Why Is There Fluoride in Water? Is It Effective?

Based on nearly 100 randomized controlled trials, fluoride toothpaste reduces dental cavity rates, but what about just adding fluoride to the water supply?

Like everything in medicine, it’s a matter of balancing the risks and benefits.

This is the first video in a five-part series on water fluoridation. Stay tuned for:
• Side Effects of Water Fluoridation: Dental Fluorosis ( )
• Is Water Fluoridation Safe? ( )
• Why I Changed My Mind on Water Fluoridation ( )
• Medicine’s Response to the Changing Science on Fluoride Safety ( )

    How do I get to the other videos in this series?

    • @themotivator2587 says:

      It looks like this is the first, and it came out today. The next four should be released over the next few days.

    I love this channel!

  • @ScarCaskt says:

    If they cared about our teeth, why is dental insurance separate from health insurance?

    • @johnpurser2798 says:

      Who is “they”? And if “they” cared so much about health why have “insurance”? Why not just have health care?

      Money

    • @velatoget says:

      @@johnpurser2798 “They” means the people we are talking about. In this case, we’re talking about fluoride lobbyists (people and companies who have financial interest in disposing of their aluminum biproduct for profit), and companies that profit from fluoride directly.

      “Who is they” is a strange question. Does it matter?

    • @pdblouin says:

      ​@@velatoget You’re saying Big Fluoride is the reason we have separate dental insurance? But what about Big Dentist? Aren’t they lobbying for worse teeth?

    • @johnpurser2798 says:

      @@velatoget Well you care who “they” are and what “they” believe so yes, who they are matters. And since you still don’t know who “they” are and the “they” you identified is not who we’re talking about I would guess the topic still needs clarification.

      The video is a nice presentation on the facts of the matter, independent of what any hypothetical “they” wants.

    Thank you so much for doing this topic

  • @tommanley2924 says:

    Why, because they had a ton of after product called fluoride and they needed a way to profit from it, that’s how it happened.

  • @sinun82 says:

    The words “safe and effective” have been abused lately

  • @johnpurser2798 says:

    Some of the first conspiracy theories I heard on the internet were based on “Water fluoridation makes you a slave!” I had no idea the roots of this nonsense went back so far.

  • @keithlb1 says:

    I don’t use fluoridated toothpaste because if you are eating cruciferous veggies to reduce high blood pressure and heart disease, the Esselstyn heart reversal diet, he says fluoride interferes with the breakdown of nitrites as you chew these greens with some balsamic vinegar for optimal nitrate absorption into the endothelial tissue

  • @QuocTaHoang says:

    Finally!!! I waited for a whole year since you first announced about Fluoride bad side effect in Feb 2023.

  • @SALVATl0N says:

    Thank you for covering this topic! I hope you will address the widespread use of fluoride, and if there was an issue, it seems like we would have seen it long ago. I wonder if there’s any thing that we have given humans on such a mass scale as much as fluoride?

  • @ruthohare9840 says:

    Went down that rabbit hole when my daughter was a baby and spoiler warning the costs far outweigh the claimed benefits. There is no way adding it to the water is ethically justified.

  • @Albopepper says:

    At what cost!? Nooo!!! I’m not gonna drink any water til I find out! 🤣

  • @deavman says:

    CDC..safe, effective..misinformation..
    Words that make me go “Hummmm…”

  • @rosariomoschitto4037 says:

    Fluoride is worthwhile when limited to topical application (i.e. toothpaste). Consuming fluoride on the other hand (i.e. drinking water) is more harmful than beneficial.

  • @LeckieInstallsLondon says:

    Whoa what a cliffhanger 😂

  • @JMo268 says:

    It’s a cliffhanger!

  • @jdstep97 says:

    I’m not convinced. I’ll continue avoiding fluoride. Thanks for the information, though, Doc.

  • @tayloranderson456 says:

    Mind blowing that instead of just some sensible sugar regulation we decide to manage the disease instead of fix the cause and prevent it.

    Knew childhood friend teeth turned grey like metal from fluoride
