D3472

Surgical repair of root resorption — premolar

Code Summary

D3472 is the CDT code for the surgical repair of root resorption on a premolar (bicuspid) tooth — surgery to access and repair a defect where the tooth's root structure is being broken down (resorbed) by the body, to stop the process and save the tooth. It's the premolar version, with separate codes for anterior (D3471) and molar (D3473) teeth.

What D3472 means

D3472 covers the surgical repair of root resorption — premolar. "D" is dental, "34" is the endodontic surgery group, and "72" is this premolar root resorption repair. Like the anterior version (D3471), it's surgery to address root resorption — a process where the body's cells break down and remove the tooth's root structure, which can weaken and eventually destroy the tooth if it progresses. The surgery accesses the resorption defect, removes the resorbing tissue, and repairs the defect (filling or sealing it with an appropriate material) to halt the resorption and preserve the tooth. This code is for that surgical repair on a premolar (bicuspid) — the teeth between the canines and the molars.

The procedure is coded by tooth type: anterior (D3471), premolar (D3472, this one), and molar (D3473), reflecting the different access and complexity for different teeth.

Premolars, being further back than front teeth and sometimes having two roots, can be a bit more complex to access for this surgery than anterior teeth, but the procedure is the same in principle — halting the resorption by removing the resorbing tissue and repairing the defect. Success depends on the type, location, and extent of the resorption. Coverage is under endodontic/surgical benefits, with documentation (imaging showing the resorption). It's used for accessible, repairable resorption defects on premolars.

When it's typically used

D3472 is reported for the surgical repair of root resorption on a premolar (bicuspid) tooth — accessing and repairing a defect where the tooth's root structure is being broken down by the body, to stop the resorption and save the tooth, when the defect can be surgically accessed and repaired.

How much does D3472 cost?

Surgical repair of root resorption on a premolar is a moderate-to-significant fee, often roughly 650 to 1,250 USD depending on region — for the surgical procedure, often a bit more than the anterior version (reflecting the premolar's location and possible anatomy). Associated procedures (root canal treatment, grafts) may be separate. It's an investment to try to save a tooth affected by resorption.

Is D3472 covered by insurance?

Covered under endodontic/oral surgery benefits, often around 50-80 percent, with documentation (imaging, often 3D/cone-beam CT, showing the resorption defect and its extent) justifying the surgical repair. It's coded by tooth type (premolar here). Pre-authorization is often advisable. The prognosis and the resorption's nature should be documented. Associated procedures may be separate.

Root resorption on premolars

Root resorption can affect premolars, and understanding this clarifies the surgical repair on these teeth.

Root resorption — the body's cells breaking down the tooth's root structure — can affect any tooth, including premolars. The causes are the same as for other teeth: trauma (an injury initiating resorption), inflammation or infection, pressure (such as from an adjacent impacted tooth, which can be relevant for premolars near impacted canines or other teeth), certain conditions, or sometimes no clear cause. When resorption affects a premolar and creates a defect that can be surgically accessed and repaired, the surgical repair (D3472) can be done to halt the process and save the tooth. The premolar's location (further back than front teeth) and its anatomy (one or two roots, depending on the tooth) are factors in accessing and performing the surgery.

Like resorption on other teeth, premolar resorption can progress and threaten the tooth if unchecked, so addressing it (when feasible) is important to try to preserve the tooth. The surgical repair removes the resorbing tissue and repairs the defect, aiming to stop the resorption. The approach is tailored to the premolar's anatomy and the resorption's location. For patients, understanding that root resorption can affect premolars — from the same causes as other teeth — and that surgical repair can address it on premolars clarifies this procedure on these teeth. The surgery aims to halt the resorption and save the premolar, accounting for the tooth's location and anatomy. The dentist or specialist diagnoses the resorption (often with detailed imaging) and determines whether surgical repair is feasible for the premolar. Understanding resorption on premolars helps patients see why the surgical repair is done — to stop the destructive process and preserve the premolar affected by resorption, when the defect can be accessed and repaired on this tooth.

Access considerations for premolar surgery

Surgery on premolars has particular access considerations, and understanding them clarifies the premolar root resorption repair.

Premolars (bicuspids) are located between the canines and the molars, further back in the mouth than the front teeth. This location makes surgical access somewhat more involved than for anterior teeth (which are at the front and very accessible), though still more accessible than molars (at the very back). Additionally, premolars can have one or two roots depending on the specific tooth (upper first premolars often have two roots, for example), and the root anatomy affects the surgery — the surgeon must access and address the affected root (and its resorption defect), accounting for the root configuration. The proximity of premolars to certain structures (such as the sinus for upper premolars, in some cases) may also be a consideration. So the premolar's location, root anatomy, and surroundings are factors in planning and performing the surgical repair of resorption on a premolar.

These access considerations are part of why the surgical repair of resorption is coded by tooth type — the premolar code (D3472) reflects the premolar's particular access and complexity, between the more accessible anterior teeth and the more complex molars. The surgeon plans the access (often with imaging to assess the root anatomy and the resorption defect) to perform the surgery effectively on the premolar. For patients, understanding the access considerations for premolar surgery — the location, root anatomy, and surroundings — clarifies why the premolar root resorption repair has its own code and what's involved in accessing the premolar for the surgery. The premolar is a bit more involved than a front tooth but more accessible than a molar. The dentist or specialist plans the surgery appropriately for the premolar's anatomy and location. Understanding the access considerations helps patients appreciate the planning involved in the premolar root resorption repair, ensuring the surgery can effectively access and address the resorption defect on the premolar to halt the process and preserve the tooth, accounting for the specific access challenges of the premolar's position and anatomy.

How the resorption repair is performed

Understanding how the surgical repair of root resorption is performed clarifies the procedure on a premolar.

The surgical repair aims to access the resorption defect, remove the resorbing tissue, and repair the defect to halt the process — the same principle as for other teeth, performed on the premolar. The procedure is typically done under local anesthesia. The surgeon accesses the resorption defect — for external resorption on the root surface, this usually involves making a gum incision and reflecting the tissue to expose the affected area of the premolar's root (accounting for the premolar's location and root anatomy). The surgeon then removes the resorbing (granulation) tissue that's causing the breakdown, cleaning out the defect. The defect in the root is then repaired — filled or sealed with an appropriate restorative material (such as a biocompatible material) to restore the root structure at that point and seal off the area, stopping the resorption from continuing there. The gum is then repositioned and closed, and it heals over the following weeks. Depending on the case, the premolar may also need root canal treatment (if the resorption involves or threatens the pulp).

So the surgery removes the cause of the resorption (the resorbing tissue) and repairs the resulting defect on the premolar, aiming to halt the destructive process and preserve the tooth. The access and repair are tailored to the premolar's location, root anatomy, and the resorption defect. The success depends on adequately removing the resorbing tissue and repairing the defect, and on the type and extent of the resorption. For patients, understanding how the surgical repair is performed on a premolar — accessing the defect, removing the resorbing tissue, and repairing the defect to halt the process — clarifies what the procedure involves. It directly addresses the resorption on the premolar by removing its active tissue and repairing the damage, to stop the breakdown and save the tooth. The surgeon performs the access and repair appropriate to the premolar. Understanding the procedure helps patients see how the surgical repair aims to halt the resorption and preserve the premolar, by removing the destructive tissue and restoring the root defect, giving the premolar a chance to be saved from the resorptive process.

Prognosis for saving a premolar with resorption

The prognosis of surgically repairing root resorption on a premolar varies, and understanding it helps set realistic expectations for saving the tooth.

The outcome of surgically repairing root resorption on a premolar — whether it successfully halts the resorption and saves the tooth — depends on several factors, as with resorption on other teeth. The type of resorption: some types are more amenable to treatment than others (certain accessible, localized external resorption defects may be repairable, while aggressive or invasive resorption is harder to halt). The location and extent: a defect that's accessible and hasn't destroyed too much of the root has a better prognosis, while extensive resorption that has significantly weakened the root is harder to save. How early it's caught: catching and treating the resorption earlier generally gives a better prognosis than treating advanced resorption. The premolar's anatomy and access: the ability to adequately access and repair the defect, which can be affected by the premolar's location and root anatomy. The success of the repair: adequately removing the resorbing tissue and repairing the defect.

So the prognosis for a premolar ranges from good (for accessible, localized, early-caught resorption successfully repaired) to guarded or poor (for extensive, advanced, or aggressive resorption, or hard-to-access defects). When the prognosis is reasonable, the surgical repair offers a chance to halt the resorption and save the premolar, which is worthwhile (premolars being functionally important). When resorption is too advanced, the tooth may not be salvageable. The surgeon assesses the prognosis (using detailed imaging) and discusses the realistic prospects with the patient. For patients, understanding that the prognosis varies — depending on the type, location, extent, timing, and access — helps set realistic expectations for the premolar resorption repair. It offers a chance to save the premolar when the resorption is treatable, but success isn't guaranteed, especially for advanced resorption. The surgeon provides realistic guidance based on the specific resorption, helping the patient decide whether the repair is worthwhile and understand the likelihood of saving the premolar. When feasible, the surgical repair is a valuable attempt to save a premolar that resorption would otherwise destroy.

Frequently asked questions

What is the D3472 dental code?
It's the surgical repair of root resorption on a premolar (bicuspid) tooth — surgery to access and repair a defect where the tooth's root structure is being broken down (resorbed) by the body, to stop the process and save the tooth. Anterior teeth use D3471 and molars D3473.
What is root resorption?
A process where the body's cells break down and remove the tooth's root structure — the root being eaten away. It can result from trauma, inflammation, pressure, certain conditions, or sometimes no clear cause, and if unchecked can weaken and destroy the tooth.
How is premolar surgery different from anterior?
Premolars are further back than front teeth (somewhat more involved access) and can have one or two roots, but more accessible than molars. The procedure is the same in principle — halting the resorption by removing the resorbing tissue and repairing the defect — accounting for the premolar's anatomy.
How is the repair performed?
Under local anesthesia, the surgeon accesses the resorption defect (often via a gum incision), removes the resorbing tissue causing the breakdown, and repairs the defect with a restorative material to halt the process. The premolar may also need root canal treatment.
How much does the premolar repair cost?
Often around 650 to 1,250 USD for the surgery, often a bit more than the anterior version (reflecting the premolar's location and anatomy). Associated procedures (root canal, grafts) may be separate.
Will the repair save the premolar?
It offers a chance, depending on the type, location, extent, and how early the resorption is caught, plus the access. Accessible, localized, early-caught resorption has a better prognosis; extensive or aggressive resorption is harder to halt. The surgeon assesses the prospects.
