The Canker Spanker is the best thing I've found in years

[Bea]

I started using The Canker Spanker a few months back after my brother recommended it to me, for canker sores or mouth ulcers (I'm not sure which is the correct term). This stuff is amazing, but I can't find it in stores, only online and my dentist has never heard of it. Why isn't it more widely known when it's honestly the best products I've found for cankers?
