Colored Toothpaste
While most of us end up buying the classic three-stripe kind of toothpaste, we aren’t actually aware of the benefits and purpose behind each color. For some reason, the toothpaste companies don’t bother explaining it to us either, but the truth is, each color in your toothpaste tube has different ingredients that do different things.

For example, the white paste contains substances that remove plaque and as a result, whiten your teeth. The red stripe usually contains vital elements for proper gum care, and the blue paste holds the antimicrobial and breath-freshening components.
Toothpick Grooves
The next time you go out for Chinese or Japanese food, grab a few of their toothpicks. If they have well-defined grooves, then they’re likely a specially designed toothpick that allows people to use them in public without disregarding proper dining etiquette.

After you’re done digging chicken bits out of your teeth, simply snap off the top of the toothpick. The grooves are weakened, making this task rather easy, leaving you with a perfectly sized stand for your toothpick. It allows restaurant-goers to put their toothpick down without it touching the table after their plates have been cleared.
Blue Toothbrush Bristles
You might think the bristles on toothbrushes come in bright colors in order to be more appealing and fun for kids. However, these colors actually serve an essential purpose for users that few people know about. Over time, a toothbrush’s colored bristles will fade in brightness, indicating that it’s time to swap it out for a new one.

Most manual toothbrushes come equipped with this feature, and electric toothbrushes are just starting to catch up. Referred to as toothbrush indicators, they work by embedding a non-toxic dye into the outer layers of the bristles. This allows them to stand out by making them a different color from the rest. Often, blue dye is used, so be sure to take a look at your toothbrush and see if it’s time to swap it out!
