What Does Fluoride Do?

Dear Dr. Ellie, 

I have always wondered, what does fluoride do for the teeth? I know my densist gave me fluoride treatment as a kid, but never understood why. Can you help explain it for me?

Dear N,

Fluoride is a pretty powerful ally in the fight against tooth decay. It aids in the remineralization process, encouraging the minerals to heal the damage done to the teeth by the acids in the mouth. Also in this process of remineralization, the teeth actually become harder, and less prone to tooth decay.

Additionally, fluoride inhibits mouth bacterias ability to produce the dangerous acids that decay the teeth.

Fluoride is commonly found in tap water here in the States (although I have concerns about that) and in fluoride toothpastes and mouth rinses such as ACT. It is important to expose the teeth to fluoride a couple times a day (2-3), but be careful not to ingest too much of it, as this could cause serious problems.

I hope this answers your questions!

Best Regards,

Dr. Ellie Phillips

    I read a number of articles that said fluoride was initially used as a rat and insect poison!

    Fluoride is a very big subject with a dark and a bright side to the story. If you select information carefully, you can make a good or a bad case for fluoride! I stand right in the middle and say there are bad ways to use fluoride and also helpful ones. Years ago I met a publisher that would have been prepared to publish my book IF I had completely denounced fluoride and talked only about the bad pieces of the story. I would not consider doing this, since the truth about fluoride is (when used correctly and in correct dilution) – it will work with xylitol to reverse and repair cavities in teeth. This is a wonderful and healthy thing to do – since fillings have their own toxicity and potential problems. In my chapter on fluoride, I explain that in a perfect world, with no stress, no acid reflux, no mouth acidity and no aging – we would not need fluoride. We need fluoride to keep enamel strong, repair damaged teeth, prevent fillings and heal sensitivity. Fluoride acts as a catalyst – it works as a film to help minerals from saliva go into the tooth surface to strengthen the outer shell of the tooth.The result is that the tooth surface will be smoother, look brighter, and be more resistant to acidic attack in the future. Personally I have concerns about the potential toxicity and detrimental effects of both white and silver fillings – and I would tell you to try and avoid them.I would choose a little fluoride rinsing to avoid the chance of needing a filling – I look at fluoride rinsing as a kind of "insurance policy" to avoid fillings! If you have no damage to your teeth, and white, healthy teeth with no sensitivity, no gum recession and no plaque – then you do not need fluoride.If you have stained or dark teeth, sensitivity or broken, weak, "aging" or breaking teeth – then fluoride with xylitol (used in the way I describe on the website – with the products that I suggest : a 0.05% dilution of fluoride – NOT stronger) this combination will help you reverse problems and whiten your teeth. I think you may enjoy the chapter I have written on fluoride in Kiss Your Dentist Goodbye.I discuss the fact that I have concerns about putting it in drinking water ( I filter it out of my drinking water here in Upstate NY) and I would never suggest giving it to kids as a supplement, nor the stronger gels that are prescribed. Use it the way I suggest and you will see a healthy shine on your enamel in just a few weeks.www.ZelliesCleanWhiteTeeth.com Hope this explains a little about this very complicated subject. http://www.zellies.com26 Corporate WoodsRochester, NY 14623
