... Like, having an appointment to their dentist ?
It is funny you make dentistry sound as it was like fixing one's car by oneself. We are talking about healthcare, you cannot just assume the bulk of the people within one country are going to invent a new way to fix their own teeth, without having the knowledge and the degree a dentist has.
What is next on your predictions? Once people do not get access to anti-polio vaccines people will figure out by themselves ways to cure the irreversible limb numbing and paralysis caused by polio?
Are you also going to suggest for cancer patients to stop to go through their treatment, so they can figure out how to be their own surgeons and self-extract their tumors?
I know people of the United States being dumb is a stereotype, but people like you do not help to dispell such stereotypes.
You really need to look at what you are saying. It's the medical - prompted by the medical leaders - that is doing all those dangerous things you talk about. And the reason why you don't recognize it is probably because you have been dumbed down by fluoride.
For example. Covid-19 symptoms are cobra snake venom poisoning symptoms. The medical has been making synthetic snake venom for decades. And now we have Covid. Time for you to start putting 2 + 2 together.
In medicine, homeopathy is considered a pseudoscience that doesn't really do anything. Homeopathy uses extremely small quantities of various medicines and elemental substances to treat symptoms. Many people swear that it is effective, even though the medical considers it to be 'quack' medicine.
Fluoride in trace amounts is probably good for you.
