The Complete Guide to the Dental Code for Bridge Removal (D6791 & D6790)

So, you’ve been told that your dental bridge needs to come out. Maybe it’s loose, maybe a tooth under it is causing trouble, or perhaps it’s simply time for an upgrade. Whatever the reason, you’ve probably started looking into the logistics, and you’ve stumbled upon a confusing string of numbers: the dental code for bridge removal.

Don’t worry, you’re not alone in feeling a bit lost. Dental coding can feel like a secret language spoken only by insurance companies and billing coordinators. But understanding the basics, especially the codes your dentist will use, can make a huge difference. It helps you know what to expect on your treatment plan, estimate your out-of-pocket costs, and have a more informed conversation with your dental office.

This guide is here to translate that language for you. We’ll walk through everything you need to know about the dental codes for bridge removal, what they mean, why one code might be used over another, and what the entire process looks like from start to finish. Consider this your friendly, reliable roadmap to navigating this dental procedure.

Decoding the Mystery: What is a Dental Procedure Code?

Before we dive into the specific numbers, let’s take a quick step back. What exactly are these codes?

Dental procedure codes, officially known as Current Dental Terminology (CDT) codes, are the universal language of dentistry in the United States. Maintained by the American Dental Association (ADA), these five-character alphanumeric codes (always starting with the letter “D”) describe a specific dental procedure. When your dentist says, “You need a crown,” they then translate that into a code (like D2740) for your insurance company.

This system ensures that your insurance provider knows exactly what procedure was performed. It’s the foundation of your dental claim and determines how much of the cost they will cover.

For you, the patient, seeing these codes on a treatment plan is like looking under the hood of a car. It provides a clear, itemized list of the work to be done. And when it comes to a complex procedure like bridge removal, knowing the code is the first step to understanding the financial side of things.

The Main Event: The Primary Dental Code for Bridge Removal

When you need to have an existing bridge taken off, there isn’t just one single code that fits every situation. The code your dentist uses depends on why the bridge is being removed and what will happen next.

However, there is one code that is most commonly used for the straightforward removal of a bridge. The primary dental code for bridge removal is:

D6791: Removal of Fixed Partial Denture (Bridge)

This is the code you will see most often. The American Dental Association defines D6791 as the “removal of fixed partial denture.” This applies when the entire bridge—the artificial teeth (pontics) and the crowns on the abutment teeth—is taken off in one piece.

Think of this as the “standard” removal. The bridge is intact, and the dentist is carefully cutting or grinding away the dental cement that holds it in place to lift it off the supporting teeth. The key here is that the bridge itself is not being destroyed in the process, although it is unlikely to be reusable afterward due to the force required for removal.

When is D6791 used?

• The bridge is loose and needs to be removed to recement it.

• There is minor decay on a supporting tooth that can be treated without replacing the entire bridge.

• A tooth under the bridge needs root canal therapy, and the bridge must come off to access it.

• You are replacing the bridge with a new one, but the dentist needs to assess the health of the abutment teeth first.

In most of these cases, once the issue is resolved, the same bridge may or may not be able to be re-cemented. Often, the removal process weakens it, or the dentist finds an issue that requires a new restoration. But the procedure code D6791 simply describes the act of taking it off.

The Alternative: When a Bridge is Cut Off

There’s another, more involved code you should know about. It’s used when a simple removal isn’t possible or practical.

D6790: Removal of Fixed Partial Denture (Bridge) – Sectioned

This code describes a more complex procedure. “Sectioning” a bridge means the dentist has to cut the bridge into pieces to remove it. This is necessary when a bridge is exceptionally strong, when one of the supporting teeth is severely broken or decayed, or when the bridge is permanently cemented (which is most common) and won’t budge with normal removal attempts.

Why would a dentist need to section a bridge?

• To preserve tooth structure: Attempting to yank a bridge off with excessive force could fracture the healthy teeth underneath. Cutting the bridge allows for a gentler, more controlled removal of each individual crown.

• To access a damaged tooth: If one of the abutment teeth is badly broken down, sectioning the bridge allows the dentist to remove the portion over that tooth separately and assess the damage.

• The bridge is too strong: Some metal or zirconia bridges are incredibly resilient. It’s safer and faster to cut through the material than to try to break the cement bond holding it in place.

D6791 vs. D6790: A Quick Comparison

To make the difference crystal clear, let’s look at a simple comparison.

The Complete Process: From Consultation to Removal

Knowing the codes is one thing, but understanding what actually happens during the appointment can alleviate a lot of anxiety. Here’s a step-by-step look at a typical bridge removal procedure.

Step 1: The Pre-Removal Consultation and Exam

Before any work begins, your dentist will perform a thorough examination. This usually involves:

• Visual Inspection: Checking the bridge for visible cracks, loose areas, and the health of the surrounding gums.

• X-rays: This is a critical step. X-rays show what’s going on underneath the bridge. They can reveal decay under the crowns, bone loss around the roots of the abutment teeth, or issues with a previous root canal. These images help the dentist decide if removal is necessary and whether D6791 or D6790 is more appropriate.

• Discussion of Options: Your dentist will explain why the bridge needs to come off and discuss the options for what happens after removal. Will a new bridge be made? Is a dental implant a possibility? This is the time to ask all your questions.

Step 2: The Removal Appointment

The day of the procedure, you can expect the following:

1. Anesthesia: The dentist will apply topical anesthetic to numb your gums, followed by local injections around the abutment teeth. You should not feel any pain, only pressure and vibration.

2. The Removal: This is where the chosen code comes into play.

   • If the code is D6791, the dentist will use a high-speed handpiece (drill) to carefully cut through the cement that bonds the bridge to your teeth. They use special instruments to gently wiggle and lift the bridge off. The goal is to remove it intact.

   • If the code is D6790, the dentist will use a small, precise drill to cut a groove down the middle of the bridge, essentially splitting it into two halves. Each crown can then be removed individually. You will hear more drilling, but the sensation should be no different from getting a filling.

3. Temporary Protection: Once the bridge is off, the underlying teeth are exposed and vulnerable. They may be sensitive and are at risk of shifting. Your dentist will almost always place a temporary bridge or individual temporary crowns to protect them and maintain the space while you decide on the next step.

Step 3: What Happens Next? (The “After” Plan)

The removal is rarely the final step. It’s the gateway to the next phase of your treatment. Common next steps include:

• New Bridge: Impressions are taken to create a new, permanent bridge. You’ll wear your temporaries for a few weeks while the new one is being fabricated in a dental lab.

• Implant Placement: If you’re replacing the bridge with implants, the dentist may extract the old abutment teeth (if they are failing) and place the implant posts during the same visit or after a healing period.

• Repair and Re-cementation: In a best-case scenario, if the old bridge is in good shape and the underlying teeth just needed a small filling or a recement, the dentist might clean everything up and reattach your original bridge on the same day. This is becoming less common as bridges are often weakened by removal.

The Financial Picture: What Will This Cost?

This is the part everyone worries about. The cost of a bridge removal varies widely, but understanding the codes gives you a solid foundation for asking your dental office the right questions.

Average Costs for D6791 and D6790

• D6791 (Standard Removal): The cost for a standard bridge removal can range from $150 to $350 per bridge.

• D6790 (Sectioned Removal): Because it is more time-consuming and requires greater skill, the cost for sectioning a bridge is higher. You can expect it to range from $250 to $500 or more per bridge.

Important Note: These are ballpark figures. Your actual cost will depend on your geographic location, the specific dentist’s fees, and the complexity of your case. A bridge spanning multiple teeth will be more expensive to remove than a simple three-unit bridge.

How Dental Insurance Typically Handles Bridge Removal

This is where things can get a little tricky. Dental insurance policies vary greatly, but here are the general rules of thumb:

• It’s Usually Covered: The removal of a bridge is generally considered a necessary dental procedure, not a cosmetic one. Therefore, most insurance plans will provide some level of coverage.

• Benefit Category: Bridge removal typically falls under “Major Restorative” care. Most plans cover Major services at a lower percentage than basic services like fillings. A common coverage split is 50% for Major, meaning the insurance pays half, and you pay the other half.

• The Deductible: You will likely have to meet your annual deductible (often $50-$100) before your insurance begins to pay.

• The “Two-Bridge” Problem: This is important. If you are having a bridge removed to replace it with a new bridge, the cost of the removal (D6791) is often a separate, billable procedure. The new bridge will have its own set of codes and costs. You are essentially paying for two procedures, even though they happen at the same appointment. However, some dentists may bundle this into a “removal and remake” fee. Always ask for a detailed breakdown.

• The “Cut-Off” Clause: Some insurance contracts have specific clauses about “sectioning” crowns or bridges. It’s best to assume that your insurance will cover the most appropriate procedure for your situation, and your dentist’s office will justify D6790 if it was clinically necessary.

How to Get an Accurate Estimate

The best way to avoid surprises is to ask your dental office for a pre-determination of benefits (also called a pre-authorization). They will send the planned codes (like D6791 and the code for your future crown or bridge) to your insurance company, who will then send you a statement outlining exactly what they will pay and what your portion will be. This isn’t a guarantee of payment, but it is a highly reliable estimate.

Understanding Dental Bridge Materials and Their Impact on Removal

The material your bridge is made from can actually influence how easy or difficult it is to remove, and therefore, which code is used.

• Porcelain-Fused-to-Metal (PFM): These are very common. The porcelain can be brittle. During removal, there’s a risk of the porcelain chipping or shattering, which might necessitate sectioning (D6790).

• All-Metal (Gold): Gold is a soft, malleable metal. These bridges can sometimes be gently pried off with less risk of damage to the underlying tooth, making standard removal (D6791) more likely.

• All-Ceramic/Zirconia: These are the newest and strongest materials. They are incredibly tough and bonded with extremely strong cement. Because they are so hard, attempting to remove them in one piece can be very difficult and risky. Dentists often opt to section (D6790) these right from the start to ensure a safe and predictable procedure.

Common Reasons for Bridge Removal

Why go through all this? Here are the most common reasons a dentist will recommend removing an existing bridge.

• Recurrent Decay: This is the number one enemy of dental bridges. Decay can form at the margin where the crown meets the tooth, especially if flossing isn’t consistent. Once decay reaches a certain depth, the bridge must come off to treat the tooth.

• Failed or Fractured Bridge: The bridge itself can break. The porcelain can chip, the metal framework can crack, or a pontic (fake tooth) can fracture.

• Cement Failure: The dental cement holding the bridge in place can wash out over time, making the bridge feel loose and trap food and bacteria underneath.

• Gum Disease: Advanced gum disease can lead to bone loss around the abutment teeth, compromising the support for the bridge.

• Need for Root Canal Therapy: An abutment tooth may develop an infection that requires a root canal. To perform the procedure effectively, the dentist often needs to remove the bridge to access the top of the tooth.

• Aesthetic Upgrade: Sometimes, a patient simply wants to replace an older, unsightly bridge with a newer, more natural-looking one.

Recovery and Aftercare Following Bridge Removal

Good news: recovering from a bridge removal itself is usually quick and straightforward.

• Immediate Aftermath: Your gums may be a little sore, and the teeth that were under the bridge might be sensitive to temperature and air, especially if they were shaved down.

• Pain Management: Over-the-counter pain relievers like ibuprofen or acetaminophen are usually sufficient to manage any discomfort.

• Eating: Stick to soft foods for the first 24-48 hours. Avoid anything sticky, hard, or chewy that could dislodge your temporary bridge.

• Oral Hygiene: You must keep the area clean, but be gentle. Brush carefully around the temporaries and floss as instructed by your dentist (often by gently threading floss through and sliding it out, rather than snapping it up).

• When to Call the Dentist: If your temporary comes off, if you experience severe pain, or if you notice signs of infection (swelling, pus), contact your dental office immediately.

Important Note: The long-term recovery and care will depend on the next procedure, whether that’s a new bridge, implants, or another option. Your dentist will give you specific instructions for that phase of your treatment.

Frequently Asked Questions (FAQ)

Q: Is bridge removal painful?
A: No, it shouldn’t be. You will receive local anesthetic to numb the area completely. You will feel pressure and vibration from the dental drill, but not sharp pain. If you feel any pain, you should raise your hand immediately so the dentist can give you more anesthetic.

Q: Can a dentist remove a bridge and put it back on?
A: It is possible but not common. The process of removing a bridge often damages it slightly or weakens the structure. It’s more typical for a bridge to be removed because it needs to be replaced, or for it to be removed to allow for treatment of the teeth underneath, after which a new bridge is made.

Q: How long does it take to remove a dental bridge?
A: A standard removal (D6791) can take anywhere from 15 to 30 minutes. A sectioned removal (D6790) can take 30 to 60 minutes or longer, depending on the material and number of units.

Q: Will my insurance cover the cost of bridge removal?
A: Most dental insurance plans do cover a portion of the cost, as it is considered a medically necessary procedure. It usually falls under major restorative care, often with 50% coverage after your deductible. A pre-determination of benefits is the best way to know for sure.

Q: What is the difference between D6790 and D6791?
A: D6791 is the code for removing a bridge in one piece. D6790 is the code for removing a bridge by cutting it (sectioning) into pieces. D6790 is a more complex procedure used for bridges that are very tightly cemented or when a tooth is compromised.

Q: Can I eat after having a bridge removed?
A: You should wait until the numbness wears off completely to avoid biting your cheek or tongue. Once the feeling returns, stick to soft foods and avoid chewing on the side of the removal until you get your temporary restoration.
