Canker Cover adheres to any mouth ulcer and becomes a clear, gel-like patch. One patch fully treats most sores.

Uses: For the relief of pain associated with canker sores or minor irritation or injury of the mouth and gums.

Suggested Use

(Adults & children 5 years of age and older) Place the Canker Cover Patch on a clean, dry finger with the white side up. The sore should be dry (pat with tissue, if possible). Place the white side of the tablet on the sore and hold in place for 20 seconds. If sore is difficult to reach (in the fold between the cheek and gum or near the teeth or lip) break the patch along the score and use half. Some discomfort may occur during the first few minutes, but will quickly subside, followed by hours of soothing relief. Within 30 minutes the tablet expands to a clear, gel-like patch that seals and protects the sore for 8-12 hours before dissolving. Do not remove patch before it dissolves. In case of discomfort, the patch may be removed by gently peeling the tablet from the sides while washing with warm water. Avoid the use of any instrument to remove the patch. If needed, apply a second patch 24 hours after the first application. In most cases, just one patch is needed.

Other Ingredients

No sugar, glucose, gluten, lactose or preservatives. Less than 1 calorie.


Canker Cover should not be used on children under 5 years old without consulting a physician. If sore mouth symptoms do not improve in 7 days; if irritation, pain or redness worsens; or if swelling, rash or fever develops, see your doctor or dentist. Consult your physician if you are pregnant, breastfeeding or taking prescription drugs. Keep this and all drugs out of the reach of children.

Store in a cool, dry place.
