Root Canal Retreatment in Plainview
Old root canal hurting again? Retreatment may help save the tooth
A tooth that already had a root canal can become painful again months or years later. Plainview Endodontics evaluates why the tooth has not healed as expected and whether retreatment, apicoectomy, restoration, or another option makes the most sense.
Evaluation for failed, painful, or reinfected root canals
3D CBCT imaging available for complex or missed anatomy
Clear guidance on retreatment, surgery, extraction risk, and next steps
Pain after an old root canal
Biting pain, swelling, or recurring symptoms can happen if bacteria remain or re-enter the root canal system.
Missed or complex canals
Some teeth have narrow, curved, calcified, or missed canals. 3D imaging may help identify anatomy that standard X-rays miss.
Leaking restorations or new decay
A crown, filling, or new cavity can allow bacteria back into a treated tooth and cause new infection.
Root canal retreatment near Plainview for old root canal pain
Root canal retreatment removes previous root canal filling material so the canals can be re-cleaned, disinfected, and sealed again. The goal is to address bacteria, missed anatomy, leakage, or persistent infection while preserving the tooth when it is still restorable.

Why the first root canal may not have healed
A tooth can fail to heal because of complex anatomy, hidden canals, cracks, delayed restoration, a leaking crown, new decay, or infection around the root tip. The reason matters because it determines whether retreatment, surgery, or another plan is most appropriate.
Retreatment vs apicoectomy vs extraction
Retreatment works through the top of the tooth to re-clean the canals. An apicoectomy treats infection surgically at the root tip. Extraction removes the tooth. Dr. Tishbi reviews the tooth structure, imaging, symptoms, and long-term prognosis before recommending a path.
Coordination with your general dentist
After retreatment, the tooth usually needs a final restoration or crown evaluation. Plainview Endodontics communicates with your restoring dentist so the tooth has a clear plan after endodontic care is complete.

Common Questions
How do I know if an old root canal failed?
Symptoms can include biting pain, swelling, gum bumps, recurring infection, or X-ray changes around the root. Some failing root canals have few symptoms and are found on imaging.
Is retreatment painful?
The tooth is numbed for treatment. As with other endodontic procedures, some soreness afterward is possible while the tissues heal.
Is retreatment better than extraction?
It depends on the tooth. If the tooth has enough structure and a reasonable prognosis, retreatment may help preserve it. If the tooth is cracked or not restorable, extraction may be discussed.
Will the crown need to come off?
Sometimes treatment can be done through the crown; sometimes the restoration needs to be removed or replaced. The recommendation depends on access, decay, leakage, and restorative condition.
Do you need my old records?
They are helpful but not required. Recent X-rays, referral notes, and information about prior treatment can make the evaluation more efficient.
