Apicoectomy & Endodontic Microsurgery
in Austin, TX
 An apicoectomy in Austin, TX is the surgical option for saving a tooth when a previous root canal hasn’t fully resolved an infection at the root tip. At Oral Surgery Specialists of Austin, we perform endodontic microsurgery (the technical name for the procedure) for patients referred by their general dentist or endodontist, as well as for patients who come to us directly with persistent pain or swelling around a previously treated tooth. The goal is to keep your natural tooth in your mouth instead of moving to extraction and replacement.
Most root canal treatments work the first time, and most root canals never need a second look. But in a small percentage of cases, an infection persists at the very tip of the root, where conventional retreatment through the crown can’t reliably reach. That’s where an apicoectomy comes in. Instead of going through the top of the tooth, we go in through the gum near the root tip, remove the infected tissue, seal the end of the root, and let the area heal.
We work alongside referring dentists and endodontists, not in place of them. Your restorative dentist still owns the long-term tooth restoration, and any post-op coordination with the endodontist is part of how we run these cases. Apicoectomy is one of several surgical procedures our team performs at our South Austin office, and we plan it the same way we plan any precision surgical case: from a CBCT scan that shows what 2D imaging can’t.

What Is an Apicoectomy?
 An apicoectomy, sometimes called endodontic microsurgery or root-end surgery, is a procedure that removes the tip of a tooth’s root along with any infected tissue surrounding it. We then seal the remaining root with a small filling at the end, called a retrograde filling, and close the gum over it. Bone heals around the area over the next several months, and the tooth, in most cases, stays in place and continues to function.
The procedure exists because the inside of a tooth’s root system is anatomically complex. A standard root canal treatment cleans and fills the main canal through the crown of the tooth, but small accessory canals or branches can sometimes harbor bacteria that the main canal cleaning doesn’t reach. When those bacteria persist, an infection can form at the very tip of the root, called a periapical infection. The infection shows up on a 2D X-ray as a dark area at the root tip, and on a CBCT scan as a more clearly defined defect in the surrounding bone.
When that happens, you have three options. First, your endodontist may attempt non-surgical retreatment, going back through the crown to clean the canal again. This works in many cases. Second, if retreatment isn’t viable, an apicoectomy approaches the same problem from a different angle, going through the gum to clean and seal the root tip directly. Third, if neither approach is appropriate, the tooth may need to come out, often followed by tooth extraction and a replacement plan.
When an Apicoectomy Is the Right Call
Apicoectomy is the right call in a few specific scenarios. You have a high-quality crown on the tooth and disturbing it for retreatment is not ideal. The original root canal had a complication (a separated instrument, a calcified canal) that makes retreatment unreliable. The root anatomy includes accessory canals that the main canal cleaning didn’t reach. CBCT imaging shows a defined periapical lesion that has not healed despite an otherwise successful root canal. Your endodontist or general dentist will usually identify the right approach and send you to us with a specific recommendation, but if you’re researching this on your own, we can review your records and tell you whether apicoectomy is appropriate.
Your Apicoectomy Surgeons in Austin
Apicoectomy is a microsurgical procedure that requires precision over speed: the surgeon is working at the root tip of a tooth, often a few millimeters from a nerve, sinus, or adjacent root. Both Oral Surgery Specialists of Austin surgeons are board-certified oral and maxillofacial surgeons whose residency training included this exact category of fine surgical work.
Dr. Derrick Flint completed his oral and maxillofacial surgery and anesthesia residency at the University of California, San Francisco, followed by a fellowship in cosmetic and cleft lip and palate surgery. He is a Diplomate of the American Board of Oral and Maxillofacial Surgery. His fellowship work in cleft lip and palate surgery required fine, anatomically precise tissue handling, the same precision apicoectomy demands. More on Dr. Flint’s bio.
Dr. Ricardo Garza earned his DMD from Harvard School of Dental Medicine and his MD in 2020, then completed his oral and maxillofacial surgery residency at UT Health San Antonio. He is fluent in both English and Spanish, which matters because referrals for apicoectomy often come with detailed clinical questions, and the patient should understand what is being recommended in their primary language. Background on Dr. Garza’s bio.
The Apicoectomy Process Step by Step
 An apicoectomy is typically a single-appointment procedure scheduled for sixty to ninety minutes from start to finish, with most of the actual surgical work taking thirty to forty-five minutes.
Step 1: CBCT Scan and Surgical Plan
We take a cone beam CT scan in our office before scheduling, either at a separate consultation or at the start of the surgical visit if the case is straightforward. The scan shows the exact root anatomy, the size and shape of any periapical lesion, the position of the maxillary sinus or inferior alveolar nerve relative to the root tip, and any anatomic features that change the surgical approach. We plan the access angle from the scan, not from the chair.
Step 2: Anesthesia and Comfort
We perform most apicoectomies under local anesthesia alone. For patients with more anxiety or for more complex cases (multiple roots, posterior teeth with limited access), IV sedation is available. With local alone, you stay awake and relaxed, but the area is fully numbed and you do not feel pain. If you are receiving IV sedation, you will need an empty stomach for eight hours beforehand and a responsible adult to drive you home.
Step 3: Surgical Access and Root-End Resection
We make a small access through the gum near the root tip, gently lift the tissue, and expose the underlying bone. Through a small bony window, we remove the infected tissue and resect the last few millimeters of the root tip, where most accessory canals and the highest concentration of bacteria are typically found. We send the resected piece for histopathologic analysis when the case warrants it, particularly when the imaging looked atypical and we want to rule out oral pathology beyond a routine periapical infection.
Step 4: Retrograde Filling and Closure
We seal the cut end of the root with a biocompatible filling material designed to bond well to dentin and resist bacterial recolonization, then close the gum with sutures. Most patients have absorbable sutures that dissolve on their own; a follow-up visit in seven to ten days confirms healing has started normally.
Step 5: Healing and Long-Term Outcome
Soft-tissue healing usually takes one to two weeks, with most patients returning to work the next day. Bone healing at the root tip takes longer (typically four to twelve months) and we follow up with a 2D X-ray or repeat CBCT to confirm the periapical lesion has resolved. The crown on the tooth, if it is in good shape, stays in place. The tooth itself continues to function as a normal tooth in most cases.
Benefits of Apicoectomy
The main benefit of an apicoectomy is that you keep your tooth. After the procedure, the tooth continues to function, the crown stays in place, and you avoid the cost and complexity of an extraction-and-replacement plan.
Your natural tooth has biomechanical and biological advantages a replacement can’t fully duplicate. The bone around a natural tooth root maintains itself; replacing it with an implant means we add bone and an artificial structure that has to integrate. Even an excellent dental implant requires several months of healing, and a final restoration that has to be planned, fabricated, and placed. Saving the tooth, when our CBCT and surgical plan say it can be saved, is the simpler long-term path.
If you already have a high-quality crown on the tooth, an apicoectomy lets you keep it. Conventional retreatment requires the endodontist to drill back through the crown, which sometimes means redoing the crown afterward. The surgical approach we use goes in from the gum side instead. Your restorative dentist isn’t pulled back into the case to remake the crown, and you save the cost of a second restoration.
Apicoectomy resolves the specific category of root-tip infections that conventional retreatment cannot reliably reach. CBCT imaging in our office tells us in advance whether your case fits that category, so we are not gambling: we know going in what is causing the persistent symptoms and what we need to do to fix it.
Compared with extraction-and-implant, an apicoectomy is a single visit at our in-office surgical suite with a short recovery. Most patients have soft-tissue healing within two weeks, no temporary appliance to wear, and no months-long wait for an implant to integrate before final restoration. For patients who can be candidates, this is the simpler path.
Why Choose Our Team for Apicoectomy
Apicoectomy is often referral work. The dentist or endodontist sending the patient wants to know that the surgeon receiving the referral has the microsurgical training to do the case well, and that the patient will be cared for the way a peer-referred patient should be.
Both surgeons are board-certified oral and maxillofacial surgeons with full residency training in fine, anatomically precise surgical work. Dr. Flint’s fellowship in cleft lip and palate surgery and Dr. Garza’s residency at UT Health San Antonio both included extensive microsurgical training. Apicoectomy is microsurgery in a small space.
We plan every apicoectomy from a CBCT scan we take in our office, not from a panoramic or referring 2D image. The scan defines the exact relationship between the root tip and the surrounding anatomy (sinus, inferior alveolar nerve, mental foramen, adjacent root) so we know what we are working around before the first incision.
We coordinate with the referring provider before and after the procedure. Your endodontist or general dentist receives the surgical plan in advance, the operative note after the procedure, and follow-up imaging when bone healing is confirmed. The goal is to solve the surgical problem and return you to the dentist who manages your overall care.
Most apicoectomies happen in our in-office surgical suite, which is what allows us to keep these cases as same-visit appointments rather than scheduling separate consults and surgical days. For complex cases with unusual anatomy or medical complications, our surgeons perform surgery at Seton, St. David’s, Dell Children’s Medical Center, and Dell/Seton University Medical Center if a hospital setting is the right call.
Apicoectomy Cost and Financing
Cost matters, and we want to be straight with you about how the cost of an apicoectomy is calculated. The cost depends on which tooth (front teeth are simpler than molars), how complex the root anatomy is on your CBCT, and your sedation preference (local alone vs IV). We will not quote you a price without first reviewing the scan, because the difference between a one-rooted front tooth and a multi-rooted molar is significant.
Insurance coverage for apicoectomies varies. Some dental plans cover the procedure as endodontic microsurgery; some classify it as oral surgery; some cover a portion either way. The strength of coverage often depends on whether the procedure is being done to save a tooth that has a documented prior root canal. We pre-verify your benefits and provide a written estimate before scheduling, including coordination with the original endodontist’s billing if needed.
For the portion not covered by insurance, oral surgery financing through outside lenders is available, including options for medical loans and dedicated dental financing. Compared with the long-term cost of a tooth extraction plus implant, an apicoectomy is usually the less expensive path when it is clinically appropriate.

Frequently Asked Questions
What is the difference between an apicoectomy and a root canal?
A root canal cleans and fills the inside of the tooth’s main canal through the crown. An apicoectomy goes in from the outside through the gum, removes the tip of the root, and seals the cut end. Both procedures address infection inside the tooth, but they approach it from opposite directions. A root canal is the first-line treatment, and an apicoectomy comes in when a previous root canal has not fully resolved the infection.
Will the apicoectomy hurt more than my original root canal?
Most patients say no. The original root canal involved drilling through your tooth, accessing the nerve chamber, and cleaning the canal repeatedly with files and irrigants. An apicoectomy is a focused surgical procedure done under local anesthesia (with IV sedation available if you would prefer), and the area is fully numbed throughout. Most patients describe the post-op as a mild to moderate ache that responds well to over-the-counter pain medication.
Why didn’t my dentist do an apicoectomy the first time instead of a root canal?
A root canal is the first-line treatment for an inflamed or infected tooth pulp because it is less invasive, has a high success rate, and preserves the most tooth structure. An apicoectomy is reserved for the small percentage of cases where the original root canal has not resolved the infection, often because of complex root anatomy or a complication during the original procedure. Doing apicoectomy first would be over-treating the typical case. We use 3D imaging to identify when retreatment alone will not work and surgery is the right next step.
Why an oral surgeon for this and not my endodontist?
Oral and maxillofacial surgeons train in microsurgical procedures involving bone, soft tissue, and nearby anatomic structures (nerves, sinuses, adjacent roots) for years during residency. The surgical access for apicoectomy goes through the gum and bone, one of the oral surgical procedures our team is trained for. Many endodontists also perform apicoectomies, especially when they have advanced microscope-based training. The right answer often depends on the complexity of the case and the referring provider’s preference. Either approach can produce excellent outcomes.
How successful is an apicoectomy?
Modern apicoectomy success rates, performed with CBCT planning and microsurgical technique, are reported in the dental literature at around 85% to 95% in the right candidate. Success means the periapical lesion resolves on follow-up imaging and the tooth functions normally without symptoms. Older surgical techniques without microsurgical principles had lower success rates, which is why this procedure has a reputation that does not match its current outcomes. We give you an honest estimate of expected success based on your specific scan.
How long is recovery after an apicoectomy?
Most patients return to normal activity the next day. Soft-tissue healing usually takes one to two weeks, and we use absorbable sutures that dissolve on their own. The bone heals at the root tip more slowly (four to twelve months on follow-up imaging), but you do not need to do anything special during that time. Avoid biting hard food on the surgical area for the first week and follow the post-op instructions we send home with you.
Will I need a new crown after the apicoectomy?
Usually no. The crown stays in place during the apicoectomy because the surgery does not go through the top of the tooth. If your crown was already failing or due for replacement, your restorative dentist may want to address it separately, but the apicoectomy itself does not require a new crown.
What happens if the apicoectomy doesn’t work?
If the apicoectomy does not fully resolve the infection (which is uncommon in the right candidate), the next step is usually tooth extraction followed by replacement with an implant, bridge, or partial denture. We will know within a few months on follow-up imaging whether the procedure has succeeded. Going in, we also tell you honestly whether your specific case has a higher-than-average chance of needing extraction eventually, so you can factor that into your decision. |
