SURGICAL ENDODONTIC TREATMENT

Endodontic Surgery

Endodontic surgery, sometimes called surgical endodontic treatment, may be considered when a problem affecting the root of a tooth cannot be adequately managed through conventional root canal treatment or root canal retreatment.

One of the most common forms of endodontic surgery is an apicoectomy, also known as root-end surgery or root-end resection. The procedure provides direct access to the area around the end of a tooth root so that the endodontist can assess and treat the affected tissues.

At JCV Endodontics in Leederville, Perth, the decision to consider surgery is based on the individual tooth, your symptoms, previous treatment, clinical findings and diagnostic imaging. Surgery is not appropriate for every tooth, and reasonable alternatives are discussed before treatment is undertaken.

What is endodontic surgery?

Most root canal treatment is performed through an opening made in the crown of the tooth. This allows the endodontist to clean, disinfect and seal the root canal system from inside the tooth.

Endodontic surgery approaches the root from a different direction.

A small opening is made through the gum near the affected tooth so the endodontist can access the tissues and bone surrounding the end of the root. Depending on the diagnosis, treatment may involve removing inflamed or infected tissue, removing a small portion of the root tip and sealing the end of the root canal.

The exact procedure varies according to the tooth and the reason surgery is being considered.

What is an apicoectomy?

An apicoectomy is a type of endodontic surgery involving the tip, or apex, of a tooth root.

During the procedure, the gum is carefully moved to provide access to the area around the root. A small amount of tissue and, where necessary, bone may be removed to reach the affected area.

Inflamed or infected tissue around the root end can then be removed. A small portion of the root tip is generally removed and the end of the root canal may be prepared and sealed with a root-end filling.

The gum is repositioned and sutures are placed to support healing.

Why might endodontic surgery be considered?

Endodontic surgery may be considered in selected circumstances, including when:

  • inflammation or infection persists around the end of a previously root canal-treated tooth
  • part of the root canal system cannot be accessed effectively through the tooth
  • previous dental treatment or restoration makes conventional access difficult
  • calcification or complex anatomy limits access to part of a root canal
  • direct examination of the root may assist with diagnosis
  • there is a problem affecting the root surface or tissues surrounding the root.

The presence of pain or an abnormality on an X-ray does not automatically mean surgery is required. Assessment is needed to determine the likely cause and the reasonable treatment options for the individual tooth.

Endodontic surgery or root canal retreatment?

A previously root canal-treated tooth that develops symptoms does not necessarily require surgery.

In some cases, non-surgical root canal retreatment may allow the existing root canal filling to be removed so the canal system can be reassessed, cleaned and treated again.

In other circumstances, accessing the problem through the tooth may be difficult, undesirable or unlikely to address the area of concern. Surgical treatment may then be one option considered.

Factors that can influence the decision include:

  • the location and cause of the problem
  • the anatomy of the root canal system
  • previous root canal treatment
  • crowns, posts or other restorations
  • cracks or fractures
  • the amount of remaining tooth structure
  • periodontal and bone support
  • the position of nearby anatomical structures
  • whether the tooth can be predictably restored afterwards.

Your endodontist can explain why retreatment, surgical treatment, monitoring, extraction or another approach may or may not be appropriate for your particular tooth.

What happens before endodontic surgery?

Before recommending surgical treatment, the endodontist assesses the tooth and the surrounding tissues.

This may include discussion of your symptoms and dental history, examination of the tooth and review of appropriate diagnostic imaging.

The purpose of this assessment is to establish the likely diagnosis and consider the available treatment options rather than assuming that surgery is required.

You should also tell the practice about relevant medical conditions, medications, allergies and other health information before treatment.

Where surgery is being considered, the procedure, expected recovery, relevant risks, limitations and alternatives can be discussed before you decide whether to proceed.

What happens during an apicoectomy?

The details vary between teeth, but a typical root-end procedure may involve the following stages:

1. Local anaesthesia

Local anaesthetic is used to numb the treatment area.

2. Accessing the root

A small incision is made in the gum and the tissue is carefully moved to provide access to the bone and root.

3. Treating the affected area

The tissues around the end of the root are examined. Inflamed or infected tissue can be removed and a small portion of the root tip may be removed.

4. Root-end preparation and sealing

Where required, the end of the root canal is prepared and sealed with a root-end filling.

5. Sutures

The gum tissue is repositioned and sutures are placed.

Healing of the gum occurs considerably sooner than changes within the surrounding bone, which can continue over a longer period. Follow-up examination or imaging may therefore form part of monitoring after treatment.

 

Does endodontic surgery hurt?

Local anaesthesia is used during endodontic surgery to numb the treatment area.

Individual experiences vary, and a completely pain-free experience cannot be guaranteed.

Temporary tenderness, swelling or discomfort can occur after surgery as the tissues heal. Your endodontist will provide post-operative instructions appropriate to the procedure and your individual circumstances.

Patients who are concerned about dental treatment can also discuss whether a sedation option is clinically appropriate.

Recovery after endodontic surgery

Recovery varies according to the tooth, the extent of treatment and the individual patient.

Some swelling, tenderness or bruising can occur following oral surgery. Your endodontist will explain how to care for the surgical area and what activities may need to be modified temporarily.

Follow the post-operative instructions provided specifically for you.

If symptoms become severe, progressively worsen, bleeding does not settle, or you are concerned about your recovery, contact the practice for advice.

What are the risks and limitations of endodontic surgery?

Like other surgical procedures, endodontic surgery has risks and limitations.

Depending on the tooth and the procedure, these may include:

  • post-operative discomfort, tenderness, swelling or bruising
  • bleeding
  • infection
  • delayed healing
  • changes to the gum contour or gum recession
  • persistence or recurrence of the original problem
  • the need for further dental treatment
  • failure to retain the tooth.

For some teeth, the position of nearby structures such as sensory nerves or the maxillary sinus may also be relevant to treatment planning.

The nature and significance of these risks vary from person to person and from tooth to tooth. Your endodontist can discuss those that are relevant to your proposed treatment.

Frequently asked questions about endodontic surgery

Is an apicoectomy the same as endodontic surgery?

An apicoectomy is one type of endodontic surgery. It involves treating the area around the end of a tooth root and usually removing a small portion of the root tip. Other forms of endodontic surgery may be considered in different clinical circumstances.

Why would I need surgery after already having root canal treatment?

A previously treated tooth can occasionally develop persistent or recurrent inflammation or infection around the root. Surgery may be considered when accessing or treating the problem through the existing root canal is not appropriate or sufficient.

Is surgery always required when a root canal-treated tooth becomes painful?

No. Pain can have several causes. Assessment is required before deciding whether retreatment, surgery, another dental treatment or monitoring is appropriate.

Can root canal retreatment be performed instead?

Sometimes. Whether retreatment is appropriate depends on the cause of the problem, the existing root canal treatment, restorations, anatomy and other clinical factors.

Will I need sedation?

Endodontic surgery is commonly performed using local anaesthesia. Sedation may be considered for some patients depending on their circumstances and clinical suitability.

Can I drive after endodontic surgery?

This depends partly on the type of anaesthesia or sedation used and your individual circumstances. Patients receiving sedation must follow the specific instructions provided regarding transport and activities after treatment.

How long does healing take?

Soft tissues generally begin healing relatively quickly, while changes in the bone around the root can continue for a longer period. Your endodontist will advise whether follow-up examination or imaging is appropriate.

What happens if surgery does not resolve the problem?

Further assessment would be required. Depending on the circumstances, options may include additional treatment, monitoring or extraction
