Apicoectomy in Green Bay
— when a root canal alone isn’t enough to save the tooth
When infection persists at the tip of a root after root canal treatment — or when re-treating the root canal isn’t possible — an apicoectomy offers a surgical solution to save the tooth. The procedure removes the infected root tip and seals it from below, giving the tooth a second chance.

In-office root end surgery — specialized care to save your natural tooth

Treating infection at the root tip when root canal alone isn't enough

Standard root canals treat infections from inside the tooth's canal system by removing damaged pulp. However, because root structures possess microscopic, branching networks near the apex, bacteria can occasionally hide and persist at the very tip of the root. This is often caused by complex local anatomy, an undetected accessory canal, or a tiny micro-fracture near the apex.

An apicoectomy bypasses the upper tooth crown entirely, approaching the persistent infection surgically from beneath the gum line. By removing the actively infected tissue along with the last few millimeters of the root tip, we clear out the bacterial reservoir and apply a bioceramic seal from below to prevent re-infection.

Surgical Metrics Blueprint

Appointment Length: 30–90 minutes total chairside block

Comfort Options: Local anesthesia (conscious oral or IV sedation available)
Immediate Recovery: 2–3 days of mild post-operative soreness
Bone Regeneration: Full structural healing of the socket over 3–6 months
Clinical Success Rate: 85%–95% predictable success in appropriate cases
Restoration Impact: No crown replacement needed — crown remains untouched
Clinical Decision Matrix
Evaluating Your Tooth-Saving Options
“When a past root canal fails or an infection persists at the apex, you typically have three options. Here is how they compare — and when each makes the most clinical sense:”

Root canal re-treatment

Best when: The original root canal filling material can be easily accessed, canals were missed during initial therapy, or inadequate filling depth can be safely cleaned and replaced non-surgically.

Not ideal when: A permanent post or complex porcelain crown makes entering the tooth highly destructive, internal root anatomy is blocked, or infection is locked tightly at the root tip.

Apicoectomy (root-end surgery)

Best when: The existing root canal filling is dense and well-filled, an expensive post or crown cannot be safely disturbed, and the persistent infection is isolated exclusively at the root tip.

Key advantage: A precise microsurgical approach cleans and seals the root end from the outside, achieving a 85%–95% success rate to save your natural tooth.

Extraction & dental implant

Best when: The tooth structure is non-restorable, a vertical root fracture is present, or both non-surgical and surgical endodontic attempts have failed.

Not ideal as a first resort: Losing a natural tooth has permanent structural and financial consequences. We always exhaust tooth-saving options first.

The Microsurgical Sequence

Our Precise 4-Stage Protocol

01

Anesthesia

Local anesthesia is thoroughly administered to secure complete numbness. Conscious sedation options are available for highly anxious patients. You will feel pressure but no sharp pain.


02

Access & cleaning

A small incision is made in the gum tissue near the root apex. The persistent infection and inflamed tissue are thoroughly removed from around the root end under direct vision.


03

Root tip removal & seal

The final few millimeters of the root tip are removed. The root end is prepared and sealed with a advanced, biocompatible retro-filling material to permanently prevent re-infection from below.


04

Closure & healing

The gum tissue is gently sutured back into place. Over the next 3 to 6 months, natural bone structure heals completely over the sealed root tip. The tooth remains fully functional.


Microsurgical precision to give your tooth a second chance

In-office microsurgical care

We perform apicoectomies directly in our familiar, comfortable office environment — completely avoiding the extended wait lists, travel times, and high specialist costs of an external endodontic surgery clinic.

Advanced surgical magnification

Our team utilizes specialized high-power surgical loops and illuminated magnification tools during root end surgery. This allows for microscopic precision that is impossible without enhanced visualization.

Tooth-preservation philosophy

We believe your biological teeth are always worth fighting for. We recommend an apicoectomy only when clinical data confirms the tooth has an excellent long-term prognosis. If extraction is necessary, we tell you honestly.

Frequently Asked Apicoectomy Questions
Root canals clean infections from inside the main root channels. However, because root tips feature complex, microscopic branching networks, bacteria can occasionally persist in unreached accessory canals or an undetectable micro-crack at the apex. An apicoectomy approaches the problem surgically from outside the tooth, removing the infected tip directly.
 
Not at all. The procedure is performed under thorough local anesthesia, ensuring you experience zero sharp pain — only mild touch pressure. Post-operative soreness and minor localized swelling for 2 to 3 days is normal and easily managed with standard over-the-counter pain relievers. Most patients find it far more comfortable than expected.
 
For appropriately selected cases where the tooth's core structure is sound and the infection is isolated strictly to the root apex, apicoectomies boast an excellent, well-documented success rate of 85% to 95%. We only recommend the procedure if your tooth displays a strong long-term prognosis.
 
In the vast majority of cases, no. Because the surgical approach accesses the root end from beneath the gum line, your existing porcelain crown or filling remains completely undisturbed. This is one of the primary benefits of an apicoectomy over root canal re-treatment, saving you the time and expense of crown replacement.
