According to the International Association of Oral Medicine and Toxicology (IAOMT), an organization that campaigns against the use of added fluoride, it may also contribute to the following health problems:

acne and other skin problems

cardiovascular problems, including arteriosclerosis and arterial calcification, high blood pressure, myocardial damage, cardiac insufficiency, and heart failure

reproductive issues, such as lower fertility and early puberty in girls

thyroid dysfunction

conditions affecting the joints and bones, such as osteoarthritis, bone cancer, and temporomandibular joint disorder (TMJ)

neurological problems, possibly leading to ADHD

One review describes fluoride as an “extreme electron scavenger” with an “insatiable appetite for calcium.” The researchers call for the balance of risks and benefits to be reconsidered.

Fluoride poisoning

Acute, high-level exposure to fluoride can lead to:

abdominal pain

excessive saliva

nausea and vomiting

seizures and muscle spasms

This will not result from drinking tap water. It is only likely to happen in cases of accidental contamination of drinking water, due, for example to an industrial fire or explosion.

It is worth remembering that many substances are harmful in large quantities but helpful in small amounts.

Uses

Fluoride exists in many water supplies, and it is added to drinking water in many countries.

 

Fluoride is added to many dental products.

It is also used in the following dental products:

toothpaste

cements and fillings

gels and mouthwashes

varnishes

some brands of floss

fluoride supplements, recommended in areas where water is not fluoridated

Non-dental sources of fluoride include:

drugs containing per fluorinated compounds

food and beverages made with water that contains fluoride

pesticides

waterproof and stain-resistant items with PFCs

Excess fluoride exposure may come from:

public water fluoridation

high concentrations of fluoride in natural fresh water

fluoridated mouth rinse or toothpaste

untested bottled water

inappropriate use of fluoride supplements

some foods

Not all fluoride exposure is due to adding the chemical to water and dental products.

Some geographical areas have drinking water that is naturally high in fluoride, for example, southern Asia, the eastern Mediterranean, and Africa.

Side effects

Possible side effects of excessive fluoride intake include:

discoloration of teeth

bone problems

Other possible side effects are listed under the “risks” section above.
