What a retainer costs
in New Zealand, and when it is free.
Published NZ price guides put a clear removable retainer at about $200 to $600 and a bonded wire at about $250 to $500 per arch. At Milk, retainers are part of the treatment fee, a replacement is complimentary in the first year if one breaks or wears out, and a lost retainer is quoted before anything is made. If you were treated somewhere else, we make three sets of clear removable retainers: $595 for one arch or $895 for both.

Why the cheap option costs more
A retainer only works if it fits exactly. Three ways the saving disappears.
Made to drifted teeth
If teeth have already moved, a retainer made to them locks the drift in. A specialist checks first.
A fit nobody checked
Home impressions distort. A retainer that rocks or gaps lets the front teeth move within weeks.
Re-treatment
Once teeth have relapsed, the fix is treatment again, not a retainer. That is the real cost of a $150 saving.
How replacement works
Book now, not next month
Teeth drift fastest in the first year after treatment. Wear an older retainer or final aligner at night in the meantime if one still fits.
A quick check and a scan
We check whether anything has moved, then take a digital scan. No impressions.
The price, confirmed first
You know the exact cost before the retainer is made.
Fitted and checked
Removable retainers are fitted and checked. For Milk patients, a bonded wire is re-bonded where possible. Night wear from then on.
Everything about retainer types and wear is in the complete retainer guide. Caring for one: cleaning and storage.
Answered honestly
How much does a retainer cost in NZ?
Published NZ guides put a clear removable retainer at about $200 to $600 and a bonded wire at about $250 to $500 per arch. If you are treated at Milk, your retainers are included in the treatment fee, replacements are complimentary in the first year if one breaks or wears out, and a lost retainer is quoted before anything is made. For people treated elsewhere, three sets of clear removable retainers cost $595 for one arch or $895 for both.
Are retainers included in the cost of braces at Milk?
Yes. Retainers at the end of treatment and the aftercare checks are part of the all-inclusive fee. Nothing is added when the braces come off.
How much is a replacement retainer if I lost mine?
It depends on the type and whether we still hold a recent scan of the teeth. The price is confirmed before anything is made, and it is a small fraction of orthodontic treatment. Book promptly: teeth drift most in the first year after treatment.
Can I get a retainer if I had braces somewhere else?
Yes, a removable one. We make clear removable retainers for people treated at another clinic or overseas, or whose orthodontist has retired: three sets from one digital scan, $595 for one arch or $895 for both. We do not fit, repair or replace fixed wires for people treated at another practice. For a fixed wire, please see the orthodontist who treated you, or your dentist.
Removable or bonded, which is cheaper?
A clear removable retainer is usually cheaper to make. A bonded wire costs more to fit because it is placed and checked in the chair, but it works around the clock without anyone remembering it. Many people have both: a wire behind the lower front teeth and a clear retainer at night.
Why not buy a retainer online?
An online retainer is made from a home impression with nobody checking the fit or the bite. A retainer that does not fit exactly lets teeth move, and a retainer made to teeth that have already drifted locks in the drift. The saving is small and the risk is the whole result.
How long do retainers last?
A clear removable retainer typically lasts a year or two with night wear before it clouds or cracks. A bonded wire can last many years but should be checked. Plan on retainers for life, worn at night, whatever the age.
Do I need to see an orthodontist for a replacement, or will a dentist do?
Either can make one. If you were treated at Milk, we check whether the teeth have moved and can re-bond a fixed wire. If you were treated elsewhere, we make removable retainers to fit your teeth as they are today, and the practice that fitted a fixed wire, or your dentist, looks after it. If anything has drifted, we say so and tell you the options honestly.
