Depends.: Novocaine has not been used in the us for many years. Newer, more effective local anesthetics have replaced it. Some last longer than others and where the injection is given matters as well. Lower teeth can stay numb longer. The amount given will also determine duration. In general, numbness will last from 30 minutes to up to 6-8 hours.

A 39-year-old female asked:

Can you have side affect from dentist novacaine?

2 doctor answers9 doctors weighed in
Dr. Richard Ruden
Dentistry 38 years experience
Yes: Many dental anesthetics are given via injection. If the needle punctures or nicks a vessel blood can seep and collect below the surface of the skin or the gum tissue. This can lead to swelling. Although painful, hematomas are not considered dangerous. Local anesthetics for dental procedures are designed to numb the nearby tissue. It takes time for these to wear off, you may experience parasthesia.

Why no local?: Why are you not having any local anesthesia? If you elect to not use a local anesthetic, you may feel anything from a minor discomfort to an intense burning sensation. Speak with your dentist before treatment to make sure you understand all your options. Modern dentistry is usually pain free.
