Invisalign vs braces: which costs less in 2026?

Clear aligners such as Invisalign cost $4,500–9,000 at a private practice in Australia, $4,700–9,560 in New Zealand, £1,900–4,500 in the UK, $3,000–5,000 in the US and $3,000–8,500 in Canada. Fixed metal braces are $6,000–9,000, $5,000–9,500, £1,500–5,000, $3,000–7,500 and $3,000–7,000 in the same countries. The two ranges overlap in every country, so the real question is not which product is cheaper but which is cheaper for your teeth: braces are usually the lower quote for a simple case, and aligners are usually the higher quote for a complex one.

Clear aligners: the published range

These are full-treatment fees from orthodontists and dentists who publish their prices, not the "from" figure on a mail-order aligner website. The Clear aligner / Invisalign cost calculator starts at the midpoint for your country and lets you add retainers, a scan and any insurance benefit.

Metal braces: the published range

The braces range is wider than the aligner range in several countries because it stretches from a short, simple case in a general practice to a long, complex case with a specialist. The Braces cost calculator works the same way as the aligner calculator so you can put the two quotes side by side.

What each fee should include

A proper orthodontic quote is for the whole course, not per visit. It should name:

• Records. Photographs, x-rays and a digital scan or impressions. Some practices charge these as a separate consultation fee.
• The appliance. Every aligner tray in the series, or the brackets, wires and bands, including replacements for lost trays or broken brackets up to a stated number.
• Adjustments. Aligner reviews every six to ten weeks, or brace tightening every six to eight weeks, for the planned length of treatment.
• Refinements. Aligner cases often need a second round of trays at the end to finish small movements. Ask whether refinements are included and how many.
• Retainers. See below. This is the item most often left out.

If a quote is well under the low end of your country's range, it is probably a limited "front six teeth" treatment or excludes records and retainers.

Retainers: the cost after the cost

Teeth drift back towards their old positions after any orthodontic treatment. Every orthodontist will fit a retainer when the appliance comes off, and most now recommend wearing a removable retainer at night for as long as you want the teeth to stay straight, which in practice means indefinitely.

There are two kinds. A bonded retainer is a thin wire glued behind the front teeth; it needs nothing from you but can break and must be checked. A removable retainer is a clear plastic tray or a wire-and-acrylic plate; it wears out and gets lost, so plan on replacing it every few years. Ask what a replacement set costs before you sign, because that is a recurring bill for the rest of your life, and it is the same whether you chose aligners or braces.

How long each takes

Aligner treatment for a mild to moderate case typically runs twelve to eighteen months, with simple cases finishing in six and complex cases taking two years. Fixed braces typically run eighteen to twenty-four months, with complex cases up to three years. The difference is smaller than the marketing suggests, and it comes mostly from the cases each option is used for rather than from the appliance itself.

Length matters for cost in two ways. Longer treatment means more visits, which some practices charge for beyond the quoted term. And with aligners, the fee depends on compliance: trays must be worn about twenty-two hours a day, and a case that stalls because they were not worn ends with extra refinement trays and extra months.

Which suits which cases

• Aligners suit mild to moderate crowding or spacing, relapse after earlier braces, and adults who want a removable, near-invisible appliance and are disciplined enough to wear it.
• Braces suit severe crowding, large bite corrections, rotated or impacted teeth, cases needing extractions, and children and teenagers who cannot be relied on to wear trays. Braces work all day whether you remember them or not.
• Either works for a large middle group. If your orthodontist offers both for your case, the choice is about appearance, hygiene and habit, and the quotes are usually close.

Ceramic (tooth-coloured) braces and lingual braces fitted behind the teeth cost more than metal and are not in the ranges above.

What insurance and public schemes pay

Orthodontics is treated differently from other dentistry almost everywhere: benefits are a fixed lifetime amount, waiting periods are long, and public funding for adults is close to nil.

• Australia: Medicare pays nothing. Extras policies that include orthodontics pay a set amount that accrues each year up to a lifetime limit, most commonly between about $1,000 and $2,800, after a waiting period that is twelve months at almost every fund. The lifetime limit follows you if you switch funds. Orthodontics is usually only on mid- to top-tier extras.
• New Zealand: Free dental care for under-18s does not include orthodontics. Publicly funded treatment is limited to hospital cases such as cleft lip and palate and severe jaw discrepancies needing surgery; fewer than one in a hundred cases qualify. Insurer dental add-ons rarely cover it.
• UK: NHS orthodontics is for under-18s with a definite clinical need, assessed on the Index of Orthodontic Treatment Need, and is free for them. Adults are approved only case by case for severe functional problems, so adult treatment is effectively private. Most private dental plans exclude orthodontics.
• US: Dental plans with orthodontic benefits typically pay around 50% of the fee up to a lifetime maximum of roughly $1,000 to $3,000 per person, which does not reset. Coverage favours children; adult orthodontics often needs a rider or a higher-tier plan, and waiting periods of six to twelve months are common. An FSA or HSA can pay the balance pre-tax.
• Canada: The Canadian Dental Care Plan states that orthodontic services are currently not available; if they are added they are expected to be limited to severe, functionally handicapping cases and craniofacial anomalies. Employer plans that include orthodontics work like US plans, with a percentage and a lifetime maximum.

Before you compare quotes, get the lifetime limit and the waiting period in writing from your insurer and enter that figure, not the brochure's percentage, into the calculator.

Paying over time

Because the fee is spread across a year or two of visits, most orthodontists offer an interest-free payment plan with a deposit and monthly instalments over the length of treatment, and that is usually cheaper than borrowing. If you do finance it, the Dental finance repayment calculator shows the monthly repayment and the total interest for a given rate and term, so you can see whether a longer plan is worth its cost. Put the practice's plan and a loan side by side rather than assuming one is better.

What to do next

1. Ask the orthodontist to quote aligners and braces for your case as a complete course, listing records, refinements and the first set of retainers.
2. Run both quotes through the Clear aligner / Invisalign cost calculator and the Braces cost calculator with your insurer's written lifetime limit to compare the out-of-pocket totals.
3. If the practice offers an in-house plan, compare it with the Dental finance repayment calculator before signing anything with interest.
