Kinds of retainer
Dental retainers are removable or fixed appliances that hold teeth in their corrected positions after orthodontic treatment.
The short answer
Dental retainers come in removable clear or acrylic-and-wire designs and fixed bonded wires, each holding teeth after orthodontic movement.

How does a retainer keep teeth from moving back?
A retainer is an appliance that resists the small forces that can move teeth after braces or aligners. Removable retainers are usually clear thermoplastic shells or acrylic plates with a wire; fixed retainers are thin wires bonded to the tongue-side surfaces of selected teeth.
How should you follow your retainer wearing schedule?
Use the design and wearing schedule prescribed after checking your bite and the stability of each tooth. Clean a removable retainer with cool water and a soft brush, keep it in its case when it is out, and do not bend a fixed wire or use hot water on a plastic appliance.
When does a damaged retainer need a dental review?
Arrange a dental review if a retainer cracks, warps, feels sharp, no longer fits, or has detached from a tooth. Prompt care is also appropriate when teeth begin to rotate, a wire irritates the tongue, or the appliance causes a new bite contact.
Which retainer design would suit your bite best?
Ask which teeth need retention, whether a fixed, removable, or combined design suits your bite, and how often it should be worn. Ask how the retainer will be checked, cleaned, repaired, or replaced if its fit changes.
Frequently asked questions
Can I choose a retainer myself?
The choice depends on tooth position, bite, hygiene, dexterity, and the risk of unwanted movement, so it is made after an orthodontic assessment.
Can a retainer straighten teeth again?
It can hold or make very minor settling movements, but a poorly fitting retainer should not be used to force a tooth into position.
