In brief: Depends

Depend on the type of Lidocaine the dentist uses.
Usually lasts 2-3 hrs. A healthy person will not get dehydrated in 24 hrs, but usually you do not have to refrain from eating for that long.

In brief: You can drink

You certainly can and should eat and drink after wisdom teeth removal.
You should not rinse, spit, or drink through a straw during the first 24 hours but you should be encouraged to drink fluids normally with a glass. You also can eat after the bleeding has stopped. Just avoid hot foods and try to avoid chewing directly over the surgical sites.

In brief: No dehydration

Typically, you are numb from the Lidocaine for about 8 hours after your extractions.
If you were sedated with an IV during the procedure, you received fluids via the IV and you should not be dehydrated.

In brief: About 2 hours...

You should feel the effects of Lidocaine for about 2 hours after it was administrated.
You are allowed to drink water on the opposite side or by gently sipping. You do not want to rinse the socket area out or rinse at all for several days. The idea is not to harm or rinse out the clotting that is now taking place. This is a crucial period.

In brief: Depends

The length of time anesthesia lasts depends on several factors to include your metabolism, type of injection given, the amount of Epinephrine that was in the lidocaine.
An average time would be about 2 hours. Not eating or drinking 24 hours before surgery may cause problems with dehydration unless you plan to have intravenous sedation.
