Hydroxyapatite is a naturally occurring mineral that makes up most of the tooth enamel and bone. It offers an alternative approach to dental care by helping to remineralize and strengthen teeth without the use of fluoride. This makes it an excellent choice for those seeking effective, natural alternatives for oral health. While there's nothing wrong with using fluoride in safe amounts (if that's your preference), we at Pop Bright prefer to embrace eco-friendly practices. Thus we've chosen hydroxyapatite as our key ingredient for a natural and effective approach to oral health.
