Does your toothbrush have a pattern of blue bristles weaved within the white ones? It makes the toothbrush look a lot more stylish, but these have a practical purpose most people don’t know about.
The blue dye is designed to wear off, and it’s usually at about the same time as when you should replace your toothbrush. Granted, you should be replacing your toothbrush every 3 to 4 months, but at least you have a handy reminder in case you lose track.
