I tried it for a month or so and didn't really notice too much. I would breath out in fresh air though and some pain would be on my lower front teeth! I stopped it and that mainly went away shortly after. It is almost as if it did something to enamel or similar to a cavity.


You need to do it for 2-3 months minimum. It works slowly, and it can increase some symptoms in the first month. You stopped short of the effect, so don't blame the method.
