Takes around 1.5 or 2 hours.

Typically, oral or IV sedation is used along with local anesthesia. Most wear off rather quickly, but we generally ask that patients not drive after the procedure due to sedative effects. You many experience some sleepiness for a couple of hours after the procedure, but at the most 4-6 hours after the procedure all the effects should be out of your system if you are otherwise in good health.

Depends on the drug. Can be a few minutes to 24-36 hrs

There are a number of factors which influence the endpoint for sedation. Choice of sedative medication is the most obvious, along with the dosage used. In general, anesthesiologists recommend that you do not drive or perform other complex tasks or make decisions for 24 hours. You may seem quite lucid shortly after the procedure but sedation often influences higher cognitive centers used in decision making and judgment. If you have specific concerns, ask your oral surgeon and/or anesthesia provider for further guidance. Good luck!
