Over-the-Counter Fluoride Rinse
Over-the-counter fluoride rinse pro- vides a lower concentration of sodium fluoride than toothpaste or varnish. The concentration is most commonly 230 ppm (0.05% sodium fluoride). Ex- pert panels on this topic have con- cluded that over-the-counter fluoride rinses should not be recommended for children younger than 6 years because of their limited ability to rinse and spit and the risk of swallowing higher-than- recommended levels of fluoride.
