How much fluoride can be consumed?
According to the EPA, typical daily fluoride intakes in the United States from foods and beverages (including fluoridated drinking water) are 1.2 to 1.6 mg for infants and toddlers younger than 4 years, 2.0 to 2.2 mg for children aged 4–11 years, 2.4 mg for those aged 11–14 years, and 2.9 mg for adults [10].
How much fluoride is in a fluoride treatment?
Fluoride Varnish Varnishes are available as sodium fluoride (2.26% [22,600 ppm] fluoride) or difluorsilane (0.1% [1,000 ppm] fluoride) preparations. High-concentration fluoride varnish is painted by dental or other health care professionals directly onto the teeth.
What is the tolerable upper intake level for fluoride?
The upper tolerable intake limit (UL) for fluoride (7 mg/day) for adults and children over the age of 15 is only exceeded in areas with high levels of natural fluoride in water, whereas the UL would not be exceeded for adults and children over the age of 15 living in an area with fluoridated drinking water.
What concentration of fluoride do dentists use?
Community water fluoridation is the process of adjusting the fluoride content of fluoride-deficient water to the recommended level for optimal dental health, which is currently recommended at 0.7 parts fluoride per million parts water.
How can I add fluoride to my diet?
In addition to drinking more tap water, experts recommend incorporating some more of these natural fluoridated foods and beverages into your diet. These options include black tea, white wine, avocados, peaches, lettuce, and radishes. Of course, eat these foods fresh for the best fluoride boost.
Can you drink alcohol after fluoride treatment?
If a varnish pen is used for the fluoride treatment, avoid eating anything hot or hard within the first 6 hours after the treatment. Also, alcohol is prohibited within these 6 hours. You can, however, consume cold drinks and soft foods immediately after the treatment.
What concentration of fluoride in a municipal water supply is required to significantly reduce the caries incidence without causing dental fluorosis?
For community water systems that add fluoride to their water, PHS recommends a fluoride concentration of 0.7 mg/L (parts per million [ppm]) to maintain caries prevention benefits and reduce the risk of dental fluorosis.
What type of fluoride is found in drinking water?
sodium fluoride
Fluoride in drinking water The decision to add fluoride to drinking water is made at the state or local level. The types of fluoride added to different water systems include fluorosilicic acid, sodium fluorosilicate, and sodium fluoride.

Which fluoride is best?
One study even found that stannous fluoride was far more effective in fighting bacteria compared to sodium fluoride. As a rule of thumb, if you’re looking for all-around protection (and not just cavity prevention), then stannous fluoride is the preferred fluoride of choice for your oral health.
What percentage of fluoride should be in toothpaste?
High-fluoride toothpaste generally contains 1.1 percent (5,000 ppm) sodium fluoride and is typically used in adults with extensive tooth damage or medical conditions that place them at risk of cavities (including dentures, orthodontic devices, or dry mouth caused by disease, medications, or cancer therapy).
What is the pH of acidulated phosphate fluoride?
Acidulated phosphate fluoride (APF 1.23%, 12,300 ppm F, pH 3.2) is available as solution, gel or thixotropic gel, and as a foam. The thixotropic gel is preferred because of pH stability and reduced likelihood of swallowing.
How much fluoride should be in drinking water?
In 1986, guidelines from the U.S. Environmental Protection Agency (EPA) established a maximum allowable concentration of 4.0 mg/L fluoride in public drinking water systems to prevent adverse effects from fluoride exposure (such as bone disease) and a recommended maximum concentration of 2.0 mg/L to prevent dental fluorosis [ 3, 10 ].
How is individual level of fluoride status assessed?
Individual fluoride status is not typically assessed, although fluoride concentrations can be measured in plasma, saliva, urine, bones, nails, hair, and teeth [ 4, 5 ]. Criteria for adequate, high, or low levels of fluoride in the body have not been established.
Why is fluoride added to tap water in the US?
Fluoridated drinking water Since 1962, the U.S. Public Health Service has recommended the addition of fluoride to drinking (tap) water to reduce the risk and severity of dental caries, one of the most common chronic diseases in children [7].
