Dental anesthesia - Definition

Ask a question


Dental anesthesia consists of numbing the part of the gums or the tooth that the dentist is going to operate on. It is a local anesthetic that often begins by applying some drops of the anesthetic on a small area of the mouth. This area then receives, without pain, a more powerful injection of anesthetic. Dental anesthesia allows dental surgery to be performed by blocking the ends of the nerves for a very short time. Several anesthetics can be used, certain ones in combination with others.
