When you feel a sharp pain when eating something cold or sweet, and you can see a dark hole or crack in your tooth, you’re dealing with an otevřený zub, stav, kdy se zubní kaz dostal až k vnitřní části zubu a odhalil jeho citlivé vrstvy. Also known as rozpadlý zub, it’s not just a cosmetic issue—it’s a warning that your tooth’s nerve might be under attack. Many people think if it doesn’t hurt all the time, it’s not serious. But that’s when the damage is already done.
An otevřený zub usually starts as a tiny spot of decay, often hidden between teeth or near the gumline. Over time, bacteria eat through the enamel, then the dentin, until they break through to the pulp—the soft core with nerves and blood vessels. That’s when the pain kicks in. You might feel it when you bite down, when you drink cold water, or even when you breathe in cold air. It’s not just discomfort—it’s your body screaming that something’s wrong inside. If you ignore it, the infection can spread to the jawbone, cause swelling, or even lead to a zubní absces, which can affect your whole body.
What makes an otevřený zub so dangerous is how sneaky it is. You don’t always see it. Sometimes the hole is small, but the decay runs deep. That’s why regular checkups matter—even if nothing hurts. A dentist can catch it early with X-rays, before it turns into a root canal or extraction. And if you already have an open tooth, don’t wait for the pain to get worse. The longer you delay, the harder and more expensive the fix becomes. Some people try home remedies—saltwater rinses, clove oil, garlic—but those only mask the problem. They don’t fix the hole.
What you’ll find in the articles below are real, practical answers: how to tell if your tooth is truly open, what treatments actually work, why some fillings fail, and how to prevent this from happening again—even if you’ve already had a tooth treated. You’ll learn what to expect when you visit the zubní lékař, how to recognize early signs before the pain starts, and why ignoring a small dark spot can cost you a whole tooth. This isn’t about fear—it’s about knowing what to do before it’s too late.
