I have a canker sore & have tried applying baking soda paste (baking soda & water) onto the ulcer and it immediately starts bleeding. is this bad?

Ulcer canker sore: For an open wound the ulcer might become more sore with your paste and open and bleed. You can apply a drying med, over the counter, Camphophenique to it twice a day and it dries up the sore slightly faster than natural healing.

Mouth Ulcers: The lesions will heal on their own in about a week. You're not going to get them to heal any faster by placing any medication on them.
