Good morning, what are you lovely ladies views on fluoride treatments @ the hygienist. Once a yr he paints on a gel on my teeth, after cleaning them, which helps tremendously for sensitivity etc, my children have been having this treatment for many yrs and have wonderfully strong teeth. My hubby nearly had a fit and insists that it is toxic, which of course it is, but the hygienist insists that it is safe.....do I stop rather?
