Once you have had a root canal, it is advisable that one waits until the numbness has gone way before eating solid food. Most of dentists recommend beginning with a soft diet and then resuming the regular one when it becomes comfortable. But you should follow your dentist’s exact instructions as recovery may differ depending on the person and type of procedure. Seek professional advice from a dentist on the right steps to follow after treatment.

1. After a root canal, you can’t eat for 30 to 45 minutes to give your temporary filling enough time to properly firm. 
2. However, it's usually advised that patients wait to eat until after the anesthesia wears off to avoid biting their cheeks or tongue. 
3. To maintain the region clear of food particles and plaque, be sure to brush and floss often.
4. You should also consult with your dentist regarding what you can eat and what you should avoid after your root canal.
