How Long Until A Tooth Infection Kills You

how long until a tooth infection kills you

When we talk about keeping our teeth healthy, we often think about having a nice smile or avoiding cavities. But there’s a more serious side to dental health that we don’t talk about as much: tooth infections. A big question that we need to ask is: how long does it take for a tooth infection to become really dangerous?

What is a Tooth Infection?

First, let’s understand what a tooth infection is. It happens when bacteria get inside the tooth, where the nerves and blood vessels are. This can happen if you have a cavity that’s not treated, an injury, or after some dental treatments. The infection can stay in the tooth or spread to the areas around it and even to other parts of your body.

Signs of a Tooth Infection

The signs that you might have a tooth infection include a really bad toothache, feeling pain when you eat or drink something hot or cold, swelling in your cheek, swollen neck glands, bad breath, and sometimes a fever. If you notice these signs, it’s important to see a dentist right away.

How Fast Can It Get Serious?

The big question is: how long can you wait before a tooth infection becomes a life-threatening emergency? It’s hard to give a specific time because it depends on things like how strong your immune system is, how bad the bacteria are, and if you leave the infection untreated.

Sometimes, the infection can spread fast, causing swelling that can block your breathing or spread to your brain, which is really serious. Other times, it might get worse more slowly but still lead to big problems like an infection in your blood.

The Danger of Waiting Too Long

It’s hard to say exactly how long you can wait before a tooth infection becomes super dangerous. But what we do know is that waiting too long to get it treated is risky. In the worst cases, untreated tooth infections can lead to really serious conditions that can even be deadly if not treated quickly.

Your Health Matters

Your overall health also affects how quickly a tooth infection can become dangerous. People with weaker immune systems, like those with diabetes, HIV/AIDS, or cancer, are more likely to have the infection spread quickly.

Stopping It Before It Starts

The best way to deal with tooth infections is to prevent them and get them treated early. Regular dental check-ups, taking good care of your teeth, and getting dental problems fixed right away are important. If you think you have a tooth infection, go to the dentist as soon as you can to stop it from getting worse.


In short, it’s hard to say exactly how long it takes for a tooth infection to become really dangerous, but the longer you wait, the riskier it gets. Tooth infections are serious and need quick attention. Remember, keeping your teeth clean and going to the dentist regularly are the best ways to avoid these dangerous infections. If you think you might have a tooth infection, don’t wait – go see a dentist right away. It could be more important than you think!
