Drinking bottled water will not necessarily ensure that you're not exposing yourself to fluoride, health experts say.
Fluoride has long been added to toothpaste as well as tap water in order to prevent tooth decay, according to AWM. However, recent studies have shown that the chemical can do more harm than good, as overexposure can actually lead to tooth decay and malformation.
Fluoride can also cause cognitive issues and brain disorders. A study done in China concluded that children who were exposed to the chemical on a daily basis had lower IQs than children who were exposed less often.
"Fluoride seems to fit in with lead, mercury, and other poisons that cause chemical brain drain," researcher Phillipe Grandjean said, according to AWM. "The effect of each toxicant may seem small, but the combined damage on a population scale can be serious, especially because the brain power of the next generation is crucial to all of us."

As such, many people have begun to avoid drinking tap water, opting for bottled water instead.
But some bottled water is actually municipal tap water and might, therefore, contain fluoride, according to The Arab Tribune. Furthermore, certain spring water is reported to contain the chemical.
You can usually tell if your bottled water contains fluoride by looking at the label. If it says the water was distilled or filtered by reverse osmosis, it does not contain fluoride. If you're unsure, you can always call the bottling company and inquire.
The following is a list of bottled water brands to avoid, according to AWM:
