During my dental hygiene education, 17 years ago, we were taught that cavities were caused by a high sugar diet and poor dental hygiene. With this in mind, I was shocked when my 3 year old daughter got cavities in all of her upper primary molars. What we know now is that dental caries is caused by a contagious bacterial infection. Some mouths are more prone to infection than others. Some mouths have a lower pH than others. Some people have deeper groves or weaker enamel, making them more prone to decay. The Carifree products are amazing. They taste great and raise the pH in the mouth, which will naturally kill the bacteria that causes decay. I am especially excited that the gel will soon be available with fluoride. This will strengthen the enamel as well as raise the pH, all in a great tasting flavor that my daughter loves! Well done!
