Balance of the two may not matter and additionally calcium intake may not be necessary?
Only in the presence of high glucose or a high sugar diet; calcium always opposes phosphorus in the presence of high blood glucose? (almost behaves as if it were magnetic)
calcium<===[high glucose/high sugar diet]===>phosphorus
phosphorus==>[low glucose/low sugar diet]<==calcium is absorbed back into the bones and teeth.

 “…In diabetic patients, an increase in salivary flow with unchanged salivary glucose concentration and glucose excretion rate were observed under the same experimental conditions. Salivary glucose concentration and excretion were much higher in diabetic patients than in control subjects, whether in unstimulated or stimulated saliva. No significant correlation between glycemia and either glucose concentration or glucose excretion rate was found in the diabetic patients, whether in unstimulated or stimulated saliva. …” …More
 Glucose estimation in the salivary secretion of diabetes mellitus patients
 Human salivary sugar clearance after sugar rinses and intake of foodstuffs.
 Besides the benefits of a low sugar diet i.e. keto, you can also REGENERATE tooth enamel and skip the dentist doing this:
DO NOT DRINK: swish (1/2 cup or less) and rinse (push solution through teeth & gums) for 5 minutes a day:
2 Teaspoons of Trisodium Phosphate (TSP), Fine Crystals, 99.9% Pure Food Grade (your choice?)
6 Teaspoons of Baking Soda (sodium bicarbonate)
To 16-24 oz. of filtered water, place in a bottle and shake thoroughly (everytime you use it) and store!
Note: Also tightens up loose teeth! Better at preventing cavities when they start to form!
RESULTS: you will notice cavities disappearing (depending on depth of decay) with doing this and may notice little black specs and other particle when you spit so don’t be alarmed!
Dentists will hate you!
 ”…Vitamin K is found in high concentrations in the salivary gland where it breaks up dental plaque.…More
 ”…The ability of vitamin K-related compounds to inhibit acid production in isolated saliva had no relationship to their vitamin activity, and the most effective of these compounds…” ”…Activator X (Vitamin K) also influences the composition of saliva. Price found that if he collected the saliva of individuals immune to dental caries and shook it with powdered bone or tooth meal, phosphorus would move from the saliva to the powder; by contrast, if he conducted the same procedure with the saliva of individuals susceptible to dental caries, the phosphorus would move in the opposite direction from the powder to the saliva. Administration of the Activator X concentrate to his patients consistently changed the chemical behavior of their saliva from phosphorus-accepting to phosphorus-donating… ”…Price used the combination of high-vitamin cod liver oil and high-Activator X butter oil as the cornerstone of his protocol for reversing dental caries. This protocol not only stopped the progression of tooth decay, but completely reversed it without the need for oral surgery by causing the dentin to grow and remineralize, sealing what were once active caries with a glassy finish. One 14-year-old girl completely healed 42 open cavities in 24 teeth by taking capsules of the high-vitamin cod liver oil and Activator X concentrate three times a day for seven months. …More
 ”…Saliva production is the exocrine function of the salivary glands. The buffering capacity of saliva is critical to neutralizing the oral environment. This minimizes the de-mineralization of enamel and enhances its re-mineralization. K2, such as that found in fermented cheese, improves salivary buffering through its influence on calcium and inorganic phosphates secreted. Data collected from several selected primitive cultures on the cusp of civilization demonstrated the difference in dental health due to diet. …More
