If you check out Ramiel Nagel on his website curetoothdecay.com, he has a lot of great information on there. Also as @gardenofeden mentions: oil pulling helps to keep teeth and body healthy. There are a lot of detoxes but you need to research properly because some may make things worse. Diet of course is very important too. I can totally forget about my kids getting into oil pulling, but I can control what they eat and drink, so that's what I do to prevent tooth decay. Tony at HerbsPlusBeadWorks on YouTube has a video about regenerating teeth, he has a lot of other info that is great too. I hope this helps.
