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.

Not hard to get scheduled. I saw Dr. Wu and enjoyed her relaxing professional manner. Consultation was explained really well. I had a root canal, my 1st, and it went so well during and afterwards. Would refer for sure. My regular dentist referred me.

I liked how engaging the staff was. And I liked the calm attitude that Dr. Bogaert had--even enjoyed hearing him hum sometimes during my visits. During the procedures, I was continually asked how I was doing.

Referred by Cedar View Dental to have root canal consultation. The scheduling was a breeze with Jennifer over the phone. In my initial in person visit; I was welcomed by Jennifer and the consultation went well. Scheduled for a Canal and that was on time. Chelsea, answered all my questions and, It was mentioned to expect a follow - up cal from Dr. Barrineau. Overall, the staff seem to get along well, and I had relatively painless procedure. I would recommend Alderwood Endodontics for their staff and location.

Root canal was painless, even when several hours later after numbing sensation went away I didn't have pain. Next day, like nothing happened. Thank you for wonderful care.

Patient Review By Mark B

DR Wu and her staff were exceptional. I came in for a root canal expecting pain and discomfort. I left there in amazement. I had no pain through the entire process. Dr Wu gave me step by step notification on her procedure. I would defiantly recommend Alderwood Endodontics. Thank you, Dr Wu and staff.

Patient Review By Ginny S

Having had 2 previous root canals, I was nervous about my third one. But I worried needlessly because from the numbing injections, which Dr. Wu did slowly so as not to cause much pain, to the procedure itself and afterwards, I felt almost no pain at all. I didn't even need Tylenol post-procedure! I can't recommend Dr. Wu highly enough.

Patient Review By Kim H

Dr Wu did a fantastic job on my root canal and I'll definitely be back! I have severe anxiety because of several prior experiences with doctors who were unable to numb me up. The staff was so kind, Dr Wu talked me thru every step of the process, and I had no pain at all. I enjoyed listening to her golden-doodle's escapades - I couldn't help but laugh. Thanks again for the top-notch care! 🙂
