Why Retainers Matter

Finishing Treatment Is Not the End of It

Teeth are held in place by bone and soft tissue that need time to settle around their new positions. Without retention, teeth tend to drift back toward where they were, which is known as orthodontic relapse.

This is normal biology rather than a sign that treatment failed, and it is the reason retention is planned as part of treatment rather than as an afterthought.

The Options

Removable and Fixed Retainers

Removable Retainers

Taken in and out, usually a clear tray or a wire-and-acrylic design. Easy to clean, but they only work while they are actually in.

Fixed Retainers

A thin wire bonded behind the front teeth, holding them in position without anything to remember. It stays put until Dr. Kim removes it.

Looking After It

Keeping a Retainer Working

Keep It Clean

Rinse and clean a removable retainer as Dr. Kim instructs. Hot water can distort some retainers, so avoid it.

Use the Case

Retainers left wrapped in a napkin get thrown out. The case exists for a reason.

Brush Around a Fixed Wire

A bonded wire needs careful flossing around it. We will show you how at your visit.

Bring It to Checkups

Bring your retainer along so Dr. Kim can check the fit and that nothing has shifted.

When Something Goes Wrong

Lost, Broken or Tight Retainers

Lost Retainer

Call us. Teeth can start to move within a short time without retention, so a replacement is usually made sooner rather than later.

Contact Us →

Broken or Cracked Retainer

Stop wearing a cracked retainer, as it may not fit correctly and can irritate the gums. Call us for a replacement.

Fixed Retainer Came Loose

A detached or broken bonded wire should be looked at promptly, since the teeth behind it are no longer being held.

It Feels Tight Again

Often a sign the teeth have started to shift. Do not force a retainer that no longer seats properly. Call us instead.

Shifting After Treatment

If Your Teeth Have Already Moved

Teeth that shifted after braces years ago are common, and the correction needed is sometimes smaller than the original course of treatment. Dr. Kim will look at how much has changed and talk through whether retention alone is enough or whether a short course of Braces or Clear Aligners makes more sense first.

See Adult Orthodontics for more on treating relapse.

Common Questions

Retainers FAQ

Teeth have a tendency to move after treatment. A retainer holds the corrected position while the surrounding bone and gum tissue settle, and helps maintain the result afterwards.

Retention is usually long term, and how much wear is needed changes over time. Dr. Kim gives you a specific schedule for your case and adjusts it at follow-up visits.

Come in and we will look. If the teeth have shifted, Dr. Kim will tell you whether a new retainer is enough or whether correction is needed first.

Yes. Dr. Kim can evaluate how your teeth sit now and make a new retainer, as long as the fit and bite are appropriate.

Neither suits everyone. It depends on the case, the teeth being held and how realistic consistent wear is. Dr. Kim will recommend what fits your situation.

Sometimes, if the shift is small. Larger relapse may need a short course of treatment first, then retention to hold it.

Call us soon, since teeth can begin to shift without it. A lost or broken retainer is usually not an emergency, but it should be replaced promptly. See Orthodontic Emergencies.
