Questions about root canal treatment
Is root canal treatment painful?
The treatment is done under local anaesthesia, so you should not feel pain during the procedure. Mild tenderness for a few days afterwards is common and usually settles with the pain relief your dentist advises.
How many visits does a root canal take?
Many teeth can be completed in one or two visits. The number depends on how severe the infection is and how many canals the tooth has. We confirm this after your examination.
Do I need a crown after a root canal?
Often yes, especially for back teeth, because a root canal treated tooth is more likely to crack. Dr. Saxena will advise what suits your tooth.
Is it better to extract the tooth?
Saving your natural tooth is usually the better option when it can be restored. If a tooth cannot be saved, we will explain why and talk through replacement options.
