Questions patients often ask dentists at Hanoi Smile before root canal treatment.

- Visits: one or several, depending on the number of canals, infection or retreatment.
- Eating: wait until numbness wears off; avoid hard food on the tooth between visits.
- Is the tooth weaker? Root-treated back teeth are more prone to fracture; a filling or crown is advised.
- Follow-up: X-rays to check healing.
Note: Treatment indications and outcomes depend on each person's oral condition, general health and home care. This article is for general information only; an in-person examination is needed for individual advice.
