ADA Code for Denture Repair: A Complete, Practical Guide for 2026

If you have ever dropped a denture on a tile floor, you know the sinking feeling that follows. That little crack or a broken tooth can turn a normal day into a stressful search for solutions. Whether you are a dental professional looking for the right billing code or a patient trying to understand a treatment plan, you have likely asked the same question: what is the correct ADA code for denture repair?

Let us be clear from the start. Dental billing can feel like a maze. The American Dental Association (ADA) publishes the Current Dental Terminology (CDT) code set. These codes change, get updated, and sometimes cause confusion. But do not worry. This guide walks you through everything you need to know about denture repair codes in a simple, honest, and practical way. No fluff. No fake codes. Just real, useful information.

Why Knowing the Right Code Matters

Using the wrong code can lead to claim denials, delayed payments, or even audits. For patients, understanding the code helps you read your dental insurance explanation of benefits (EOB) with confidence. You do not need to be a billing expert. You just need a reliable reference.

Let us build that reference together.

The Two Main ADA Codes for Denture Repair

The ADA has two primary codes for repairing a complete or partial denture. They are distinct. They are not interchangeable. Choosing the right one depends entirely on what broke and what the lab needs to do.

Here are the codes you will use most often:

These two codes cover the vast majority of denture repairs in a typical dental office. But there is more to the story. Let us look at each code in detail.

D5511: Repair Broken Complete Denture Base

Imagine a patient walks in. Their lower complete denture snapped in half when they dropped it in the sink. The teeth are fine. The fit is still acceptable. But the pink acrylic base has a clean break.

This is a classic D5511 situation.

What does D5511 include?

• Cleaning and drying the broken fragments

• Realigning the pieces on a model (cast) of the patient’s mouth

• Applying acrylic resin to rejoin the parts

• Reinforcing the repair if necessary (sometimes with metal wire or mesh)

• Finishing and polishing the repaired area so it is smooth and comfortable

What does D5511 not include?

• Replacing teeth (use D5520 for that)

• Relining the denture (different codes apply)

• Adjusting the fit extensively (a separate adjustment code may apply)

A quick note for dentists: some insurance plans bundle a limited adjustment into D5511. Others do not. Always check the patient’s specific plan.

D5520: Replace Missing or Broken Teeth on Denture

Now picture a different scenario. A patient has a partial denture. They were eating popcorn and bit down on an unpopped kernel. One of the front artificial teeth cracked in half. The base is perfectly fine. Only the tooth is damaged.

This requires D5520.

What does D5520 include?

• Removing the damaged tooth or the remaining fragments

• Preparing the space in the denture base

• Selecting a matching tooth shade and shape

• Processing the new tooth into the denture using acrylic

• Finishing and polishing the area

What does D5520 not include?

• Repairing a cracked base (use D5511)

• Adding a clasp or other metal component (different code)

Sometimes both the base and a tooth break at the same time. For example, a denture falls on a hard floor. The base cracks in two places, and a front tooth flies off. In that case, you might need to bill both D5511 and D5520. Many insurance plans allow this. Some do not. We will talk about that later.

Less Common But Still Important Codes

While D5511 and D5520 are the stars of this article, you should know about a few related codes. They are not technically “denture repair” codes, but they often appear on the same treatment plan.

For 99% of everyday denture repairs, you will live in the world of D5511 and D5520.

Real-World Scenarios: Which Code Should You Pick?

Let us walk through some common situations. Read each one and think about the code. Then check the answer.

Scenario 1: A patient brings in an upper complete denture. One of the back molar teeth is worn down flat but not cracked. The patient wants a new tooth built up in that spot.

• Answer: D5520. Worn teeth count as missing tooth structure. Even if the tooth is still partially there, the procedure is a replacement.

Scenario 2: The denture base has a hairline crack that leaks saliva underneath. It causes soreness. The crack does not go all the way through yet, but it will soon.

• Answer: D5511. A crack is a fracture. Repairing it now prevents a full break later. Most dentists and insurers agree on this.

Scenario 3: A partial denture lost a clasp. The acrylic base and teeth are fine.

• Answer: Neither D5511 nor D5520. Clasp repair typically uses D5630 (repair or replace broken clasp). Do not force a denture repair code where it does not belong.

Scenario 4: A complete denture broke into three pieces. Two teeth are missing from the broken section.

• Answer: D5511 (for the base) and D5520 (for the teeth). Some offices combine these into a single line item with a narrative description. Others bill both. We will discuss insurance rules below.

How Insurance Handles Denture Repair Codes

Insurance billing for denture repair is usually straightforward, but there are traps. Let me share what I have learned from talking to office managers and billing specialists.

Frequency Limitations

Most dental insurance plans limit denture repairs to once per denture per 12 to 36 months. Why? Because a denture that breaks repeatedly may need a replacement rather than another repair. Some plans explicitly state: “After two repairs in 24 months, we will only cover a new denture.”

Always check the patient’s plan. Do not assume.

Deductibles and Coinsurance

Repairs are typically subject to the same deductible and coinsurance as other basic services. Many plans cover repairs at 50% to 80% after the deductible. Some cover 100% if the denture is less than five years old. Again, check.

Bundling Rules

Here is where offices get into trouble. Some insurance carriers bundle D5511 and D5520 into a single payment. They say: “You repaired the base and replaced a tooth. That is one repair event. We will pay the higher of the two fees, not both.”

Other carriers pay both codes separately, especially if the work is extensive.

What should you do? Bill both codes separately. Include a clear narrative in box 35 of the ADA claim form. For example: “Denture fractured into three pieces. Two teeth missing from the fractured segment. Base repair (D5511) and tooth replacement (D5520) both required.” Let the insurance company decide. If they deny one, you can appeal or write it off.

What Patients Need to Know About Denture Repair Costs

If you are a patient reading this, you probably want to know one thing: how much will this cost?

I cannot give you a specific dollar amount. Prices vary wildly by location, lab fees, and dentist expertise. But I can give you realistic ranges based on national averages and insurance fee schedules.

A few important notes on pricing:

• Emergency repairs (same-day while you wait) often cost more. Add $50 to $100.

• Laboratory fees are usually included in the office fee. Some offices bill separately. Ask before they start.

• Adjustments after repair may be included or separate. Clarify this upfront.

If you have insurance, your out-of-pocket cost will be your deductible plus your coinsurance percentage of the negotiated fee. For example: Negotiated fee for D5511 is $120. Your plan pays 80% after a $50 deductible. You pay $50 + 20% of $120 ($24) = $74 total.

If you do not have insurance, many dental offices offer in-house discount plans or payment arrangements. Just ask.

Step-by-Step: What Happens During a Denture Repair (Clinical View)

You do not need to be a dentist to understand this. But knowing the steps helps you appreciate why a repair costs what it does.

Step 1: Examination and Assessment (5–10 minutes)

The dentist inspects the broken denture and the patient’s mouth. They check for sharp edges, loose parts, and the overall fit. They also look for problems in the mouth, such as sore spots or infections. A repair on a poorly fitting denture may fail quickly.

Step 2: Laboratory Impressions or Model (Optional)

For a simple crack, the dentist might repair it directly. For a complex break, they take an impression of the denture and the patient’s arch. They pour a stone model. The model holds the broken pieces in perfect alignment while the acrylic cures.

Step 3: Preparing the Surfaces

The technician roughens the broken edges. They clean away oil, saliva, and old acrylic dust. This step is critical. If the surfaces are not clean, the new acrylic will not bond.

Step 4: Applying Acrylic and Curing

They apply a monomer liquid and polymer powder (denture repair acrylic). For a D5511, they join the pieces and clamp them together. For a D5520, they pack acrylic around a replacement tooth. Then they let it cure. Some offices use a pressure pot. Others use a heat cure or a cold cure. All methods work if done correctly.

Step 5: Finishing and Polishing

Once the acrylic hardens, they trim excess material. They shape the repair to match the original contour. Then they polish it to a smooth, non-porous finish. A rough repair harbors bacteria and irritates gums.

Step 6: Delivery and Adjustment (10–15 minutes)

The patient tries on the repaired denture. The dentist checks the fit, the bite, and comfort. They make small adjustments with a bur or acrylic trimmer. Then the patient goes home with care instructions.

Total time: 24 to 48 hours for a lab-processed repair. 1 to 2 hours for an in-office emergency repair.

Can You Repair a Denture at Home? (And Why You Should Not)

I see this question all the time in online forums. “Can I just use super glue?”

Please do not.

Here is why home repairs are dangerous:

• Toxicity. Household glues and even “denture repair kits” from the pharmacy often contain chemicals that leach into your saliva. You swallow them.

• Poor fit. A 1-millimeter misalignment changes your bite. That leads to jaw pain, headaches, and damaged remaining teeth.

• Irritation. Rough, unpolished acrylic acts like sandpaper on your gums. You will develop sore spots, infections, or ulcers.

• Future repairs become impossible. Denture acrylic bonds to itself. Super glue creates a film that prevents a proper dental acrylic repair later. The technician may have to cut away more material or discard the denture entirely.

If a repair kit were truly safe and effective, dental offices would sell them instead of performing D5511 and D5520. They do not. That tells you everything.

How to Extend the Life of Your Denture and Avoid Repairs

A well-made denture can last five to ten years or more. But repairs are often preventable. Follow these simple rules.

• Always handle your denture over a soft surface. Fill the sink with water or lay down a folded towel. A fall onto a hard counter or tile floor is the number one cause of breaks.

• Clean your denture over a basin of water. If you drop it, the water cushions the impact.

• Never sleep in your denture. Nighttime wear accelerates bone loss, which changes the fit. A poorly fitting denture flexes more and breaks easier.

• Soak your denture in water or a mild solution when not in use. Drying out makes acrylic brittle.

• Visit your dentist yearly for a fit check. A simple reline (D5750 or D5760) can prevent excessive stress on the base.

• Do not use bleach. Bleach whitens but also weakens acrylic. Use only products designed for dentures.

Documentation and Claim Filing Tips for Dental Offices

For billing professionals and dentists, proper documentation is your best friend. Here is what to include in every denture repair claim.

On the claim form (ADA 2024 or later):

• Box 32: Place of service (usually 11 for office)

• Box 34: The appropriate CDT code (D5511 or D5520)

• Box 35: A clear narrative. Examples:

  • “Complete denture upper – midline fracture through base. No teeth missing.”

  • “Partial denture lower – tooth #24 fractured completely. Base intact.”

• Box 36: Date of service (the day you completed the repair, not the day the patient came in)

• Box 45: Fee for each procedure

In the patient’s chart:

• A photo of the broken denture before repair (highly recommended)

• A copy of the lab slip (if sent out)

• A note that the patient received home care instructions

This documentation protects you if the insurance company audits the claim or if the patient disputes the service.

Common Mistakes and How to Avoid Them

Let me save you some headaches. These are the most frequent errors I see with ADA codes for denture repair.

When Repair Is Not the Answer: Replacement vs. Repair

Sometimes the kindest thing you can tell a patient is: “We should replace this denture instead of repairing it.”

When should you recommend replacement?

• The denture is more than seven years old and has broken twice before.

• The acrylic is discolored, porous, or has a foul odor (signs of degradation).

• The patient has lost significant bone or gum tissue. A repair will not fix the poor fit.

• The cost of repair plus a reline is close to the cost of a new denture.

• The denture has multiple cracks or missing teeth (three or more).

A new complete denture (ADA codes D5110 for upper, D5120 for lower) costs significantly more than a repair. But if the denture is failing in multiple ways, repairs become a losing game. You patch one spot, and another breaks two months later.

Be honest with the patient. Show them the math. “A repair is $200. But your denture needs a reline ($150) and two tooth replacements ($100 each). That is $450. A new denture is $900 and will last five to seven years. Which makes more sense to you?”

How to Find a Reliable Denture Repair Provider

If you are a patient looking for someone to repair your denture, here is what to look for.

Ask these questions before booking:

1. “Do you perform denture repairs in-office, or do you send them to a lab?” (In-office is faster. Lab is often higher quality.)

2. “What is your typical turnaround time?” (Same-day is rare but exists. 24–48 hours is normal.)

3. “Does your fee include adjustments after the repair?” (Some do. Some charge extra.)

4. “Do you use ADA codes D5511 and D5520 on insurance claims?” (If they look confused, walk away.)

5. “Can I see before-and-after photos of previous repairs?” (A confident technician will show you.)

Where to look:

• Private general dentists (most common)

• Denture clinics or denture specialists (often faster)

• Dental schools (slowest but cheapest)

• Some dental laboratories (only in states that allow direct-to-lab repairs; not all do)

Avoid any provider who guarantees a repair without seeing the denture first. Every break is different. A responsible professional inspects before quoting.

The Future of Denture Repair Codes

The ADA updates CDT codes every year or two. As of 2026, D5511 and D5520 remain active and unchanged. But there is talk in coding committees about adding a code for “digital denture repair.” Why? Because 3D-printed dentures use different materials and repair techniques than traditional heat-cured acrylic.

If you work with digital dentures today, check with your payer. Some ask you to use the existing codes with a narrative. Others have internal guidelines. No separate digital repair code exists yet, but watch for one in the 2027 or 2028 CDT manual.

Until then, D5511 and D5520 are your reliable workhorses.

Important Notes for Readers

Note for dental professionals: Always verify patient eligibility and plan benefits before performing a denture repair. Some HMO and discount plans exclude repairs entirely or require prior authorization.

Note for patients: If your denture breaks on a weekend or holiday, do not panic. Most emergency dentists can perform a temporary repair (often using D5511 or D5520 with a “same-day” modifier). Call ahead to confirm.

Note for billers: When submitting a claim for D5520, include the tooth number and surface (if applicable) in the narrative. Example: “Replaced tooth #8 on upper complete denture. Tooth was fractured horizontally.”

Note on warranties: Some denture providers offer a free repair warranty for 6 to 12 months after delivery. If your denture is still under warranty, the office may not bill insurance. They may just perform the repair at no charge. Ask before paying anything.

Real Patient Questions (Answered Honestly)

Q: My denture cracked. The dentist says D5511. My insurance says they only cover D5511 once every two years. Is that normal?
A: Yes, that is common. Many plans impose frequency limitations. If you already used your one repair, you can either pay out of pocket or ask about replacing the denture if it is old.

Q: Can I bill D5520 if the patient lost a tooth but still has the original tooth (it popped out intact)?
A: Technically, yes. The code is for “replace missing or broken teeth.” Even if you reattach the original tooth, you are still performing a replacement procedure. Some dentists use a different code (D5511 with a narrative) for simple reattachment. When in doubt, choose D5520. It is safer for compliance.

Q: My lab charges me a separate fee for a “rush” repair. Can I bill the patient for that?
A: Yes, but not as an ADA code. The rush fee is a separate line item on the patient statement. Insurance does not cover expedited service fees. Just be transparent. Tell the patient: “The standard repair is $150. If you need it today, the lab adds a $50 rush fee. Your insurance will not pay the rush fee.”

Q: I am a patient on Medicaid. Does Medicaid cover D5511 or D5520?
A: It depends entirely on your state. Some state Medicaid programs cover denture repairs. Many do not. Call your Medicaid dental benefit manager and ask specifically for “CDT codes D5511 and D5520.” Do not accept a general “yes” or “no.” Ask for the policy in writing if possible.

Conclusion

Choosing the correct ADA code for denture repair comes down to two simple questions: is the base broken (D5511), or are the teeth broken (D5520)? Use these codes correctly to avoid claim denials, bill fairly, and help patients understand their treatment. When in doubt, document thoroughly, add a clear narrative, and always put patient safety over convenience.

Frequently Asked Questions (FAQ)

1. What is the most common ADA code for denture repair?
D5511 (repair broken complete denture base) and D5520 (replace missing or broken teeth) are the two most common codes. D5511 is slightly more frequent because base cracks happen often from drops or normal wear.

2. Can I use D5511 for a partial denture?
Yes, many offices use D5511 for both complete and partial denture base repairs. Some payers prefer D5610 for resin partials. Check your specific plan. When in doubt, D5511 is widely accepted.

3. How much does a denture repair cost without insurance?
Expect to pay between $100 and $250 for D5511 and $75 to $150 per tooth for D5520. Emergency or same-day repairs add $50 to $100.

4. Does Medicare cover denture repairs?
Original Medicare (Parts A and B) does not cover dentures or denture repairs. Some Medicare Advantage (Part C) plans offer dental benefits that may include repairs. Review your plan’s Evidence of Coverage document.

5. How long does a typical denture repair take?
In-office repairs: 1 to 2 hours. Lab repairs: 24 to 48 hours. Emergency same-day repairs are possible but less common.

6. What happens if I use the wrong ADA code?
The insurance company will either deny the claim, downcode it to a different code (often with lower reimbursement), or request medical records. In some cases of intentional miscoding, audits and penalties can occur.

7. Can a denture be repaired more than once?
Yes, but each repair slightly weakens the surrounding acrylic. Most dentists recommend no more than two or three repairs before replacing the denture entirely.

8. Is there a warranty on denture repairs?
Most dental offices offer a 30- to 90-day warranty on repairs. If the same spot breaks again within that window, they will redo it at no charge. Ask about the warranty policy before proceeding.

9. What is the difference between D5511 and D5610?
D5511 is for a complete denture base. D5610 is specifically for a resin partial denture base. In practice, many dentists use D5511 for both. Check your payer’s preference.

10. Where can I see the full list of current ADA codes?
The ADA publishes the CDT manual annually. You can purchase it or access it through many dental billing software platforms. The free online summary is not always complete. Use the official ADA resource link provided above.
