When I was growing up in Vancouver (my hometown), fluoride had been removed from the water source. This had caused many dental problems for individuals who also see dentists who do not use fluoride washes. Apple, avocado, banana, cherries, peaches, strawberries, and cantaloupe have fluoride levels that are low, but also adequate enough to keep teeth healthy. Carrots, celery, tomatoes, cucumber, and radishes also have fluoride in them. Eggs and milk also contain small amounts of fluoride.
Now, fluoride has 2 sides to the coin. On the one hand, it is essential for mineralization of bones and teeth. It also plays an important role in preventing cavities. The other side of the coin is that too much fluoride can cause fluorosis, which is damaging to the teeth and bones and can make them weak.
However, getting too much fluoride is not common in the US unless someone is ingesting toothpaste, drinking water with high concentrated levels, or consume too much in supplement form.
8 ppm is considered high for fluoride, however, strawberries only have 0.02 ppm per serving!
