You might feel pain in teeth after few days after the procedure and swelling would heal gradually over a period of time which can vary patient to patient. There might be a feeling of altered sensation in comparison to other healthy natural tooth. In order to keep your newly root canal treated tooth clean and plaque-free, brushing, flossing and inter-dental brushes are a must. After RCT, is it strongly advised to get a crown over the root canal treated tooth to prevent its accidental fracture or re-infection otherwise all the efforts and time made to save the tooth would go waste. Periodic follow-up visits will be scheduled to monitor your restored teeth and gums to make sure they are healthy.
