Root Canal Therapy in Hooksett, NH

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.

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.

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 (usually a crown). 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 (dental implant).

Dr. Katz and his staff are the best!!! They were great at helping me relax and feel comfortable. Dr. Katz spent the time needed to take care of the tooth that was infected and in very poor shape. He was therefore able to save the tooth. I highly recommend Dr. Katz. I honestly didn’t feel any pain at all.

By the time I got around to visiting my regular dentist I was in considerable pain. She arranged for me to see Dr. Katz, and he managed to fit me into his schedule that same afternoon. The needed procedure, a root canal, was complex because of the number of canals in the tooth. I have just completed the follow up visit and consider myself extremely fortunate to have his level of skill available. The receptionist and the two dental assistants that worked on me were also highly skilled and very friendly. I am ... pretty old. Enough so that I have been going to the dentist since the 1950s, and I have had good and bad experiences. I would judge Dr. Katz and his team to be exceptional, and would recommend him without reservation.
