Another study demonstrating that an “inevitable” conditions such as dental cavities may actually be preventable and, at least in its early forms, even treatable by vitamin D. The study immersed extracted teeth in different types of saliva with varying pH levels. One of the saliva types also came from volunteers that had been taking a (paltry) dose of 1,000 IU vitamin D3 daily for six weeks, before the saliva was collected. The tooth immersion was just 12 hours, and that was sufficient to significantly increase the re-mineralization of the teeth immersed in the saliva from people who had taken the vitamin D. Considering the puny dose of vitamin D used, and the fact that it was also oral route, these robust results suggest that a more targeted application of vitamin D – i.e. directly into the cavity, on the gums, or sublingual – may achieve much stronger effects, potentially even for severe dental cavities. Combining vitamin D with vitamin K may have an even stronger effect, due to the synergy of those vitamins in regards to osteocalcin synthesis/release and bone/calcium metabolism.
“…For all specimens, there was a significant decrease in both (Ca and P weight %) after demineralization and then they significantly increased after receiving vitamin D3. The microhardness and elemental analysis provide confirmed results that were represented as a statistically significant difference at (P≤ 0.05) between groups that received vitamin D3 and those without vitamin D3 dosage. Oral vitamin D3 has a significant potential in motivating remineralization of early lesions on the enamel surfaces representing improved surface microhardness and minerals content (Ca and P weight %) of demineralized tooth surfaces.”
