Root Canal Recovery
Saving your natural tooth instead of removing it. Here's what the next week looks like.
Clearing the infection, saving the tooth
Inside every tooth is a soft core of nerve and blood vessel tissue (the "pulp"). When that gets infected or badly inflamed (usually from deep decay or trauma), a root canal removes it, cleans out the hollow root canals, and seals them, like clearing and sealing a clogged pipe so infection can't keep spreading. This saves the tooth instead of extracting it.
Your own tooth, still doing its job
Whenever it's realistically possible, keeping your natural tooth beats replacing it. It preserves normal chewing function, keeps your bite and neighboring teeth exactly where they belong, and avoids the extra time, cost, and complexity of an extraction followed by an implant or bridge. A root canal is also generally far less unpleasant than reputation suggests: most of the discomfort people associate with root canals actually comes from the untreated infection beforehand, not from the procedure that fixes it. Modern anesthesia numbs the area fully, so the treatment itself typically feels no different from a deep filling.

What to expect the day of
Local anesthetic fully numbs the tooth. For upper teeth, numbness is usually limited to the cheek, lip, and gum near the tooth. Lower back teeth typically require a "block" injection, which numbs an entire side of the lower jaw, including the lip, chin, and often the tongue, not just the tooth being worked on. A small access opening is made, the infected or inflamed pulp tissue is removed with fine instruments, and the canals are cleaned, shaped, and disinfected. They're filled with a rubber-like material (gutta-percha) and sealed, and a temporary or permanent filling closes the access opening. A crown (or, if a lot of tooth structure is missing, a build-up first), is typically needed afterward, since root-canaled teeth become more brittle over time.
Eat normally beforehand, since your mouth will be numb for a few hours afterward. You'll be numb for 2–4 hours, and most people return to normal activities, including work or school, the same day. If you're feeling anxious about the appointment, sedation options are available for longer or more involved cases.
Day by day
Days 1–3: Soreness or tenderness when chewing is common as the tissue around the root tip (which was often already inflamed before treatment), settles down. Take ibuprofen or acetaminophen as directed.
Days 3–7: Discomfort should be clearly improving, not worsening.
Ongoing: Avoid chewing on that side until the tooth is fully restored with a permanent filling or crown. It's more fragile until then.
Call us if: swelling develops, pain gets worse after day 3–4 instead of better, or you notice a bad taste or drainage. These can signal a lingering infection.
A note on this guide: this is general guidance. Your treating doctor's specific instructions for your individual case always take priority over anything written here. If something feels off or you're unsure, call us. Don't wait it out.
