Zánět zubního nervu: příznaky, příčiny a co s tím dělat

When you feel a sharp, throbbing pain in your tooth that won’t go away with painkillers, it’s often not just a cavity—it’s zánět zubního nervu, inflamace nervu uvnitř zubu, která vzniká, když bakterie proniknou až do zubního můstku. Also known as pulpitida, it’s the body’s reaction to an infection that’s already spread beyond the enamel and dentin. This isn’t something you can brush off. If left untreated, it leads to abscesses, bone loss, or even tooth loss.

What causes it? Usually, kariés, prohlubující se zubní kaz, který postupně ničí sklovinu a dentin that’s ignored for too long. But it can also come from a cracked tooth, a failed filling, or even trauma—like biting down on something hard. The zubní nerv, soubor nervů a cév uvnitř zubu, který poskytuje citlivost a života zubu doesn’t have room to swell. So when it gets inflamed, pressure builds up inside the tooth, and that’s what makes the pain so intense—especially at night or when you bite down.

Don’t confuse it with a simple toothache. A regular ache might go away after a few hours. A zánět zubního nervu gets worse. It might start as sensitivity to hot or cold, then turn into a constant, dull throb. You might feel it in your jaw, ear, or even temple—because nerves don’t always signal where the problem really is. Some people think it’s a sinus issue, others blame stress. But if the pain lingers for more than a couple of days, it’s not going away on its own.

And here’s the catch: you might not feel pain at all. Sometimes, the nerve dies quietly. The pain stops—but the infection doesn’t. That’s when you get swelling, pus, or a bad taste in your mouth. By then, it’s too late for a simple filling. You’ll need a root canal, or worse—a tooth extraction.

That’s why early detection matters. If you’ve had a deep filling and now your tooth feels different—tighter, more sensitive, or just "off"—don’t wait. If you’ve had a tooth hurt for more than a week, even if it’s not screaming, get it checked. A simple X-ray can show if the infection has reached the root tip. And modern dentistry can save the tooth in most cases—without pulling it.
