YES !!! you are NOT paranoid,you are 100% on track.
Planned obsolescence is a fact of life in our mouths, if you had parents that could afford dental "care". I did, my siblings did not... I was youngest, and my parents got on solid financial feet by the time I was 5.
Every visit to the dentist resulted in drilling my enamel, and finding "three more fillings in about 6 months time to do". Allways.
I had 15 or more Amalgam
fillings by age 12. I had them all re-done , and more started, and so was over 50 Amalgams
by age 30.
Drilling the enamel is now illegal in Britian for people under 12 years of age. They use an OZONE ballon and it kills the cavity!!! This could have been done in the 1950s too, but it would not have ensured future business for all those "dentites". Drilling enamel of the youth does. Its really ugly business.
Black teeth mean they are dead. No roots, no blood flow, no nutrients to feed the teeth or fight infection. Dead teeth are a host for disease causing bacteria. root canals
are even better for bacteria to live in.
Your concern about toxins from braces is real too.
So is the "un-natural" designs of your ortho. My parents were, thankfully, too cheap to get that orthodontist stuff done on me, but the dentists did call for it [my teeth came in straight anyhow, lol].
Do you have chronic health problems? Do you believe you have a "mental illness" due to the condition of your mouth? I believe I do/did.
I am about to get the last teeth removed, full dentures. I had to fight them, even trick them, into getting extractions done, despite my wretched health problems from teeth.
They - doctors OR dentists - never did agree with my health assessment, and when I proved it to them by getting well, they asked me to leave and not come back!! Truth hurts, but my teeth hurt more.
Its the biggest health scam ever, and there are more victims than from all Terrorism
ever. What a devastating affect on our culture, our development personally and as a species. Its one of the worlds great crimes. Dentists get trapped - heavy debt, spending all that time in school, with parents and banks loaning you money that you must pay back, so they have to work, and cannot get a liscence unless they comply with dental association guidelines and propaganda.
No wonder dentists have the highest suicide rate of all professionals - have you heard that?
