Can local anesthesia make you sleepy?

I am a 24 year old female. I had a dental procedure under local anesthesia today and after it I become very sleepy. Can local anesthesia make you sleepy?

Many a times, you get intravenous sedation as well. Quantitatively, you should not.
Yes.. a side effect.
No. Unless you are given medication to make you sleepy
No
Local injection can indeed change one's sensorium, especially if a considerable dose was injected. A normal, healthy person should metabolize this local anesthetic in a few hours.
Typically, local anesthesia should not make you sleepy. In some dental cases, they may provide sedation, however that should have been explained to you and you would have to be driven home from the appointment. If local anesthetic was given alone, you typically would not see this reaction.
No, local does not make you sleepy. If you had something in addition, like Valium, that can.

Yes, but it depends on how much local was injected. Lidocaine a local anesthetic was tried as a general anesthetic a long, long time ago, but it depresses the heart muscle in large doses and hence never used as such. Lidocaine with epinephrine is absorbed slowly and hence less chance of sleepiness. Most of the time, it’s used with epinephrine to prolong local anesthetic effect.
