Great, that's the key. If you're seeing improvement I wouldn't worry. I also wouldn't take the Heliomolar thing to heart quite just yet. Your body will let you know if there's a problem.
And as to the claim of Heliomolar being cheap? I'm not so sure I buy that either. Could be, but when a Holistic Dentist who's been practicing Hg free dentistry for 20+ years, and who is more up to date on all these issues than me says that's what he would put in his mouth, that rings louder to me than some random web site's opinion.
Take it easy marn and let us know your progress.
