GUM Canker-X gel is an aloe Vera based formulation that helps treat canker sores (also known as aphthous ulcers), mouth sores, and minor cuts or abrasions by providing a protective healing barrier. The patented triple action gel offers fast pain-relief and helps soothe the affected area without stinging or burning on application. GUM Canker-X gel is a non-prescription product without benzocaine or alcohol. Mouth ulcers are not generally a significant risk to your oral health. However, if you have severe and frequently recurring mouth sores or if they do not heal within 10 days, consult your dentist or physician.
