Hi after a bit of advice....my nearly 14yr old son has just been told by the dentist that he has some decay in one of his bottom teeth which needs a filling as its an adult tooth. My son has no pain in the area and I do not want him to have a amalgam filling. I would rather pay privately to have a white filling but was wondering if there is any advice on safe fillings or anything else I can get him to do naturally? A friend told me about oil pulling? I have never heard of this but would appreciate any advice. Thank you
