Fluoride really does make teeth stronger and more resistant to cavities. It works in two ways. One way is by swallowing Fluoride – that’s why a small amount is often added to city drinking water. The other way – which is the more important way – is by fluoride touching the teeth without swallowing it. This is how toothpaste and the fluoride we use at the office work.
It is definitely possible to swallow too much fluoride, so please talk to Dr. Thom about what fluoride use is appropriate for your child.
