Recent findings indicate that the bacteria that causes cavities can now fend off fluoride

Scientists don't know how bacteria is doing this, but when they do we'll offer a new means to create an oral health regimen that is more bacteria-hostile. But wait! Don't abandon fluoride! It's still your best defense against plaque buildup and cavities, along with brushing at least twice a day, flossing once a day and getting regular professional cleanings from your dentist.
