The main opponent of water fluoridation is excessive intake of fluorides that can cause dental fluorosis, a dental disease that can also destroy or malform teeth especially children’s teeth. However, the tolerable intake level for people 9 years old and above is ten part per million (ppm). This means that if a drink is fluoridated to 1 ppm, it would take ingestion of 10 liters of the drink before excess fluoridation is achieved. It is highly improbable to drink that much liquid. Children below 9 years old however are more sensitive to flourides. Infants up to 12 months must not be given fluoridated drinks in excess of 0.9 mg/day or less than a liter of 1ppm fluoridated drinks. Children 1-3 is less sensitive but still has a limit of 1.3 mg/day or 1.3 liters of 1 ppm fluoride water which corresponds to 5 250-ml juice tetra packs. Children 4-8 years old have until 2.2 mg/day or 2.2 liters per day of 1 ppm fluoride water or 8.5 250-ml juice tetra packs. Thus, there is more chances of excess here and maybe a 0.5 ppm concentration would be better. This double values of ingestion and is therefore safer. At 2 liters per day consumption by adults, this still results in 1 mg/day which is actually lower than recommended.

Anyway, this is a layman’s analysis of the benefits of fluoridation. It is best to refer to dental professionals on these matters as well as information on dental implants, like dental implants bolton, England. For dental jobs and dental courses, please refer to other websites.
