Abrasivita zubních past: co to je a jak ovlivňuje vaše zuby

When you brush your teeth, you might think the harder you scrub, the cleaner they get. But what if the real problem isn’t how you brush, but what you’re brushing with? abrasivita, míra drsnosti zubní pasty, která určuje, jak agresivně odstraňuje plak i části skloviny. Also known as abrazivita, it’s a hidden factor that can wear down your enamel over time—even if you’re brushing twice a day. Most people don’t realize that some whitening or "deep cleaning" pastes are basically sandpaper for your teeth. They remove stains, yes—but they also remove your natural protection.

It’s not just about the paste. zubní kartáček, nástroj, který spolu s pastou vytváří mechanické tření. Also known as čisticí nástroj, it plays a key role in how much damage gets done. A stiff brush with high abrasivity paste? That’s a recipe for receding gums and sensitive teeth. You don’t need to scrub like you’re cleaning a pan. Gentle pressure with a soft brush and low-abrasivity paste does the job better—and lasts longer.

And here’s the thing: poškození skloviny, trvalé opotřebení vrchní vrstvy zubu, které není možné obnovit. Also known as eróze skloviny, it’s silent, irreversible, and often unnoticed until it’s too late. You won’t feel it happening. No pain. No bleeding. Just gradually thinner enamel, more sensitivity to hot and cold, and a duller smile. Many people blame coffee or wine for staining, but the real culprit might be their daily toothpaste.

Look at the RDA value on the tube—Relative Dentin Abrasivity. Anything above 100 is risky for daily use. Most dentists recommend staying under 70. You don’t need whitening agents that feel gritty. Regular fluoride paste with low abrasivity works better for long-term health. Even if your teeth look stained, aggressive pastes won’t fix it—they’ll make it worse. Professional cleaning removes stains safely. At home, focus on prevention, not scrubbing.

The posts below show how abrasivita connects to everything from veneers and whitening to plaque control and gum health. You’ll find out which pastes actually help, which ones hurt, and how to pick one that protects instead of destroys. No marketing hype. Just what works—and what you should avoid.
