Dentacain Gel is used to relieve pain and irritation associated with mouth ulcers and sore gums. It contains Choline Salicylate, an anti-inflammatory ingredient that helps reduce pain, redness and swelling, combined with Lidocaine, a local anaesthetic that works by numbing the affected area and blocking pain signals. Together, these ingredients help ease the burning sensation and discomfort associated with mouth ulcers. This gel should be applied directly to the affected area inside the mouth with clean hands, as directed by the doctor, avoiding eating or drinking immediately after application.
