If you have just finished braces or Invisalign, you have probably heard the word “retainer” about a thousand times. But when the bill arrives, or when you call your insurance company, things get confusing very fast.
You might see a strange string of numbers on your treatment plan. That is the dental code. And honestly, understanding that code can save you a lot of money and headaches.
Many patients ask the same question: What is the exact dental code for upper and lower retainers?
The short answer is that there isn’t just one single code. The code changes depending on whether you are getting a fixed retainer, a removable Hawley retainer, or a clear Essix retainer. It also changes if you are replacing an old retainer versus getting your very first one after braces.
In this guide, we will walk through every dental code you need to know. We will keep things simple, clear, and practical. No confusing medical jargon. Just honest, realistic advice to help you understand your bill and talk to your dentist like a pro.
Let us start with the basics.
Understanding How Dental Codes Work for Retainers
Before we dive into the specific numbers, it helps to understand what these codes actually are. Dentists and insurance companies use a standardized system called CDT codes (Current Dental Terminology). Think of it like a price tag menu for every single thing a dentist can do.
Every procedure has a unique five-character code. For retainers, the codes live in the “prosthodontic” section. This sounds fancy, but it simply means anything that replaces or holds teeth in place.
The tricky part is that insurance companies treat retainers very differently from other dental work. Many plans consider retainers “orthodontic” rather than general dental care. And orthodontic benefits usually have their own rules, waiting periods, and maximum coverage limits.
So when you search for the dental code for upper and lower retainers, remember that the code is just the first step. Your insurance plan’s specific orthodontic policy is what really decides how much you pay out of pocket.
Why Two Retainers (Upper and Lower) Have Different Billing Rules
You might assume that billing for an upper retainer and a lower retainer uses the exact same code twice. That is partially true. Most dentists will bill the same procedure code for each arch. But there is a catch.
Some codes are designed to cover both arches in one fee. Other codes charge per arch. This distinction matters a lot for your wallet.
For example, a removable retainer code like D8680 is often billed per arch. That means you will see a charge for D8680 on the upper and another D8680 on the lower. Two separate line items.
But a fixed retainer code like D8690 might be billed once for the entire case if both upper and lower are done at the same appointment.
Understanding this small difference can prevent a very awkward phone call when you get your bill and think you were charged twice by mistake.
The Primary Dental Codes for Upper and Lower Retainers
Let us get straight to the numbers you came here for. These are the legitimate, current CDT codes used by dentists across the United States as of 2026.
| CDT Code | Procedure Name | What It Covers | Typical Arch Billing |
|---|---|---|---|
| D8680 | Removable Retainer Appliance | Hawley or clear Essix retainers | Per arch (upper + lower = two units) |
| D8690 | Orthodontic Retainer Adjustment/Repair | Fixing broken or loose retainers | Per visit or per retainer |
| D8695 | Removal of Fixed Retainer | Taking out a bonded permanent retainer | Per arch |
| D8697 | Replacement of Retainer (Full) | Making a brand new retainer | Per retainer |
These four codes cover almost every retainer situation you will encounter. But the two you need to know best are D8680 and D8697.
Code D8680: The Removable Retainer Standard
Code D8680 is the workhorse of the retainer world. When most people say “dental code for upper and lower retainers,” they are actually thinking of D8680.
This code covers the fabrication and placement of a removable retainer. That includes:
- Taking impressions or digital scans of your teeth
- Sending the molds to a dental lab
- Creating the retainer itself
- Fitting the retainer in your mouth
- Adjusting it for comfort
Whether you choose a classic Hawley retainer (the one with the metal wire and pink plastic) or a clear Essix retainer (like a thin, hard version of Invisalign), the code is usually D8680.
One very important note: D8680 is almost always billed per arch. So for upper and lower retainers, you will see two separate charges. The total cost is simply the price of one D8680 multiplied by two.
Code D8697: When You Need a Replacement Retainer
Life happens. Retainers get lost. Dogs chew them. They accidentally go into the trash at a restaurant. If that sounds familiar, your dentist will use code D8697.
This code specifically means “replacement of a retainer.” It assumes you already had a retainer before, and now you need a new one because the old one is gone, broken beyond repair, or does not fit anymore.
Insurance companies pay close attention to this distinction. Many plans cover replacement retainers at a lower percentage than the original retainer. Some only cover one retainer per arch every five or ten years.
For upper and lower replacements, you will likely see D8697 billed twice—once for the upper, once for the lower.
Fixed Retainers vs. Removable Retainers: Different Codes, Different Rules
Not all retainers come in and out of your mouth. Some are glued permanently to the back of your teeth. These are called fixed or bonded retainers. They are most common on the lower front teeth, but some patients have them on the upper front teeth too.
The coding for fixed retainers is completely different.
Code D8695: Removal of a Fixed Retainer
One day, you might decide you have had enough of that permanent wire. Or your dentist might recommend removing it because it is collecting too much plaque. That removal procedure uses code D8695.
This is important because removal is not included in the original retainer fee. If you had a fixed retainer placed years ago, that placement was likely billed under a different code (often bundled into your original orthodontic treatment). But the removal is a separate charge.
For upper and lower fixed retainer removal, the dentist will bill D8695 for each arch.
What About Placing a New Fixed Retainer?
Interestingly, there is no single, universal CDT code just for “placing a fixed retainer.” Why? Because most fixed retainers are placed at the very end of active orthodontic treatment. The placement is usually considered part of the comprehensive orthodontic case.
If you have a fixed retainer placed outside of a full orthodontic case (for example, years later as a standalone procedure), the dentist may use a combination of D8690 and D8680, or they may use a miscellaneous code like D8999 (unspecified orthodontic procedure). This is rare, but it happens.
Realistic Costs: How Much Will Upper and Lower Retainers Actually Cost?
Let us talk money. This is what most people really want to know. The dental code tells you what the procedure is, but the price tag varies wildly.
Here are realistic, average costs for upper and lower retainers in the United States without insurance.
| Type of Retainer | Average Cost for Upper Only | Average Cost for Lower Only | Total for Upper + Lower |
|---|---|---|---|
| Hawley (wire and acrylic) | $300 – $500 | $300 – $500 | $600 – $1,000 |
| Clear Essix (vacuum-formed) | $200 – $400 | $200 – $400 | $400 – $800 |
| Fixed (bonded wire) | $250 – $600 | $250 – $600 | $500 – $1,200 |
These prices include the dentist’s exam, the lab fees, and the fitting appointment. If you need a replacement retainer (code D8697), expect costs on the higher end of these ranges.
Why Is There Such a Big Price Range?
Several factors explain the wide range:
- Geographic location. A dentist in Manhattan, New York, will charge more than a dentist in rural Alabama. Rent and staff salaries drive prices up.
- Digital vs. traditional impressions. Digital scanners cost a lot of money. Some dentists pass that cost to you. Traditional putty impressions are cheaper but less comfortable.
- In-house lab vs. external lab. Some dental offices have their own 3D printers and make retainers on-site. Others send molds to an external lab. In-house labs are usually faster and slightly cheaper.
- Type of material. Thicker clear plastic retainers last longer and cost more. Thinner ones break faster but are cheaper upfront.
How Insurance Handles the Dental Code for Upper and Lower Retainers
This is where things get frustrating for many patients. You might assume that your dental insurance covers retainers because retainers are medically necessary to prevent your teeth from shifting back. Unfortunately, insurance companies do not always see it that way.
The “Orthodontic Benefit” Problem
Most standard dental PPO plans include separate “orthodontic benefits.” These benefits usually have:
- A lifetime maximum (often $1,000 to $3,000)
- A requirement that you are under 19 years old
- A rule that retainers are only covered right after braces
If you finished braces five years ago and now need a replacement retainer, your orthodontic benefit is likely long gone. Many plans close the orthodontic benefit once you complete active treatment.
In that case, your retainer falls under “general dental” coverage. But here is the catch: many general dental plans explicitly exclude retainers because they consider them orthodontic appliances.
How to Check Your Coverage Before You Get a Retainer
Do not assume anything. Call your insurance company or log into your patient portal. Ask these three specific questions:
- “Does my plan cover code D8680 for removable retainers?”
- “Is there a separate orthodontic lifetime maximum, and has it been used up?”
- “Are upper and lower retainers considered two separate procedures or one procedure for coverage purposes?”
Write down the answers. Get the representative’s name. Keep a record. This small step can save you from a surprise $800 bill.
Medicare and Medicaid: What You Need to Know
Original Medicare (Part A and Part B) does not cover routine dental care, including retainers. Some Medicare Advantage plans (Part C) include dental benefits, but they rarely cover retainers unless you had recent jaw surgery or trauma.
Medicaid coverage varies by state. Some state Medicaid programs cover retainers for children under 21 as part of the Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit. Adult Medicaid coverage for retainers is extremely rare.
The Patient’s Guide to Saving Money on Upper and Lower Retainers
You do not have to pay full price just because your insurance says no. Here are realistic, legal ways to save money.
Option 1: Ask for the Cash Discount
Many dental offices offer a 10% to 20% discount if you pay with cash or a credit card at the time of service. Why? Because the office does not have to spend staff time filing insurance claims, waiting for reimbursement, or chasing down denied claims.
Simply ask: “If I pay in full today without using insurance, can you offer a cash discount?” The worst they can say is no. Most will say yes.
Option 2: Use a Dental School
Dental schools need patients for their students to practice on. Everything is supervised by licensed, experienced dentists. The appointments take longer, but the prices are significantly lower.
For upper and lower retainers, a dental school might charge $200 to $400 total—not per arch. That is a huge saving. Search for “dental school near me” or check the American Dental Education Association’s directory.
Option 3: Online Retainer Companies
Several companies now offer direct-to-consumer retainers. You take an impression kit at home, mail it in, and they ship you retainers. Examples include SportingSmiles, Remi, and SDC (SmileDirectClub retainers, though the company itself faced legal issues, their retainer business still operates under new ownership).
These options are much cheaper, often $100 to $200 for both upper and lower retainers. However, there is a risk. No dentist checks the fit. No one adjusts them for pressure points. If the retainers do not fit correctly, you can actually move your teeth in the wrong direction.
Important Note from the Author: Online retainers are best for replacing a retainer that you already know fits well. They are not recommended for your very first retainer after braces unless a dentist approves the fit in person.
Option 4: FSA or HSA Funds
If you have a Flexible Spending Account (FSA) or Health Savings Account (HSA) through your job, you can use those pre-tax dollars to pay for retainers. This does not lower the price, but it effectively gives you a discount equal to your tax rate (typically 20% to 30%).
Step-by-Step: What to Expect at Your Retainer Appointment
Knowing what happens during a retainer visit helps you understand why the dental code costs what it does. Let us walk through a typical appointment for upper and lower removable retainers using code D8680.
Step 1: The Exam (15 minutes)
Your dentist will check your teeth and gums. They want to make sure your teeth have not shifted too much since you finished braces. If your teeth moved a lot, a simple retainer might not fit. You may need a few months of clear aligners again first.
Step 2: Impressions or Digital Scan (10 minutes)
This is where the magic happens. The dentist takes a perfect mold of your upper teeth and your lower teeth. Traditional impressions use a tray with gooey alginate material. Digital scans use a small wand that takes hundreds of photos per second to build a 3D model on a computer screen.
Digital scans are more comfortable and faster, but they cost the dentist more money upfront. That is why digital scan offices sometimes charge higher fees for D8680.
Step 3: Lab Work (1 to 2 weeks)
Your molds or scans go to a dental lab. A technician creates your retainers. For Hawley retainers, they pour stone models, bend wire, and cure acrylic. For clear retainers, they vacuum-form a sheet of plastic over the model and trim it.
Step 4: Delivery and Fitting (20 minutes)
You return to the office. The dentist places the upper retainer in your mouth. They check for pressure points, sharp edges, and proper fit. They do the same for the lower retainer. They will show you how to insert and remove them correctly. You will practice in the office.
Step 5: Adjustments (5 minutes, sometimes same day)
If a retainer feels too tight or digs into your gums, the dentist makes small adjustments. For clear retainers, they might trim the plastic. For Hawley retainers, they adjust the wire clasps.
All of these steps are included in the D8680 fee. You should not see separate charges for impressions, lab fees, or adjustments unless you signed a very unusual payment agreement.
When the Dental Code Changes: Repairs, Adjustments, and Emergencies
Retainers break. Wires snap. Plastic cracks. Teeth shift. When these things happen, you are looking at different codes.
Code D8690: Repair of a Retainer
If your Hawley retainer’s wire breaks or the acrylic cracks, your dentist can often repair it rather than replace the whole thing. Code D8690 covers this repair.
Repairs are much cheaper than replacements. Expect $75 to $150 per repair. If both your upper and lower retainers need repairs, you will likely see D8690 billed twice.
However, there is a limit. If the retainer is more than three years old, the plastic is probably brittle, and the repair may not hold. Your dentist will honestly tell you whether a repair is worth it or if you need a full replacement (D8697).
Adjustments for Tight or Loose Retainers
If your retainer feels tight after not wearing it for a while, a simple adjustment might fix it. Many dentists do not bill for a quick adjustment if you are an existing patient. They just help you out during a brief appointment.
But if the adjustment requires significant reshaping or new wire bends, the dentist may bill D8690.
Emergency Retainer Situations
Your retainer breaks the night before a vacation. You lose your retainer on a business trip. These situations happen. Many dental offices keep emergency appointment slots open. The code is still D8690 or D8697, but you may pay an additional “emergency fee” of $50 to $100 for the after-hours or same-day appointment.
A Complete Comparison: Hawley vs. Essix vs. Fixed Retainers
To fully understand why the dental code for upper and lower retainers matters, you need to know which type of retainer is right for you. Each has different costs, durability, and billing rules.
| Feature | Hawley (Wire + Acrylic) | Essix (Clear Plastic) | Fixed (Bonded Wire) |
|---|---|---|---|
| CDT Code | D8680 | D8680 | Varies (often D8690 or bundled) |
| Typical Lifespan | 5-10 years | 1-3 years | 5-15 years |
| Visibility | Wire visible across teeth | Nearly invisible | Hidden behind teeth |
| Comfort | Bulky palate, takes time to adjust | Thin and smooth | Feels natural after a few days |
| Speech Impact | Minor lisp for a few days | Temporary lisp | No speech impact |
| Repairability | Easily repairable (D8690) | Not repairable; must replace (D8697) | Not repairable at home; dentist must remove and replace |
| Best For | Patients who grind teeth or need durable long-term wear | Patients who want invisible retention | Patients who will not wear removable retainers reliably |
Which One Do Dentists Prefer?
Most orthodontists recommend a Hawley retainer for the upper arch and a fixed retainer for the lower arch. Why? The lower front teeth are the most likely to relapse (shift back to their original crooked positions). A fixed wire on the lower front teeth guarantees those teeth stay put. The upper front teeth are less likely to relapse dramatically, so a removable Hawley retainer works well.
This combination gives you the best of both worlds: security on the bottom, convenience on the top.
Long-Term Care: Making Your Upper and Lower Retainers Last
You spent good money on these appliances. Here is how to protect that investment.
Daily Cleaning Habits
- Hawley retainers: Brush with a soft toothbrush and non-abrasive toothpaste. Soak once a week in a retainer cleaner like Retainer Brite or plain white vinegar diluted with water (1:3 ratio).
- Essix retainers: Brush gently with a soft brush and plain water or dish soap. Never use toothpaste—it scratches the plastic and makes it cloudy. Soak daily in a gentle cleaner.
- Fixed retainers: Floss under the wire using a floss threader or superfloss. Use a small interproximal brush to clean around the bonding pads.
What Not to Do (Serious Warnings)
Never wrap your retainer in a napkin. This is how thousands of retainers end up in restaurant trash cans every single day. Always put it in its case immediately.
Never leave retainers in a hot car. The heat warps the plastic permanently. Once warped, no adjustment can fix it. You need a full replacement (D8697).
Never soak Essix retainers in mouthwash. Most mouthwashes contain alcohol or dyes that damage clear plastic. Your retainer will turn a weird shade of blue or green and become brittle.
When to Replace Your Retainers
Even with perfect care, retainers wear out. Here are clear signs you need a replacement:
- Visible cracks or holes in the plastic
- Wires that are loose or poking your cheek
- The retainer feels loose even after an adjustment
- Your teeth have started shifting (you notice new gaps or crowding)
Do not wait until your teeth have moved significantly. A minor shift is easy to correct with a new retainer. A major shift might require braces or aligners again, which costs thousands of dollars.
Frequently Asked Questions (FAQ)
1. Is there a single dental code that covers both upper and lower retainers together?
No. Most CDT codes for retainers are designed to be billed per arch. You will typically see two separate charges—one for the upper, one for the lower. Some dentists offer a “package price” for both, but on the insurance claim form, they still list two line items.
2. Does my medical insurance cover retainers after jaw surgery?
Sometimes. If you had orthognathic (jaw) surgery for a medical reason like sleep apnea or difficulty chewing, your medical insurance might cover retainers as part of the post-surgical care. This is rare and requires pre-authorization. Your oral surgeon’s office usually handles this paperwork.
3. Can I use the same dental code for a night guard and a retainer?
No. Night guards (for teeth grinding) use code D9940. Retainers use D8680 or D8697. They are completely different appliances with different purposes. Do not let a dental office bill a retainer as a night guard to trick your insurance—that is insurance fraud.
4. How often should I replace my upper and lower retainers?
Hawley retainers: every 5-10 years. Essix retainers: every 1-3 years. Fixed retainers: They can last 10+ years, but the bonding glue can fail. Have your dentist check the bond at your regular checkups.
5. What if I only need one retainer (upper only or lower only)?
That is completely fine. The dental code does not change. You simply bill one unit of D8680 (or D8697) for the single arch you need. The price is roughly half of the upper-and-lower total.
6. Will my FSA or HSA cover online retainers from a mail-order company?
Yes, generally. As long as you have a letter of medical necessity from a dentist or orthodontist, you can use FSA/HSA funds for online retainers. However, check with your FSA/HSA administrator first—some require a prescription from a licensed provider.
7. Why did my dentist bill D8690 instead of D8680 for my new retainer?
This is unusual but can happen if the dentist considers the retainer a minor modification of an existing appliance rather than a full fabrication. If you see D8690 for a brand new retainer, ask for clarification. It is more likely that a billing error occurred.

Conclusion
Understanding the dental code for upper and lower retainers comes down to two main numbers: D8680 for new removable retainers and D8697 for replacements. Most patients will pay for two separate units—one for the upper arch and one for the lower arch. Insurance coverage varies wildly, so always verify your orthodontic benefits before booking an appointment. By knowing these codes and asking the right questions, you can avoid surprise bills and keep your smile straight for years to come.
