Should Fluoride Really Be in Our Drinking Water? The Gen Z Health Breakdown

Fluoride in Drinking Water: Helpful or Harmful?

If you grew up in the U.S. or most Western countries, chances are you have been sipping on fluoridated tap water your whole life without really thinking about it. But lately, more Gen Z voices are asking: is fluoride in drinking water actually good for us, or are we just blindly following an outdated public health experiment?

When I was a kid, fluoride was just “the weird foamy stuff at the dentist” that tasted like bubblegum chalk. It was not until college, when I noticed “fluoride free” toothpaste trending in health stores, that I realized this was a debate. Some friends swear fluoride is essential for strong teeth. Others avoid it like it is a government conspiracy. So what is the deal? Let’s break it down.

Why Fluoride Ended Up in Our Water in the First Place

Back in the 1940s, dentists noticed that communities with naturally higher levels of fluoride in water had fewer cavities. In 1945, Grand Rapids, Michigan, became the first city to officially add fluoride to its water supply.

The idea was simple: add just enough fluoride to strengthen tooth enamel and reduce cavities across entire populations. And it worked. By the 1960s, cavity rates in kids dropped dramatically in fluoridated areas. Today, about 70 percent of the U.S. population drinks fluoridated tap water.

The Benefits: Why Public Health Still Supports It

Dentists and health organizations such as the CDC and WHO still back fluoride as a safe, effective way to prevent tooth decay.

Here is what the science says:

• Reduces cavities by about 25 percent in both kids and adults
• Strengthens enamel, making teeth more resistant to acid and bacteria
• Affordable and accessible, especially for lower income communities that may not have access to regular dental care

For many, fluoridation is considered one of the top public health wins of the 20th century. It is like a vaccine for your teeth, but delivered through your sink.

The Concerns: Why People Are Questioning It

Here is where things get messy. Critics argue fluoride might not be the harmless dental hero we have been told it is.

• Overexposure risk: Too much fluoride can cause dental fluorosis, which shows up as white streaks on teeth, and in rare cases skeletal fluorosis that causes bone problems
• Possible health effects: Some studies link high fluoride exposure to thyroid issues, lowered IQ in children, or other health risks. Critics argue more research is needed, especially on long term effects
• Consent and choice: Adding fluoride to public water means everyone consumes it, whether they want to or not. For many, that feels like forced medication
• Do we still need it? With modern toothpaste, better diets, and dental care, some argue fluoride in water is outdated

I remember a roommate in college who only bought bottled spring water because she did not trust tap water fluoridation. At the time, I thought she was overreacting. But the more I read, the more I understood why she and a growing number of Gen Z folks are questioning it.

Gen Z's Take: Rethinking "Default" Health Decisions

Gen Z does not just accept things because they have always been that way. From food additives to beauty products, we want transparency. Fluoride is no different.

• Natural lifestyle trends: Fluoride free toothpaste is blowing up, especially from eco conscious brands
• Skepticism of government health policies: After the pandemic, trust in top down decisions is complicated
• Focus on holistic health: We are more likely to say, “Maybe diet, oral hygiene, and access to care matter more than dosing everyone with fluoride”

That said, many Gen Z dentists and scientists still support fluoridation, pointing out that the risks of tooth decay, especially in underserved communities, outweigh the minimal risks of fluoride.

So, Should We Keep It?

Here is the balanced take:

• Yes, fluoride helps teeth. That part is not up for debate
• No, it is not risk free. But at regulated levels, most evidence says it is safe
• The controversy is valid. People should have a say in what is added to their water

Some communities are choosing to ditch fluoridation, while others double down on it. Gen Z will likely push for more choice, like filters, fluoridated versus non fluoridated water options, and more research into alternatives.

My Take

Personally, I use regular toothpaste with fluoride, but I also keep an open mind about fluoride free alternatives. I grew up on tap water and have had maybe two cavities in my life, so maybe it worked. But I do not love the idea that something gets added to my water without me ever really consenting. I think giving people the choice would solve a lot of the debate.

Fluoride in drinking water sits at that weird intersection of science, health, and personal choice. It has helped millions avoid painful cavities, but it also raises questions about consent, safety, and whether it is still necessary in 2025.

The truth? Whether you are team tap water forever or fluoride free lifestyle, what matters most is staying informed, brushing twice a day, flossing, and making the health choice that feels right for you.
