How do braces and clear aligners work?
Teeth move when steady, gentle pressure is applied over time: the bone around the root slowly remodels, letting the tooth shift. Both braces and aligners use this same biology — they simply deliver the pressure in different ways.
Braces use small brackets bonded to the teeth, connected by a wire. The wire is adjusted at regular visits to guide the teeth into position. Clear aligners are a series of custom, transparent trays, each shaped slightly differently from the last. You move to a new set at regular intervals, and each set nudges the teeth a little further. Small tooth-coloured attachments are sometimes bonded to teeth to help aligners grip.
What can each one treat?
Clear aligners work well for many cases of mild to moderate crowding, gaps and some bite problems in adults and teenagers. Braces can handle the same problems and are generally better suited to complex movements — for example, large rotations, significant bite corrections or teeth that need to be moved vertically.
This is why an assessment matters. A dentist examines the teeth, takes X-rays such as an OPG panoramic view, and records the teeth (often with a digital scan) before recommending either option. Sometimes both are suitable; sometimes only one is.
How do they compare in daily life?
The biggest differences are in how they fit into your day:
- Appearance: aligners are nearly invisible; tooth-coloured braces are less noticeable than metal ones.
- Wear time: aligners must be worn about 20–22 hours a day and removed only to eat, drink anything other than water, and brush. Braces are always working.
- Eating: aligners come out for meals, so there are no food restrictions, but you must brush before putting them back. With braces, very hard or sticky foods can break brackets.
- Cleaning: aligners let you brush and floss normally. Braces need extra care — food and plaque collect around brackets, and special brushes help.
- Comfort: both cause pressure for a day or two after a change. Braces can rub cheeks and lips at first; aligners can feel tight with each new set.
- Responsibility: aligners depend on you wearing them as advised. If they are left out too often, teeth won't follow the plan.
Which one is faster?
Neither is reliably faster for everyone. Treatment time depends mainly on how far the teeth need to move and how complex the movement is. Braces are often worn for between one and two years; aligner treatment for simpler cases can be shorter, and longer for more complex ones. Missed wear time with aligners or broken brackets with braces both slow treatment down. Your dentist should give you an estimate before you start, and it can change as treatment progresses.
Am I too old for braces or aligners?
No. There is no upper age limit for straightening teeth as long as the teeth and gums are healthy. Adults often prefer aligners for their discretion, but braces remain a good option at any age. Any decay or gum disease is treated first, because moving teeth in unhealthy gums can cause harm.
For children, an early orthodontic check around age 7–9 helps spot developing problems in time, even if treatment starts later.
What happens after treatment?
Whichever you choose, teeth naturally tend to drift back towards their old positions. Retainers — removable or a thin wire fixed behind the teeth — hold them in place. Wearing retainers as instructed is as important as the treatment itself.

Common questions
Neither is better for everyone. Aligners are discreet and removable; braces can handle a wider range of cases and don't depend on daily wear. An assessment shows which suits your teeth.
Most people feel pressure or tightness for a day or two with each new set. This usually settles quickly.
Mostly, yes. Avoid very hard or sticky foods that can break brackets, cut food into smaller pieces and take extra care with brushing.
