If your retainer is lost, cracked, or sitting in a napkin in a restaurant dumpster somewhere, the clock matters more than the cost.
Teeth start drifting back within days of stopping retainer wear, not months. So the useful question is not “how much is a new one,” it is “what do I do tonight, and how fast can I get a replacement.”
What to do in the first 48 hours
Call an orthodontist and get on the schedule for a scan. That is the whole answer, and speed is the reason.
The teeth that move first are the ones that were rotated or crowded before treatment, because they carry the most memory. A few days of no retainer usually costs you nothing. A few weeks can mean the replacement no longer seats properly, which turns a simple remake into a conversation about limited retreatment.
In the meantime:
- If you still have the retainer and it is only cracked, keep it and keep wearing it if it goes in without force. A cracked retainer that still seats is better than nothing while you wait.
- If it is warped from heat, stop wearing it. A warped retainer actively pushes teeth in directions nobody planned.
- Do not try to repair it yourself. Glue is not safe in the mouth and a home repair changes the fit in ways you cannot see.
- Do not order a mail order replacement from an impression kit if your teeth have already moved, because you will be locking in the drift rather than reversing it.
Can it be repaired, or does it need remaking?
Usually remade. It depends on which kind you have and what happened to it.
A Hawley retainer, the kind with the wire across the front and an acrylic body, can sometimes be repaired if the acrylic cracked but the wire is intact and undistorted. Clear plastic retainers generally cannot be repaired. Once they crack, split, or warp, the geometry that made them fit is gone, and a new one has to be made. A bonded retainer behind the teeth is a different situation: if a section of wire comes loose from a tooth, that often can be re bonded rather than replaced, and it should be looked at quickly because a partly attached wire lets some teeth move while holding others.
The bonded case deserves its own note, because it is the one people ignore longest. A fixed wire that has come off one tooth still looks fine in the mirror and still feels attached, so it gets left for months. Meanwhile the teeth it is no longer holding are free to move while the ones still bonded stay put, which produces exactly the uneven shift it was placed to prevent. If you can floss under a section that used to be solid, get it looked at. Our guide to permanent retainers on the bottom teeth goes into how they fail and what to watch for.
Bring whatever you have left, even in pieces. It tells us what type you had and how it was designed.
REPLACEMENT RETAINERS
Lost it? Get scanned before your teeth move.
We use a 3D scanner rather than the old putty impressions, and most replacement retainers run $150 to $300 depending on type. Costs are gone over upfront, with no surprise line items later.
What a replacement retainer costs
At our Cary office most replacement retainers run $150 to $300, depending on which type you need. We go over the cost upfront and check whether your insurance contributes anything, which some plans do and many do not.
Two things that change the number: which retainer you had, since clear and Hawley are priced differently, and whether you need one arch or both. If you have lost the top and the bottom, ask about doing both at once rather than as two separate visits.
If you want the fuller picture on retainer pricing generally, including first sets and permanent retainers, our guide to retainer cost covers all the types.
Do you have to be an existing patient?
No. Plenty of the replacement retainers we make are for people who had braces somewhere else, sometimes years ago and in another state.
You do not need your old records, and you do not need to have been treated here. What we need is a current scan of your teeth as they are today, which takes a few minutes. If your teeth have shifted since your original treatment, we will tell you that honestly rather than making a retainer that fights your bite.
That honesty matters more than it sounds. A retainer built over teeth that have already drifted will hold them in the drifted position, which is not what anyone is paying for. When the movement is small, a new retainer is still the right call. When it is not, the real options are living with the current position or a short course of limited treatment to bring things back before retaining. Either way you should hear which situation you are in before you pay for anything.
Why the scan matters more than the old mold
A replacement retainer is built to fit the teeth you have now, not the teeth you had when treatment finished.
This is the part people find counterintuitive. Patients often ask whether we can just make a new one from their old records. Usually that is the wrong move, because if the teeth have drifted even slightly, a retainer built to the old position will not seat, or it will seat under pressure and feel wrong every night. We scan fresh so the appliance matches reality.
We use 3D scanning rather than putty impressions, which for most people is the difference between a two minute pass with a wand and a mouthful of material.
How to not be here again
Three habits account for most of the retainers we replace.
- The napkin. Retainers wrapped in a napkin at a restaurant get thrown away, reliably, every single time. Case or pocket, never a napkin.
- The car and the dishwasher. Heat warps clear retainers. A dashboard in a Carolina July will finish one off in an afternoon, and so will the top rack of a dishwasher.
- The dog. Retainers smell like their owner, and dogs find them irresistible. Store the case somewhere with a closed door.
Worth considering: a backup set made at the same time as the replacement. It costs less than going through this twice, and it is the single most useful thing to ask about while you are already in the chair.

Frequently Asked Questions
How much is a replacement retainer?
Most run $150 to $300 at our Cary office, depending on the type and whether you need one arch or both.
How fast do teeth move without a retainer?
Faster than most people expect. Movement can begin within days, and it is most noticeable in teeth that were rotated or crowded before treatment. That is why the priority after losing one is getting scanned quickly rather than shopping around for a week.
Can I get a replacement retainer if I had braces somewhere else?
Yes. You do not need your old records or any prior relationship with our office. We scan your teeth as they are now and make the retainer from that.
Can a broken retainer be fixed instead of replaced?
Sometimes, and it depends on the type. Hawley retainers with cracked acrylic and an intact wire can occasionally be repaired. Clear plastic retainers generally cannot, because once the plastic cracks or warps the fit is gone. A loose bonded retainer behind the teeth can often be re bonded rather than replaced, and that one is worth getting seen quickly.
My retainer feels tight after not wearing it for a while. Should I force it?
No. Tightness means your teeth have moved. Forcing it can crack the retainer or move teeth in an uncontrolled way. Bring it in and let someone look at whether it still fits or whether you need a new one.
Do I need a retainer forever?
Some form of retention is generally lifelong, though wear usually tapers from full time to nights only over the first year or so. Teeth keep a memory of where they were, and relapse is possible at any age without retention. Your specific schedule is something Dr. Patel sets based on your case.
The short version
Get scanned quickly, keep wearing a cracked retainer if it still seats, stop wearing a warped one, do not glue anything, and expect $150 to $300 for most replacements. You do not need to have been treated here.
