Is toothpaste without fluoride bad or useless?

Fluoride is good!: Fluoride is a tried and true way of preventing cavities. I recommend Fluoride toothpastes for those who are old enough to spit and up. Xylitol, also a natural ingredient, is a plant-based sugar-alcohol that has recently been added to toothpastes. Studies show it too can reduce chances of cavities. Diet, still, is the #1 way to prevent cavities. Brushing twice daily also is necessary.

Neither: Non-fluoridated toothpaste is neither bad nor useless. But, it is not as effective at preventing tooth decay as toothpaste with fluoride.

Less effective: The mechanical action of toothbrushing will remove food debris and plaque but the Fluoride remineralizes damaged enamel and may inhibit bacterial metabolism and prevent tooth decay.

Fluoride is not bad: Fluoride at low dose is not problematic and has basically eliminated large amounts of decay.
