Apicoectomy Waterloo
The teeth are held firmly in place by strong roots that extend into the jawbone. Molars and premolars tend to have several roots, whereas the front incisors only have a single root. The end or tip of each root is termed the apex. The apex is where the nerves and blood vessels enter the tooth, and aids in the delivery of blood to the crown (the part of the tooth you can see in your mouth).
A root canal treatment refers to the cleaning of the canals and the removal of infected and inflamed tissue within the root. When the inflammation or infection persists after the root canal treatment, an apicoectomy may be required. An apicoectomy is essentially the removal of the apex (or root tip), followed by a filling procedure to seal the root from further infection. When left untreated, infected roots can damage other teeth, spread infection, and cause regression of the jawbone.
Reasons for an Apicoectomy
Infected and inflamed soft tissue around the root of a tooth can be exceptionally painful and debilitating to the patient. The purpose of an apicoectomy is to eliminate the infection in the tissue and to ultimately preserve the function of the tooth and save it from extraction. An apicoectomy will rarely be considered by the dentist unless a prior root canal treatment has failed.
There are several reasons why an apicoectomy may be necessary:
- Small Adjoining Root Branches – Roots are extremely complex and can contain many tiny branches. If these tiny branches cannot be cleaned and sealed when the root canal treatment is performed, inflammation can persist.
- Blocked Root Canal – In some cases, the dentist is unable to effectively clean a root canal because it is blocked by a fractured file left behind from prior root canal treatment. Infection and debris can quickly affect adjacent teeth.
- Narrow or Curved Root Canals – When the root canal is poorly shaped, the endodontic files cannot reach the root tip. Continuing infection or re-infection can then occur.

What Does Getting an Apicoectomy Involve?
Prior to the surgery, the dentist will generally prescribe an antibiotic or anti-inflammatory medication to treat the underlying infection. Panoramic x-rays will then be taken to enable the dentist to plan the apicoectomy, which will be performed under local anesthesia.
The dentist will make a small incision in the gum and expose the root by lifting away the gum. In some cases, a tiny fraction of the jawbone may be removed to properly expose the root. The edge of the root tip and any infected connective tissue will be removed using ultrasonic instruments. The root will be sealed using a retrofill (filling material) and the dentist will suture the gum with several stitches.
This surgery does not require an overnight stay, and full aftercare instructions and pain medications will be provided as needed. After several days, the dentist in Waterloo will remove the stitches, and the connective tissues will fully heal several months after the procedure.

What to Expect From an Apicoectomy
An apicoectomy is a small surgical procedure that removes the tip of a tooth root (the apex) along with any infected tissue around it. It is typically considered when a previously root-canal-treated tooth develops or retains an infection at the root tip that cannot be resolved by redoing the root canal through the crown. The procedure takes 30 to 90 minutes per tooth and is done under local anaesthetic, often with sedation available.
On the day of surgery, the area is numbed and a small incision is made in the gum near the affected tooth root. A small portion of the bone covering the root tip is removed, the infected tissue is cleared, and the very end of the root (a few millimetres) is removed. The cleaned root canal opening is then sealed with a biocompatible material to prevent reinfection. The gum is repositioned and closed with a few fine sutures. The procedure is generally well tolerated, and most patients drive themselves home afterward unless sedation was used.
Healing happens over weeks to months. Bone gradually fills in around the treated root tip; a follow-up x-ray at six months and again at a year confirms the bone has rebuilt. Most patients keep the tooth long-term with this procedure; success rates for apicoectomy when performed for the right indications are reported in the 80 to 95 percent range, depending on the case.
When an Apicoectomy Is Considered
An apicoectomy is not the first option for a tooth with infection — root canal retreatment through the crown is usually tried first. An apicoectomy comes into play when:
- A root-canal-treated tooth has persistent or recurrent infection at the root tip despite re-treatment
- The root canal cannot be re-accessed through the crown because of a post, large restoration, or curved root anatomy
- Calcified canals make conventional re-treatment impossible
- A small cyst or granuloma needs to be removed surgically along with the root tip
- A root fracture is suspected and needs direct surgical inspection
- Saving the natural tooth is preferred over extraction and replacement with an implant or bridge
If the tooth has structural damage too extensive to support, or if other options (extraction, implant) better serve the long-term plan, those alternatives are discussed at the consultation.
Recovery and Healing After Apicoectomy
Mild swelling and discomfort for two to three days is normal after the procedure. Ice packs on the cheek for the first 24 hours help reduce swelling. Over-the-counter pain medication usually handles the discomfort; stronger prescriptions are available if needed. Avoid brushing directly over the surgical site for the first few days; rinse gently with the prescribed antimicrobial rinse instead. Sutures are usually removed at the one-week follow-up.
Diet for the first few days is soft and on the opposite side of the mouth. Avoid hot, spicy, hard, or sticky foods that could disturb the surgical site. Smoking should be avoided for at least one week — it significantly reduces healing. Most patients are back to normal activities within a few days; strenuous exercise waits until the surgeon clears it.
Follow-up visits are at one week, three months, six months, and one year. The x-rays at these visits show bone healing around the treated root tip. If healing is on track, the tooth functions normally and follow-up moves to your regular cleaning schedule.
Cost and Insurance Coverage
Apicoectomy cost depends on which tooth is treated and the complexity of the surgery. Front teeth are simpler and lower-cost than back teeth, which have more complex root anatomy. Trillium follows the current Ontario Dental Association Suggested Fee Guide for surgical endodontic procedures, and we provide a written estimate before treatment.
Most private dental insurance plans cover a portion of apicoectomy under endodontic or surgical services. Coverage levels vary; we submit a pre-determination to your insurer before treatment so your share is clear in advance. Direct billing is available with plans that allow it.
Frequently Asked Questions
Why not just pull the tooth and place an implant?
Saving a natural tooth is usually preferable when realistic. Natural teeth have ligament attachments that implants do not, and an implant involves removing the tooth, healing, possible bone grafting, and several months of treatment. An apicoectomy can preserve the natural tooth in one surgery when conditions are right.
Does an apicoectomy hurt?
The procedure itself is done under local anaesthetic, so there is no pain during surgery. Post-operative discomfort is usually mild to moderate for two to three days, managed with over-the-counter medication. Most patients report less discomfort than they expected.
How long does the tooth last after the procedure?
Many teeth keep functioning for ten, twenty, or more years after a successful apicoectomy. Success rates are 80 to 95 percent at follow-up, depending on the case. Regular cleaning visits and good home care extend the result.
Will I have a scar on my gum?
The incision is small and inside the mouth at the gum line. Healing usually leaves no visible scar after a few weeks. Some patients notice a faint line in the gum that fades over time.
How long until I can eat normally?
Soft foods on the opposite side for three to four days, gradually returning to a normal diet over the next week. Avoid chewing directly on the treated tooth until the dentist confirms healing is well underway, usually around the two-week mark.
What if the apicoectomy does not work?
If healing does not progress as expected, options include further endodontic treatment or extraction of the tooth. This outcome is uncommon when the procedure is appropriately indicated, but it is part of the conversation at consultation so expectations are realistic.
