Root Canals Ask The Endodontist Christopher McFarland Question:
I just got my root canal done for #30 (right side lower molar).

How long should I wait before I go for the crown to make sure that tooth is not having any infection left even after root canal and RC is done properly?

Just curious that why do they give very heavy dose of Advil and extra strength tylenol after RC for 48 hours, even if there is no pain. ... Visitor from GA

Good question because the last thing anyone wants is to fracture a tooth after the root canal is finished and before you can get it restored with a new crown.

For most people 1-2 weeks is plenty, assuming there is no pain or swelling. Be careful with chewing on that tooth since the tooth has been weakened when the opening for the root canal was created. RCT procedures are also known to typically affect the nutrient supply to the tooth strucure.

Advil is commonly recommended to take care of any residual inflamation that might be present at the ends of the root of the tooth.

600mg three times a day for a couple days is always a good idea.

In our office, my associates and I have found that the root canaled teeth that do the best over time (have best endurance) have a post placed in the root to strenghen that part of the tooth that holds the crown in place.

Hope this helps you!
