Toothpaste: It's something most people use every day, but rarely give much thought to — except, perhaps, when choosing from among the dozens of brands that line the drugstore shelf. Is there any difference between them? What's toothpaste made of… and does it really do what it promises on the box? To answer those questions, let's take a closer look inside the tube.
The soft, slightly grainy paste that you squeeze on your brush is the latest in a long line of tooth-cleaning substances whose first recorded use was around the time of the ancient Egyptians. Those early mixtures had ingredients like crushed bones, pumice and ashes — but you won't find that any more. Modern toothpastes have evolved into an effective means of cleaning teeth and preventing decay. Today, most have a similar set of active ingredients, including:
Besides their active ingredients, most toothpastes also contain preservatives, binders, and flavorings — without which they would tend to dry out, separate… or taste awful. In addition, some specialty toothpastes have additional ingredients for therapeutic purposes.
What's the best way to choose a toothpaste? The main thing you should look for is the American Dental Association (ADA) Seal of Acceptance on the label. It means that the toothpaste contains fluoride — and that the manufacturer's other claims have been independently tested and verified.
But once you've chosen your favorite, keep this bit of dental wisdom in mind: It's not the brush (or the paste) that keeps your mouth healthy — it's the hand that holds it. Don't forget that regular brushing is one of the best ways to prevent tooth decay and maintain good oral hygiene.
