Orthodontics · Retention

Keep your straightened smile lasting forever.

Retention is the protective phase following braces or clear aligner treatment that prevents teeth from shifting back to their original positions. Using a fixed wire bonded behind the teeth or transparent retainer trays worn at night, the results of your orthodontic treatment are secured for the long term. The permanence of the straight smile you worked months to achieve depends entirely on how well this phase is managed.

What is retention

What is retention (retainer) treatment?

When orthodontic treatment ends, the teeth have been moved to their new positions; however, the surrounding bone and periodontal fibers have not yet fully adapted to this new alignment. These tissues carry a memory of the original position and tend to pull the teeth back. Retention is the protective phase in which appliances called retainers hold the teeth in their new positions, giving the surrounding tissues time to remodel and adapt.

Retention is not a separate "additional treatment" — it is the natural final stage of orthodontic care. Regardless of whether braces or clear aligners were used, retention is required after any treatment that moves teeth; skipping it means the results will not last.

Why do teeth want to drift back?

The periodontal fibers that anchor teeth to the bone are elastic and retain a memory of the original tooth position. Once treatment ends, these fibers pull the teeth back toward where they were — a process called relapse.

Does a retainer move teeth?

No. Brackets and clear aligners are designed to move teeth, while a retainer is designed to hold them in place. This is why the retention phase is pain-free and does not interfere with daily life.

My treatment is done — is retention really necessary?

Yes. Partial or complete return to the original tooth alignment when retention is skipped is the most common orthodontic complication; months of treatment results can be lost in a short time.

Why it matters

Why is retention so important?

Success in orthodontics is not only about straightening teeth — it is about maintaining that straight alignment for life. Retention is the guarantee of that permanence.

Preserves treatment results

Prevents teeth from shifting back to their original positions, making the straight alignment achieved with braces or clear aligners permanent.

Gives tissues time to adapt

Bone and periodontal fibers need time to remodel around the teeth's new positions; the retainer keeps teeth stable throughout that process.

Prevents retreatment

Repeating orthodontic treatment due to relapse is both time-consuming and costly; consistent retainer wear eliminates this risk.

Comfortable and discreet

A fixed retainer is hidden behind the teeth, while removable trays are typically worn only at night — no visible change in daily appearance.

Who it is for

Who needs retention treatment?

Retention is indicated for every patient whose teeth have been moved orthodontically. The type of retainer recommended depends on the treatment used, the severity of the original crowding, and your lifestyle — determined by your dentist at the end of treatment.

Patients who have just finished braces

Retention begins on the same day the brackets are removed; in most cases a fixed retainer is bonded behind the front teeth, supplemented if needed with a night-time tray.

Patients who have completed clear aligner treatment

The risk of relapse is identical after clear aligner (Invisalign-type) treatment; protection is maintained with retainer trays or a fixed retainer following the final aligner.

Patients who stopped wearing their retainer

Cases where retention was discontinued early and tooth movement has been noticed are re-evaluated; when caught early, a new retainer or a short course of aligner treatment usually recovers the alignment.

Is there a difference between children and adults?

Retention is necessary at every age. For children still in the growth phase, check-up intervals are kept more frequent because the jaw continues to develop; in adults, tissue adaptation is slower, so the retention period is generally longer.

Methods

Types of retainers

Fixed and removable options can be used individually or in combination; the right protocol is planned by your dentist at the end of your treatment.

Fixed (Lingual) RetainerBonded behind the teeth

A thin twisted wire bonded to the back surface of the front teeth. Invisible from the outside, requires no removal, and carries no risk of being forgotten — providing the most reliable long-term protection.

Essix (Clear Tray) RetainerRemovable · invisible

A thin transparent tray custom-made from impressions of your teeth. Typically worn all day during the initial period, then only at night; removed for eating and brushing.

Hawley RetainerRemovable · adjustable

The classic appliance with an acrylic palatal plate and a thin metal arch. Durable and adjustable by the dentist in small increments; particularly suitable for children and younger patients.

Combined ProtocolFixed + removable

The safest approach in most cases: a fixed retainer is bonded behind the teeth and supplemented with a clear night-time tray. Dual protection minimizes relapse risk.

Process

How does the retention process work?

A comfortable protection phase that begins on the day your brackets are removed or your final aligner is finished, maintained through regular check-ups.

End-of-treatment assessment

When your orthodontic treatment is complete, the final tooth alignment, your bite, and your gum health are evaluated; the most suitable retainer protocol for you is determined.

Retainer placement

A fixed retainer is bonded behind the teeth in the same appointment; for a removable tray, a precise impression is taken and delivered promptly.

Wear schedule

You receive a clear schedule covering when and how long to wear the tray, how to clean it, and how to store it; the rules for the initial period are especially important.

Regular check-ups

At scheduled intervals, the condition of the retainer and the position of your teeth are monitored; wear time is gradually reduced as the surrounding tissues adapt.

Use and care

What should you keep in mind while wearing a retainer?

The success of retention largely rests in your hands; a few simple habits protect your results for life.

Stick to your wear schedule

Removable trays must be worn for as long as your dentist prescribes; skipping nights, especially in the first few months, can cause teeth to start shifting.

Do not neglect cleaning

Trays should be cleaned at least once a day with a soft brush and mild soapy lukewarm water; the area around a fixed retainer should be flossed and cleaned with an interdental brush. Hot water warps the tray.

Do not wait when it breaks or comes loose

If one end of a fixed retainer comes unglued or a tray cracks, teeth can shift quickly; contact your clinic as soon as possible.

Store it in its case

A removed tray should never be wrapped in a napkin — always keep it in its case; most tray losses happen when the appliance is wrapped in a napkin during meals.

Frequently asked questions

Common questions about retention

How long do I need to wear my retainer?
Duration varies from person to person. The first year is the most critical and requires strict compliance; after that, wear typically reduces to nights only. Fixed retainers can remain in the mouth for years without any issues. Many orthodontists recommend making the night-time tray a lifelong habit to protect results permanently.
What happens if I stop wearing my retainer?
Teeth — especially in the first months after treatment — begin drifting back toward their original positions. This shift usually appears first as mild crowding in the lower front teeth and gradually worsens. In cases of significant relapse, partial or complete repetition of orthodontic treatment may be necessary.
Which is better — a fixed retainer or a removable tray?
Both serve the same purpose but have different strengths. A fixed retainer cannot be forgotten and is invisible; a removable tray is easy to clean and covers all the teeth. In most cases, the combined protocol using both together gives the safest outcome; the decision is made together with your dentist based on the specifics of your treatment.
Does a retainer affect speaking or eating?
A fixed retainer sits behind the teeth, so it does not affect speech or eating at all; most patients adapt within a few days. Removable trays may cause a slight change in speech during the first few days, which passes quickly; they are removed for meals anyway.
My fixed retainer broke — what should I do?
If one end of the wire has come unglued or separated from a tooth, contact your clinic without delay; teeth can shift in a short time. In most cases the wire is re-bonded in the same appointment. If you have a night-time tray available, continue wearing it until your appointment to maintain protection.
How much does retention treatment cost?
The fee varies by case and depends on the type of retainer chosen (fixed, removable, or combined) and the number of arches treated. Retention is often considered part of the overall orthodontic treatment plan. Please book a consultation for a personalized quote.
