Well I'll share my experience. I had my only filling come out, by back left molar, it went all the way down to the root...very painful. I refuse to visit doctors or dentists. its been 4 months from that time and its the tooth has half way filled in. Whats makes it bad for salt and excessive protein (SAD has way to much for me) What has been the life saver....honestly RAW beef kidney fat...honest. Doesn't taste bad either. I eat it everyday this is only one problem, I'm extremely severe Crohns Disease. Teeth can heal...that's what I believe anyway. NO PAIN anymore ever.
Let me if you have other questions...but you don't have to go back to the dentist, it can heal with proper nutrition.
