Life Long Smiles uses an all natural paste which is a safe alternative to traditional fluoride, is non toxic and helps to remineralize the teeth. This product has an alkalizing effect which helps to balance the pH of unhealthy acid in the mouth. The taste of the paste is a good indication of your dental health. If you notice a bitter/unpleasant taste, this means your mouth is on the acidic spectrum. After a thorough cleaning with Registered Dental Hygienist Melissa, you will notice that the taste of the paste suddenly tastes good and fresh which means the paste has balanced your pH levels in your mouth. Melissa takes on an integrative holistic approach using natural organic therapies in combination with conventional treatment where possible.
