How long after a wisdom teeth removal can i eat regular food?

As soon as you can: Tolerate it.

Varies: You'll probably want to eat softer foods for the first week to avoid traumatizing the wound. Always rinse after meals to prevent food from trapping in the sockets.

Diet post-ext: a soft high-protein diet for a week or so post-extraction will help promote healing. Avoid heavily spiced foods, alcohol, and don't smoke anything. Keep extraction sites clean, gently rinsing with room temperature water to help remove trapped food debris. By the end of a week you should be able to gradually return to your regular diet. Ask your General dentist or Oral Surgeon for instructions.
