The thyroid gland uses Iodine to make thyroid hormone. We know the thyroid gland appeared in evolution at the same time as back bones (vertebrates). Radioactive Iodine injected into patients shows a full outline of the bones on a total body scan. This means one of the places Iodine goes to immediately is bones. Thyroid hormone makes bones grow, mature and remodel, when necessary. Together thyroid hormone, iodine and growth hormone maintain a healthy bone structure. As vertebrates (animals with backbones) are the only animals with thyroid glands it makes sense that iodine and thyroid control bone structure and function.(6-8)

So even though fluoridation might work in children it does not work in adults. Therefore adults using fluorinated tooth paste will unlikely see any benefit and may end up with signs of excess fluoride such as browning of the teeth. It does not make sense to substitute a toxin for the natural iodine that should be there. It would have been simpler and more effective if the iodine intake of children was raised. This would provide the needed iodine and make stronger thyroid glands.

teeth are bones... replace fluoride with iodine and fire your dentist.
