Dental injections are a common part of cavity fillings. They are used to numb the area around the cavity so that the dentist can work without causing pain. The injection is typically given in the gum tissue near the cavity. The dentist will use a very fine needle to inject a small amount of anesthetic. The anesthetic will take effect within a few minutes and will last for about an hour.
There are several benefits to using dental injections for cavity fillings. First, they can help to make the procedure more comfortable for the patient. Second, they can help to prevent the patient from moving during the procedure, which can make it difficult for the dentist to do their job. Third, injections can help to reduce the risk of infection.
