Zánět pod zubem: příznaky, příčiny a co s tím dělat

When you feel a persistent, throbbing pain under a tooth, it’s not just a bad toothache—it’s often a zánět pod zubem, infekce, která vzniká v kořeni zubu a šíří se do okolních tkání. Also known as zubní absces, it’s your body’s alarm system screaming that something’s seriously wrong inside. This isn’t something you can brush off with painkillers forever. Left untreated, it can spread to your jaw, neck, or even bloodstream—and that’s when things get dangerous.

Most zubní absces, lokální hromadění hnisu způsobené bakteriální infekcí v kořeni zubu starts with a deep cavity or a cracked tooth. Bacteria sneak in, infect the pulp, and eventually reach the tip of the root. That’s when the swelling, pressure, and pus build up under the gum. You might notice a pimple-like bump on your gum, bad taste in your mouth, or even swelling on your cheek. Sometimes, the pain comes and goes—but that doesn’t mean it’s gone. The infection is still there, quietly eating away.

Don’t confuse this with a simple gum irritation. A hnis v zubu, viditelný nebo skrytý hnis v oblasti kořene, který je přímým důkazem bakteriální infekce means the tooth’s nerve is dead, and the infection is spreading. You might feel pressure when biting, sensitivity to hot or cold, or even a fever. Some people think if the pain stops, the problem is solved. Wrong. When the nerve dies, the pain fades—but the infection keeps growing. That’s why many wait too long and end up needing surgery or even tooth extraction.

What you can do right now? Rinse with warm salt water to ease swelling, but don’t delay seeing a dentist. Antibiotics alone won’t fix it—you need to drain the pus and treat the source. That usually means root canal therapy or extraction. And if you’ve had a recent tooth extraction and now have swelling or pus, that’s zubní infekce, komplikace po vytržení zubu, která vyžaduje okamžitou léčbu. It’s not rare, and it’s not normal.
