If you have ever needed a tooth replaced, you have probably heard the term “bridge.” But before that final bridge is ready, many patients wear a temporary bridge. This raises an important question for both dental billers and curious patients: What is the correct dental code for a temporary bridge?
The answer is not always a single number. It depends on how the temporary is made and where it sits in your mouth.
In this guide, we will walk through everything you need to know. We will cover the specific codes, when to use them, what insurance typically covers, and common mistakes to avoid. Whether you are a dental office manager, a new patient, or a student, this article will give you a clear, honest understanding of temporary bridge coding.
Let us start with the basics.
What Is a Temporary Bridge and Why Do You Need One?
A temporary bridge is a provisional restoration. Think of it as a placeholder. While your permanent bridge is being custom-made in a dental lab, the temporary bridge protects your teeth and gums.
The Main Jobs of a Temporary Bridge
- Protects exposed dentin and nerves from temperature and pressure.
- Maintains space so your adjacent teeth do not shift.
- Preserves chewing function on a basic level.
- Provides aesthetics so you can smile confidently during the waiting period.
- Protects gum tissue and allows proper healing if teeth were extracted.
Without a temporary bridge, your prepared teeth would be vulnerable. They could become sensitive, shift out of position, or even get damaged.
How Long Do You Wear a Temporary Bridge?
Most patients wear a temporary bridge for two to four weeks. In complex cases, it could be longer. Your dentist will give you specific care instructions. These usually include avoiding sticky or hard foods on that side of your mouth.
Now, let us get to the main question.
The Primary Dental Code for a Temporary Bridge
After reviewing the most current CDT (Current Dental Terminology) codes, there is no single code labeled “temporary bridge” in the simplest sense. Instead, dentists use two main codes depending on the situation.
Here are the correct dental codes for a temporary bridge:
| CDT Code | Official Description | When to Use |
|---|---|---|
| D6970 | Post and core in addition to crown, indirectly fabricated | When a temporary bridge replaces a single tooth with a custom post and core |
| D6972 | Post and core in addition to crown, prefabricated | When a temporary bridge uses a prefabricated post and core |
Wait — those descriptions mention “post and core.” That can be confusing. Let me explain clearly.
In many cases, a temporary bridge is not billed as a separate “bridge” code. Instead, it is included in the fee for the permanent bridge. However, when a temporary bridge requires additional work — like a post and core to hold it in place — you use D6970 or D6972.
So What If No Post and Core Is Needed?
If the temporary bridge is a simple acrylic provisional placed directly after tooth preparation, it is typically bundled into the permanent bridge code (D6740 for porcelain/ceramic or D6750 for porcelain fused to metal). That means you do not bill separately.
But many dental offices need to bill for a complex temporary bridge. In those cases, here is the most accurate approach:
- Use D6970 for a custom-made post and core supporting a temporary bridge.
- Use D6972 for a prefabricated post and core supporting a temporary bridge.
D6970 vs D6972: Which One Should You Use?
Choosing between D6970 and D6972 depends on how the post and core are made. Let us break this down in simple terms.
D6970 – Indirectly Fabricated Post and Core
This code means the post and core are custom-made in a dental lab. The dentist takes an impression of the prepared tooth. A technician fabricates a post and core that fits perfectly.
When to choose D6970:
- The tooth has an unusual shape or large decay.
- You need maximum strength for a long-term temporary.
- The temporary bridge will be worn for more than four weeks.
D6972 – Prefabricated Post and Core
This code uses a ready-made post. The dentist selects the size, cements it into the root canal, and builds a core around it.
When to choose D6972:
- The tooth has a straightforward root canal shape.
- The temporary bridge is short-term (two to three weeks).
- Cost is a major factor for the patient.
Here is a quick comparison table:
| Feature | D6970 (Indirect) | D6972 (Prefabricated) |
|---|---|---|
| Fabrication location | Dental lab | In-office or lab |
| Customization level | High | Moderate |
| Typical chair time | Two visits | One to two visits |
| Strength | Very high | Good |
| Cost to patient | Higher | Lower |
| Best for | Complex cases | Simple cases |
Important Note: Neither D6970 nor D6972 is a “temporary bridge” code by name. But in practice, these are the codes used when a temporary bridge requires additional support. Always check with the patient’s insurance before submitting claims.
What About the “Interim Prosthesis” Codes?
You might see codes like D5820 (interim partial denture) or D5821. These are different. An interim partial denture replaces multiple teeth but is not the same as a temporary bridge.
A temporary bridge is cemented onto prepared natural teeth. An interim partial denture is removable.
So, do not use D5820 for a cemented temporary bridge. That would be incorrect billing.
Step-by-Step: How a Dentist Bills for a Temporary Bridge
Let us walk through a real-world example. This will help you understand exactly what happens at the dental office and what appears on your insurance claim.
Scenario A: Simple Temporary Bridge (No Post and Core)
- The dentist prepares two abutment teeth for a three-unit bridge.
- They take an impression for the permanent bridge.
- They make a temporary acrylic bridge chairside.
- They cement the temporary bridge.
Billing: No separate code. The temporary bridge is included in the permanent bridge fee (D6740 or D6750). The patient pays one global fee.
Scenario B: Temporary Bridge with a Prefabricated Post and Core
- One abutment tooth has had a root canal and needs a post.
- The dentist places a prefabricated post (D6972).
- They build a core and then fabricate the temporary bridge.
- They cement the temporary bridge.
Billing: D6972 plus the permanent bridge code (to be billed later). The temporary bridge itself is still not separate, but the post and core are.
Scenario C: Complex Temporary Bridge with Custom Post and Core
- The abutment tooth is severely damaged.
- The dentist takes an impression for a custom post and core.
- The lab fabricates the post and core (D6970).
- At the next visit, the dentist seats the post and core, then places the temporary bridge.
Billing: D6970 plus the future permanent bridge code.
What Insurance Usually Covers for a Temporary Bridge
Insurance can be tricky. Here is an honest look at what most dental PPO plans do.
- Temporary bridge without post and core: Usually not billed separately. It is considered part of the permanent bridge procedure. Insurance will only pay once for the permanent bridge.
- Temporary bridge with D6972 (prefabricated): Often covered at 50-80% of the allowed amount, depending on the plan.
- Temporary bridge with D6970 (indirect): May be covered, but some plans consider it a “non-covered service.” Always verify.
A Note on Deductibles and Frequencies
Most insurance plans have a once-per-five-year rule for bridges. That applies to the permanent bridge, not the temporary. However, if you bill D6970 or D6972, those codes have their own frequency limitations. Usually, one post and core per tooth per three to five years.
Reader Tip: If you are a patient, ask your dentist’s billing coordinator to run a pre-authorization before starting treatment. This will tell you exactly what your plan covers for the temporary bridge components.
Common Billing Mistakes to Avoid
Even experienced dental billers can make errors with temporary bridge codes. Here are the most common ones.
Mistake #1: Using D6970 for a Simple Temporary
Some offices think D6970 is the “temporary bridge code.” It is not. Using it for a simple acrylic temporary is incorrect. It could trigger an audit or a denied claim.
Mistake #2: Billing a Separate Code for the Acrylic Temporary
Do not create a code like “D9999 – temporary bridge.” That is an unspecified code. Most insurances will deny it. Only use unspecified codes in rare, truly unique situations.
Mistake #3: Forgetting the Permanent Bridge Code
The temporary is only half the story. Make sure you also bill the permanent bridge code (D6740, D6750, D6720, etc.) on the correct date of service.
Mistake #4: Not Documenting Medical Necessity
Insurance companies want to know why a post and core were needed. Always include:
- Periapical X-rays showing the need.
- A narrative describing the tooth condition.
- Periodontal charting if relevant.
How Patients Can Prepare for Temporary Bridge Costs
If you are reading this as a patient, you might feel overwhelmed. Do not worry. Here is a simple checklist.
Before Treatment:
- Ask your dentist if a temporary bridge will be needed.
- Ask if a post and core will be required.
- Request a written treatment plan with all CDT codes.
- Call your insurance to verify coverage for D6970 or D6972.
- Ask about your permanent bridge coverage (usually 50% after deductible).
After Treatment:
- Review your explanation of benefits (EOB).
- Make sure the codes match what you discussed.
- If a claim is denied, ask your dentist to appeal with X-rays and notes.
Real Patient Questions About Temporary Bridge Codes
“My dentist says the temporary bridge is free. Is that true?”
Not exactly. It is not “free.” It is included in the total fee for your permanent bridge. So you are paying for it, but there is no separate line item. That is standard practice.
“Why did my insurance deny D6970?”
Common reasons:
- No X-ray evidence of a broken-down tooth.
- The plan excludes indirect post and cores.
- The frequency limit has been met (another post was done recently).
“Can I get a temporary bridge without a permanent one?”
No. A temporary bridge is always part of a permanent bridge treatment plan. You cannot get a temporary bridge alone.
Documentation Best Practices for Dental Offices
Good documentation protects you in an audit. Here is what your patient chart should include when billing a temporary bridge with D6970 or D6972.
- Pre-op X-ray showing the condition of the abutment tooth.
- Post-op X-ray showing the post and core in place.
- Treatment note describing why a post was necessary (e.g., “Tooth #19 has less than 2mm of coronal structure remaining”).
- Lab slip for D6970 cases (showing the indirect fabrication).
- Informed consent signed by the patient.
Without these, an insurance auditor may recoup the payment.
Temporary Bridge Codes for Different Situations
Let us look at a few clinical scenarios. Each one uses codes slightly differently.
| Clinical Situation | Correct Code(s) | Explanation |
|---|---|---|
| 3-unit temporary, no posts | Included in D6750 | No separate code |
| 3-unit temporary, one prefab post | D6972 + D6750 | Post billed separately |
| 3-unit temporary, one custom post | D6970 + D6750 | Custom post billed separately |
| 4-unit temporary, two prefab posts | D6972 (x2) + D6750 | Two separate post codes |
| Temporary on implant abutment | D6056 (abutment) | Different category entirely |
Important: Do not use bridge codes for implant-supported provisionals. Implants have their own code set (D6000 series).
How to Explain Temporary Bridge Codes to Patients
Patients do not care about CDT codes. They care about cost, comfort, and clarity. Here is a script for dental front office staff.
“Mrs. Jones, your new permanent bridge will take about three weeks to arrive from the lab. During that time, we will place a temporary bridge to protect your teeth. The temporary itself is included in your bridge fee. However, because one of your teeth is very broken down, we need to add a post and core to hold the temporary securely. That part has its own code, D6972. Your insurance typically covers 50% of that. Would you like me to check your exact benefit?”
This approach is honest, clear, and patient-friendly.
Regional Differences in Temporary Bridge Coding
Dental codes are standardized across the United States (CDT codes). However, insurance plans in different states may interpret them differently.
- California: Many PPO plans require pre-authorization for D6970.
- Texas: Some Medicaid plans do not cover any post and core for temporary bridges.
- Florida: Delta Dental often bundles D6972 into the bridge fee unless a narrative is attached.
- New York: Most plans cover prefabricated posts but not indirect.
Always check your local plan guidelines.
The Future of Dental Coding for Temporary Bridges
The CDT code set is updated every year. There has been discussion about creating a specific code for a “provisional fixed partial denture” (temporary bridge). As of 2026, that code does not exist. But it may appear in future editions.
For now, D6970 and D6972 remain the closest official codes for temporary bridge support.
Quick Reference Card for Dental Teams
Print this section and keep it near your billing computer.
For a temporary bridge WITHOUT a post and core:
- Do not bill separately.
- Include in permanent bridge fee.
For a temporary bridge WITH a prefabricated post and core:
- Code: D6972
- Documentation needed: Pre-op X-ray, post-op X-ray, narrative.
For a temporary bridge WITH an indirect post and core:
- Code: D6970
- Documentation needed: Lab slip, impression record, pre and post X-rays.
Do NOT use:
- D5820 (that is a removable partial)
- D9999 (unspecified – last resort only)
- D6740 alone (that is the permanent crown only)

Frequently Asked Questions (FAQ)
1. Is there a specific dental code just for a temporary bridge?
No. As of 2026, there is no standalone CDT code for a temporary bridge. It is usually included in the permanent bridge fee.
2. When do I use D6970 for a temporary bridge?
You use D6970 when a temporary bridge requires a custom (indirectly fabricated) post and core to support it.
3. Can a patient request a temporary bridge without getting a permanent one?
No. A temporary bridge is only part of the process for a permanent bridge.
4. Will my insurance pay for a temporary bridge?
Insurance typically does not pay separately for a simple temporary bridge. However, if a post and core (D6972 or D6970) is needed, that part may be covered.
5. What is the difference between D6970 and D6972?
D6970 is for a custom lab-made post and core. D6972 is for a prefabricated (ready-made) post and core.
6. How long does a temporary bridge last?
Two to four weeks on average. With excellent care, some last two to three months.
7. Can I eat normally with a temporary bridge?
You should avoid sticky, hard, or crunchy foods on that side of your mouth. Stick to soft foods when possible.
8. What happens if my temporary bridge falls off?
Call your dentist immediately. Do not try to re-cement it with household glue. They will recement it properly.
9. Does Medicare cover temporary bridges?
Original Medicare does not cover routine dental work, including bridges. Some Medicare Advantage plans may offer limited coverage.
10. Can I bill D6970 and D6972 on the same tooth?
No. Only one post and core per tooth per bridge.
Conclusion
To summarize clearly: there is no single dental code for a temporary bridge. For simple cases, the temporary is included in the permanent bridge fee. For cases requiring extra support, you use D6970 (indirect post and core) or D6972 (prefabricated post and core). Always document thoroughly, verify insurance benefits in advance, and explain the process honestly to patients.
