I'm treating my two year old's teeth with calc phos, calc fluor and silicea. I'm using 30x potency for the calc salts, and I just now noticed that the silicea says 30c. I ordered 30x but got 30c. Two questions...1. Is 30c okay? 2. We've been diluting 6 pellets (sucrose-based) in water and letting her drink the water throughout the day for the last two weeks. Should we take a break, or is it okay to keep doing this daily? I was thinking about doing it for another two weeks to see if the cell salts make an impact on her cavity. I'm asking about the break because I just found a site that said breaks should be taken while taking cell salts. Thanks!
