Many over 50 people who think they have periodontal disease actually have fluorosis from a lifetime of ingesting industrial factory sodium-flouride waste in their drinking water. It makes the teeth brittle, subject to cracking and these tiny cracks invite infection and bacteria.
I suddenly had multiple cavities and 2 cracked teeth which totally baffled my dentist. In a few months, more cavities and 2 more cracked teeth. I went to an oral surgeon who was equally baffled. I switched to bottled water which was flouride free, switched to xylitol toothpaste and mouthwash, and it suddenly stopped. No more cracked teeth, zero cavities. I also no longer go to that dentist or oral surgeon who both swear by flouride. I have also become a member of FlourideWatch.
