Question 1

How successful is endodontic retreatment?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Endodontic retreatment has a success rate of up to 85% when performed by an experienced endodontist using modern techniques and technology. The success rate depends on factors such as the reason for failure, the complexity of the case, and the patient's overall health.

Question 2

Is retreatment more painful than the original treatment?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Retreatment is typically no more uncomfortable than the original root canal treatment. We use advanced anesthesia techniques and offer sedation options to ensure your comfort throughout the procedure. Most patients experience significant pain relief after retreatment.

Question 3

What are the alternatives to retreatment?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

If retreatment is not suitable or unsuccessful, alternatives include endodontic surgery (apicoectomy) or tooth extraction followed by replacement with a dental implant, bridge, or partial denture. However, saving your natural tooth through retreatment is usually the preferred option.

Question 4

Why did my first root canal fail?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Root canal failure can occur due to narrow or curved canals that were difficult to treat initially, complicated canal anatomy that was missed, new decay that exposed the root canal filling to bacteria, a loose or cracked filling or crown that allowed bacteria to re-enter, or a delay in placing the final restoration.

Question 5

How long after root canal can problems occur?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Problems can occur months or even years after initial root canal treatment. Some issues develop immediately, while others may take years to become apparent. This is why regular dental checkups and X-rays are important to monitor the health of treated teeth.

Question 6

Is retreatment covered by insurance?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Most dental insurance plans cover endodontic retreatment, typically at the same percentage as initial root canal treatment (usually 50-80%). We will verify your benefits and provide a treatment estimate before beginning treatment. We also offer financing options if needed.

Question 7

How many times can a tooth be retreated?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

There is no specific limit to the number of times a tooth can be retreated, but each subsequent treatment may have a lower success rate. The decision depends on the tooth's condition, the reason for previous failures, and the likelihood of success. Dr. Nima will evaluate each case individually.

Question 8

What are the warning signs I need retreatment?

Dr. Nima Dejbod, DMD - Vice President, Washington State Association of Endodontists · Accepted Answer

Warning signs include pain when biting down or chewing, prolonged sensitivity to heat or cold, discomfort in the tooth, swelling or tenderness in the gums near the tooth, or discoloration of the tooth. If you experience any of these symptoms in a previously treated tooth, contact us for evaluation.
