Question

Quizplus · Accepted Answer

Topical anesthetic agents, such as benzocaine or lidocaine, provide a temporary numbing effect on the surface of the oral mucosa when applied topically. This can help to reduce discomfort during dental procedures or to temporarily relieve pain from mouth sores or injuries. Local anesthetics are injected into the tissues to provide deeper numbness, while nitrous oxide/oxygen is a gas used for mild sedation and relaxation. Analgesic agents are pain relievers but do not provide numbing effects on the mucosa.
