Dad 3D-Printed a Tooth-Shaped Toothbrush Holder. His Daughter Gave It Cavities.

What's going on

A father used his 3D printer to make a tooth-shaped toothbrush holder at his daughter's request. It came out clean, white, and anatomically charming — a neat little molar sitting on the bathroom shelf. Then his daughter got to it with a black marker and filled the holes with scribbles, turning the pristine tooth into a cavity-riddled wreck.

The dad posted a photo online, and the replies immediately appreciated the daughter's vision. Whether she intended a dental health PSA or just thought the holes were begging to be colored in, the result is arguably a more effective toothbrush holder than the original.

Made a tooth-shaped toothbrush holder on my 3D printer at my daughter’s request… and she went and gave it cavities with a marker.

娘のリクエストで3Dプリンターで、歯の形の歯ブラシ立てを作ったら、マジックで塗られて虫歯にされてた…。

Actually a great design for reminding you to brush your teeth…

これは歯磨きしなくっちゃ、と思うよいデザイン…

Adorable lol. Paint it gold and fight back with a gold tooth!

可愛いww 金色に塗って金歯にして対抗しましょう！

This is genuinely too good as a design lol

デザインとして優秀すぎるｗ

I mean, there ARE holes in it, so the urge to make it a cavity makes total sense lol

そりゃ穴空いてるなら虫歯にしたくなるのは分かるｗ

The level of decay though 😱 She went all the way to the root 💦💦

虫歯のレベルが😱 奥まで行ってますね💦💦

This needs root canal treatment and root separation… take care of yourself 😂

根管治療してルートセパレーションが必要です…お大事に😂

Well, there are holes in it… she probably also wanted to make the edges more visible.

まぁ、穴開いてるしな… 穴のふちを目立たせる意味もあったんだろうけど

I mean technically yes holes = cavities so fair enough www dying laughing www

確かに穴空いてるから虫歯だけどwww めっちゃお腹痛いwww

This could literally win a prize as a school science project.

自由研究にしたら入賞しそうなレベル

So every time you stand at the sink, it’s a reminder: this is what happens if you don’t brush.

歯磨きしないとこうなるぞ、と洗面所に立つたび思うわけか…

But honestly, looking at this, you’d actually feel motivated to brush.

でも、この方が、マズイと思って磨きますね

She already knows the word “lesson” (戒め)? 😂

戒めという言葉を既に知っているのか😂

「戒め」(いましめ / imashime) means “warning” or “moral lesson” — a rather weighty concept for a kid with a marker.

I can feel my toothbrushing motivation rising メキメキ

歯磨き意欲の高まりをﾒｷﾒｷﾞ感じる

Kind of like memento mori…?

メメントモリ的な…？

Memento Caries — remember the cavity. (A play on “memento mori,” the Latin phrase meaning “remember you must die” — here repurposed as “remember you must brush.”)

メメント・カリエス（虫歯を忘るるなかれ）

“メメント・カリエス” combines memento mori (Latin: “remember death”) with caries (the medical term for tooth decay), meaning “remember the cavity.” The joke is that the holder now functions as a tiny bathroom skull.

All I can see is Altaria. (Altaria is a Cloud/Dragon-type Pokémon with a round white fluffy body — apparently not so fluffy once a kid gets to it.)

チルタリスにしか見えない

A sick Altaria.

病気のチルタリス

Because of Pikachu (probably a yellow toothbrush), now it looks like a grubby Altaria.

ピカチュウのおかげで薄汚れたチルタリスに見えてしまった。

Altaria.

チルタリス

My take

3D printing something clever is impressive enough, but the daughter's instinct to immediately stress-test it with a marker is the real engineering spirit. Also, the fact that the improvement was basically instant.
