Fluoride: Myths and Facts

Myths or facts concept

The idea of fluoridated water always causes a stir, especially among its opponents. There are numerous myths about fluoride, none of which have any truth to them. Read on to find out some common myths and facts about fluoride.

Does Fluoride Belong in Water?


The presence of fluoride in water isn't natural.


Fluoride does occur naturally in practically all water supplies. It is just not enough in itself to protect your teeth. Having an optimum level of fluoride in water is recommended for protecting your teeth.

Should Children Use Fluoridated Toothpaste?


Children shouldn't be using fluoridated toothpaste in order to prevent them from swallowing excess fluoride.


The American Dental Association had indeed recommended this. However, after further research, they reversed their statements and now actively recommend children under 3 use a pea-sized amount of fluoridated toothpaste. Parents should always supervise their children when they are brushing their teeth.

Does Fluoride Damage Teeth?


Fluoride severely damages your teeth, causing Dental Fluorosis.


It is not so much a myth but more of a wild exaggeration. Dental Fluorosis happens when children consume excess amounts of fluoride. Consequently, their adult teeth have white spots which are minimally noticeable and purely cosmetic.

Does Fluoride Cause Low IQ in Children?


According to a study published in Environmental Health Perspectives, consuming fluoride during pregnancy can affect your baby's mental development and causes low IQ in children.


This is another fact that has been blown out of proportion. The study was conducted in Mexico, where the water's fluoride levels are already elevated. Moreover, fluoride is added to even the salt.

The American Dental Association remains firm on its stance that such cases are caused by excess amounts of fluoride. Water fluoridation programs in the United States use optimum levels, thereby making the study inapplicable to the US.


The ADA and CDC both agree that fluoride is highly beneficial for everyone's teeth, going so far as to claim it is "nature's way" to prevent tooth decay. Visit our website for more information or schedule an appointment with our dentist in Portsmouth, NH.
