After Root Canal

Endodontic treatment can take 1, 2 or 3 appointments depending on each case. It is possible to experience any of the following symptoms after any one of these appointments: sensitivity to hot and/or cold; sensitivity to pressure; possible swelling. Follow up with any placement of your permanent crown as you have been advised. Any unnecessary delay on placement of final crown may damage the tooth permanently.

For the First hour

Usually a temporary filling has been placed on your tooth.

  • Do not bite on the tooth for one hour and while you are numb.
  • Try to chew with the opposite side.


Some patients will experience swelling after root canal has been completed. It may be mild or sever, and is different for every patient. The swelling (if any) can get bigger for the first 24 to 48 hours before it starts to go away.

  • Use an ice pack (frozen peas work really well) on the cheek or face next to the surgical site. Keep it on for 15 minutes, then off for 15 minutes and repeat until you go to sleep.
  • Sleep with your head elevated slightly, above the heart. This will keep swelling down.


You may experience moderate pain and sensitivity on that tooth.The healing process may take several days but the pain and discomfort should subside gradually.

  • Sensitivity to hot and cold is normal.
  • Sensitivity to pressure when you bite is also normal
  • You may feel gum soreness for a few days after your treatment.


Take any medication that was prescribed to you according to instructions.


Continue your brushing and flossing.


Be gentle on the tooth while eating until the final restoration is placed.
