Will I loose the benefits of fluoride in my drinking water if I install a home treatment device or drink bottled water?
Certain types of home treatment devices will remove 85 to more than 95 of all the minerals in water, including fluoride. These are reverse osmosis, distillation units, and deionization units (not water softeners – they leave fluoride in the water.) If you use one of these types of devices, consult with your dentist about fluoride and possibly your doctor about iodine supplements. The situation with bottled water is less clear. One recent study at the University of Texas’ Dental Branch in Houston showed many bottled waters contained very little fluoride, although a few contained adequate amounts. Unfortunately, even in those products, the fluoride level dropped to about 25 to 50 percent of the original value over a two-year sampling period, without a change in product name or label. If you are drinking bottled water, most likely you are not getting much fluoride. Remember if you are using bottled water to make formula for your baby, be sure to talk to your doctor about using fluoride su
