How soon should i be able to eat regular and spicy foods after wisdom teeth extractions?

When the hole closes: Until the hole in the gum and bone closes you should watch what you eat. Spicy or hard foods can injure the area or at the very least cause pain. If you're in doubt, call the dentist who removed them or go see him/her.

2 - 7 days: It depends on the severity of the impact ions. Your surgeon will advise you accordingly.

That varies: There is a wide range of post operative healing outcomes based both upon the type of extraction\impaction and the recuperative powers of the individual. For a simple wisdom tooth extraction, you can probably resume normal eating habits within a day or two; for a severe impaction, it might take a week or more. See how it goes, use your own judgment and also ask the surgeon.
