Root Canal Therapy

What is a root canal?

A root canal is one of the most common dental procedures performed, well over 14 million every year. This simple treatment can save your natural teeth and prevent the need of dental implants or bridges.

At the center of your tooth is pulp. Pulp is a collection of blood vessels that helps to build the surrounding tooth. Infection of the pulp can be caused by trauma to the tooth, deep decay, cracks and chips, or repeated dental procedures. Symptoms of the infection can be identified as visible injury or swelling of the tooth, sensitivity to temperature or pain in the tooth and gums.

If you experience any of these symptoms, your dentist will most likely recommend non-surgical treatment to eliminate the diseased pulp. This injured pulp is removed and the root canal system is thoroughly cleaned and sealed. This therapy usually involves local anesthesia and may be completed in one or more visits depending on the treatment required. Success for this type of treatment occurs in about 90% of cases. If your tooth is not amenable to endodontic treatment or the chance of success is unfavorable, you will be informed at the time of consultation or when a complication becomes evident during or after treatment. We use local anesthesia to eliminate discomfort. In addition, we will provide nitrous oxide analgesia, if indicated. You will be able to drive home after your treatment, and you probably will be comfortable returning to your normal routine.

Endodontic Presentation

To provide you with a better understanding of endodontic therapy, we have provided the following multimedia presentation. Many common questions pertaining to root canals are discussed.

Endodontic Presentation

What happens after treatment?

When your root canal therapy has been completed, a record of your treatment will be sent to your restorative dentist. You should contact their office for a follow-up restoration within a few weeks of completion at our office. Your restorative dentist will decide on what type of restoration is necessary to protect your tooth. It is rare for endodontic patients to experience complications after routine endodontic treatment or microsurgery. If a problem does occur, however, we are available at all times to respond. To prevent further decay, continue to practice good dental hygiene.

How much will it cost?

The cost associated with this procedure can vary depending on factors such as the severity of damage to the affected tooth and which tooth is affected. In general, endodontic treatment is much less expensive than tooth removal and replacement with an artificial tooth.

Patient Review By Sue J

I have to admit up front that I am not fond of going to the dentist. Fortunately I have not required any procedures other than cleaning my teeth every 6 months for several years. When my regular dentist discovered I had a root absorption she referred me to see an Endodontist. I waited 2-3 week as I really was nervous about that appointment. During that time I researched all of the nearby Endodontists. I’d read the reviews, go back and read again and again. I found myself always going back to Alderwood Endodontics and specifically Dr Wu. When the consult appointment came my Blood Pressure went up as I sat in the chair waiting to meet dr Wu. When she came in her demeanor was calm and reassuring and knowledgeable. Ok. I was going to make the 2 hour appointment for a root canal and an absorption repair. Of course I dreaded the appointment. Day of the appointment everyone calming and efficiently proceeded to numb the area. After 10-15 minutes the technician tested for numbness and it was not numb enough yet. She calmly said she’d have the Dr come back in to make me more comfortable. Dr Wu came in and gave more medication to numb the area. She was not rushed or agitated. She remained calm and sensitive to my comfort level. Next time she came back she was ready to begin. First the root canal, with several X-rays during to procedure to assure the root canal was completed. Staff would always allow a break for me if needed and a time to swallow. Next came the absorption repair. Again done carefully and efficiently with Dr and staff always verbally asking how I was doing. I would highly recommend the office and Dr Wu for any procedure. Although I hope I will not need any more special procedures I would definitely return to this office and Dr Wu. Thankyou staff and Dr Wu!

I would definitely recommend Alderwood Endodontics! Their staff are friendly and knowledgeable. I was able to get an appointment quickly and felt like a valued patient. I was extremely impressed when Dr.Barrineau personally called to check in later that day to ensure I was feeling well and didn’t have any questions! I will most certainly be returning for any future treatments!

Dr. Grace H. Wu was so nice and explained everything in detail even during the procedure. Explaining what she was doing and why, was very comforting and relieved a lot of anxiety I had. Even the music selection was excellent! This is the day after and I'm already feeling relief and doing well. Dr. Grace H.Wu called me this morning to follow up and make sure all is well. I highly recommend her for any procedure! I had a Root Canal done.

Patient Review By Tracy H

I had a dental emergency and was referred to Alderwood Endodontics by my regular dentist and was so appreciative that they were able to get me in quickly given the level of pain I was experiencing. Dr. Bogaert provided an exceptional explanation of the images of the involved tooth and roots. The procedure went smoothly and I appreciated receiving a follow up call to check on my status. Best of all, I was doing so much better even later the same day of the procedure.

Patient Review By Vicki A

My dentist found I needed a root canal. They called while I sat in the chair and got me in immediately! I was walked there from Dr. Robinsons and welcomed by all. The doctor and her assistant were so caring and explained to me what they would be doing. They were kind, they were gentle. There was no pain and no need to worry. I am so thankful and would highly recommend!
