Sarmiento Microendodontics

Endodontist located in Cypress, TX

Up to 95% of initial root canals are successful. However, if a tooth becomes re-infected or a patient experiences persistent pain in an endodontically treated tooth, endodontic re-treatment may be necessary to remove bacteria from infected tooth roots and save your tooth from needing an extraction.

Endodontic Re-Treatment Q & A

What is endodontic re-treatment?

Non-surgical re-treatment therapy removes previously existing root canal filling material and additional root canal therapy on a diseased tooth. Typically, this treatment takes one or two visits.

Why would I need endodontic re-treatment?

Some reasons that root canals fail include:

  • Complicated anatomy or undetected canals during initial therapy
  • Incomplete removal of infected tissue
  • Bacterial contamination under defective restoration
  • Recurrent decay
  • Crown or root fracture

As bacteria invade the affected tooth, the root canal system becomes contaminated and re-infected. Patients may experience tenderness to biting/chewing, tender/swollen gums, or may note a pimple on the gum near the affected tooth.

How is endodontic re-treatment performed?

After administering local anesthesia, a rubber dam (shield) is placed to isolate the affected tooth. This shield is a vital component of endodontic therapy, as it serves to keep the tooth dry and sterile throughout the procedure. 

If a crown is present, Dr. Sarmiento will likely access and perform the treatment through the restoration rather than removing it. If the affected tooth contains a post, it will be removed using small instruments. 

Once the canals are located, the compromised filling material is removed. Untreated canals, if present, will be located at this time. The canals are then disinfected, cleaned, shaped, and ultimately filled and sealed.

A temporary restoration is placed within the access opening until Dr. Sarmiento places a permanent restoration, such as a filling or a new crown. The permanent restoration acts to protect the treated tooth from recurrent disease or fractures.

Teeth that are properly restored following root canal therapy have a much better chance of survival. Endodontically treated teeth function normally and can last a lifetime with proper oral hygiene. 

What if the tooth is cracked?

If the tooth has a visible crack, the patient will be notified and advised that the tooth must be extracted. The cracked tooth will be temporarily sealed with a restoration until it can be removed.

What is expected after endodontic re-treatment?

Patients may experience tenderness or discomfort in the area for 2-3 days after treatment. Over-the-counter medications are encouraged to relieve these symptoms. Patients are encouraged to contact their general dentist about one week after treatment to schedule an appointment to complete the restoration. 

However, if a patient has ongoing discomfort or experiences visible swelling, the permanent restoration should not be placed, and Dr. Sarmiento should be contacted immediately.
