Zubní praskliny: co je to, jak je rozpoznat a co s nimi dělat

When you feel a sharp pain when biting into an apple, or notice a strange sensitivity to cold, it might not be a cavity—it could be a zubní praskliny, tenké trhliny ve sklovině zubu, které se často neukazují na rentgenu a přesto způsobují bolest. Also known as trhliny na zubech, they’re more common than you think, especially if you grind your teeth, chew ice, or have had large fillings. Many people ignore them, thinking it’s just a temporary twinge. But left untreated, these tiny cracks can grow, let bacteria in, and lead to infection—or even a broken tooth.

What causes them? It’s not just accidents. zubní sklovina, tvrdá vrstva, která chrání zub, ale není nezničitelná can weaken over time due to acid from soda, frequent snacking, or even brushing too hard. If you’ve had root canals or big fillings, your tooth is more vulnerable. And if you clench your jaw at night—bruxismus, nevolní stiskání nebo škrábání zubů, často bez vědomí—you’re basically hammering your teeth every night. The result? Microfractures that start small but get worse fast.

You won’t always see a crack with your eyes. But if you feel pain when you bite down and it goes away when you release, or if one tooth suddenly becomes super sensitive to hot or cold, don’t brush it off. A zubní lékař, odborník, který může pomocí speciálních nástrojů a osvětlení detekovat i nejmenší praskliny can spot them with a dye or special light. Some cracks are so fine they only show up under magnification. Waiting until it hurts constantly means you might need a crown—or worse, an extraction.

The good news? Many praskliny can be fixed early. A simple bonding or a crown might be all you need. But the key is catching them before they go deep. That’s why regular check-ups matter—even if nothing feels wrong. If you’ve had a recent trauma, notice a change in your bite, or just feel something’s "off" with one tooth, get it checked. It’s not about fear. It’s about catching problems before they cost you more time, money, and comfort.
