Dental products are a major source of fluoride exposure, particularly for children. Fluoridated dental products include toothpastes, mouth rinses, fluoride gels, fluoride varnishes, and fluoride supplements.
How Much Fluoride Are in these Products?
Fluoride Toothpastes (1,000 to 1,500 ppm)
- Over 95% of toothpastes now contain fluoride.
- A single strip of toothpaste covering the length of a child’s brush contains between 0.75 to 1.5 mg of fluoride. This exceeds the amount of fluoride in most prescription fluoride supplements (0.25 to 1.0 mg).
- Many young children swallow over 50% of the paste added to their brush, particularly if they use candy-flavored varieties and if they are not supervised during brushing to ensure they spit and fully rinse. Research has shown that some children swallow more fluoride from toothpaste alone than is recommended from all sources combined.
- Although dentists now recommend that children only use “a pea-sized amount” of toothpaste, many children use more than this, particularly when the toothpaste has bubble gum and watermelon flavors.
- Ingesting toothpaste during childhood is a major risk factor for dental fluorosis, and can also cause symptoms of acute fluoride toxicity (e.g., stomach pain, etc).
- The FDA now requires a poison warning on all fluoride toothpastes sold in the U.S.
- Some mouth rinses now contain fluoride.
- A single mL of fluoride mouthrinse contains roughly 0.25 mg of fluoride.
- Between 5 to 15 mL are generally used per rinse, which equates to 1.25 to 3.75 mg of fluoride.
- Little data is available to show how much of the rinse is ingested.
- Dentists prescribe self-applied gels to those at high-risk of tooth decay.
- Each mL of gel contains 5 mg of fluoride.
- Without taking extraordinary precaution to limit the amount of gel that is applied and reduce the amount of gel that is ingested, self-application can result in dangerously high fluoride exposures.
- A single mL of gel contains 12.3 mg of fluoride.
- Dentists are now recommended to apply no more than 4 mL when treating children (=49 mg of fluoride), and no more than 8 mL when treating adults (=98 mg of fluoride).
- The highly acidic nature of the gel greatly increases saliva flow, which makes it largely impossible to avoid swallowing large amounts of it. While few measures were used in the past to limit the amount of fluoride ingested, dentists are now advised to use suction devices and to encourage the child to fully rinse and spit at the end of the treatment.
- Even when precautionary measures are taken, children swallow an average of 7.7 mg per treatment
- Adults swallow an average of 10.3 mg per treatment.
- Symptoms of acute fluoride toxicity (e.g., nausea and vomiting) are common in children receiving fluoride gels.
- Although dental researchers only recommend topical fluoride gels for patients with high risk for cavities, surveys have shown that dentists routinely apply gels to most of their patients.
- A single mL contains 22.6 mg of fluoride. Dentists apply 0.5 to 1 mL per treatment.
- Since the varnish eventually wears off the teeth, all of the fluoride that is applied (=11.3 to 22.6 mg) is ingested.
- Dentists apply varnishes up to 4 times a year in children with high risk for cavities.
- Supplements contain between 0.25 to 1 mg of fluoride per drop, tablet, or lozenge. The amount depends on the age of the child.
- Supplements are available by prescription only. Unlike dietary supplements, fluoride supplements cannot be purchased over the counter.
- Despite being prescribed for over 50 years, the FDA has never approved fluoride supplements as safe or effective.
- The ADA no longer recommends for infants under 6 months of age.
- Supplements were designed to only be used in non-fluoridated areas as a substitute for fluoridated water. Surveys have repeatedly found, however, that some dentists prescribe supplements to children living in fluoridated areas as well.
- Current supplement use greatly increases a child’s risk of developing dental fluorosis, while doing little to prevent tooth decay.

Major Corporations Changing Statements on Safety of Fluorides
In a development certain to gain the attention of risk managers at water utilities around the world, key toothpaste manufacturers and other organizations are changing how they portray the safety or risks of fluorides and water fluoridation.
Allergy to Fluoride Toothpaste - Additional Info
Information about allergic skin reactions to fluoride toothpaste.
Allergy to Fluoride Toothpaste – New Report
The current issue of the journal Dermatology contains an case report which concludes that fluoridated toothpaste may be a cause of “Recurrent Aphthous Stomatitis”, a condition more commonly known as “canker sores.”
Acute Fluoride Toxicity from Toothpaste Ingestion
The Food & Drug Administration now requires that all fluoride toothpastes sold in the United States bear the following poison warning: "WARNING: Keep out of reach of children under 6 years of age. If you accidentally swallow more than used for brushing, seek professional help or contact a poison control center immediately." The
Fluoride Dentrifice and Stomatitis
Statistical data of 133 patients who have been using fluoride dental cream or powder have been presented. Each has developed intraoral ulcerative lesions. Many have been treated for other complaints without clearance of the lesions. Age is not significant. Repeated insults with the fluoride dentrifices produced increasingly severe excoriations. There seems to be nothing specific about the lesions to differentiate them from other diseases of an oral nature.
Allergy to Fluoride
Six children and one adult exhibited various allergic reactions after the use of toothpaste and vitaimin preparations containing fluoride. The following conditions were encountered: Urticaria, exfoliative dermatitis, atopic dermatitis, stomatitis, gastro-intestinal and respiratory allergy.
The Wichita Eagle's Fact-Challenged Reporting on Fluoride
During the run-up to a referendum on fluoridation in Wichita, Kansas, the city's local paper (the Wichita Eagle) became an ardent advocate of fluoridated water. In it's zeal for fluoridation, the Eagle turned its backs on one of the basic tenets of good journalism by allowing the paper's editorial view
Fluoride Intake from Toothpaste vs. Recommended Daily Intake from All Sources
For many children, fluoride toothpaste is the largest source of fluoride intake. One strip of fluoridated toothpaste on a child-sized toothbrush contains between 0.75 and 1.5 mg of fluoride, which is more fluoride than is found in many prescription fluoride supplements (0.25 to 1.0 mg per tablet). Since young children are
