Silver Nitrate Caustic Wooden Sticks 6" Long Applicator Individual Use Sticks (30)

I like to call this the 'nuclear option' when tackling stubborn canker sores. Once you get over the bitter taste and the chemical burn, it isn't so bad, and boy, does it work. It basically burns your canker sore away and cauterizes it to prevent the infection from spreading. I only wish they sold these in drug stores.

All good, they work.

Works great stopping bleeding.

got rid of the finger warts. They took a couple applications because of their sizes.

this product helped with pain and healing of a mouth ulcer. User beware, however, this can stain your teeth if it touches the teeth before the product dries. I tried everything and had to get my dentist to buff off the stain.
