Braces and clear aligners such as Invisalign move teeth the same way, and both work well in the right case. The choice usually comes down to two things: how complex your bite is, and whether you will wear aligners for 22 hours a day. Here is how an orthodontist decides between them.
What each one is, and how it moves teeth
Both work the same way underneath. Teeth move when steady, gentle pressure is applied over months, and the bone around the root remodels to let the tooth shift. Fixed braces apply that pressure through brackets bonded to each tooth and a wire that connects them. Clear aligners apply it through a series of custom plastic trays, each one moving the teeth a small step before you change to the next. The American Association of Orthodontists describes aligners as nearly invisible shells that sequentially apply the pressure needed to move teeth.
The difference is in how that pressure is delivered. Braces are fixed in place and always working. Aligners come out.
An aligner only works while it is in your mouth. It has to be worn at least 22 hours a day, out only to eat and brush. Braces keep working around the clock.
That is the heart of the choice. The removability that makes aligners convenient is also their weakness. Cleveland Clinic and the AAO both put the minimum at 22 hours every day. Wear them less and the teeth stop tracking the plan, the trays stop fitting, and treatment stalls or has to be restarted. If you already suspect you would leave them out, braces are usually the more reliable choice.
The types of braces
Metal braces use stainless steel brackets and are the most durable option, which is why they are often chosen for complicated movements. Ceramic braces work the same way with tooth-coloured brackets, so they are less visible. The trade-off, as Cleveland Clinic notes, is that ceramic brackets are more fragile and break more easily.
When braces are the better choice
The AAO says plainly that clear aligners are not right for everyone. Some corrections are more predictable with fixed braces: severe crowding, large gaps between the upper and lower teeth, badly rotated teeth, and cases that need extractions or long tooth movements. An orthodontist may also combine the two, with a short phase of braces followed by aligners. Either way, the choice should be made from your bite.
Braces and Invisalign, side by side
Which column suits you depends on what your teeth need and how you live.
What patients ask about most
- How long will it take. The ADA puts most orthodontic treatment at one to three years, and the case decides the time more than the appliance does. A complex bite takes about as long to correct either way.
- Will it hurt. Both feel tight or sore for a few days after each adjustment or new tray, as the teeth start to move. It feels like pressure, and it settles.
- What will it cost. That depends on how complex your case is, which appliance you choose and, for aligners, how many trays you need. We give you a written plan with the cost after examining your bite, before anything starts.
- Am I too old for this. Adults are a big share of orthodontic patients: the AAO reports that one in three orthodontic patients today are adults, and the ADA confirms healthy teeth can be moved at any age. Treatment can take a little longer in adults because the teeth are more settled.
Retainers are for life
Once the braces come off or the last aligner is done, teeth drift back towards where they started unless something holds them. Cleveland Clinic is direct about it: you wear a retainer full time at first, then at night, and in practice for the rest of your life. Straightening the teeth is the active phase; keeping them straight lasts for good. Any plan you are offered should include retainers, because teeth can always move back.

We offer metal braces, ceramic braces and Invisalign for children and adults from Malad, Kandivali, Goregaon and across Mumbai, and we recommend the option your bite calls for. The clinic is ISO 9001 certified.
Is Invisalign better than braces?
Neither is better in general. Aligners suit mild to moderate cases in people who will wear them 22 hours a day, and braces handle the widest range of corrections.
How many hours a day do I have to wear aligners?
At least 22 hours a day, taken out only to eat, drink anything other than water, and brush.
Do I need a retainer after braces or Invisalign?
Yes. Teeth drift back without one, so you wear a retainer full time at first and then at night, for life.
