The numbing needle used by dentists is a small, thin needle that injects a local anesthetic into the gums or other tissues in the mouth. The anesthetic numbs the area, preventing pain during dental procedures.
The numbing needle is an important tool for dentists, as it allows them to perform procedures without causing discomfort to the patient. In the past, dental procedures were often painful, but the numbing needle has made it possible to have relatively pain-free dental care.
