Frequently Asked Questions
Can I drive after a root canal with local anesthesia?
Yes. Local anesthesia (numbing injection) only affects your mouth, not your thinking or coordination. You can drive safely with a numb mouth.
Can I go to work after a root canal?
Many people return to work the same day. Your mouth will be numb for a few hours, and you may have mild discomfort, but there's no medical reason you can't work if you feel up to it.
How long does numbness last after root canal?
Typically 2-4 hours. Lower teeth often take longer to recover feeling than upper teeth. You can function normally but should avoid eating until feeling returns.
