Braces vs Aligners: Which Is Right for You?

If you are weighing braces vs aligners, the research gives a fairly clear answer. Both can straighten teeth well when the problem is mild to moderate. Fixed braces stay the more reliable choice for harder cases. The right option for you depends on your bite, your lifestyle and how disciplined you can be with removable trays. This braces vs aligners guide sets out what the evidence shows, where it is weak, and what to ask at your consultation.

Braces vs aligners at a glance

• Mild to moderate problems, no tooth removal needed: results are broadly similar, according to two systematic reviews published in 2024 and 2025 [1][2].
• Complex cases and cases that need extractions: fixed braces give better control and a better-quality finish [2][3].
• Early comfort: aligners cause less pain in the first days, with moderate-certainty evidence [4].
• Cleaning and gum health: aligners come out for brushing, and research links them to less plaque and fewer white spots. The evidence on gum health is mixed [5][6].
• Speech: fixed braces were better for speech during treatment in one major review [1].
• Discipline: aligners only work if you wear them most of the day, around 22 hours [7].
• Cost: clinic prices in Nigeria for aligners vary enormously, so always get a written quote.

What is the difference between fixed braces and clear aligners?

Fixed braces are brackets glued to the teeth and joined by a wire. Cleveland Clinic describes traditional braces as moving “your teeth with metal or ceramic brackets and an orthodontic wire” [7]. Your orthodontist or dentist tightens them at regular visits. If you want the full explanation of how they work and the different types, read our guide to braces on teeth.

Clear aligners are “clear, custom-made plastic devices that fix crowded or crooked teeth”. They look like trays that fit over your teeth. You swap to a new set about every two weeks, and you take them out to eat, drink and clean your teeth [7]. Each tray is shaped slightly differently from the last, so each one presses the teeth a small step further.

Brand names vs the general term. “Clear aligners” is the general name for the treatment. Invisalign and ClearCorrect are brand names [7]. Ask your clinic which system it uses and why.

Braces vs aligners: which works better?

Honest answer: for simple cases, about the same. For difficult cases, braces.

A 2024 systematic review by Baneshi and colleagues found that aligners were “not significantly more effective than fixed appliances for simple malocclusions treated on nonextraction basis”. The same review noted that “the quality of randomised controlled trials on clear aligners is low” [1]. A 2025 review in the European Journal of Orthodontics reached a similar conclusion. It found no significant difference in treatment quality or duration in non-extraction cases. In extraction cases, “fixed appliances provided superior treatment quality” [2].

A 2023 review of complicated and severe cases found that both treatments worked in premolar-extraction cases, but that “the duration of treatment was shorter with fixed appliances” [3].

By type of problem

• Mild crowding and small gaps (no extractions): aligners and braces are broadly comparable [1][2].
• Rotated teeth: a 2025 review of adult front-tooth movement concluded that fixed braces appear to give better control of rotation and torque. The authors describe this as limited evidence from a small number of studies [8].
• Severe crowding or extraction cases: fixed braces give a better-quality finish [2]. The British Orthodontic Society (BOS) says that in severe cases, “notably those where extractions are required, aligners lack the necessary control” [9].
• Prominent upper front teeth: the BOS says aligners “are not well suited to correcting problems like prominent upper incisor teeth” [9].
• Overbite, underbite, crossbite and open bite: we did not find a review that compares braces vs aligners for each of these separately. So the fair summary of braces vs aligners for these problems is that evidence for complex bite problems is limited, and fixed braces give more control. Be wary of any clinic page that promises aligners fix every bite problem. That is marketing, not evidence.

What the studies actually measured. The 2024 review found quality of life was better with aligners at six months [1]. Commentary on the 2025 review reported that in extraction cases, scores on the American Board of Orthodontics scale were higher in the fixed braces group (mean difference 2.76, 95% CI 0.41 to 5.12). The commentator rated the quality of that evidence as low and doubted the difference is clinically significant. The review authors concluded that aligners “may achieve comparable treatment outcomes” in mild to moderate non-extraction cases, but that “fixed appliances demonstrate superior control for complex cases and have a higher standard of finish” [24]. On what happens after treatment, the 2025 review found only “limited evidence” that results stay similarly stable [2].

How strong is the evidence? Weak to moderate. The 2024 review describes the quality of randomised trials on clear aligners as low [1], the 2025 review found limited evidence on stability [2], and the review of front-tooth movement rests on a small number of studies [8]. The honest summary is that the evidence points in a consistent direction, but it is not strong enough to be certain, so your own examination matters more than any general rule.

Braces vs aligners: how long does treatment take, and how many visits?

In non-extraction cases, the 2025 review found no significant difference in treatment duration between the two, although sensitivity analyses suggested shorter treatment with aligners [2]. In extraction cases, the 2023 review found fixed braces were quicker [3].

For fixed braces, Cleveland Clinic gives an average of about two years, and says some people need as long as three [10]. For aligners, it says a few slightly crooked teeth may take up to nine months, with several more months for more serious problems [7].

Visits for braces: the NHS says to expect “an appointment with the orthodontist every 6 to 8 weeks” [11], while the BOS says “every four to ten weeks” [9]. The two ranges differ a little, so ask your own clinic for its schedule. Claims online that aligners mean half as many visits come from clinic marketing, not research, so we do not repeat them.

Which hurts more: braces vs aligners?

Both cause some discomfort. A systematic review in Progress in Orthodontics found, “based on a moderate level of certainty”, that Invisalign patients “appear to feel lower levels of pain than those treated with fixed appliances during the first few days of treatment”. The differences disappeared after that [4]. A 2023 review in BMC Oral Health found less pain with aligners on days 3 and 4 and better oral-health-related quality of life [12]. A 2026 meta-analysis in BDJ Open reached a similar conclusion [13].

Speech. This one favours braces. The 2024 Baneshi review reported that “fixed appliances were better for speech during orthodontic treatment” [1]. If you speak for a living, raise this at your consultation.

Eating. With aligners you take the trays out for meals. With braces you follow food rules: the NHS advises not eating hard, crunchy or sticky foods and not chewing gum [11]. An observational study of 160 patients found fixed braces linked with a higher dietary impact and more painkiller use than aligners [14]. That was an observational study, so treat it as a pointer rather than proof.

Sore spots. The American Association of Orthodontists (AAO) lists sore spots, mouth sores and poking or loose wires among the problems to report [15]. We found no review that directly compares ulcer rates between the two. Aligners have no wires or brackets to rub, but that is a design point, not a measured result.

Braces vs aligners for oral hygiene and gum health

A 2023 systematic review in BMC Oral Health by Raghavan and colleagues pooled 5 randomised trials and 9 non-randomised studies. It found moderate-quality evidence of less plaque and fewer caries-associated bacteria with aligners, which might be related to fewer white spot lesions compared with fixed braces. The authors cautioned that some of the studies had a high risk of bias [5][16]. White spots are early signs of tooth decay.

A 2026 review in BDJ Open found better plaque and gum scores with aligners [13]. However, an umbrella review of earlier reviews concluded that the effect on gum health “should be considered comparable” [6]. So the honest message is that aligners are easier to clean around and may be kinder to the gums, but good brushing matters with both.

One caution for aligners: the AAO has warned that decalcification “may occur or accelerate during use of aligners” [17]. Wearing trays over unbrushed teeth holds sugar against the enamel. Brush before you put them back in.

Wear time: the part aligners cannot skip

Aligners only work if you wear them. Cleveland Clinic recommends “22 to 23 hours every day” [7]. The BOS says aligners “need to be worn full-time, day and night except for meal times” [18].

A 50-patient randomised trial, discussed in an orthodontic academic’s blog, compared 12 and 22 hours of daily wear in very mild crowding. Both groups improved, but the lower front teeth corrected 0.84 mm more with the 22-hour protocol [19]. In a survey of aligner patients, 53.7% reported wearing them 20 to 22 hours a day. The paper notes that self-reported wear tends to be overestimated, citing a study that found a gap of 5.02 hours a day between reported and measured wear of removable appliances [20]. That survey was self-reported, so treat it with care.

If you know you will leave trays in your bag, fixed braces may suit you better. They work whether you remember them or not.

What about teenagers?

The BOS describes aligners as “ideally suited to adult patients whose life-style or work commitments make it difficult for them to wear more visible conventional fixed appliances” [18]. For teenagers, the question is mostly about maturity and supervision. A teenager has to wear the trays for most of the day, and a parent usually has to help check that they do. Statistics you may see online about most teenagers failing to wear their trays long enough come from clinic marketing pages, so we do not use them. Whether aligners suit your teenager is a clinical decision. Our guide to braces for kids covers the age question in more detail.

Retainers: needed with both

The Cochrane Library review on retention says “almost every person who has orthodontic treatment will require some type of retention” to limit relapse. It also found no moderate- or high-certainty evidence that favours any one retention method [21]. The BOS adds that after any aligner treatment, retainers will be required [18].

Be careful with remote and do-it-yourself aligners

Some companies sell aligners directly to the public with little or no in-person check-up. Regulators and professional bodies have warned about this.

• The UK’s General Dental Council said such services “fall within the legal definition of dentistry so can only be performed by dentists and dental care professionals who are registered with the GDC”. It added: “At present, there is no effective substitute for a physical, clinical examination” [22].
• In 2026, the US Food and Drug Administration (FDA) said it has not authorized clear aligners sold directly to consumers without a prescription and professional supervision. It reported cases of “new or worsening dental pain, jaw pain, bite problems, worsening tooth misalignment and new gaps between teeth”. It also noted that “FDA-registered” is not the same as “FDA-authorized” [23].
• The British Orthodontic Society said its members “have long warned of concerns about direct-to-consumer orthodontics” [22].

Whatever you choose, make sure a registered dentist or orthodontist examines you first and supervises your treatment. You can check registration with MDCN.

Clear aligners cost in Nigeria

Clear aligners cost in Nigeria varies from clinic to clinic, and published prices are inconsistent, so we do not quote other clinics’ figures here. The British Orthodontic Society notes that the cost of aligners can be higher than for conventional fixed braces because of the laboratory costs of making them [9].

Ask The Dentist’s current clear aligner price: [CLIENT TO CONFIRM: price or range, and what it includes].

When you compare quotes from any clinic, ask for a written quote and check that it states:

• how many aligner sets (trays) are included, and whether refinements are covered
• whether the consultation, X-rays or scans are included
• whether retainers are included, since you will need them after any aligner treatment [18]
• what happens if treatment takes longer than planned

How to choose in the braces vs aligners decision

Fixed braces are usually better suited to:

• severe crowding or cases that need extractions [2][9]
• prominent upper front teeth [9]
• large rotations and root control [8]
• people who may not wear removable trays full-time [7][18]
• people whose speech matters a lot for work [1]

Clear aligners are usually better suited to:

• mild to moderate crowding or spacing without extractions [1][2][18]
• adults who want a discreet option [18]
• people who clean carefully and want easier brushing and flossing [5][13]
• people who want less discomfort in the first week [4]

These are general guides to the braces vs aligners choice. Only an examination, X-rays and a treatment plan can tell you what fits your own mouth.

Questions to ask before you decide

Whichever side of the braces vs aligners choice you lean towards, take these questions to your consultation:

• Is my case mild, moderate or complex, and does it need extractions?
• Which option gives the best control for my particular bite?
• Who will supervise my treatment, and how often will I be seen?
• How many hours a day will I need to wear aligners, and what happens if I fall short?
• What is the total price, and does it include retainers and any refinements?
• Which aligner system is used, and why?
• How will I be protected after treatment, and what retainer plan do you recommend?

What the evidence cannot tell us

It helps to be clear about the gaps. The reviews above describe the quality of aligner trials as low [1], with limited evidence on how well results hold up afterwards [2]. That does not mean aligners are unsafe or ineffective. It means a proper examination and a clear treatment plan from a registered dentist or orthodontist matter even more.

A note on terms

In everyday Nigerian speech, “braces” means fixed brackets and wires, and some clinics say “invisible braces” for aligners. In this guide we say “fixed braces” for brackets and wire and “clear aligners” for removable trays. Invisalign is one brand of clear aligner, not the general word.

Frequently asked questions

Are aligners as good as braces? For mild to moderate problems that do not need extractions, reviews find no significant difference in results [1][2]. For complex cases, fixed braces give better control [2][3].

Do aligners hurt less than braces? In the first few days, yes, with moderate-certainty evidence. After that the difference disappears [4].

Can I take my aligners out whenever I like? No. You need to wear them about 22 hours a day, removing them only to eat, drink and clean [7].

Do I still need a retainer after treatment? Yes. Almost everyone needs some form of retention after braces or aligners [21][18].

Are online-only aligners safe? Regulators in the UK and the US have warned about direct-to-consumer aligners without proper supervision [22][23]. See a registered dentist first.
