Everyone’s arguing about fluoride online — TikTok “experts” claim it lowers IQ, while your dentist keeps recommending it. Here’s the actual 2025 truth from a Gresham practice that sees the results every day: Professional fluoride treatments are still one of the fastest, safest, cheapest ways to stop cavities before they start.
At Premier Dentistry, we applied fluoride to over 1,200 patients last year alone. The proof? Dramatically fewer fillings needed on recall visits.
Yes, there was a 2024 NTP report. No, it does not apply to the fluoride we paint on your teeth for 2 minutes. Keep reading — we break down the real science (with sources) so you can decide with facts, not fear.
Professional fluoride comes in four main forms we use at Premier Dentistry:
Compare that to your toothpaste at home (1,000–1,500 ppm) — professional strength is 15–20× higher but applied topically and professionally controlled.
The American Dental Association, CDC, and AAP all reaffirmed in 2025 that fluoride remains the single most effective public health measure for preventing decay.
You probably do if you have any of these:
Kids 6 months–16 years, adults with any risk factor, and seniors with root exposure benefit most.
No downtime. Don’t eat crunchy food or brush for 4–6 hours. That’s it. Most patients say “I didn’t feel anything.”
The 2024 NTP monograph (final August 2024) found “moderate confidence” that fluoride levels above 1.5 ppm in drinking water are linked to slightly lower IQ in children.
Key facts the fear videos leave out:
Swallowing pea-sized toothpaste daily? Fine. Swallowing an entire tube? Dangerous (like any product). Professional application is controlled and safe.
Marketing hype losers: most “high-fluoride natural” pastes under 1,000 ppm — basically regular toothpaste with a higher price.
These have solid 2025 evidence:
nHAP is the only real fluoride-free alternative with comparable data. We stock it for patients who refuse fluoride.
Most PPO plans cover professional fluoride 100% twice per year.
Is fluoride safe for pregnant women? Yes — ADA/ACP 2025 guidelines say benefits outweigh any theoretical risk.
Safe for babies under 6 months? No varnish; we use smear of fluoride toothpaste only.
What about thyroid issues? No evidence at dental doses; high-dose studies were 5–10× higher.
Can adults over 50 benefit? Absolutely — root caries prevention is huge.
Can I eat after fluoride varnish? Soft foods only for 4–6 hours.
Does it stain teeth? New 2025 varnishes are clear or white — no yellow tint gone by morning.
Is the “rat study” real? Those used 50–100× human doses — irrelevant.
Yes. 100%. The science is overwhelming: fluoride treatments prevent way more harm than any hypothetical risk at dental levels.
Every major health organization on earth agrees.
