Can I go to work after a root canal?

Most people can. With local anesthetic only, a root canal leaves you numb but not impaired, and there is no standard instruction to take time off. The realistic constraints are the first few hours, when a numb lip makes speaking and eating awkward, and any sedation, which rules out driving and working that day. Book the appointment for later in the day if your job involves a lot of talking or client contact.
- Local anesthetic only
- Same day return is normal
- Awkward numb period
- A few hours
- Any sedation
- No work, no driving that day
- Appointment length
- About 90 minutes per visit
What the first few hours are actually like
You will not be in pain during the appointment, and you will not be in much pain straight after it either, because you are still numb. What you will have is a lip and cheek that do not respond properly, which makes speech slightly slurred on that side and makes drinking messy.
For a lower back tooth, that is often half the lower lip, the chin and part of the tongue. Upper teeth are usually a smaller, shorter lived numb area. If your afternoon is meetings and phone calls, that is the practical problem, not the tooth.
Planning the appointment around work
A few small decisions save a lot of hassle.
- Book late in the day if you talk for a living, so the numbness resolves on your own time
- Book an upper tooth in the morning if you must, since infiltration anesthesia usually wears off sooner than a lower jaw block
- Allow around ninety minutes for the appointment itself, plus travel
- Bring soft food for later, because you cannot eat until the numbness is fully gone
- Arrange a lift home if you are having any sedation
When to take the day
Sedation is the clear one. If you are having anything beyond local anesthetic, you should not drive and should not be making decisions at work, and you will have been given specific instructions about that.
The other case is a tooth that was already badly infected and painful going in. Those teeth tend to be sorest afterwards, and if you were up all night with it beforehand you are unlikely to be much use anyway. It is a reasonable thing to plan for rather than discover at 3pm.
Physical jobs are usually fine. There is no wound to protect and no bleeding risk the way there is after an extraction, though it is worth avoiding anything that has you clenching hard on a tooth that only has a temporary filling.
Managing the rest of the day
Take pain relief before the numbness fully wears off if your endodontist advised it, so you are ahead of the soreness rather than chasing it. Keep lunch soft and on the other side. Do not test the tooth by biting on it to see how it feels.
By the following day most people are simply aware of a tender tooth, which is entirely compatible with a normal working day.
Call your dentist or oral surgeon if
- Pain that becomes severe during the working day rather than gradually improving
- Swelling appearing in the mouth or on the face
- Feeling faint, drowsy or unsteady, especially on new pain medication
- A bitten lip or cheek from eating too soon while numb
- Numbness that has not started to fade by the end of the day
Related questions
Can I drive after a root canal?
Yes with local anesthetic only. No if you had sedation of any kind, in which case you need someone to take you home and you should not drive for the rest of the day.
Will I be able to talk normally?
Not perfectly for the first few hours. Expect slightly slurred speech on the numb side, more so with a lower jaw block. It clears as sensation returns.
Should I take the next day off too?
Rarely necessary. Day one to three is the tender window, but tender is not the same as unable to function. Most people are working normally the day after.

Usually a few hours. Local anesthetic wears off gradually, and the soft tissue numbness in your lip, cheek and tongue lasts noticeably longer than numbness of the tooth itself. Lower teeth typically stay numb longer than upper teeth because the injection blocks the whole nerve to that side of the jaw. Do not eat until it has fully cleared. Numbness that persists past the same day, or into the next day, should be reported.
There is no standard restriction. A nonsurgical root canal does not create a wound in the gum, so most people can return to normal activity the same day or the next, once the numbness has gone. The published aftercare instructions restrict chewing, hot and cold drinks and smoking for the first hour, and say nothing about exercise. The sensible limits are your own comfort, your pain medication, and whether you had sedation.
For the first hour, do not chew, do not drink hot or cold liquids, and do not smoke. Then wait until the numbness has completely gone before eating anything, so you do not bite your lip or cheek. After that, eat soft food on the opposite side, brush and floss as usual but gently around the treated tooth, and stay off the treated tooth entirely until it has its permanent crown or filling.
Most root canal discomfort settles within three to five days. It typically peaks in the first 24 to 48 hours, when the tooth is tender to bite on, then drops off steadily. Roughly a quarter to a half of patients report some pain afterwards, and most of it is mild. Pain that is severe, that lasts more than a few days, or that is climbing rather than falling is the version worth calling about.
