There is no agreed ratio of benefits from topical and systemic application of fluoride in human body but the estimated ratios are between 80/20 or 90/10: 80-90% for topical application (mouth only) and 10-20% for systemic (ingested).
The claim is that about 80-90% of the benefits come from fluoridated water in the mouth (like a mouthwash) directly reacting with the surface of teeth. The remaining 10-20% of the alleged benefits come from the ingested fluoride that then enters the bloodstream and allegedly fixes the teeth from that end.
In that case if fluoride is so effective at preventing dental decay but the vast majority of the benefits (80-90%) come from washing teeth in fluoridated toothpaste, fluoridated liquid (a mouth wash) and fluoridated water why in this particular case DO WE HAVE TO DRINK IT on a daily basis and in large quantities?
Do you swallow your fluoridated toothpaste or fluoridated mouthwash?
No, you don’t. It says on the packaging not to swallow it because it will make you sick!
Still you supposed to drink the fluoridated water!
This will help you understand the problem better:
| Fluoride source | Freedom of choice | Is ingestion poisonous? | Exposure | Exposure (daily) | Does fluoride enter my bloodstream? | Systemic (benefits) | Topical (benefits) |
| Toothpaste | ✅ | YES ☠️ | Minimal | ~0.4 mg* | Accidental 😔 | 0% | 80-90% |
| Mouthwash | ✅ | YES ☠️ | Minimal | ~0.4 mg* | Accidental 😔 | 0% | 80-90% |
| Fluoridated water | ❌ | NO ⁉️ | Guaranteed | ~1.5 mg** | YES 💀 | 10-20% ⁉️ | 80-90% |
| other parts of England, Scotland, Wales | ✅ | YES ☠️ | Minimal | 0 mg | NO 😊 | n/a | n/a |
(*) assuming 2 mouth washes a day and this is ONLY accidental ingestion. Not all toothpaste is expectorated. Studies estimate adults swallow about 10-30% of the paste used. Young children, with poorer swallowing control (+ tasty toothpaste) may swallow 30-65%.
(**) assuming you drink 1.5 litres of fluoridated water and have one shower in fluoridated water a day. You ingest over 1mg and inhale about 0.3mg of fluoride per shower.
The use of fluoridated toothpaste and any other medicinal product like a mouthwash is VOLUNTARY.
Drinking fluoridated water is NOT VOLUNTARY and on top of that has a compounding effect because it is easy to switch to a non-fluoridated toothpaste but it isn’t easy (or impossible) to switch to non-fluoridated water (usually only one water supplier).
Based on the above table there is little to no justification for the fluoridation of drinking water or bottled drinking water.
Why the authority forces only on SOME(?!) of the English citizens to drink such “water” if the systemic benefits are questionable and only at 10-20%?
While at the same time from the chemistry corner we learn that because of its exceptional reactivity Fluoride is nothing but a poison especially when it enters your body.
The so called water forced by Severn Trent Water is not a drinking water but a fluoridated mouth wash. That’s why you should immediately stop drinking it and stop paying them for this medicinal product.
The only thing you can do with this “drinking water” is to take it into your mouth but only to spit it out.
From the above comparison you can clearly see that the people living in fluoridated areas are exposed to at least 3x HIGHER, DAILY AND GUARANTEED amounts of fluoride comparing to people in not fluoridated areas and only with accidental exposure from the ingestion of a toothpaste or a mouthwash.
TIP
Did you know that the advised amount of toothpaste for adults is pea size while for children is rice size?
Do you think this is the amount people and kids put on their toothbrushes? or perhaps a lot more?
And these prescribed amounts are not what we use to see in the TV commercials.
