1. Calcium and magnesium have to exist in the body in the correct ratio, or all kinds of imbalances can occur. And most people do not get enough magnesium. Best way to get it is Epsom salt baths, but this supplement is also a good way to increase your magnesium. OTC pill supplements for magnesium are generally not very absorbable by the body, so that's the last resort.
2. There is a DH preset for Sjögren's (DH_0383 Sjogren's Syndrome Correction and Balance) that might help, and I'd run the one for Dental pathogens as well. (DH_0012 Teeth & Gums Decay & Restoration). Along with the usual precursor Presets. And this might sound crazy, but I wonder if chewing gum would help to mechanically stimulate the salivary glands. (The kind with sugar, not the kind with artificial sweeteners, which can have a laxative effect.)
3. Consider using Spooky2 to convert Molecular weight (MW) to frequencies: calcium phosphate Ca3(PO4)2 or Ca3O8P2 and hydroxyapatite Ca5(PO4)3(OH) or Ca5HO13P3 Molecular Weight 502.3.
