Endodontic Retreatment

With the appropriate care, your teeth that have had endodontic treatment will last as long as other natural teeth. Yet, a tooth that has received treatment may fail to heal or pain may continue to exist. Sometimes, the pain may occur months or years after treatment. If so, Endodontic Retreatment may be needed.

Improper healing may be caused by:

  • Curved or narrow canals that were not treated during the initial treatment.
  • Complicated canals that went undetected during the initial treatment.
  • The crown or restoration was not placed within the appropriate amount of time following the procedure.
  • The crown or restoration that did not prevent saliva from contaminating the inside of the tooth.

In some cases, new problems can influence a tooth that was successfully treated:

  • New decay can expose a root canal filling material, causing infection.
  • A cracked or loose filling or crown can expose the tooth to new infection.

Once retreatment has been selected as a solution to your problem, the doctors will reopen your tooth to gain access to the root canal filling material. This restorative material will be removed to enable access to the root canal. The doctors will now clean your canals and carefully examine the inside of the problematic tooth. Once cleaned, the doctors will fill and seal the canals and place a temporary filling in the tooth.

Call us with any questions or to make an appointment.


At this point, you will need to return to your dentist as soon as possible in order to have a new crown or restoration placed on the tooth to restore full functionality.

Patient Review by Rebeccah R

Very promp, professional, and honest care. The endodontist told me he didn’t think he could save my tooth, and gave me his honest and affordable advice. Greatly appreciated!

Patient Review by Robert M

This office is very professional and Dr. Petterson is the best. He explained everything about the procedure so I would understand every step of the way. Constantly checked to see if I was okay. It's a relief to have a Dr. that you can carry on a conversation with .

Patient Review by Elizabeth D

Beautiful office! Very peaceful atmosphere. Dr. Silberman was caring and gracious. He took a lot of time to explain my problem. He also opted for a wait and see approach on a problematic tooth, instead of rushing to a surgical one that would have been expensive and require some recovery time. He also didn't rush me out. The supporting staff went out of their way to make sure I was comfortable and not in any pain during the exam. Very impressed. Will return if necessary.

This was by far the BEST experience I have ever had during a dental procedure, Dr. Silberman you are amazing! I was in so much pain prior to my retreat and you somehow made this a quick and painless procedure. I appreciate you and your assistant beyond words. Thank you!

Patient Review by Helene S

I’ve been visiting Dr Petterson’s ofc as needed over a period of 25 years and value his work so much I currently pay out of pocket to see him as all other endodonists in my Plan are simply dentists DOING endology and are not a board certified specialist as Dr Pettersen is.

Patient Review by Valerie G

Dr. Pettersen is great and made a dreaded procedure a positive, painless experience. Unfortunately this was a second tooth that had to be worked on and I arrived at the appointment confident that he would listen and be sensitive to my needs.

Patient Review by mike f

I loved the entire experience of this office, its staff, and doctors and assistance. My root canal was failing, and within two days of calling, I had an appointment. The waiting room and office is very warm and welcoming, they even have a tv with a headset that they give you so that you can watch your favorite TV shows while they are working on you.

Patient Review by Ciri R

I have a long history of bad teeth and serious dental anxiety. Doctor Silberman is AMAZING. Best chair-side manner of any endodontist or any other type of dentist I have ever been to. And that is saying a lot because I have had a ridiculous amount of dental work (many root canals) in my 40 years of life! He and his assistant were friendly and reassuring and walked me (so to speak) through the whole procedure, checking to make sure I was doing okay every few minutes. They also have TVs in the ceiling, which is a nice distraction when you hate being in that chair. I highly recommend this place. The whole entire staff was lovely.

Patient Review by Dan K

Everyone was superb in both their professionalism and care! All were very kind and constantly asking me if everything was okay (when in the chair) and are you okay, etc. Treated me like a king! It was definitely worth paying out of pocket to come here and get the BEST treatment possible, both from the doctor and from the entire staff!

Patient Review by David B

Dr. Pettersen and staff are top notch. The office is inviting and almost spa-like. Personable, professional and efficient. I've been referred from my primary D.D.S. to Dr. Petterson a number of times. Without fail, exceptional dental care, always a positive pain-free outcome.

Patient Review by John R

So I went to see Dr. Silberman for an abcess on tooth #14. Dr. Silberman said he had to redo a previous root canal and not just do the 3 original roots, but also a 4th that he found. To be perfectly honest, it was as if he gave a deep cleaning on one tooth. I did not feel the numbing shots and he was very conscious of my comfort. He constantly updated me as to his progress and insured the job was totally to his high standards. The office staff and assistants are all very friendly and professional. Thank you for making an anticipated unpleasant experience relatively bearable.
