Novocaine, a local anesthetic, is commonly used in dentistry to numb the area around the tooth being worked on. The duration of novocaine's effects can vary depending on the individual and the amount of novocaine used.
Typically, novocaine's numbing effects will last for 1 to 2 hours. However, in some cases, the effects may last for a shorter or longer period of time. Factors that can affect the duration of novocaine's effects include the individual's metabolism, the location of the injection, and the amount of novocaine used.
