Yes. If your drinking water has more than 0.7 parts per million of fluoride, you may not need a fluoride rinse. If your gums are irritated or if you have gum disease, a fluoride rinse may make things worse. Ask your dentist or doctor if this applies to you. Since fluoride rinse is a prescription product, the dentist or doctor will need to write a prescription for you. Never let your child use a fluoride rinse that has not been prescribed by the child's dentist or doctor. Lastly, if a fluoride rinse seems to cause changes in your gums or teeth, tell your doctor or dentist.
