Will Substantial Fluroide Exposure Indicated in the Sample Test

Not all fluorides are excreted that easily. For example, a contaminant high in aluminum may cause the fluoride to penetrate the blood brain barrier as an aluminum-fluoride attachment occurs. This happened the most during the 1960s-2000s when fluoride toothpaste in aluminum tubes were used. It can also occur if the food contaminant is high in alumimum too, but I suspect other heavy metals may encourage to prevent fluoride from full excretion, one obvious example is high calcium in the body which can attach itself to the body's tissues, such as pineal gland, where calcium fluoride (with other metals) accumulate throughout life so much that scientist use this accumulation to measure this as a biomarker to aging.

Hence long term exposure at least a year or more to flouride contamination, will result in fluoride accumulation which may show itself in hair mineral analysis. Too much fluoride that can result in a common bone conditions of fluorosis obviously could kill you so that could indicate that it is not excreted as much as most people wish. If you have white spots on the front teeth, this indicates already some fluoride exposure, as other areas of the teeth already become mottled while more severe leads to brown teeth and the teeth never gets white when drinking water high in fluoride. This is again from excess fluoride use, and in most cases this becomes more common then in the past, hence fluoride such as this, may show up in other analysis. Even a physical examination is even easy to see.
