Dental needles are used to administer local anesthesia during dental procedures. They come in a variety of sizes, with the larger bore needles being used for injections that require a greater volume of anesthetic. The size of the needle is determined by the type of procedure being performed and the amount of anesthetic that is needed.
Larger bore needles are typically used for injections that are made into the bone, such as when a tooth is being extracted. They are also used for injections that are made into the palate or the back of the throat. Smaller bore needles are used for injections that are made into the gums or the lips.
