Why dentist tells me not to eat until the anesthetic wears off?

I was given a local anesthetic in my lower jaw and my dentist tells me not to eat until the qnesthetic wears off, not because of my teeth but because of my tounge. Why is the dentist giving me this advice?

Why dentist tells me not to eat until the anesthetic wears off?
Your dentist tells you this because when working on mandibular (lower) teeth the dentist must give you an inferior alveolar nerve block. If the block is done correctly you will have profound anesthesia in the teeth, the cheek, the lip as well as the tongue on the side that the block was given. If you eat before the anesthesia wears off you can potentially bite you tongue, lip and cheek really badly and not realize it as they will still be anesthetized (numb).
Reply:Because you might bite your tongue or your cheek while numb.
Reply:I agree with the previous answer. Or you might choke on your food or not chew it well enough.
Reply:You can't feel your tongue so there's a good chance you could bite a chunk out of it.
Reply:The anesthetic desensitizes you to pain, so you will not feel it when you bite your tongue and you could really do a lot of damage to your tongue or side of your mouth by mistaking it for the food.
Reply:Because you can mistake your tongue for a piece of food, seriously injuring yourself and not even feeling it at that moment. But suffering when the numbness goes away, because there is nothing your dentist can do for you if you bite your tongue, cheek, or lip. If you are hungry get a milkshake or a smoothie, it will make you feel full.
Reply:1. you could bite your tongue or side of your cheek


2. you can't sense temperature so if something is too hot you might not know
Reply:You could bite yourself and not know you are chewing on your own tongue.


And


It is hard to maneuver your tongue properly and that increases the chances of choking.
