Molasses comes from Sugar cane and has Sugar in it. That would be a source of tooth decay.
Not black strap molasses beside no one suggested swishing with it! I can see a lot of people realy dont understand how the black strap mollasses and the acv drink works! Something as critical as the job bsm does in helping absorb minerals and helping build strong bones and teeth should know what they are talking about before they denounce it!
