Is hydrogen fluoride a strong acid?
Hydrofluoric acid (HF) is a weak acid mainly because it forms stable species after it dissociates. … However, it’s classified as a weak acid rather than a strong acid. This makes HF the only hydrohalic acid that isn’t classified as a strong acid (e.g., HCl, HBr, HI). What fluoride does to the body?
In simple terms, fluoride helps prevent cavities. It helps during the remineralization of teeth by strengthening enamel and protecting it against tooth decay. In young children, fluoride helps to harden the enamel of their baby and permanent teeth before they begin to come in.

Why you shouldn’t use fluoride toothpaste?
Swallowing fluoride toothpaste can lead to fluorosis, which interferes with the development of tooth enamel and can result in white streaks on the teeth, and gastrointestinal problems if the amount is large enough.
Why is fluoride in drinking water?
Adding fluoride to the water supply reduces the incidence of tooth decay. Fluoride protects teeth from decay by demineralization and remineralization. Too much fluoride can lead to dental fluorosis or skeletal fluorosis, which can damage bones and joints.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
