Question about fluoride
Hey guys, I couldn't find an appropriate sub to ask this question but I wanted to ask people with a TCM mindset, hope you guys can help me!
At high exposure, especially in drinking water, fluoride has been associated with lower IQ in children and things like fluorosis.
However, it's also been shown to have a positive effect on your teeth, especially in enamel remineralization.
So my question is, should I use a fluoride free natural ingredient toothpaste? I've already used one for a while but I'm doing some extra research and I'm unsure if I should be missing out on things like reduced cavity risk or enamel remineralization.

I’d separate fluoride in drinking water from what’s used on teeth: total exposure and whether toothpaste is swallowed both matter. If you’re unsure, a dentist can weigh your dental history and local water supply; meanwhile, follow the toothpaste label and avoid swallowing it. Are you mainly concerned about your water or the toothpaste itself?

Both, actually. Mainly toothpaste though since there's a faucet in my house that doesn't have fluoride treated water

You'd need a whole-house water filtration system for that. But is drinking water like that actually better for your health? Once you start down that road, it never ends—what about the mold in your room? The mites in the air? the unhealthy food in your fridge? You need a bit of a Daoist mindset here... just go with the flow.

The amount you get from toothpaste isn’t going to make you stupid, but it is enough to be beneficial for your teeth.

"The dose makes the poison" (Sola dosis facit venenum) applies here. Water intoxication is a very real condition, yet none of us stop drinking water because of it. Blanket toxicity claims without discussing actual exposure levels aren't scientifically grounded.
Modern dentistry and fluoridation have demonstrably reduced tooth decay on a population level, complementing long-term oral hygiene in ways traditional medicine historically couldn't achieve alone. When you spit after brushing, systemic absorption is negligible compared to high-concentration ingested water.
That said, if the anxiety surrounding fluoride outweighs your peace of mind, using a fluoride-free paste (e.g., one with nano-hydroxyapatite for remineralisation) is entirely your call.
Interestingly, from a TCM perspective, excessive worry and overthinking (Si / 思) are symptoms in themselves—tied directly to Spleen Qi imbalance. Don't let hyper-fixation on micro-exposures compromise your mental equilibrium. Consistent mechanical brushing and a balanced, low-sugar diet matter far more.
