      When Your Dentist Uses ChatControl Logic</h1>
    <p>
      So there I am, sitting in the waiting room with a mildly annoying
      toothache. Nothing catastrophic, just one of those dull throbs
      that tells you something's going on in there that could turn nasty
      if ignored. The receptionist calls my name, and I walk into Dr.
      ChatControl's office.</p>
    <p>
      Dr. ChatControl greets me with a concerned expression. "I've
      reviewed your case," he says gravely, "and many others. Toothaches
      are a serious problem. Did you know that in 2023 alone, at least
      101,988 people in Europe experienced dental pain? That's over 60%
      of all global dental complaints traced to this region."</p>
    <p>
      "Okay," I say. "But I just need you to look at this one tooth"</p>
    <p>
      "This is an epidemic," he interrupts. "And we can't just treat
      symptoms anymore. We need a comprehensive, mandatory risk
      assessment."</p>
    <p>
      Dr. ChatControl pulls out a 47-page questionnaire. "First, we
      assess the risk that your mouth might develop cavities, gum
      disease, or oral cancer," he explained. "This applies to everyone,
      regardless of whether they have symptoms."</p>
    <p>
      "But I have symptoms," I sigh. "That's why I'm here."</p>
    <p>
      "Exactly!" he says triumphantly. Which means you're high-risk. So
      we move to Phase Two: mitigation measures."</p>
    <p>
      He hands me a pamphlet titled <em>
        Safety-by-Design for Oral Health</em>
      . "From now on, you'll need to implement parental controls on your
      diet. Every candy will come with an age verification wrapper and
      user reporting mechanisms. so your teeth can flag potential
      problems, and verify your age before consuming any hard foods."</p>
    <p>
      "I'm 38," I retort.</p>
    <p>
      "Perfect," he replies. "That means you're old enough to consent to
      monitoring."</p>
    <p>
      "Now," Dr. ChatControl continues, "since your mitigation measures
      haven't been implemented yet because you just got here - I'm
      authorized to issue a detection order." He holds up an
      official-looking document with a judge's signature. "This allows
      me to scan not just the tooth that hurts, but your entire mouth.
      Also your sinuses. And your lymph nodes. And, just to be thorough,
      everyone in the waiting room."</p>
    <ul>
    </ul>
    <p>
      "Wait, what?" I blurt out.</p>
    <p>
      "It's targeted," he assures me. "We're only scanning high-risk
      areas—which, according to our independent EU Dental Centre, is
      every tooth, every patient, all the time."</p>
    <p>
      "But here's the clever part," Dr. ChatControl says, pulling out
      what looks like a tiny sander strapped to an airbrush.</p>
    <p>
      "Well, your enamel contains layers that currently block our view
      with regards to early detection of certain viruses. So we need to
      replace the enamel with an optimized layer that perfectly protects
      against currently known sugars and acids but allows our government
      approved detection equipment to inspect the content of your
      teeth."</p>
    <p>
      I' flabberghasted. "You want to weaken my enamel?"</p>
    <p>
      "Only slightly!" he said cheerfully. "Just enough so that our
      scanner can monitor what's happening inside your teeth at all
      times. Don't worry,the new enamel will still protect you from
      everything else."</p>
    <p>
      "How's that possible if you can penetrate it?", I continue, still
      cautious.</p>
    <p>
      "Well, factory approved candies, for example," he says. "Reputable
      candy manufacturers have agreed to respect the adapted enamel and
      not penetrate it. They've signed a treaty to use optimized
      sugars."</p>
    <p>
      "And the artisanal candies?" I asked.</p>
    <p>
      "Ah," he said, adjusting his glasses. "Well, those are obviously
      illegal! Those criminals don't tend to honor treaties. So yes, the
      adapted enamel will make your teeth more vulnerable to
      unauthorized cavity formation, bacterial attacks, and anyone who
      wants to exploit the fact that your natural protection has been
      replaced with a see-through version."</p>
    <p>
      "So you're making my teeth less secure," I repeat.</p>
    <p>
      "We're making them more observable," he corrects, with a slightly
      annoyed tone. "There's a difference. Your teeth will still be
      protected, just not from us. Or hostile foreign candy shops. Or
      those criminal artisanal real-sugar-nuts. But you have no business
      there anyway. But they definitely protect against harms from
      law-abiding candy!"</p>
    <p>
      "But... Over 500 leading dentists signed a letter saying this
      would create massive vulnerabilities", I point out.</p>
    <p>
      "Those dentists aren't thinking about long term dental hygiene."
      Dr. ChatControl sighs dismissively. "Besides, it's not a backdoor
      if we're replacing your front door with a tinted glass door given
      all our citizens are law abiding!"</p>
    <p>
      His tone gets sterner if he continues: "Let me say more, If you
      refuse to upgrade your enamel, we will consider you a risk of
      dental terrorism. This no longer is about only your teeth, you
      must know. If you choose to blatantly ignore your teeth, you are a
      threat to society!"</p>
    <p>
      "But... The whole reason I am here, is because I care about my
      teeth..."</p>
    <p>
      The docter holds up his machine and asks: "Do you want me to treat
      you or report you?"</p>
    <p>
      Oh, whatever, it seems everybody is doing this. I don't want to be
      the outcast crying wolf all the time. So I cave in. The procedure
      doesn't feel painful, so that's a relief.</p>
    <p>
      After completing the baseline scan, Dr. ChatControl frowns at the
      screen: "This is concerning," he says. "The system has flagged
      8,412 potential cavities."</p>
    <p>
      "But I only have 32 teeth," I wimper.</p>
    <p>
      "The detection algorithm works on a probabilistic model," he
      explains. "Swiss dental authorities report that about 80% of
      automated cavity reports are false positives, so we'll need to
      investigate all of them."</p>
    <p>
      "That still means 1,682 of those threats are real", I sigh.</p>
    <p>
      "Which is still 1,682 too many!" Dr. ChatControl blurts. "Now,
      I'll need to drill exploratory holes in every tooth, in your gums,
      your tongue, and —just to be safe— your neighbor's mouth, because
      the system flagged them too when they walked past the waiting
      room."</p>
    <p>
      "This seems insane," I say.</p>
    <p>
      "The math is solid," he insists. "Even at 99.999% accuracy —which
      doesn't exist— we'd still generate 100,000 false dental alerts per
      day across Europe's 450 million people. But we can't let cavities
      win."</p>
    <p>
      While Dr. ChatControl explains his flawless system, I notice how
      the tooth that actually is hurting —the one I came in to fix— is
      starting to abscess.</p>
    <p>
      "Uh, Doctor," I say, pointing to the swelling.</p>
    <p>
      "We'll get to that after we finish scanning everyone," he says
      dismissively. "The important thing is that no cavity goes
      undetected, even if that means we spend all our time investigating
      healthy teeth."</p>
    <p>
      "But the actual problem is getting worse," I said.</p>
    <p>
      "That's because sophisticated cavities have learned to evade
      detection," Dr. ChatControl explains. "They change their
      appearance slightly —maybe grow on the back of the tooth instead
      of the front, or hide under existing fillings. Our algorithms
      can't catch those."</p>
    <p>
      "What about that letter from those 500 dentists? They also claim
      this detection method is technically infeasible." I try again.</p>
    <p>
      "They're just not thinking big enough", the doctor blocks my
      argument.</p>
    <p>
      "So here's the treatment plan," Dr. ChatControl says, "We're going
      to install a permanent scanning device in your jaw that monitors
      every tooth, 24/7, and reports any suspicious activity to a
      centralized EU Dental Database."</p>
    <p>
      "That sounds like a massive security risk," I said.</p>
    <p>
      "Not at all!" he replied. "The device is encrypted. Only our
      scanners can look behind your upgraded enamel. What leaves your
      tooth, is already encrypted. No other device than ours, can read
      the data, so your privacy is intact."</p>
    <p>
      "So what about those knock-offs you can buy on Ali Express?" I
      ask.</p>
    <p>
      "Oh, but they don't work reliably. And also: Why would hackers
      want access to your teeth?" he scoffed.</p>
    <p>
      "Although, now that I think about it, the device itself would make
      a high-value target for malicious actors, Als they could abuse
      them to learn how to make knock-off candy that doesn't get
      detected by the scanners. Things your natural enamel obviously
      protects against. But let's not dwell on that."</p>
    <p>
      "By the way," Dr. ChatControl adds casually, "EU politicians and
      government officials are exempt from this scanning requirement
      under 'professional dental secrecy.'"</p>
    <p>
      "So their teeth don't get monitored?" I ask.</p>
    <p>
      "Correct," he says. "Their oral health is a matter of public
      trust. Yours, however, requires constant surveillance."</p>
    <p>
      "That seems like a double standard," I say.</p>
    <p>
      "It's a two-tier system for a two-tier society," he replies
      pleasantly. "Now, shall we proceed with installing the jaw
      monitor?"</p>
    <p>
      By this point, my actual toothache is developing into a full-blown
      infection. The pain is excruciating.</p>
    <p>
      "Doctor, I need antibiotics and a root canal," I cry.</p>
    <p>
      "We don't do targeted treatments anymore," Dr. ChatControl says.
      "That's the old model. Now we focus on comprehensive, mandatory
      monitoring."</p>
    <p>
      "But I'm going to lose the tooth," I say.</p>
    <p>
      "Perhaps," he acknowledges. "But while we were scanning everyone
      in the waiting room, we found three people with slightly
      suspicious molars! They're perfectly healthy now, but they could
      develop cavities someday. That's three potential problems
      prevented!"</p>
    <p>
      "But my actual problem isn't being prevented," I point out. "It's
      getting worse."</p>
    <p>
      "Well yes," he admits. "But we've invested so much in the scanning
      infrastructure that we can't really afford to do traditional
      dentistry anymore. The system needs to justify itself, you
      understand."</p>
    <p>
      "This is insane," I repeat.</p>
    <p>
      "This is <em>
        progress</em>
      ," he corrects me.</p>
    <p>
      As I' left 'm leaving the office —untreated, in pain, and with a
      jaw full of surveillance equipment— I notice a sign on the door: <em>
        "Signal Dental, Orthodontics Threema, and Proton Mouthcare have
        ceased operations in the EU due to incompatibility with
        mandatory scanning requirements."</em>
    </p>
    <p>
      Apparently, the dentists who actually know how to fix teeth
      without installing spyware have all moved to Switzerland.</p>
    <p>
      Meanwhile, I hear the voice of Dr. ChatControl behind me in the
      waiting room, announcing to everyone: "We've successfully detected
      6,847 potential cavities this week!" When someone asks what he
      means by potential, he quietly answers: "Only 11 were real, but
      that's 11 teeth saved!"</p>
    <p>
      The infection is still spreading and I'll probably loose my tooth
      after all because nobody actually is treating it. But at least the
      healthy ones are under constant surveillance.</p>
    <p>
      I made fun of it. But it's not funny. It's about wasting loads of
      money on a noble goal in all the wrong ways. But next week the
      vote will be cast in the EU. So it's high time to reach out to
      your MEP and ask their stance if they are undecided or worse - are
      in favor. Go to fightchatcontrol.eu if you live in Europe.</p>
    <p>
      Oh, and if you don't live in Europe... This will also impact you.
      Because weakened encryption in mainstream products will most
      certainly spread.</p>
