Root Canal Therapy

What is a root canal?

A root canal is one of the most common dental procedures performed, well over 22 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 tissue. It 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 endodontic (root canal) treatment to take out 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 over 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 ensure your comfort. 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 within a few days after root canal therapy has been completed to schedule a follow-up restoration. 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 from Steve H

Over the past 20 years, I have had 3 root canal procedures done by this practice (including at least 1 visit to the DC office, 1 to the Rockville office, as well as today's visit to the Chevy Chase office). Based on my experience, I have 100% confidence in the knowledge and expertise of the doctors. Moreover, in all 3 cases, the root canal treatment was entirely successful, with no complications. Everything was handled with precision and professional.

Patient Review from Jeren M.

Dr. Simon is always a pleasure to work with. I had a consultation with him about 2 years ago. This time I needed a root canal done. He did an excellent job with my tooth. He communicated all the steps and was sensitive to my needs during the therapy. The process seemed shorter with this practice and that’s probably due to the expertize and poise of Dr. Simon. Also, Brandy (the front office) was extremely helpful with the forms. I felt that I was in excellent hands during the whole process!

Patient Review from Joie P

As he did the root canal, Dr. Simon explained what he was doing and what to expect. I tend to be an anxious dental patient, but he and Sue put me at ease. Brandy and Laura were very helpful when I arrived st the office, and when I paid following the procedure. Especially grateful that they could fit me in on Christmas Eve morning! I have already let my dentist know how pleased I was with Dr Simon, and gave recommended him to others.

Patient Review from Richard R

A root canal is a frightening thought and experience to an 81-year-old. The staff at both the Chevy Chase and Rockville staff were excellent. I forgot to premedicate for my follow up visit at the Rockville facility today. I was quickly and cheerfully provided with the needed medicine. While working, Dr. Simon provides information as to what he is doing and reassurance to the helpless patient. To me, that is critical. While I would not recommend anyone have a root canal, I would recommend Dr. Simon and Advance Endodontic Associates to perform it.
