Every morning and night, billions of people perform a simple ritual: they pick up a toothbrush. It's an unassuming tool, barely noticed in our daily routines, yet behind its humble bristles lies 5,000 years of innovation, a battle against disease, and engineering genius that revolutionized human health.
Why the Toothbrush Matters?
- The Great Equalizer: From ancient Egyptian pharaohs to astronauts on the ISS, toothbrush are universal.
- Silent Lifesaver: Gum disease links to heart conditions, diabetes, and dementia. Brushing isn't just about smiles, it's about survival.
- An Engineering Marvel: What looks like "just plastic and nylon" hides materials science, ergonomic and microbiology.
