By definition, after root canal treatment is completed there should not be any pain on the particular tooth. The pain could be because of improper treatment or a filling which is protruding out and causing excessive pressure on the tooth which leads to pain. If the pain doesn't subside ,you need to visit the dentist who performed the RCT.

Hi, There will be pain in the tooth for a few days. Start eating on that side after 2 days.

Since you have got a root canal treatment just yesterday, it is normal to feel pain and tenderness with the associated tooth as root canal treatment is a procedure where the tooth is instrumented and cleaned and then filled till the root end and the pain may be because of the same. However, you will notice that the intensity of the pain will gradually reduce. Since the capping will take 1-2 weeks, I would suggest just scale your pain on from 1 to 10 depending on the intensity and compare it on days 3, 6 and 10th day to know if it has improved! In the mean time, your Dentist will do the needful process of preparing the tooth for cap and before the final cementation of cap you will understand if you are pain free or no.

Hello It’s normal to have pain post RCT for a few days nothing to worry about it
