Retainers & Retention

Protecting the result you worked for — for life, not just until your last appointment.

The part of treatment that never really ends

When active orthodontic treatment finishes, your teeth aren't done moving. The bone and tissue surrounding them need time to stabilize in their new positions — and without a retainer, teeth will shift back toward where they started. This isn't a flaw in treatment; it's how teeth work.

Retention isn't an afterthought at Smile Suite. Dr. Kim plans for it from day one at our Evanston practice, because a beautiful result that doesn't last isn't actually a result worth having. The work you put in during treatment deserves to be protected for the long haul.

We'll set you up with the retention approach that fits your life, your anatomy, and your treatment outcome — and we'll be straightforward with you about what it takes to keep your smile where you want it.

Cleaning a retention appliance

Types of retainers

Clear Removable Retainer

A thin, clear tray that fits over your teeth — similar in appearance to an aligner but thicker and more durable. Worn nightly (and sometimes during the day in the early months after treatment), it holds your teeth in position while bone continues to stabilize.

Easy to clean Nearly invisible when worn Replaceable if lost or worn down

Bonded (Fixed) Retainer

A thin wire bonded to the tongue-facing surface of your front teeth — typically the lower four or six. It's permanently in place and requires no compliance. You don't have to think about it. It holds your front teeth in position continuously.

Always working — zero compliance required Invisible from the front Requires careful flossing around the wire

Combined Approach

Many patients use both: a bonded retainer for lower front teeth (where shifting is most common) alongside a removable clear retainer for the upper arch. We'll recommend the combination that gives your specific result the best long-term protection.

Maximum protection for high-risk areas Tailored to your anatomy and case Most common recommendation after comprehensive treatment

Retention over time

First 3–6 months

Full-time wear

Immediately after treatment, teeth are at the highest risk of shifting. We typically recommend wearing removable retainers full-time (22+ hours/day) during this initial stabilization period.

6 months – 1 year

Transition to nighttime wear

As stability improves, most patients transition to nightly wear. This is typically where patients settle long-term — and where most retainer neglect begins. We'll be direct about what happens if you stop.

Long term

Consistent nightly wear

Teeth move throughout life. Nightly retainer wear is the most reliable way to protect your result indefinitely. This isn't a short-term commitment — it's a lifetime one, and we'll help you make it as manageable as possible.

Lost your retainer? Teeth shifted?

We see patients regularly who finished treatment elsewhere — sometimes years ago — and now notice their teeth have shifted. In many cases, a new retainer can hold things where they are and prevent further movement. In some cases, a short course of treatment to correct the shift is a better option.

If you've lost your retainer, noticed movement, or simply need a replacement, we can help — whether or not you were ever a Smile Suite patient. Come in, let us take a look, and we'll tell you exactly where things stand.
