Gelclair Sachets Gelclair provides pain relief to soothe mouth lesions, including those caused by medication, disease, radiotherapy, chemotherapy, oral surgery, traumatic ulcers caused by dental braces & dentures, & ageing. Gelclair works by coating the surfaces of your mouth to form a protective barrier, shielding exposed or sensitised nerve endings, thus making it less painful for you to eat & drink & can make your mouth feel more comfortable. Unlike preparations with an alcohol or anaesthetic base, Gelclair does numb or sting the mouth. It is supplied as a concentrated gel for dilution, to be used as a mouthrinse.
