Topical anesthesia is a type of local anesthetic applied directly to the skin or mucous membranes to temporarily numb a specific area.
It works by blocking nerve signals in the surface tissues, reducing pain, itchiness, or discomfort during minor procedures or examinations. Commonly used in dentistry, dermatology, and minor surgical settings, it comes in forms like gels, creams, sprays, or patches. Unlike injectable anesthetics, topical anesthesia does not penetrate deeply and is ideal for superficial treatments such as wound cleaning, injections, or laser therapy.
