Quantum Health Canker Cover Canker Sore Patches protects the sore from irritants like food, drink or braces. Just one patch will treat most canker sores. The tablet-like patches are made from edible ingredients and will stick to any canker sore within seconds where it will form a clear, gel patch that protects for 8 to 12 hours. Canker Cover delivers immediate pain relief and won't come off while eating.

Drug Facts

Active ingredient Purpose
Menthol 2.5 mg Oral Pain Reliever


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


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, nursing or taking prescription drugs. Keep this and all drugs out of the reach of children.


(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. Some discomfort may occur during the first few minutes for a small number of users, but will quickly subside followed by hours of soothing relief. Within 30 minutes the tablet expands to a clear, gel-like patch that will cover the sore for 8-12 hours before dissolving. (Note: Dissolution of the patch depends on available moisture in the mouth.) 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 simultaneously 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.


Store in a cool, dry place

Canker Cover 4.7 5 2 3
Packaging Your package is not large enough to fit bilingual instructions. Consequently the directions are almost impossible to read. Either enlarge the package or decide on one language. June 30, 2013
The only thing that works! I've suffered from canker sores all my life and I've tried every product known to man. Canker Cover is the only thing that has ever worked for minimizing pain and actually reducing the severity and length of time the sore persists. I sometimes have 2 or 3 canker sores at once. Canker Cover has made my life much better because I suffer much less. January 23, 2013
