Yes, Benzocaine can be used to temporarily relieve pain from oral ulcers by numbing the affected area, making eating, drinking, and speaking more comfortable. Products like gels or ointments containing Benzocaine are meant for short-term use only. They may not treat the underlying cause of the ulcer. It should be applied as directed, avoiding swallowing, and use should be limited, especially in children or people with certain blood conditions. If ulcers persist for more than one to two weeks, are very painful, or keep recurring, it is important to consult a dentist or doctor for proper evaluation and treatment.
