I have had a couple of ulcers and soreness in my gums/ teeth. But I believe the teeth/gum thing is from holding the e-cig in my teeth. (Analogs we held with our lips, but these we have to bite to hold) It's gotten better since I pay attention to what I'm doing.
Peroxyl is another great product (mouthwash) for the ulcers.
