Do some countries not brush their teeth?

Do People Everywhere Brush Their Teeth?

It might surprise you, but not everyone brushes their teeth every day — and in some places, many people don’t brush at all. While toothbrushing is a routine part of daily life in much of the world, global habits vary widely. According to recent data, only 45 out of the 72 countries and territories studied reported that more than 90% of their populations brush at least once a day. That means in over a tenth of the regions examined, a significant portion of people rarely or never pick up a toothbrush.

This isn’t just about personal preference — access to oral healthcare, cultural norms, and education all play a role. In wealthier nations, brushing is often reinforced from childhood, supported by widespread availability of toothpaste and dental care. But in low-resource settings, even basic hygiene items can be out of reach. In some communities, traditional methods like chewing sticks or saltwater rinses are still common, offering some dental benefits but not always replacing modern brushing habits.

What’s more concerning is the health impact. Poor oral hygiene is linked to gum disease, tooth decay, and even broader issues like heart disease and diabetes. When entire populations lack consistent brushing routines, public health systems feel the strain. Organizations like the World Health Organization have started pushing for better oral health education, especially in regions where brushing is uncommon.

Still, progress is possible. Simple interventions — like school-based brushing programs or affordable toothpaste distribution — have shown promise in changing behaviors. The truth is, brushing your teeth might seem like a small act, but globally, it reflects much larger stories about inequality, culture, and access to care. As awareness grows, so does the chance for change — one toothbrush at a time.
