That is a myth that has been disproven by many. Studies have shown more
of the opposite is true. Some suggest it increases bone development.
Possibly but other studies have shown any increased development is in
the form of weaker overall bone structure. It is a subject of debate still.

However, the studies I believe you refer to are known as sodium fluoride
,calcium citrate and vitamin D therapy. They have largly been proven to
cause more harm than good. This is also not the same as the waste
byproduct form of fluoride found in drinking water.
