Short answer: When a retainer is lost or broken, your teeth will not return to their old position overnight, but every day without a retainer raises the chance of shifting, especially if your treatment ended recently. The first thing to do is let your orthodontist know and book an appointment soon. A new retainer is made after your teeth are assessed and scanned or an impression is taken; if shifting has started, your options are determined at the exam.
A retainer wrapped in a napkin at a restaurant, lost in a travel bag or turned into the family pet's new toy is a story orthodontic clinics hear often. The short answer to "I lost my retainer, will my teeth get messed up now?" is this: your teeth will not return to their old position overnight, but every day without a retainer raises the chance of shifting. Whether the retainer is broken, cracked or simply gone, the thing to do is the same: let your orthodontist know without delay. In this article we walk you through the first steps, when shifting can begin and how a new retainer is made.
The first step when a retainer is lost
When a retainer is lost, the first step is to call your clinic and book an appointment for a new retainer as soon as possible. Waiting, or putting it off because "my teeth still look fine," can make the process harder later.
- Do one last search: Think about where you last used the retainer case. Retainers taken out after a meal are often thrown away with the napkin, and pets may pick up a retainer like a toy because of its smell.
- If you have a spare, wear it right away: If you have a previous retainer or the last clear aligner from your treatment, asking your doctor about wearing it temporarily may help support your teeth.
- Contact the clinic: Tell them when you lost the retainer and whether you have noticed any change in your teeth.
- Check your bonded wire if you have one: If you use both a fixed and a removable retainer, make sure the bonded wire is intact.

How soon can shifting begin?
When shifting starts varies from person to person. If treatment ended recently, changes may be noticeable within days or a few weeks, whereas the process is usually slower when treatment was completed years ago. The reason is that the connective tissue around the teeth needs time to adapt to their new position.
The answer to "what happens if I don't wear my retainer?" depends on this as well. The tendency of teeth to move back toward their old positions is stronger in the first months. It can be more pronounced in people who started with marked crowding, gaps or rotated teeth. Teeth also keep moving slightly throughout life because of chewing, tongue pressure and age-related changes, which is why a retainer is recommended as a long-term habit for most patients.
- If your retainer feels tight when you try to put it in, your teeth may have moved a little.
- If you notice new overlap or a new gap in the front teeth, make a note of it.
- If your teeth seem to touch differently when you bite, mention it at your appointment.
Can you wear a broken or cracked retainer?
It is not recommended to keep wearing a broken or cracked retainer on your own; it is safest to ask your doctor whether to use it until it has been examined. A small crack can reduce the retainer's hold on your teeth, and sharp edges can irritate the tongue or cheek. A larger break may cause the retainer to apply the wrong force to your teeth.
In some cases, your doctor may consider it acceptable to use a slightly cracked retainer for a short time until the new one is ready; this decision depends on the type of retainer and where the damage is. Do not try to glue broken pieces together. Materials that are not meant for use in the mouth irritate the tissues and also spoil the fit of the retainer. Bringing the retainer to your appointment in its case makes the assessment easier.
How is a new retainer made?
A new retainer is made after the current state of your teeth has been assessed, using an intraoral scan or an impression. The process of getting a replacement retainer usually involves these steps:
- Exam: The doctor checks the alignment of your teeth and your bite, and compares them with your end-of-treatment records.
- Scan or impression: If your teeth are still in the intended position, the new retainer is planned from a current scan.
- Fabrication: The clear retainer is made to match the scan. Preparation time varies depending on the method used.
- Delivery and fit check: The retainer is tried in your mouth, and its fit and edges are checked; wear instructions are explained again.
For detailed information on wearing and caring for a clear retainer, see our page on the retainer after clear aligners. For general information on retainer types and the protection phase after treatment, you can read our article on retainers and keeping your teeth in place after orthodontic treatment. Fee information for a new retainer is provided in writing after the exam and planning.
Why is a spare retainer useful?
A spare retainer is a practical safeguard for many patients because it keeps the teeth from being unprotected when a retainer is lost or broken. If you have a second set when you find your clear retainer missing, the time until the new one is ready is not a risk.
- The chance of loss rises during travel and busy periods; a spare retainer gives peace of mind at those times.
- It helps to have the spare checked at the intervals your doctor recommends, to make sure it still fits the current position of your teeth.
- Keep the spare retainer in its own case, away from sunlight and heat; hot water and a hot car interior can distort a clear retainer.
You can talk with your doctor about whether you would like a spare retainer at the end of treatment or at your check-ups.
Small habits that prevent loss
Most retainer losses happen in the few minutes after it has been taken out of the mouth. A few simple habits reduce this risk noticeably:
- When you take the retainer out, always put it in its own case, not in a napkin or your pocket.
- Choosing a bright, easy-to-spot case makes it less likely to be left behind on a table.
- At home, keep the retainer where pets cannot reach it.
- Tie putting it in at bedtime and taking it out and cleaning it in the morning to something in your daily routine, such as right after brushing your teeth.
Options if shifting has started
If shifting has started, the options range from a light realignment to a new orthodontic plan, depending on the degree of change. Noticing the shift early generally makes it possible to proceed with a simpler solution.
Minor changes
If there has been only slight movement, your doctor may consider making the new retainer to match the current position of your teeth, or making a small correction with a few clear aligners. At our clinic, clear aligner treatment is provided with Invisalign; whether a short correction like this is suitable is determined at the exam.
Noticeable changes
If the shift is noticeable, new orthodontic treatment may need to be planned. In that case, the duration and method are determined by the doctor according to the state of your teeth and bite. If you use a bonded retainer and the wire has come loose as well, our article on what to do when a bonded retainer comes off can guide you.

Frequently asked questions
I lost my retainer. Will my teeth get messed up if I skip it for a few days?
A noticeable change does not always happen within a few days, but if treatment ended recently, shifting can begin more quickly. For this reason, we recommend letting your clinic know as soon as possible.
Can I use my old clear aligner instead of a retainer?
The last aligner from treatment can provide temporary support in some cases, but not every aligner works as a retainer. You should ask your doctor before using it.
Can I keep wearing a cracked retainer?
It depends on where the crack is and the type of retainer. We do not recommend continuing to use it before your doctor has seen it; do not glue broken pieces together yourself.
How long does it take to make a new retainer?
The time varies depending on the scanning and fabrication method used. After your teeth are assessed at the exam, you are given the timing and fee information in writing.
How long do I need to wear a retainer?
How long you need to wear a retainer varies from person to person and is determined by your doctor. Because teeth can move slightly throughout life, long-term use, usually at night, is recommended for many patients.
