How does a root canal get infected?
A root canal can become reinfected if the final restoration (crown or filling) is delayed or fails, if new decay develops, or if a crack forms in the tooth allowing bacteria to re‑enter. Incomplete sealing of the canals is another possible cause.
- Delaying the final crown is a common reason for reinfection—schedule it as soon as possible.
- Good oral hygiene and regular dental visits prevent new decay on the treated tooth.
- If the tooth feels painful or swollen months later, an X‑ray can determine if retreatment is needed.

Is root canal treatment painful at clinics in Albania?
Modern root canal treatment is performed with local anesthesia and is typically manageable for most patients. Mild soreness afterward is common and usually controlled with prescribed or over-the-counter medication based on your dentist’s advice.
Will I need a crown after a root canal?
Back teeth often need a crown after root canal treatment to protect the remaining structure from fracture. Front teeth may not always require one, but your dentist will decide based on tooth strength and bite load.
How long does a root canal take?
A root canal typically takes between 45 and 90 minutes per visit. Many teeth can be treated in a single appointment, but complex root structures or active infection may require a second, shorter visit.
Does a root canal hurt?
No—a root canal is performed with local anesthesia that numbs the tooth and surrounding area completely. You may feel pressure or vibration, but sharp pain should not occur during the procedure. - Let your dentist know if you feel any discomfort during the procedure so they can add more anesthesia. - Take any prescribed pain medication as directed. - Most patients return to normal activities the same day.
