Fluoride
The primary function of fluoride is in the mineralization of bones and teeth. It is fascinating to know that fluoride is also responsible for protecting the teeth from dental caries. It is now routinely added to most toothpaste to prevent tooth-related problems.
In sporadic cases, large amounts of fluoride can cause fluorosis, and symptoms may be mild such as mottling and crumbling of the teeth. However, more severe symptoms cause skeletal changes like calcification of ligaments and tendons that directly leads to muscle, joint, and bone problems.
Moreover, fluoride is found in fluoridated water, tea, and fish. The diet allows you to get only 25% of total intake. However, the addition of fluoride to toothpaste is also essential in those areas where the water supply is low in fluoride.
