Use Denttabs now for 18 months, the greatest advantage over normal toothpaste: the canker sores on the oral mucosa have been reduced to zero, before I had min. every 2 months a painful mouth ulcer in the mouth, or if I have bitten to the mucosa, this site has ignited immediately. That is now history. The reason: in normal toothpaste are frother that makes the oral mucosa permeable to bacteria. However, it has also used the Dentals 9 months, until this state arrived. Smooth teeth come added. and for all Flurid opponents: they exist now without Flurid.
