Most local anesthetics are mixed with adrenaline or epinephrine. These substances make the anesthetic last longer and help keep you out of pain. However, it can also make your heart race. This is usually prevented by not injecting the anesthetic into a blood vessel. But even with a careful dentist, it can still sometimes happen. If this happens to you, rest assured your racing heart will subdue after a minute or so. If you have heart problems, your dentist may use a local anesthetic that does not contain epinephrine.
An anesthetic that does not carry epinephrine may require multiple injections because it does not last very long. The feeling of having your mouth numb is often described as asleep, full, or tingling. Depending on the treatment area, you may also feel numbness in your tongue, chin, cheeks, the roof of your mouth, nose, and just below your eye.
The length of time a local anesthetic takes to wear off will vary based on which type was used. Generally speaking, your treated tooth will be numb for hours, and your lips and tongue will be numb for hours from the time of injection. The numb feeling goes away as the blood flow carries it away from the injection site to be broken down or metabolized.
You may also ask your dentist to use OraVerse after your treatment. OraVerse is an injection that reverses the effects of the anesthetic, making the numbing sensation go away twice as fast.

A doctor or nurse will usually give you a prescription for the lidocaine cream or the cream itself ahead of your appointment. Always follow the instructions that come with your cream. If you're having a drip fitted or having blood taken, put the lidocaine cream on 1 hour beforehand. For minor surgery, your doctor may tell you to use the cream more than 1 hour before the procedure.

If you're having a cosmetic procedure and have bought lidocaine from a pharmacy to numb the area, tell the person doing the procedure before it starts.

Do not use the cream on your eyes, ears, nose or the inside of your mouth, or on your genitals or bottom anus — unless your doctor tells you to. If you forget to use the cream, or you put it on less than 1 hour beforehand, tell the person who is going to do the procedure. They may want to delay it. Using more than the recommended amount can cause side effects.
