You might want to look at some of our products to help the mouth area. DERMA-IONX which is an oral homeopathic product stimulates the enzyme systems in the body which reduces inflammation, promotes healing of the skin and helps with assimilation of nutritional components in diet and supplements. The supplements I use along with it include probiotics and Omega 3,6,9. Together with DERMA-IONX it produces a synergistic effect for a faster response. I would also suggest that you give only filtered water for drinking if your water contains chlorine or fluoride. For the dietary modifications you might want to try a grain free diet for a while. If more support than this is needed let me know because there are a couple more supplements that I might use depending upon the response you have gotten from the above.
Please feel free to contact us again if you have any other questions.
