|Description||Fluoride is a mineral commonly known for its effects on our teeth.|
|Function/ Used for||Fluoride is important to help keep teeth strong and healthy1.|
|Intake||EU NRV: 3.5mg
UK average daily intake: requirements vary depending on age and gender. The UK National Diet and Nutrition Survey lists up-to-date intake requirements and average intakes2.
|As a supplement||Typically found as an ingredient in toothpastes and mouthwashes.
Also, can be found as a supplement for use in certain circumstances; typically, only for those known to have a lack of intake from food and drink and/or exposure to fluoride through dental products.
|Found in (dietary sources)||Fluoride is found in tea, marine fish, fluoridated water, foods and beverages made from fluoridated water, toothpaste and other dental products containing fluoride.
|Deficiency||Although there is no deficiency disease for fluoride, low fluoride intake and/or poor dental hygiene (or brushing with fluoride-free toothpaste) can lead to tooth decay3.|
|Precautions and contraindications||Safe Upper Level (Guidance Level): 7mg/day3|
|Use in pregnancy and breastfeeding||There is no evidence of adverse effects in pregnancy at normal intakes.|
|Interactions e.g. with other medications||Fluoride is not known to have any clinically relevant interactions with medications.|
|Adverse effects||Chronic high intakes can lead to skeletal or tooth fluorosis. Fluorosis of the teeth is much more common and leads to build up of fluoride in dental enamel causing structural and compositional changes (e.g. white mottling, yellow marks and pits on teeth) which does not actually do any harm to the teeth. The much rarer skeletal fluorosis however can lead to bone deformation, stiffness of joints, pain and increased risk of fracture3.|
