discreet treatment.
Metal braces, by contrast, are highly visible by design. They keep the traditional look, though some patients lean into it and personalize the elastic bands with color.
Effectiveness
Metal braces are often the pick for severe crowding, complex bite correction, and heavily rotated teeth, since fixed brackets can apply more targeted force. If you wear the clear aligner trays as instructed, they are effective at delivering predictable results.
Durability
Metal braces use extremely strong stainless steel, so they resist breakage well and suit patients with busy, active routines. Clear braces are made from a durable medical-grade plastic, and since each tray only gets worn for a week or two before being swapped, everyday wear and tear matters less than it does with fixed brackets.
Comfort
Clear braces are easier on your gums since there are no wires or brackets involved. You can take them out entirely for meals. Metal braces have slightly sharper edges early on, and some temporary irritation is common while the mouth adjusts.
Maintenance
Caring for clear braces means:
-
Removing trays before eating or drinking anything besides water.
-
Cleaning trays regularly and brushing teeth before reinserting them.
-
Keeping up excellent daily oral hygiene throughout treatment.
Caring for metal braces means:
-
Brushing and flossing carefully around every bracket.
-
Avoiding sticky or hard foods that could bend a wire.
-
Sticking to routine orthodontic adjustment visits.
Staining
Clear aligner trays resist staining reasonably well, but if worn while eating or drinking, they can pick up color from:
-
Coffee
-
Tea
-
Curry
-
Tomato-based sauces
-
Colored beverages
Cost comparison
Clear braces cost anywhere from £6,00 for at-home aligner treatments to £5,500 for in-office options, making them one of the most budget-friendly teeth straightening treatment options around. Metal braces, on the other hand, typically run £1,800 to £8,000.
Treatment time
Clear aligners can offer a relatively short treatment time, from six to eight months, particularly when trays are worn as directed and changed according to the treatment plan. Metal braces, on the other hand, typically take 1 to 3 years to complete treatment, although the exact timeline depends on the complexity of the case and how well the treatment plan is followed.
Choosing between clear braces and metal braces
So, which is better: aligners or braces? It depends entirely on your goals, budget, and lifestyle. If you need a fixed, heavy-duty solution for severe misalignment, traditional metal braces remain a reliable clinical choice. But if you value discretion, comfort, and the freedom to eat whatever you like, clear aligners offer a modern, hassle-free alternative.
