Incheon's Michuhol-gu Public Health Center (Director Kim Young-ran) is continuing a program this year that lets students look after their oral health with the smartphones in their hands. The health center said Oct. 16 that it will run the "2026 Youth Oral Health Behavior Improvement Program" from Oct. 19 to 23 for 1,817 students at eight elementary and middle schools in the district.

The program uses near-field communication (NFC) technology. The health center will give every participating student an NFC key ring carrying oral health messages. When a student taps the key ring against a smartphone, one of 20 oral health care images appears on the screen at random. Because students cannot know in advance which image will appear, they tend to tag the key ring several times, seeing oral care information again and again in the process.
The content avoids textbook-style explanations. Each image draws on teenagers' daily lives and habits and is designed to be approachable, so that students take in health information naturally as part of their routines rather than "studying" it. The health center also plans to run a "Challenge! Healthy Mouth Habits" campaign alongside the program to boost student interest and participation.

The biggest change in this year's program is its target group. The program, previously open only to middle school students, has been expanded to include sixth graders in elementary school. The move is seen as aimed at helping students develop the habit of caring for their own oral health before they enter middle school.
The program builds on the NFC-based youth oral health program the health center first introduced last year. Students tagged their key rings steadily from the first year, with cumulative tags surpassing 35,000. Recognized for this level of participation and for its approach differing from conventional health education, the health center received an excellence award at the "2025 Second-Half Proactive Administration Contest."

To keep up the enthusiasm seen in the first year, the health center has replaced the content linked to the key rings this year. Students who took part last year and already received a key ring can view the new images with the key ring they already have, without needing a new one. Notably, by reusing items already distributed and updating only the content, the approach reduces the burden of continuing the program.

"It is important to create an environment where young people do not simply learn about oral health but repeatedly pay attention to it in daily life and put it into practice on their own," an official from the Michuhol-gu Public Health Center said. "We will continue to pursue participatory oral health programs that reflect the characteristics and lifestyles of young people."
The program is significant as an attempt to build health habits through repeated exposure in daily life rather than one-off education. Attention is on whether the approach, tailored to young people accustomed to using smartphones, can draw as much participation this year with its expanded target group as it did in its first year, and whether it will spread to other youth health programs.
