What D8680 means

D8680 covers orthodontic retention, including the removal of appliances and the construction and placement of retainer(s). "D" is dental, "86" is the orthodontic adjunctive group, and "80" is this retention. After active orthodontic treatment moves the teeth into their corrected positions, the braces (or the final aligners) are removed, and the patient enters the retention phase. Retainers — custom appliances that hold the teeth in their new positions — are made and provided, and the patient wears them to prevent the teeth from shifting back.

Retention is a crucial part of orthodontic treatment, not an optional add-on. Teeth have a natural tendency to drift back toward their original positions (relapse), especially in the period right after treatment, because the surrounding bone and gum tissues need time to stabilize around the new positions, and natural forces continue to act on the teeth. Retainers counteract this.

D8680 covers the retention phase including appliance removal and the retainers. In comprehensive treatment, retention is often considered part of the overall case fee (so separate billing may be denied or included). There are different retainer types (removable like Hawley or clear retainers, or fixed/bonded retainers). Replacement retainers have their own codes (D8703 maxillary, D8704 mandibular). Retention is typically needed long-term.

When it's typically used

D8680 is reported for the retention phase after active orthodontic treatment — removing the braces or appliances and providing retainers to hold the teeth in their corrected positions, preventing them from drifting back (relapse).

How much does D8680 cost?

Orthodontic retention is often included in the overall comprehensive treatment fee rather than charged separately — the case fee (D8080/D8090) frequently covers the retention phase and initial retainers. When itemized, retainers themselves are a modest cost; replacement retainers (if lost or broken) are typically an additional out-of-pocket cost.

Is D8680 covered by insurance?

Retention is usually considered part of the global orthodontic fee, so separate billing of D8680 may be denied or bundled into the comprehensive treatment benefit. Replacement retainers (D8703/D8704) are typically not covered and are out of pocket. Understanding that retention is part of the overall treatment helps clarify the coverage.

Why retainers are essential after braces

Many people are surprised to learn that orthodontic treatment doesn't end when the braces come off — the retention phase is critical, and understanding why explains the importance of retainers.

When teeth are moved into new positions by orthodontic treatment, the surrounding bone and gum tissues that hold them have been remodeled, but right after treatment these supporting structures are not yet fully stabilized around the new positions — they need time (months) to firm up. During this period, and to some extent indefinitely, teeth have a natural tendency to drift back toward where they were (called relapse), driven by the unstable tissues, the memory of the periodontal fibers, and ongoing natural forces like chewing, the tongue, and lips. Without something holding them, the teeth can shift, undoing the results of the treatment.

Retainers prevent this. By holding the teeth in their corrected positions, retainers give the bone and gums time to stabilize and counteract the forces that would cause relapse. This is why retention isn't optional — skipping retainers, or not wearing them as directed, is one of the most common reasons people see their teeth shift back after braces (sometimes significantly, requiring re-treatment). The investment of time and money in straightening the teeth is protected by faithfully wearing retainers. Understanding that retention is an integral, essential part of orthodontic treatment — not an afterthought — helps patients commit to it and preserve their results.

Types of retainers

Retainers come in several types, and understanding the options helps clarify what to expect during the retention phase.

Removable retainers are the most familiar. A Hawley retainer is the classic type — a custom acrylic piece that fits against the roof of the mouth (or along the lower teeth) with a wire that goes across the front teeth; it's durable and adjustable. Clear retainers (like Essix or Vivera) are transparent trays that fit over the teeth, similar to clear aligners — they're nearly invisible and popular, though they can wear out over time. Removable retainers are taken in and out by the patient, typically worn full-time at first and then often just at night long-term. Fixed (bonded) retainers are thin wires bonded to the back of the front teeth, permanently holding them in place without the patient needing to remember to wear anything — common for the lower front teeth, though they require careful cleaning and can occasionally come loose.

The choice depends on the case, the teeth involved, the patient's preferences and discipline, and the orthodontist's recommendation. Some patients have a combination (for example, a fixed retainer on the lower front teeth and a removable one for the upper). Each type effectively holds the teeth when used as directed. The orthodontist provides the retainer(s) as part of the retention phase and instructs the patient on the wear schedule and care, which are key to keeping the teeth in their corrected positions long-term.

How long do you have to wear retainers?

A very common question after braces is how long retainers must be worn, and the honest answer is longer than many people expect — often indefinitely.

Typically, retainers are worn full-time (or close to it) for a period right after the braces come off — often several months — when the teeth are most prone to relapse and the supporting tissues are stabilizing. After that, the orthodontist usually transitions the patient to wearing removable retainers part-time, most commonly just at night while sleeping. The reality that surprises many people is that this nighttime retainer wear is often recommended indefinitely — essentially for life — because teeth can continue to shift slowly throughout life (teeth naturally have some tendency to move with age, even in people who never had braces). Wearing a retainer at night long-term is the insurance against this gradual shifting.

The specific schedule depends on the case and the orthodontist's guidance, but the key message is that retention is a long-term, often lifelong commitment if you want to keep your teeth straight. Fixed (bonded) retainers handle this automatically by staying in place permanently (until removed). For those with removable retainers, the small effort of wearing them at night is what preserves the results of treatment over the years. Understanding upfront that 'retainers are forever' (at least at night) helps patients commit to the habit and avoid the disappointment of seeing their teeth gradually shift back after investing in orthodontic treatment.

Caring for and replacing retainers

Retainers need proper care to remain effective, and knowing how to care for them — and what to do if one is lost or broken — helps protect your orthodontic results.

For removable retainers, care includes cleaning them regularly (gently brushing them, and soaking or cleaning as the orthodontist recommends — avoiding hot water, which can warp them), storing them in their case when not worn (a leading cause of lost or damaged retainers is wrapping them in a napkin and accidentally throwing them away, or leaving them where a pet can chew them), and keeping them away from heat. For fixed retainers, careful cleaning around the bonded wire — using floss threaders or a water flosser to clean under it — is important to prevent plaque buildup and decay, and the patient should report if the wire comes loose. Bringing retainers to dental and orthodontic check-ups lets them be inspected.

If a retainer is lost or broken, it's important to get it replaced promptly — even a short period without retention can allow the teeth to start shifting, and a replacement that no longer fits because the teeth moved is a sign of why. Replacement retainers have their own codes (D8703 for upper, D8704 for lower) and are typically an out-of-pocket cost, usually not covered by insurance. To avoid the cost and risk, taking good care of the retainers and not going without them is worthwhile. Because retention is often lifelong, retainers may eventually wear out and need replacing over the years, which is a normal part of maintaining orthodontic results long-term.

Frequently asked questions

What is the D8680 dental code?

It's orthodontic retention — the phase after active treatment, including removing the braces or appliances and providing retainers to hold the teeth in their new positions and prevent them from drifting back.

Why do I need a retainer after braces?

Teeth naturally tend to drift back (relapse) after treatment, because the supporting bone and gums need time to stabilize and natural forces continue. Retainers hold the teeth in place to prevent this.

What types of retainers are there?

Removable ones (Hawley with a wire, or clear trays like Essix) that you take in and out, and fixed (bonded) retainers — thin wires bonded behind the front teeth that stay in permanently.

How long do I have to wear a retainer?

Usually full-time at first, then often just at night — frequently indefinitely (for life), since teeth can keep shifting slowly with age. Nighttime wear long-term protects your results.

Is retention included in the cost of braces?

Often yes — retention is usually considered part of the overall comprehensive treatment fee, including the initial retainers. Replacement retainers if lost or broken are typically extra.

What if I lose my retainer?

Get it replaced promptly, since teeth can shift quickly without retention. Replacement retainers (D8703 upper, D8704 lower) are typically out of pocket and not covered by insurance.
