How long till you can eat after tooth extraction?

Depends: Fluids and calories are important for healing. At least wait until the local anesthesia wears off. Then, if the extractions were just on one side of the mouth, you can carefully eat on the other side of your mouth. If teeth were extracted from both sides of the mouth, like 4 wisdom teeth, i recommend clear then full liquids the first day, then soft foods for 4 to 7 days.

No novocain (procaine): As soon as the anesthetic wears off. Otherwise you can bite your lip/tongue.

Advice of dentist: Follow instructions from your dentist/oral surgeon. Will depend on severity of the removal.
