It all depends on what was placed after the root canal procedure. In some cases, a temporary filling or crown may be placed, which is more fragile. In others, a permanent filling or crown might be cemented on. It should only take a few days for your tooth to fully heal after a root canal. In that time, be sure to keep your mouth and teeth clean, avoid hard, sticky, sugary, or acidic food and drinks, and try to chew your food on the opposite side if you are experiencing discomfort. If you continue to experience severe discomfort, swelling, or any other unusual symptoms after 5 days, contact us to make an emergency appointment.
