Can a root canal cause a sinus infection?
A root canal itself does not cause a sinus infection. However, an infected upper tooth (especially a molar or premolar) can sometimes be mistaken for a sinus problem because the roots are close to the sinus cavity. The root canal treatment actually resolves the dental infection, which may also relieve sinus‑like symptoms.
- Dental infections in upper back teeth can mimic sinusitis.
- A root canal treats the tooth infection; if sinus symptoms persist, see a doctor.
- Always inform your dentist about any sinus or allergy history.

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.
