Hi Kevin:
I emailed (and ordered) FG6x from ABC homeopathy online. I asked them a few questions and they were very helpful. I had no problems with enamel damage but I didn’t use it long-term, just a few weeks in order to loosen plaque. You might email them with these questions.
Like Anon said, there’s no substitute for a good dental done by a vet, but if health problems prevent such things sometimes we have to do our best without. Once the plaque started chipping off my dogs teeth, I used coconut oil (as a toothpaste) for its antibacterial properties. I do think it helped my dog feel better!
Cheers =)
