Our tablets are tested by the Academic Center for Dentistry Amsterdam (ACTA). They have determined that the amount of fluoride released is equal to or more than the amount in 'regular' toothpaste. We use the optimal 1450 parts per million fluoride.
The effect of fluoride is further enhanced by the innovative hydroxyapatite. This protects just like fluoride, but is tooth-related material. In addition, it closes the 'dental tubules' (small channels) to your nerves, so that there is less chance of sensitive teeth. It also has a whitening effect.
OPTIMAL RDA VALUE
Abrasives are used in toothpastes to remove plaque and stain buildup. Smyle has an RDA (relative dentin abrasivity) of 100 – 115.
All values below 250 are considered safe for a lifetime of use, according to the international standard of the American Dental Association (ADA).
An RDA value of 100 – 115 is very safe and is comparable to that of a medium toothpaste / bottom of a whitening toothpaste.
