How Novocaine Works
Novocaine comes in both gel and liquid forms. The gel form is used as a topical anesthetic to make injections more comfortable, and the liquid form is injected into the tissues to achieve local anesthesia. The injection is done very gently with a syringe.
Novocaine works by stopping the transmission of nerve impulses from the area being treated to the brain. It acts like a temporary roadblock, preventing any nerve impulses from getting through so that your treatment can be performed without you feeling anything.
Although extremely safe, novocaine should not be used in some instances. Before beginning treatment, your dentist will review your medical health questionnaire to determine any potential risks. If you are allergic to certain substances, have a history of problems with local anesthesia or are pregnant, they will work with you to form the best treatment plan.
