A numbing shot, also known as a local anesthetic, is a medication injected near a nerve to block pain signals from reaching the brain. It is commonly used in dentistry to numb a specific area of the mouth before a procedure, such as a filling or extraction.
Numbing shots are generally very effective in preventing pain during dental procedures. However, the injection itself can cause a brief stinging or burning sensation. This discomfort usually lasts only a few seconds and is typically well-tolerated. In some cases, a topical anesthetic may be applied to the injection site before the numbing shot is given to further reduce any discomfort.
