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.
Contact Our Office Today...
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 procedures, we have provided the following multimedia presentation. Many common questions pertaining to root canal therapy are discussed.
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 Gary H
Dr Wu was outstanding. My tooth that needed attention is the anchor for a bridge and was difficult due to decay under the crown. In the end the result was an incomplete root canal as Dr Wu wanted to have my primary dentist check to see if the tooth is salvageable. If so, we will be back to complete the root canal.

Patient Review By John S
The treatment went very well. No pain.
- John S
Patient Review By Sara G
I liked the ongoing explanations of the procedure by Dr Wu to help me feel at ease before and during my root canal. She answered my additional questions as well. The way novacaine is administered is virtually pain free and swelling doesn't linger after the procedure. Recommend.

Patient Review By Sonia G
Great clinical experience and a painless root canal as well excellent customer service. A small issue was the final cost being higher than the initial estimate due to insurance limits. I highly recommend Alderwood Endodontics.

Patient Review By Tony B
I was very uneasy about my first- ever root canal. From my first consultation, every staff member made me feel at ease. On Root Canal Day, Dr Wu, assisted by Cali, did an outstanding job and kept me informed at every step. I had no pain during the procedure and none since! I will recommend Dr Wu and the Alderwood Endodontics team enthusiastically. Thank you! You guys are the best.

Patient Review By Jon C
What can I say? There were condolences from friends about needing a root canal. Dr. Wu was amazing. I slept through most of the procedure and there's no pain and little discomfort following. That may not be everyone's experience, but it sure was mine.
- Jon C
Patient Review By Giovi A
Dr Kang performed the procedure. I was very impressed with the attention to detail that he showed. You can clearly tell that he loves his work and performed it with experience and expertise. I have already recommended him to coworker and friends and the procedure was a little more than a week ago. I’m not one to write a review or recommend anything to anyone because it’s is unfortunate that so few people have high standards and skills. Dr. Kang has both and I felt compelled to acknowledge his dedication and commitment to providing excellent work. Thanks for being there for me and doing such a great job. Sincerely, your patient for life Chris G.

Patient Review By Melanie W
Front desk people were polite and handled all the new patient information quickly. Dr Kang was exceptional. Explained everything and had a light touch while doing the root canal. Absolutely no pain afterwards. Dental assistants were great too!!
- Melanie W
Patient Review By Jacqueline S
I felt I was visiting friends at the clinic. Staff was great from the start, with the front desk, dental assistant/hygienist, and of course, Dr. Wu. I got in the next day after getting recommended by my dentist to have an evaluation of my tooth/gum pain. My pain got worse overnight by the time I saw Dr. Wu. She was able to schedule me within 1 hour after the evaluation to get a root canal. I was SO relieved I did not have to wait another day, being in SO MUCH pain, She saved me from using more sick time by getting me in quickly. Dr. Wu was so thorough in her explanation of everything and took her time. HIGHLY recommend her and her staff!!!

Patient Review By Glenda Diane C
Dr Wu explained that it was a difficult root canal, but she was going to try. She was extremely careful about going gently and doing all she could to keep me comfortable. I don't ever remember any dental procedure that was as reassuring. I had never had a root canal, but had heard many stories. This was as good as it could get, I believe and she was able to get it done. Thank you Alderwood Endodontics!
- Glenda Diane C
Patient Review By Barbara S

Patient Review By Kevin D
Everyone was courteous and professional. Treatment was explained and conducted well. As with anything in the American health profit system, be prepared for high expenses, especially if you don't have adequate insurance coverage.

Dr Grace Wu is has excellent expertise performing root canals, explains every step as she works, and is very friendly. She also made a special effort to quickly interpret an imaging test result after I left the initial evaluation appointment. Her assistant was also proficient and nice!

Patient Review By KATHIE D
This was not my first root canal procedure, but it was my first visit to this clinic. It was also my first time to need a "repair" of an old root canal that was causing intermittent pain. The entire team was helpful and very careful to explain things every step of the way, from scheduling, procedure and explanations of after care. THANK YOU!! My mouth was feeling great the very next day!
- KATHIE D
Patient Review By Holly H
I appreciate and thank Dr Wu and her awesome assistant. I’m not an easy patient. Mouth appointments are not my favorite way to spend my time. But it’s the only way to keep my teeth. And now I know I can trust Dr Wu and her staff if I need them in my future. Thanks again!!

Dr. Barrineau made me feel so comfortable and was as gentle as possible. My recovery time was only 2 days. She explained the process before we began.

The procedure from start to finish was stress free. Dr. Grace Wu and her Assistant are dialed into Patient comfort. They both asked to be informed of the slightest discomfort. I left the office with no pain whatever. I had fallowed the pre-appointment suggestions of taking two Advil before Procedure and two that evening, it's a been week and never any Pain.

As a person of whom is naturally very nervous about coming to see a Dentist, or have any form of Dentistry work done, I found myself incredibly calm during the entire procedure. The overall atmosphere of the office, and extremely patient staff, helped tremendously through my Root Canal Procedure. I shall be coming to your office for future visits, and am beyond grateful for everyone's kindness/patience!

Patient Review By Gerry A
This was my 7th root canal in my lifetime since I had crowns and bridges put in over 10 years ago. I think I've had approximately 2 now at Alderwood Endontics. All the staff were a pleasure to work with and completely understanding of my concerns in the procedure.
- Gerry A
Patient Review By Douglas M
I am very pleased with the care I received from Dr. Owart and his entire office! I would not hesitate to recommend them to anyone in need of their expertise. TI was rereferred to them on the Monday morning before Thanksgiving, had my first visit on Tuesday and they took care of my root canal on Wednesday! I was able to enjoy Thanksgiving and travel out of town to a wedding on Friday without a worry! A BIG THANK YOU to Dr. Owart and all of his Staff!

- Ted L
Patient Review By Andrea C
Dr. Owart and his assistant were incredible kind, gentle, and calming. I was at my dentist's office for a toothache, and within an hour, sitting in Dr. Owart's chair for a root canal. Needless to say, it was an unexpected procedure, and one that I've never had before. I had a great deal of anxiety! Dr. Owart was very empathetic to my anxiety, and went above and beyond (in my opinion) to make my experience comfortable and pain-free!
- Andrea C
Patient Review By Diane B
Dr Owart, while incredibly young compared to my age was very kind, empathic and knowledgeable. I have a Dentist in my family and he reminds me a lot of my cousin with his chair-side manner. I have recommended Dr Birkin to two of my retired dentist's friends. I had to wait for a month before I wrote this review just to make sure there were no problems. I can now say it has been the easiest root canal I have ever experienced. Thank you Dr. Owart.
- Diane B
Patient Review By Kim B
I had a root canal performed by Dr. Owart on August 21, 2024, and I couldn’t be more impressed with his care and professionalism. Although a root canal was not something I ever wanted, Dr. Owart took the time to thoroughly explain each step of the process, which eased a lot of my anxiety. The procedure turned out to be more challenging and time-consuming than expected, lasting 3.5 hours instead of the anticipated 2. However, Dr. Owart made sure I was comfortable and pain-free throughout the entire process, which was a major concern for me. His dedication to ensuring I had a positive experience despite the difficulty of the procedure was greatly appreciated. I highly recommend Dr. Owart for his expertise and compassionate care.

Dr. Bogaert and his assistant were very compassionate during my procedure. The procedure was also pain-free, something I did not expect.

Patient Review By Cassandra P
I was very grateful to be worked in so quickly for this visit and Chris at the front desk was wonderful. She was by herself and I could hear how patient, calm and kind she was to patients. I had a root canal procedure done with Dr Barrineau and her assistant Frieda. Frieda was absolutely amazing! She was very informative and let me know everything she was doing every step of the way, she was also super nice. Dr Barrineau had the most amazing bedside manner and made the procedure seem not so bad. She was very efficient and you could tell that she knew what she was doing, she was also very friendly and talked to me the whole way through, which I find is not common with dental providers. My procedure was a little complicated and ran late and I did not feel rushed at all, I felt very well cared for. I have a history of dental fear and have had a lot of dental procedures in my lifetime, this is one of the best experiences I have ever had. Thank You!

Had a root canal gone bad. Dr. Wu is so kind and explains all steps of the procedures well before starting. This tooth had 4 roots. The followup X-ray showed them all evenly filled.

Patient Review By Waiyan A
I have never seen a dentist who sang a country song while performing the root canal procedure. She is very energetic and hardworking. I did not feel any pain throughout the procedure. If you want a dentist who loves country music and with a positive energy, I recommend scheduling an appointment with Dr.Bara. I hope she stays this way because it is hard to find a person who is free spirited these days.

From the time of making the appointment I was OK. I am Elderly and have been around a lot, but my first time to a tooth specialist. I have certain medical issues that require attention to. All was performed so perfect. From The beginning to the End. I would Highly recommend Alderwood Endodontics to any one. Young, Middle Age, and certainly the Elderly. So very important to me was the telephone call in two days by Dr Wu to see how all was going and any concerns. I thank all for being a fantastic perfect ( like the old days) clinic.

The N2O cost an additional $120. Also, they gave me over-the-counter drugs. Last time I had major dental work, the DDS gave me Percocet™, good stuff.

Patient Review By WILLIAM C
I was deeply disappointed that I was only given over-the-counter drugs and N2O was a $120 extra. Back when I was a kid, they gave out bottles of Percocet™, and while we couldn't take the N2O home, it was free while in the Chair (in-cathedra).

Patient Review By Anthony W
I would highly recommend Dr. Barrineau if you need a root canal. She is an excellent dentist and was well trained. I had little if any pain during the process, which is a vast change from a previous root canal by a different clinic.
