Typically anesthesia wears off within an hour
If it's a top tooth, then 2-3 hours is the norm, but it can last 3-4 hours. On the bottom it usually lasts longer. Sometimes 4-5 hours or even 6-7 hours. I have had very few patients who told me the numbness lasted as long as 9 or 10 hours.
Could last for 4-6 hours for it to completely dissipate
Depends on the type is anesthetic used, but usually within a few hours you should be back to normal.
Depends on the type of anaesthetic given. Can be a couple hours to almost a day.
Usually between 1-3 hours.
How long anesthesia lasts is patient dependent. People metabolize anesthetic, and really all medications, differently. In addition, the length of anesthesia is also dependent on they type of anesthetic being used. A general guideline is 2-4 hours. If you exercise after rx, assuming you are not having surgery, this will help the anesthetic wear off more rapidly.

It depends on what anesthesia is used. Dental anesthetics usually lasts about 2-6 hours
Hello,
Before the filling procedures starts the doctor will administer local anesthesia (local to the tooth being filled). The amount of time the anesthesia lasts relates to two different variables. First, there are several different types of anesthesia and they are used for different things. For example, most people refer to local anesthesia as novacaine. Novacaine is still around but does not get used nearly that much. In fact, Lidocaine gets used the majority of the time. Lidocaine usually wears off in about 1-2 hours from the time it was given. However, there are local anesthesia medications that will last up to 8 hours.
The second factor to consider is the metabolism of the person receiving the local anesthesia. Sometimes people can metabolize anesthesia very quickly. Lidocaine which usually takes 1-2 hours can be metabolized and gone by someone inside of 20 minutes! So local anesthesia can be very personal as well.
Fun fact: Did you ever wonder why it is spelt: cocaine? Yes, cocaine is and is used as a local anesthesia as well!
Hope this helps.
My best to you!
