I am very familiar with this story. I shudder to think about making my kids brush their teeth every day with fluoride toothpaste. Luckily, they grew up on well water. The dentist would paint sealants on my kids’ molars, right after a flouride treatment. I remember the regional dentist at the time would come out to the elementary schools and seal kids teeth. I really don’t think he thought it was anything but a valiant effort to save these candy eaters from themselves😂! Nonetheless, it happened over and over again.
