(Adults and 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 the sore is diffcult to reach (e.g. if it is in the fold between the cheek and gums, near the teeth, or near the tip), break the Canker Cover in half along the scored line, 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 into 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. Store in a cool, dry place.
