After two years of teaching, she still finds herself surprised watching her students brush their teeth together after lunch. β€œWhen you brush your teeth, you spit and sometimes bits of food come out. It’s not exactly something you want to show others,” she said. Back in Canada, this is considered a private actβ€”but in Korea, it’s totally normal!

It Starts From Childhood: Group Brushing in Schools

Korean kids learn to brush together from the moment they enter kindergarten or daycare! 🦷 Teachers guide children through group toothbrushing sessions in restrooms equipped with long sinks designed for this exact purpose. This daily routine continues throughout their school years. In 2016, over 100 schools across Seoul even installed special β€œtoothbrushing stations” with multiple faucets so students wouldn’t crowd regular restrooms!

The Habit Continues Into Adulthood

The public brushing habit doesn’t stop after graduation! πŸ’Ό In many Korean offices, you’ll see employees lining up to brush their teeth about 10-15 minutes before lunch break ends. Toothbrushes in plastic cases are casually left on windowsills and sinks. β€œJeon Ga-jung,” a 28-year-old office worker, says: β€œSince we eat lunch and grab coffee together, brushing our teeth together just feels natural. We’ll chat a bit while brushing.”

Toothbrush-Friendly Infrastructure Everywhere

Korea has built infrastructure for public brushing! πŸš‰ Highway rest stops have toothbrush vending machines. Study cafes in Noryangjin have dedicated β€œtoothbrushing zones” for students pulling all-nighters. Some department stores even have mouthwash dispensers built into restroom walls! Travelers at airports and terminals commonly wash up and brush after long trips. It’s everywhere!

The Famous β€œ3-3-3 Rule”

So WHY do Koreans brush so often? πŸͺ₯ In the late 1980s, the Korean Dental Association launched the β€œ3-3-3 rule” campaign: brush 3 times a day, within 3 minutes after eating, for 3 minutes each time. Professor β€œCho Hyun-jae” of Seoul National University explains that because of this shared understanding, toothbrushing became not just hygiene but β€œsocial etiquette.”

Blame It on Korean Food!

There’s another reason: Korean food! 🌢️ Korean cuisine often contains ingredients that stick to teeth like chili powder, or have strong odors like garlic. Professor Cho adds: β€œGiven that schools and workplaces emphasize group activities, brushing openly is seen as maintaining a good impression.” Even taxi driver β€œPark Sang-jin,” who’s worked in Gyeongju for 15 years, says brushing is β€œa gesture of respect toward passengers.” πŸ’œ
