[5] Although it is helpful topically for dental health in low dosage, chronic ingestion of fluoride in large amounts interferes with bone formation.
Rates of allergies differ between adults and children. Children can sometimes outgrow peanut allergies. Egg allergies affect one to two percent of children but are outgrown by about two-thirds of children by the age of 5. [47] The sensitivity is usually to proteins in the white, rather than the yolk.

Dental fluorosis is caused by a higher than normal amount of fluoride ingestion whilst teeth are forming. Primary dentine fluorosis and enamel fluorosis can only happen during tooth formation, so fluoride exposure occurs in childhood.

For women ages 18 and older, the AI is set at 2.9 mg/day (includes pregnancy and lactation). For men, the value is 3.4 mg/day. For children ages 1–17 years, the AIs increase with age from 0.6 to 3.2 mg/day. These AIs are comparable to the U.S. AIs. [22] The EFSA reviewed safety evidence and set an adult UL at 7.0 mg/day (lower for children). [23]
