How to Care for Your Tooth After a Root Canal
rootcanaltherapy
A step-by-step aftercare plan for the days and weeks following a root canal, from managing soreness to protecting the tooth until your crown is placed.
Your root canal is done — now the goal is a smooth recovery and protecting the tooth until the permanent restoration is in place. Here's what to do, day by day.
The first 24 hours
- Wait until the numbness wears off before eating so you don't bite your cheek or tongue.
- Take any prescribed or recommended pain reliever on schedule, not just when discomfort peaks.
- Chew on the opposite side, especially if a temporary filling is in place.
- Skip very hot foods and drinks while your mouth is still numb.
Days 2–7
- Mild tenderness when biting is normal and usually fades within a few days.
- Keep brushing gently and flossing carefully around the treated tooth.
- Rinse with warm salt water if the gum feels tender.
- Avoid hard, crunchy, or sticky foods (nuts, ice, caramel) on that side.
Until your crown is placed
A tooth that has had a root canal is more brittle than a healthy one. Most back teeth need a same-day CEREC crown to restore strength — don't delay this step, since an unprotected tooth can crack.
