A recent study from England reveals that text message reminders can significantly enhance tooth-brushing habits among teenagers, especially those from low-income families.
Conducted by researchers from the University of Sheffield in partnership with universities in Cardiff, Leeds, York, and Dundee, the study evaluated a new initiative aimed at promoting better oral hygiene and reducing tooth decay among secondary school students.
The BRIGHT trial, published in the Health Technology Assessment, involved a classroom lesson combined with twice-daily text reminders about brushing teeth. The study examined 4,680 students across 42 schools in England, Scotland, and Wales. Although the overall effect on cavity prevention was not statistically significant, the program did positively influence self-reported brushing habits six months post-intervention.
The findings suggest that the initiative may particularly benefit students from low-income families, with some evidence indicating a reduction in tooth decay within this demographic.
Professor Zoe Marshman stated, “We conducted dental assessments on nearly 4,700 secondary pupils at the beginning of the study and again after two and a half years. Students who participated in the classroom lesson and received text reminders reported brushing their teeth more frequently after six months. However, they did not show a decrease in tooth decay or plaque levels after two and a half years. Notably, those eligible for free school meals appeared to experience greater benefits, indicating the program’s potential to address inequalities in oral health.”
