Metal retainer top and bottom
Upper and lower metal retainers can hold tooth positions after orthodontic treatment when both arches need support.
The short answer
A removable or fixed metal retainer can be made for both the upper and lower arches when both need ongoing tooth-position support after orthodontic treatment.
How do upper and lower retainers hold teeth in place?
Upper and lower retainers hold teeth after braces or aligners by applying gentle contact through a wire and an acrylic or clear framework, or through a bonded wire fixed behind teeth. The design depends on tooth position, bite, hygiene, and relapse risk.
How should you wear and clean both retainers?
Wear removable retainers exactly as prescribed, clean them separately with cool water and a suitable brush, and store them in a ventilated case. For a bonded retainer, brush and use a threader or interdental brush around the wire.
When does a damaged retainer need prompt care?
Arrange prompt care if a retainer is bent, broken, loose, painful, or no longer fits. A loose bonded wire can let teeth move and can irritate the tongue or gums.
What should you ask about wearing two retainers?
Ask whether upper and lower retainers are both needed, which design suits your bite, and how long the prescribed wear schedule lasts. Ask how to clean around bonded wires and what to do if one breaks.
Frequently asked questions
Can home care replace a dental examination?
Home care can reduce irritation or improve cleaning, but it cannot diagnose or repair decay, infection, a crack, or gum-pocket disease.
What information should I bring?
Note when the problem began, its triggers, its location, changes over time, medicines used, and any recent dental treatment or injury.
