I emailed Walter Clifford with the materials that were used in my mouth and although they contain aluminium and fluoride, he says they are perfectly safe and the company that made it were very good.
When i went back to my dentist complaining about the materials used he just said i was the first person to complain.
Bex, i know what your going through cos im the same, i spend most of my time trying to find answers on the internet, its my life now. I have become so tired lately, this is unusual for me, i normally suffer with insomnia. I wonder if it is cavitations or mercury causing this.
