Local Anesthetics

Local anesthetics are medications used to temporarily numb a specific area of the body to prevent pain during minor surgical procedures or medical examinations. They work by blocking nerve signals in the area where they are applied or injected, which stops the brain from receiving pain sensations. Common examples include lidocaine and bupivacaine. Local anesthetics are generally safe and allow patients to remain awake and alert while reducing discomfort, making them essential tools in both dentistry and various medical practices. They differ from general anesthetics, which induce a state of unconsciousness.
