Dentists use a variety of methods to numb the mouth before performing dental procedures. One common method is to inject a local anesthetic into the gum tissue. However, there are some cases where a dentist may need to numb the mouth without using a shot. This can be done using a topical anesthetic, which is applied directly to the gum tissue.
Topical anesthetics work by blocking the nerves that transmit pain signals to the brain. They are less effective than injectable anesthetics, but they can be used to numb small areas of the mouth. Topical anesthetics are often used for minor procedures, such as cleaning teeth or filling cavities. They can also be used to numb the mouth before giving an injection of local anesthetic.
