What is a permanent retainer?
A permanent retainer, also called a fixed or bonded retainer, is a thin steel wire glued with dental adhesive to the tongue side of the teeth. It is most often placed on the lower front six teeth, where relapse is most common, and sometimes on the upper front teeth. It is not visible from the front.
It works around the clock without any effort from you, which is its biggest advantage. The cost depends on the type and number of teeth; see the retainer cost page for general market ranges. For the wider picture of why retainers are needed at all, read our guide on retainers after braces, and see braces and orthodontics for the treatment itself.
Clear retainer vs removable retainer vs permanent retainer
A clear retainer is a thin, transparent plastic tray that fits over the teeth, worn mostly at night. A removable retainer in the traditional sense is a Hawley type, with an acrylic plate and a wire across the front teeth. Both come out for eating and cleaning, which makes brushing and flossing easier, but they only work if you wear them. They can also be lost, cracked or left behind.
A permanent retainer holds only the teeth it is bonded to, usually the front ones. Many orthodontists combine a fixed wire on the lower front teeth with a removable retainer for the upper arch. The right mix depends on your case.
| Feature | Permanent retainer | Clear retainer | Removable (Hawley) retainer |
|---|---|---|---|
| Worn how | Bonded in place all the time | Taken in and out, mostly at night | Taken in and out, full time at first then nights |
| Visible | Barely | Almost invisible | Wire and plate may show |
| Cleaning | Floss threader or interdental brush needed | Brush and rinse the tray | Brush the plate and wire |
| Risk | Can debond or trap plaque | Can crack, warp or be lost | Can be lost or damaged |

Living with a permanent retainer
Floss with a floss threader, superfloss or a small interdental brush under the wire every day, because plaque and tartar build up easily around it. Regular professional cleaning helps, so keep up your check-ups. Avoid biting hard foods with the front teeth, ice and sticky sweets, and do not pick at the wire.
A permanent retainer can last for many years, but it can come loose or bend. If the wire detaches at one end, the teeth can move without you noticing, so see your dentist soon if it feels loose or sharp. Never try to fix it yourself. Discuss which type suits you with an orthodontist before braces come off, and see the guide on braces for adults if you are treating later in life, or metal braces for what comes before the retainer.
Common questions
How long does a permanent retainer last?
Many last for years, but there is no fixed lifespan. They can debond or wear, and your dentist checks the wire at each visit.
Can you eat normally with a permanent retainer?
Yes, but avoid very hard and sticky foods, and clean carefully after meals to prevent plaque build-up around the wire.
Is a clear retainer enough on its own?
Often yes, if worn as advised. Your orthodontist chooses based on how likely your teeth are to move.
What if my permanent retainer breaks?
Contact your dentist or orthodontist soon. A loose wire lets teeth shift, and a sharp end can cut the tongue.
