@lisalucier Because of all the toxic chemicals that are put into our everyday products It took forever to see where the problems were, what might have been the problem and what actually was a problem. I found that my toothpaste was made with chemicals that I did not want to keep putting into my body. I tried different toothpastes the ones that were advertised as organic. Finally I started brushing with soda, and rinsing with peroxide diluted not full strength, 10% peroxide and the rest water.
