Uncover the Secrets: How Long Does Dental Numbness Linger?
Dental numbness , or local anesthesia, is a temporary loss of sensation in a specific area of the mouth, usually administered by a dentist during dental procedures. It is achieved through the injection of an anesthetic agent, which blocks nerve signals in the targeted area and prevents the transmission of pain impulses to the brain. The duration of dental numbness can vary depending on the type and concentration of anesthetic used, as well as individual factors such as metabolism and blood flow. Generally, the numbness will start to wear off within a few hours, but it can sometimes last for several hours or even days in some cases.
