Northshore Endodontics | Kenmore, WA – Serving Greater Seattle
Most of us think of a root canal as the final step in resolving deep tooth pain or infection. And in many cases, it is. But occasionally, a tooth that has received root canal therapy does not heal as expected — or begins to cause discomfort again months or even years later. This is where endodontic retreatment comes in: a second chance to save your natural tooth, restore function, and relieve pain without resorting to extraction.
At Northshore Endodontics, located in Kenmore, WA, Dr. Elena Andronova and her experienced team specialize in diagnosing and treating complex cases through retreatment. Serving patients throughout Greater Seattle, including Kirkland, Bothell, Shoreline, and Bellevue, the practice is known for its precision, compassionate care, and advanced technology.
Why Might a Tooth Need Endodontic Retreatment?
Root canal treatment has a high success rate, but several factors can lead to persistent or new problems in a previously treated tooth:
- Hidden or curved canals that were not treated during the initial procedure
- New decay that exposes the root canal to bacteria
- Defective crowns or fillings that allow recontamination
- Fractured or loose restorations
- Delay in placing the permanent restoration after treatment.
These complications can lead to continued inflammation, infection, or discomfort. Rather than removing the tooth, retreatment can provide a cost-effective and long-term solution while maintaining your natural smile.
Northshore Endodontics’ Specialized Approach
At Northshore Endodontics, retreatment is approached with the same meticulous care and clinical precision as a first-time root canal—but with even greater attention to detail due to the complexity of these cases. Dr. Elena Andronova, a board-certified endodontist and founder of Northshore Endodontics, has been delivering advanced endodontic care since 1994. Her experience and dedication make her one of the most trusted names in the field across the Seattle area.
Here’s how the retreatment process works:
1. Thorough Evaluation and Diagnosis
Every endodontic retreatment begins with a detailed clinical and radiographic examination. Dr. Andronova uses modern tools like digital imaging and high-resolution microscopes to identify the root cause of the failure. Whether it’s a missed canal, a fracture, or a restoration issue, she ensures nothing is overlooked.
2. Careful Removal of Previous Root Canal Material
Using ultrasonic instruments and specialized files, Dr. Andronova gently removes the previous filling material inside the tooth. This step is performed with great care to preserve as much of the natural tooth structure as possible.
3. Cleaning, Shaping, and Disinfection
Once the canals are accessible, they are meticulously cleaned, reshaped, and disinfected to eliminate any lingering bacteria or debris that may have caused reinfection.
4. Refilling and Sealing the Tooth
The canals are then filled with advanced biocompatible materials and sealed to prevent future infection. Finally, your general dentist will place a new crown or restoration to protect the tooth and restore full function. We work with Dr. Yelena Chuvashova at Birch Dentistry in Issaquah. Feel free to contact the dental office to schedule further treatment.
A Patient-Centered Experience
At Northshore Endodontics, endodontic retreatment is not just about technical skill—it’s also about ensuring the patient feels safe and comfortable every step of the way. The practice offers:
- A relaxing, spa-like environment
- Movie goggles and comfort amenities
- Gentle, compassionate communication
- Flexible scheduling for urgent cases
Whether you’re nervous about dental procedures or simply seeking a second opinion, the team at Northshore will take the time to explain your options and ensure you feel confident in your care plan.
Preserving Your Natural Smile
Retreating a tooth rather than extracting it is almost always the healthier and more cost-effective choice in the long run. Keeping your natural tooth helps maintain the alignment of surrounding teeth, preserves your ability to chew comfortably, and avoids the need for implants or bridges.
Schedule a Consultation
If you’re experiencing pain or swelling in a tooth that has already had a root canal—or if your dentist recommends retreatment—trust the experts at Northshore Endodontics to evaluate your case. Dr. Elena Andronova’s expertise, coupled with a commitment to patient care, ensures you’re in the best hands.
