Would a retainer push your gaps in you teeth together?

A retainer can help maintain the position of your teeth after orthodontic treatment, but it typically won't actively push gaps together. If you have gaps that you want to close, you may need additional orthodontic treatment, such as braces or aligners. Some retainers, like bonded ones, can help stabilize teeth, but they don't exert significant force to close gaps on their own. It's best to consult with an orthodontist for personalized advice.
