Fluoride Bioavailability in Your Toothpaste – Baby Dental
The longer your toothpaste sits on the shelf after it is manufactured, the more time there is for fluoride to combine with ingredients in your toothpaste like abrasives, sodium lauryl sulfate (SLS), etc., which reduce the overall fluoride content and effectiveness of your toothpaste. Studies have shown that this reduction in fluoride availability can occur rapidly over the first few months after toothpaste is manufactured. This happens even before your toothpaste reaches its expiration date.
