“Doctor, I already had a root canal. Why is this tooth hurting again?”
It’s a question many patients understandably Had a root canal… but the same tooth is hurting again?
It can be frustrating. You went through the treatment, the tooth felt fine, and months or even years later, discomfort returns.
A previously treated tooth may develop problems because of:
🔹 A hidden or missed canal
🔹 Complex root anatomy
🔹 Leakage beneath an old filling or crown
🔹 Persistent or recurrent infection
🔹 A crack in the tooth
Here’s the important mindset shift:
A failed root canal does not automatically mean the tooth has to be extracted.
In suitable cases, Root Canal Retreatment allows the tooth to be reopened, carefully evaluated, disinfected and sealed again.
Modern magnification, digital imaging and advanced endodontic techniques can also help identify problems that may have been difficult to detect during the original treatment.
At Dr Deval Mehta™, the priority is to understand why the tooth has become symptomatic and determine whether preserving your natural tooth is clinically predictable.
⚠️ Pain while biting, swelling, a recurring gum boil or discomfort around an old root canal should not be ignored.
