how long does it take for local anesthetic (numbing stuff)to ware off??
Locals don't normally take but several hrs to wear off, depending on how much they had to use to get you numb. If your talking having a tooth filled and they only had to give I carpule (I injection) your looking at prob 3-5 hrs. (=
Appox. 3-5 hours for any local that's injected into your body. Whether it's removal of a cyst all the way to a tooth with novacaine.
Thankzzz :D
