When a tooth dies, it doesn’t mean it falls out right away — it means the nerve inside is dead. This happens when bacteria reach the mrtvý zub, zub, jehož nervová tkáň zemřela kvůli infekci, úrazu nebo hlubokému kazu. Also known as nekrózovaný zub, it may look normal from the outside, but inside, it’s a breeding ground for infection. Many people think a dead tooth doesn’t need attention because it doesn’t hurt anymore. That’s a dangerous mistake.
A mrtvý zub, zub, jehož nervová tkáň zemřela kvůli infekci, úrazu nebo hlubokému kazu often results from untreated zubní kaz, poškození zubní skloviny způsobené kyselinou vyráběnou bakteriemi or trauma. The infection kills the pulp — the soft tissue with nerves and blood vessels — and without treatment, bacteria spread to the kořenový kanál, kanál uvnitř kořene zubu, kde se nachází nerv a cévy. This can lead to an abscess, swelling, pain in the jaw, or even systemic infection. You might not feel anything at first, but over time, the tooth can darken, become loose, or start throbbing when you bite down.
That’s why endodoncie, léčba kořenového kanálu, která odstraňuje mrtvou tkáň a čistí infikovaný prostor is often the only way to save the tooth. It’s not just about removing pain — it’s about stopping the infection before it spreads to your bone or gums. Without it, extraction becomes inevitable. And even after treatment, you need to protect the tooth with a crown. A dead tooth is brittle. It can crack under normal chewing pressure.
Some people notice a bad taste or smell — that’s a sign of pus building up. Others see the tooth turning gray or dark yellow. If you’ve had a blow to the mouth or a deep filling years ago and now the tooth looks different, don’t wait. Get it checked. Early treatment saves money, time, and your natural tooth.
What you’ll find below are real, practical guides on how to recognize a dead tooth, what procedures can fix it, how to avoid ending up with one, and what happens if you ignore it. From symptoms you can spot at home to what your dentist will actually do in the chair — everything you need to know without the jargon.
