What This Guide Covers and Who It Is For
This guide explains the three main retainer types used after orthodontic treatment and helps you understand which one may work best for you.
After braces are removed or aligner treatment ends, teeth have a natural tendency to drift back toward their original positions. This process is called orthodontic relapse. A retainer is a custom dental appliance designed to hold your teeth in their corrected alignment while the bone and soft tissues around them stabilize. [1]
Whether you just finished treatment, are planning to start, or need a replacement retainer, this guide covers the design, pros, cons, costs, and daily care for each type. It is written for adult and adolescent patients, as well as parents choosing retainers for their children. For broader information about orthodontic treatment options, visit the orthodontics page.
Your orthodontist will recommend a retainer type based on your bite, the complexity of your case, and your lifestyle. Understanding the options ahead of time helps you ask better questions and feel confident in the decision.
The Three Main Retainer Types Compared
Hawley, clear, and permanent retainers each hold teeth in place using different designs, materials, and wearing schedules.
No single retainer type is universally better than the others. Each has strengths and trade-offs. The sections below break down how each one works, what it feels like, and who it tends to suit best. [1]
Hawley Retainers: Wire and Acrylic
A Hawley retainer is the traditional removable retainer made from a molded acrylic base and a metal wire. The acrylic plate sits against the roof of your mouth (or behind your lower teeth). The wire curves around the front of your teeth to hold them in position.
Hawley retainers are durable and adjustable. If minor tooth movement occurs, your orthodontist can bend the wire to guide teeth back into alignment. The acrylic base can also be customized with colors or patterns, which some younger patients enjoy.
The main drawback is visibility. The metal wire shows when you smile or talk. Some patients also find the acrylic plate bulky at first, and it can affect speech slightly during the first few days of wear. With consistent use, most people adjust within a week.
Hawley retainers typically last 3 to 5 years or longer with proper care. They are easy to clean and can be repaired if the wire bends or the acrylic cracks.
- Material: Acrylic base with stainless steel wire
- Visibility: Wire is visible across front teeth
- Adjustability: Orthodontist can adjust wire for minor corrections
- Durability: Typically lasts 3 to 5 years or more
- Cleaning: Brush gently with a soft toothbrush; soak in retainer cleaner as directed
Clear Retainers: Essix-Style Vacuum-Formed
Clear retainers, often called Essix retainers, are made from thin, transparent plastic that fits snugly over your teeth. They look similar to clear aligner trays. Because the plastic is nearly invisible, many patients prefer them for cosmetic reasons.
These retainers are lightweight and comfortable for most people. They do not affect speech as much as Hawley retainers. However, they cannot be adjusted. If significant shifting occurs, a new retainer must be made rather than modifying the existing one.
Clear retainers are more prone to wear and discoloration over time. They can crack, warp from heat, or become cloudy. Drinking hot beverages or leaving them in a hot car can damage the plastic. Most clear retainers last 1 to 3 years before needing replacement, though some patients report shorter lifespans depending on grinding habits.
Because clear retainers cover the biting surfaces of your teeth, they also double as a light protective layer for patients who clench or grind at night. However, they are not a substitute for a dedicated night guard if you have significant bruxism (teeth grinding).
- Material: Thin, transparent thermoplastic
- Visibility: Nearly invisible when worn
- Adjustability: Cannot be adjusted; must be replaced if fit changes
- Durability: Typically lasts 1 to 3 years
- Cleaning: Rinse with cool water; brush gently; avoid hot water
Permanent Retainers: Bonded Wire Behind the Teeth
A permanent retainer, also called a bonded or fixed retainer, is a thin wire glued to the back surface of your front teeth. It stays in your mouth 24 hours a day, 7 days a week. You cannot remove it yourself. [1]
Permanent retainers are most commonly placed on the lower front teeth, where relapse is especially common. They can also be placed on upper front teeth in certain cases. Because the wire sits behind the teeth, it is invisible when you smile.
The biggest advantage is compliance. You do not have to remember to put it in or take it out. The retainer works continuously. This makes it a strong option for patients who may struggle with wearing a removable retainer consistently.
The downside is oral hygiene. Flossing around a bonded wire requires a floss threader or a specialized tool like a water flosser. Food can get trapped along the wire. If the bond breaks or the wire detaches from a tooth, that tooth may begin to shift before you notice the problem. Regular dental checkups are essential so your dentist or orthodontist can check the bond integrity. [2]
- Material: Thin stainless steel or braided wire bonded with dental composite
- Visibility: Invisible (placed on the tongue side of teeth)
- Adjustability: Cannot be adjusted; must be rebonded or replaced if damaged
- Durability: Can last 5 to 20 years or longer with proper monitoring
- Cleaning: Floss threaders, interdental brushes, or water flossers required daily
Practical Details: Wear Time, Age, and Daily Care
How long and how often you wear your retainer directly affects whether your teeth stay aligned.
Recommended Wearing Schedule
Most orthodontists recommend wearing removable retainers full-time (20 to 22 hours per day) for the first 3 to 6 months after braces are removed. After that initial period, the schedule typically shifts to nighttime-only wear. [1]
Nighttime retainer wear is generally recommended for the long term, and in many cases, indefinitely. Teeth can shift at any age due to normal changes in the jawbone and surrounding tissues. Stopping retainer use, even years after treatment, increases the risk of relapse. [2]
Permanent retainers do not follow a wearing schedule because they are always in place. However, some orthodontists recommend wearing a removable retainer in addition to a permanent one, especially on the upper arch where a bonded wire is less commonly placed.
Age and Timing Considerations
Retainers are prescribed for patients of all ages after orthodontic treatment. For children and teens, removable retainers require a level of responsibility. Parents should supervise younger patients to build consistent habits.
Adults may prefer clear or permanent retainers for aesthetic reasons. Adults also tend to experience slower bone remodeling, which can mean that retention is especially important for maintaining results over decades.
If you had orthodontic treatment as a teen and stopped wearing your retainer years ago, minor shifting is common. An orthodontist can evaluate whether your current alignment needs correction or whether a new retainer alone can maintain the remaining alignment.
Cleaning and Caring for Your Retainer
Proper care extends the life of any retainer and protects your oral health. For Hawley and clear retainers, rinse them with cool water each time you remove them. Brush them gently with a soft-bristled toothbrush. Avoid using toothpaste on clear retainers, as abrasive ingredients can scratch the plastic and make it cloudy.
Soak removable retainers in a denture cleaner or retainer cleaning solution once daily or as your orthodontist recommends. Never place clear retainers in hot water or leave them in direct sunlight, as heat warps the plastic.
For permanent retainers, spend extra time on oral hygiene each day. Use a floss threader, an interdental brush, or a water flosser to clean around and beneath the wire. Plaque and tartar build up quickly along a bonded wire if you skip this step. [2] Your dental hygienist can also clean around the wire during routine visits.
What Happens When You Get a Retainer
Getting a retainer is a quick, painless process that typically happens on the same day your braces are removed or shortly after.
Getting Fitted for a Removable Retainer
For a Hawley or clear retainer, your orthodontist takes an impression or digital scan of your teeth. This creates a precise model of your new tooth positions. The retainer is then fabricated in a dental lab or, in some offices, made on-site using a 3D printer or vacuum-forming machine.
Turnaround time varies. Some practices deliver the retainer the same day. Others may take a few days to a week. Your orthodontist will check the fit, make any small adjustments, and explain your wearing schedule. The appointment typically lasts 15 to 30 minutes.
Expect mild pressure and a slightly strange sensation when you first wear the retainer. Some lisping is normal for the first 1 to 3 days, especially with a Hawley retainer. Reading aloud or talking more than usual can help your tongue adapt quickly.
Placing a Permanent Retainer
Bonding a permanent retainer takes about 15 to 30 minutes. Your orthodontist cleans and dries the back surfaces of the teeth where the wire will attach. A dental adhesive (composite resin) is applied to bond the wire to each tooth, then hardened with a curing light.
The process is painless and does not require numbing. You may feel the wire with your tongue for the first few days. Most patients get used to it within a week.
Your orthodontist will check the retainer at follow-up visits to make sure the bonds are intact. If you feel a loose spot or notice a tooth shifting, contact your orthodontist promptly. Early rebonding can prevent further movement.
Retainer Costs and Insurance Coverage
Retainer costs depend on the type, your location, and your provider. Costs vary by location, provider, and case complexity.
Removable retainers, both Hawley and clear, typically cost between $100 and $500 per retainer. You may need one for the upper arch, one for the lower arch, or both. Permanent retainers generally cost between $150 and $500 per arch for placement.
Many orthodontic treatment plans include the initial set of retainers in the overall fee. Ask your orthodontist whether retainers are included before treatment begins. Replacement retainers are usually an additional cost. Clear retainers may need replacing every 1 to 3 years, while Hawley retainers can last longer.
Dental insurance plans that cover orthodontic treatment sometimes include retainers under the same benefit. However, replacement retainers may not be covered. Check with your insurance provider for specific details about your plan. Flexible spending accounts (FSAs) and health savings accounts (HSAs) can typically be used for retainer costs as well.
When to See an Orthodontist About Your Retainer
See an orthodontist if your retainer no longer fits, if your permanent retainer wire breaks, or if you notice teeth shifting.
A general dentist can check a permanent retainer during routine exams and may rebond a loose wire in some cases. However, an orthodontist has the specialized training to evaluate whether shifting has occurred, whether the retainer design still meets your needs, and whether any corrective steps are necessary. [1]
You should also see an orthodontist if you lost your retainer and more than a few days have passed. Teeth can begin to shift quickly, especially in the first year after braces. Getting a replacement retainer as soon as possible reduces the risk that the new retainer will not fit because teeth have already moved.
If it has been years since you wore a retainer and you notice crowding or spacing returning, an orthodontist can assess the degree of relapse and discuss options. In mild cases, a new retainer may stabilize the teeth in their current position. In more significant cases, a short course of retreatment with aligners or braces may be recommended before new retainers are made.
