Canker Cover The Oral Canker Sore Patch

Canker Cover is a tablet-like patch made from edible ingredients. It sticks to any canker sore within seconds, and then forms a clear, gel patch that lasts 8 - 12 hours. The patch protects the sore from irritants - food, drink, braces, etc., and releases healing nutrients. A single patch will treat most canker sores.
