Local anesthesia is a common technique used in dentistry to numb a specific area of the mouth. It is typically administered through an injection directly into the gums or inner cheek. This form of anesthesia allows dentists to perform various procedures, such as fillings, extractions, and root canals, with minimal pain or discomfort for the patient.

Local anesthesia works by temporarily blocking the nerves in the targeted area, preventing them from transmitting pain signals to the brain. This allows the dentist to work on the teeth or gums without the patient feeling any pain. While the patient may still feel pressure and movement during the procedure, they should not experience any discomfort.
