What is a fixed retainer?
A fixed retainer is a thin wire, usually attached with a special adhesive to the back of the lower and/or upper front teeth. It is not visible from outside and is not taken in and out. A fixed retainer is often used together with a removable retainer. For a comparison of the types, see the retainer guide.
Daily cleaning
- Brush your teeth at least twice a day, paying attention to the area right around the wire.
- To pass floss under the wire, you can use a floss threader or stiff-ended floss.
- An interdental brush helps to clean the area between the wire and the tooth.
- Regular dental check-ups and scaling reduce build-up around the wire.
Ask your orthodontist or hygienist which products suit you.
Why does tartar build up?
The wire creates a surface on the back of the teeth that is hard to clean, so tartar can build up more easily around a fixed retainer. If you notice red or bleeding gums, step up your cleaning and book a check-up.
If the wire breaks or comes loose
- Do not try to bend or re-bond the wire yourself.
- If it pokes your tongue or cheek, you can cover it temporarily with orthodontic wax.
- Contact the clinic promptly; teeth can shift while the wire is loose.
- If part of the wire has been swallowed or there is marked pain, call 112.
For similar situations, see our orthodontic emergencies page as well.
Hard foods
Biting hard and sticky foods with the front teeth can break the wire. It may be preferable to cut such foods into small pieces and chew them with the back teeth.
Check-ups
Whether the wire is intact is assessed at regular check-ups; you can add your check-up times to your calendar with the retainer check-up tracker.
For questions, you can call 0312 911 60 36 or use the form on the contact page.
If part of the appliance or wire has been swallowed, or if there is swelling in the mouth, marked pain or difficulty breathing or swallowing, call 112 without delay or go to the nearest emergency department.
This page is for general information only; your orthodontist decides the type of retainer, the wear schedule and how often you are seen for check-ups.
