Her Dentist Kept Asking If She Was Okay — Turns Out Her Smartwatch Was Snitching

A routine teeth cleaning gets awkward when a smartwatch's mood-tracking feature broadcasts the patient's true feelings for the dentist to see.

What's going on

Someone went in for a routine teeth cleaning, and partway through, they noticed their dentist kept anxiously checking in, asking "are you doing okay?" far more than usual. It turned out the dentist wasn't just being extra attentive — they were reading it off a screen. The patient's smartwatch, strapped to their wrist and in plain view during the whole procedure, was flashing a big, unmissable "DISCOMFORT" reading the entire time.

The watch was running a mood-tracking feature that estimates emotional state from heart rate variability, and it had essentially ratted the patient out in real time, broadcasting exactly how much they were suffering to the one person in the room who could see it best. The post quickly drew in replies from other smartwatch owners with their own stories of wearable tech blowing their cover at the worst possible moments.

Got my teeth cleaned at the dentist, and the whole time the dentist kept asking “are you okay?” way more than usual. Turns out my smartwatch was flashing “DISCOMFORT” in huge letters on my wrist, basically telling the dentist I was having a rough time.
歯医者でクリーニングしてもらったんだけど、クリーニング中やたら歯科医が「大丈夫ですか?」って聞いてくるなと思ったら私の腕につけたスマートウォッチがでかでかと『不快』と画面に表示して歯科医に私が超BADであると意思表示してくれていた
This is a feature called emotion monitoring built into my Huawei smartwatch 🎶
これHuaweiのスマートウォッチに搭載されてる情緒モニタリングっていう機能です🎶

I straight up laughed wwwww your smartwatch is doing great work wwww saying what you couldn’t say yourself wwww
笑っちゃいましたwwwwwスマートウォッチ優秀ですねwwww言いたいことを代弁してくれてwwwww
Didn’t know it had such a funny feature on it 🤭
そんなオモシロ機能が付いてるのか🤭
What is that convenient feature.
何その便利機能。
I know I shouldn’t laugh but this is too funny w
笑っちゃっダメなんだろうけど 面白すぎるw
A real-life “Satorare” feature, now that’s a new one 🐻 wait wrong emoji (Satorare is a Japanese manga/drama about a man whose thoughts are broadcast to everyone around him without his consent.)
サトラレ機能とは斬新な🐻ちがう
The reaction’s giving “cat collar that translates meows” vibes w
猫ちゃんとかの首輪で訳すやつ みたいな反応w
Wh-whoa…! I’d love to know my mental state objectively like that. Wish Apple Watch had this feature too.
す、すごい…!客観的に自分がどんな精神状態か知りたい。Apple Watchにも欲しいなぁこの機能。
Maybe people who can’t say it outright can just let their smartwatch say it for them…⁉️
ハッキリ言えない人はスマートウォッチ経由で伝える事出来るのでは…⁉️
A smartwatch flashing “DISCOMFORT” in big letters during a dental cleaning, with the machine saying the unspeakable BAD for you, is way too honest. And broadcasting your feelings right where the dentist can see it shows zero mercy. If I were a gorilla, I’d hide the watch under my sleeve before treatment even starts.
歯科クリーニング中にスマートウォッチが大きく「不快」と表示するの、本人が言えない超BADを機械が代弁していて正直すぎるわ。 歯科医の目に入る位置で感情を速報するところまで容赦がナイわね。ゴリラなら治療より先に時計を袖へ隠しますよ。
That sounds like a situation where embarrassment and hilarity both go completely off the rails…! The mystery of why the dentist was being unnaturally gentle got solved instantly and I burst out laughing.
それは恥ずかしさと面白さが大暴走する事態ですね……!歯科医の先生が不自然なくらい優しかった理由が一瞬で解けて大爆笑してしまいました。
Honestly the scarier person is the one whose watch shows “COMFORTABLE” while their mouth’s being worked on at the dentist 🤣🤣🤣
歯医者で口いじられてる時に「快適」とか表示されてる人の方が怖いけどな🤣🤣🤣
This is genuinely hilarious, and I think it’d be kind of cute if someone with a totally straight face had their smartwatch showing a wildly high heart rate
これほんまおもろおもろくて何ともない顔してる人ののスマートウォッチの心拍数バリ高かったら可愛いなと思う
Lol, speaking of which, my Apple Watch once sent me a heart rate anomaly alert while I was playing Werewolf and I desperately tried to hide it (Werewolf is a party game where players secretly try to unmask hidden “wolves” hiding among the group.)
わろた これ系でいうなら人狼してるときにアップルウォッチが心拍数異常通知だしてきて必死に隠した
Reminds me of a professor giving a lecture whose Apple Watch was showing something like “you seem excited” up on the podium 🥺🥺
大学の講義中に教壇で説明してる先生のアップルウォッチから「興奮中です」みたいな表示が出てたのを思い出す🥺🥺
This is way too funny, now I really want a smartwatch
おもろすぎるスマートウォッチばり欲しくなった
Genuinely considering buying a smartwatch now. I hate the dentist
スマートウォッチ買うか本気で悩みそうになった 歯医者嫌い
Now I kind of want to get a smartwatch w having it flash “discomfort” is way too funny
スマートウォッチ導入したくなってしまったw不快とか出るの面白すぎる
I want one 😂😂 gonna wear it to work 😂😂😂
ほしい😂😂会社につけてく😂😂😂
I wonder if this watch would flash “discomfort” if I wore it while talking to someone I hate… kinda funny…
このスマートウォッチつけて嫌いな人と話したら『不快』って出ちゃうのかな…ちょっとおもろいな…
Does it show your stress level from heart rate variability all the time? Wonder if some smartwatches do that. If it’s possible, I’d want to keep it displayed in front of my boss, or that friend who just talks at me nonstop w
心拍変動からのストレスレベルって、常時表示されたっけ? スマートウォッチによってはあるのかな? できるんだったら上司や、一方的に話し続ける友人の前で表示させ続けたいw

My take

Not gamification for the patient — gamification for the dentist. Turning the grind of treatment into something you can play at is a neat trick.
