Invisalign vs braces: how clear aligners and braces compare

Invisalign is one brand of clear aligner. Clear aligners and braces are the two tools orthodontists use most to move teeth, according to the American Dental Association (ADA). Both can work well. The better choice depends on your teeth, your bite and how you live, and only an exam by a dentist or orthodontist can tell you which fits your case. This guide explains the differences in plain words so you can ask better questions at the consultation.

How each one moves teeth

Braces are small brackets bonded to the teeth and joined by a wire. The dentist or orthodontist adjusts the wire over time, and the steady pressure moves the teeth and can help guide the jaw. Brackets can be metal or tooth colored, and some are placed behind the teeth. Elastics (rubber bands) are often added to correct the bite. (ADA; AAO)

Clear aligners are a series of thin plastic trays made to fit your teeth. Each tray is slightly different, so each one moves the teeth a small step. The American Association of Orthodontists (AAO) says each aligner is typically worn for about one week, at least 22 hours a day. Small tooth-colored bumps (attachments) are often bonded to some teeth to give the trays something to push against. The ADA notes that aligners should be used under the direct supervision of a dentist or orthodontist.

What each one treats

The AAO lists gaps, crowding, overbite, underbite, open bite, crossbite and crooked teeth among the conditions clear aligners commonly treat. It also says aligners are not right for everyone, and that some cases are treated more predictably with braces. Braces are a common choice for complex tooth movements and bite problems, and some plans use both.

Research points the same way. A 2019 systematic review in BMC Oral Health (Ke and colleagues, 8 studies) found both aligners and braces effective for treating bite problems. In those studies, aligners did better at moving segments of teeth and had shorter treatment times. Braces did better at getting the back teeth to meet well, controlling root angle (torque), widening the arch and keeping results stable. The authors noted that the evidence base was small, so your provider’s assessment of your own case matters more than averages.

Daily life with each

Wear time. Braces work all the time because they stay on. Aligners only work while they are in your mouth, so results depend on wearing them about 22 hours a day, every day (AAO).
Eating. Aligners come out to eat and drink anything other than water, then go back in after you brush (AAO). With braces you eat with them on, and the ADA suggests avoiding sticky and hard foods such as popcorn, chewing gum, corn on the cob and whole apples.
Cleaning. Aligners come out for brushing and flossing. Braces need more care around the brackets, because plaque that builds up there can stain or damage the teeth (ADA).
Looks. Aligners are hard to see. Tooth-colored or behind-the-teeth braces are less visible than metal ones.
Visits. Both need regular check-ups. With braces the wire is adjusted at visits; with aligners you get new sets of trays and progress checks.

How long treatment takes

The ADA says most people are in orthodontic treatment for one to three years, followed by a retainer. Aligners are not automatically faster: the AAO points out that the trays are usually made off site and can take four to six weeks to arrive, and scans and attachments come first. In the 2019 review, aligner cases were shorter on average, but those were often milder cases. Ask your provider for an estimate for your own teeth.

Age: children, teens and adults

The AAO recommends a first orthodontic check for children around age 7, when an orthodontist can spot problems with the jaw or the incoming adult teeth. The ADA says treatment often starts between ages 8 and 14, while the jaw is still growing, but healthy teeth can be moved at any age. Many adults choose aligners because they are hard to see; braces remain an option for adults too.

Cost and insurance

We do not list prices, because they depend on the case and the office. The total for either option depends on how complex the movement is, how long treatment lasts, extra aligners (refinements) if the teeth do not follow the plan, retainers and follow-up visits. The AAO says dental plans with orthodontic coverage usually cover braces and clear aligners equally, but plans vary. Its retainer guidance adds that the first retainers are often part of the treatment fee, while replacements may cost extra. Ask for the full cost from the first scan to the final retainer.

After treatment: retainers

Teeth tend to drift back. The AAO says everyone who finishes orthodontic treatment should wear a retainer as prescribed, whether they had braces or aligners. Retainers can be clear plastic, or wire and acrylic, and some are bonded behind the teeth. Ask how long and how often you will need to wear yours.

Questions to ask at the consultation

Which option do you recommend for my teeth, and why not the other one?
Is my case something aligners handle predictably, or would braces do a better job?
Who plans my treatment and who checks my progress: an orthodontist or a general dentist?
What happens if my teeth do not follow the aligner plan? Are extra aligners included?
How long do you expect treatment to take for me, with each option?
What does the price include: scans, attachments, refinements, retainers, visits?
Does my insurance cover orthodontics for adults, and is there a payment plan?

Frequently asked questions

Is Invisalign better than braces?

Neither is better for everyone. Both can treat many cases. A 2019 systematic review found braces more effective for some movements, such as controlling root angle and getting the back teeth to meet well, while aligners did well for moving segments of teeth. Your orthodontist decides which fits your case.

Is Invisalign faster than braces?

Not necessarily. The aligners are usually made off site and can take weeks to arrive, and results depend on wearing them about 22 hours a day. Most orthodontic treatment takes one to three years, then a retainer.

Can adults get braces or aligners?

Yes. The ADA says healthy teeth can be moved at any age, and many adults are treated with either braces or aligners.

Does insurance cover clear aligners?

If your dental plan has orthodontic coverage, the AAO says it usually covers aligners and braces equally. Plans differ, so check your own plan before treatment.

Do I need a retainer after aligners?

Yes. The AAO says everyone should wear a retainer after orthodontic treatment, with braces or with aligners, to keep the teeth from moving back.
