Apicoectomy & Endodontic Microsurgery
in Federal Way, WA
 If you’re researching apicoectomy or endodontic microsurgery in Federal Way, WA, 253 Dental Care performs this surgical procedure when a previously root-canal-treated tooth develops persistent infection at the root tip and conventional retreatment is not the right path.
An apicoectomy is a precise surgical procedure performed at the very tip of a tooth’s root, the apex. We make a small incision in the gum near the affected tooth, expose the bone over the root tip, remove the infected tissue and the apical few millimeters of the root, and seal the end of the remaining root with a biocompatible material. The crown of the tooth and the existing root canal filling stay in place. The procedure saves the natural tooth in cases where extraction would otherwise be the only option.
Apicoectomy is one of the restorative dentistry treatments we offer at our Federal Way office. It is the second-line option for a tooth where the original root canal was completed but symptoms of infection have returned and conventional retreatment through the crown is not feasible. Patients typically arrive for an apicoectomy consultation after a follow-up X-ray showed lingering infection at the root tip months or years after the original root canal, or after returning symptoms (lingering tenderness, pressure, or a small bump on the gum near the root tip) prompted us to investigate.

What Is an Apicoectomy?
An apicoectomy is the surgical removal of the very tip of a tooth’s root, along with any infected or inflamed tissue surrounding it, followed by sealing the end of the remaining root with a biocompatible filling material. The procedure is also called endodontic microsurgery, root-end surgery, or root-end resection. It saves a tooth that has persistent infection at the root tip when conventional retreatment through the existing crown is not the right answer.
When You Need an Apicoectomy
Most apicoectomies happen for one of these reasons: a previously root-canal-treated tooth developed a recurrent infection at the apex that did not resolve with antibiotics or initial retreatment; a structural issue (complex root canal anatomy, a previous post in the canal, or a fracture not detected on the original X-ray) makes conventional retreatment through the crown difficult or impossible; or the infection is confined to the root tip area and surgical access is more efficient than working back down through the existing restoration. The CBCT scan we take at the consultation tells us which of these is the situation.
Apicoectomy vs. Conventional Root Canal Retreatment
 A conventional root canal retreatment goes back into the tooth through the crown, removes the previous filling material from inside the canal, cleans the canal again, and refills it. Apicoectomy approaches the same problem from the opposite direction: instead of going through the crown, we go through the gum and bone to access just the apex. The choice between the two depends on the cause of the persistent infection. If we can successfully re-clean the canal, retreatment is usually the better choice because it is less invasive. If something at the apex prevents that – root anatomy, a fracture, a separated instrument, or a post that cannot be safely removed – apicoectomy is the appropriate next step.
Apicoectomy vs. Tooth Extraction
The other alternative is extracting the tooth and replacing it with a single tooth dental implant or a dental bridge, or accepting the gap. Extraction is a definite endpoint, but it removes a structurally intact tooth that already has a functioning crown on it, and it sets up a months-long timeline for implant integration before we can place a replacement crown. Apicoectomy preserves the tooth in place. The decision between apicoectomy and extraction usually comes down to whether the tooth, the crown, and the supporting bone are still in good shape; when they are, saving the tooth with apicoectomy is typically the more conservative option.
Your Apicoectomy Doctor in Federal Way
Dr. Mark Walker performs apicoectomy at our office. He graduated from the University of Washington School of Dentistry in 1981 and has handled the surgical procedures we perform in-house, including wisdom tooth removal, bone grafting, implant placement, and apicoectomy, throughout his career. He is a member of the Academy of General Dentistry, the International College of Dentists, the American College of Dentists, and the Pierre Fauchard Academy, and he served as past president of the Washington State Dental Association.
Apicoectomy is a precise procedure that we perform in a small surgical field at the root tip, often working millimeters from anatomically sensitive structures: the maxillary sinus for upper teeth, the mental nerve for lower premolars, and the nerves of adjacent teeth in any case. Dr. Walker plans every apicoectomy from a CBCT scan that shows the root tip’s three-dimensional position relative to those structures. The 3D plan makes the surgical access predictable and the procedure safer than working from a flat 2D X-ray alone.
The same office that handles the apicoectomy also handles the post-procedure follow-up and any subsequent restorative work the tooth may need, like a new crown if the existing one needs replacement. We do not ask patients to navigate between separate offices for the surgery, the imaging, the follow-up, and the related restorative work.
The Apicoectomy Process at Our Office
Most apicoectomy cases at our Federal Way office move through four stages: diagnostic imaging and consultation, pre-procedure preparation, the surgical procedure itself, and follow-up healing. The full timeline typically runs across two to three appointments, with the surgery itself taking about 60 to 90 minutes for a single tooth.
Diagnosis and 3D Imaging
We start with an exam and a CBCT (cone beam CT) scan of the affected tooth. The CBCT shows us the exact location of the apex relative to the surrounding bone, sinuses, and nerves, which is essential for planning the surgical approach. The scan also confirms whether apicoectomy is the right procedure or whether conventional retreatment through the crown might still resolve the infection.
Pre-Procedure Preparation
If the CBCT supports apicoectomy, we discuss the procedure, the recovery expectations, and the comfort options including oral conscious sedation for patients who would prefer it. We provide written pre-procedure instructions, and you continue your routine medications unless we identify a specific reason to adjust them. The procedure happens in our office under local anesthesia, with sedation available as an additional comfort layer if you choose it.
The Surgical Procedure
The surgery itself takes about 60 to 90 minutes for a single tooth. Dr. Walker numbs the area with local anesthesia, makes a small incision in the gum near the affected tooth, gently lifts the gum tissue to expose the bone, removes a small amount of bone over the root tip, and accesses the apex. Once the apex is visible, we remove the few millimeters of root that contain the persistent infection along with the surrounding inflamed tissue, then seal the cut end of the remaining root with a biocompatible material. We close the gum with sutures that typically dissolve over seven to ten days. Many patients are surprised by how routine the procedure feels, because the anesthesia is fully effective for the surgical site itself.
Healing and Follow-Up
Most patients return to routine activity within a day or two of the surgery. Some swelling and tenderness around the surgical site is normal for three to five days, and we manage discomfort with over-the-counter pain medication for most cases, with prescription options available if you need them. We see you back at one or two follow-up visits over the following weeks to confirm soft tissue healing. The bone underneath continues to heal over six to twelve months, and we typically take a follow-up X-ray at that mark to confirm the bone has filled in around the surgical site. We provide written aftercare guidance through our instructions library, including a dedicated apicoectomy recovery sheet.
Benefits of Apicoectomy
The most significant benefit of apicoectomy is that it preserves your natural tooth. The crown stays where it is, the chewing surface stays balanced, the adjacent teeth stay where they are, and the bone at the site stays intact. At our Federal Way office, this matters because the procedure addresses the persistent infection at the source – the apex – without removing the tooth, replacing it, or adding the months of healing that an extraction-and-implant pathway requires.

The CBCT scan and consultation at our Federal Way office tell us whether apicoectomy is the right move for your specific tooth or whether a different path makes more sense.
Why Choose 253 Dental Care for Apicoectomy
Many general practices refer apicoectomy cases to outside endodontic specialists. We perform the procedure in our Federal Way office because Dr. Walker has the surgical experience and the imaging tools to handle apicoectomy in-house: the CBCT scan for 3D planning, the soft tissue laser for gum access, and a records system that ties the apicoectomy to the original root canal records and any prior imaging from the same office.
For apicoectomy specifically, having the diagnosis, the CBCT, the surgery, the follow-up healing, and any subsequent restorative work all happen at the same office matters because of how the timeline plays out. The bone takes six to twelve months to heal under the surgical site. The follow-up X-rays during that period are most useful when we compare them against the pre-procedure imaging from the same office, on the same equipment, with the same chart documenting what was done. We do not ask patients to coordinate records between offices for those follow-up comparisons.
For cases where the apex is genuinely unreachable through standard surgical access – molars with complex anatomy, teeth too close to a major nerve, or anatomical situations where a surgical microscope is essential – we refer to an endodontist. The same honest framing that applies to our sedation conversation applies here: when an apicoectomy at our office isn’t the right answer for your specific case, we tell you, and we point you to the provider who is.
Apicoectomy Cost and Financing
The cost of an apicoectomy depends on the tooth being treated (single-rooted teeth like front teeth are simpler than multi-rooted molars), the complexity of the surgical access, whether sedation is added, and whether bone grafting is needed at the same appointment to fill the surgical defect after we remove the infected tissue. We provide a written estimate at the consultation, after the CBCT scan has shown us exactly what the procedure will involve.
Insurance coverage for apicoectomy varies. Most plans cover apicoectomy when it is medically necessary to save a tooth that already has a documented root canal, since the procedure is more conservative than extraction and replacement. Coverage often runs at the same percentage as oral surgery rather than as a routine procedure. Our front office team verifies your specific apicoectomy benefits before treatment, including whether the original root canal records on file affect coverage and whether the plan requires pre-authorization.
For amounts not covered by insurance, we work with third-party financing partners including CareCredit, Lending Club, and United Medical Credit. Patients without dental insurance can also enroll in our annual loyalty program. The cost of an apicoectomy is typically lower than the combined cost of extraction, bone preparation, implant placement, and a new crown, which is part of why apicoectomy is often the more economical choice when the tooth qualifies for it.

Frequently Asked Questions
How is an apicoectomy different from a root canal?
We perform a traditional root canal entirely through the crown of the tooth: we drill a small access hole through the top, clean and shape the canals from inside, and seal them. From a patient’s chair-time perspective, it is a non-surgical procedure: there is no incision in the gum, no sutures, and the recovery is minimal. An apicoectomy is a small surgical procedure: we make an incision in the gum, work at the root tip from the outside, and place sutures at the end. The recovery involves mild swelling and tenderness for a few days. The two procedures address different problems: a root canal treats the inside of an untreated tooth, while an apicoectomy addresses persistent infection at the root tip after a root canal has already been done.
Will it hurt?
During the procedure itself, no. We fully numb the area with local anesthesia, and most patients describe what they feel as pressure rather than pain. After the procedure, the surgical site is typically tender for three to five days, with mild swelling that peaks around day two and improves from there. Most patients manage with over-the-counter pain medication; the recovery is generally easier than people expect, often comparable to a routine tooth extraction. Patients who chose oral conscious sedation for the procedure tend to remember less of the appointment itself.
How long is the recovery?
There are two distinct recovery timelines. The soft-tissue recovery (the gum closing back over the surgical site) takes about seven to ten days, with sutures dissolving on their own in that window. Most patients are back to routine activity within a day or two of the surgery and back to normal eating within a week. The deeper recovery (the bone filling in around where the apex used to be) takes six to twelve months. We confirm bone healing with a follow-up X-ray at that mark; in the interim, the tooth is fully functional even though the bone is still healing underneath.
What is the success rate?
For appropriately selected cases, modern apicoectomy success rates are above 90%, with some published series reporting 94 to 96% success when we use CBCT-based planning and current surgical techniques. Success in this context means the tooth remains symptom-free with bone healing visible on follow-up imaging at six to twelve months. The cases that do not succeed usually fall into one of three categories: an undetected vertical root fracture that the procedure did not address, a structural issue with the existing crown or root canal filling that is continuing to seed infection, or aggressive bacterial colonization that surgery alone cannot resolve. If an apicoectomy fails, the next step is usually extraction, since at that point the tooth has had every reasonable conservative option.
Should I just have the tooth pulled and get an implant instead?
It is a reasonable question, and for some teeth the answer is yes – extraction with implant placement is the right move when the tooth, the crown, or the supporting bone is compromised. But when the tooth and crown are still in good shape, apicoectomy is usually the more conservative option. Practically, an apicoectomy is one surgical appointment of 60 to 90 minutes followed by a recovery period; an extraction-and-implant pathway is typically two to three procedures (extraction, possibly bone grafting, implant placement, abutment, and final crown) spread across four to seven months and involving a more significant total cost. The tooth replacement looks and functions well, but it is not your tooth. The CBCT and exam are what tell us which path is the better fit for the specific tooth in question.
Why are you doing this instead of an endodontist?
Endodontists perform most apicoectomies in dentistry, since they are the specialists who focus on root canals and root-canal-related surgery. Some apicoectomy cases are appropriate for a general dentist with surgical experience to perform, typically straightforward cases on single-rooted teeth or premolars where the apex is accessible and the surgical anatomy is predictable on CBCT. Dr. Walker handles those cases at our office. For more complex apicoectomies (molars with complex anatomy, teeth in unusual positions, or cases where surgical microscopy is essential to the technique) we refer to an endodontist. The CBCT and consultation at our office tell us which side of that line your specific case is on, and we are upfront about it either way.
Will I need a new crown after?
Usually no. The apicoectomy works on the apex of the tooth, several millimeters below the gum line, and leaves the crown of the tooth completely undisturbed. The existing crown stays in place. The exception is if the crown was already failing for an unrelated reason, or if we need to redo the original root canal filling after the apicoectomy is complete (uncommon but possible). In those situations we would address the crown or restoration as a separate step after the apicoectomy has healed. Most patients leave the apicoectomy with the same crown they came in with, just with the underlying root tip now infection-free.
Does insurance cover apicoectomy?
Coverage details vary across insurance plans, so we recommend asking your insurance company three questions before your apicoectomy consultation: (1) Does my plan cover apicoectomy under codes D3410 (anterior tooth), D3421 (bicuspid/premolar), or D3425 (molar)? (2) Is apicoectomy covered at the same percentage as a root canal, or at the oral surgery percentage? (3) Is there a documentation requirement (the original root canal records, a radiograph showing persistent infection) for coverage? Our front office handles all of that for you when you give us your insurance details ahead of the appointment, but knowing the questions yourself is useful if you want to call your plan directly. For amounts not covered, our financing options include third-party partners and an in-office loyalty program.
