Does A Tooth Infection Make You Tired?

A tooth infection might seem like a small problem, just affecting one part of your mouth, but it can actually have a big impact on your whole body. If you don’t get treatment for a tooth infection, it can make you feel really tired and sick, and it can lead to even bigger health problems. It’s important to know how a tooth infection can affect more than just your tooth because taking care of your teeth is a big part of keeping your whole body healthy. When a tooth infection spreads, it can cause a lot of trouble, not just in your mouth but all over your body. That’s why understanding tooth infections and how serious they can be is really important for keeping yourself healthy.

Does A Tooth Infection Make You Tired?

Yes, a tooth infection can make you feel really tired. Think of it like this: when you have an infection in your tooth, your body has to fight hard against the germs causing the infection. This fight takes a lot of your body’s energy, which can make you feel worn out or exhausted. The germs, or bacteria, in your tooth can create harmful substances called toxins, and these toxins can make you feel even more tired.

Since your immune system is working so hard, your body uses a lot of energy, and that’s why you might feel really tired or weak. It’s like when you spend all day running around and playing; by the end of the day, you’re super tired because you’ve used up all your energy. That’s what happens inside your body when it fights an infection.Getting the right treatment for the infection can help you feel better and less tired because it takes the pressure off your body’s immune system.

Can Tooth Infection Make You Feel Unwell? 

Yes, a tooth infection can make you feel unwell. Apart from the local symptoms like pain and swelling in the affected area, a tooth infection can lead to a handful of symptoms such as: 

  • Pain in the affected tooth or area: This can range from a dull ache to sharp, intense pain
  • Fever: A tooth infection can cause a fever as the body tries to fight off the bacteria
  • Headaches: The pain and pressure from the infection can lead to headaches
  • Bad taste in the mouth or bad breath: Infections can cause a foul taste or breath due to the bacteria and pus
  • Swollen lymph nodes in the neck: The body’s immune system may react to the infection by enlarging the lymph nodes
  • Fatigue or feeling generally unwell: The body’s effort to fight the infection can lead to overall tiredness or a feeling of malaise

All these are possible symptoms you can be experiencing because of a tooth infection. It is important to see a dentist if you are experiencing these symptoms. 

How Do You Know If a Tooth Infection is in Your Bloodstream?

Knowing whether a tooth infection has spread to your blood is super important. When a tooth infection gets really bad, it can move into your blood and make you very sick. This serious condition is called sepsis, and it needs quick medical help.

Here are some signs that a tooth infection might have spread to your bloodstream:

  • High fever: If your temperature goes way up, it’s a sign that your body is fighting hard against a serious infection.
  • Chills: Feeling very cold and shivery, even when you’re wrapped up, can be a clue that something’s wrong inside your body.
  • Fast heartbeat: When your heart starts beating faster than usual, it’s because your body is under stress from fighting the infection.
  • Feeling really sick: If you start to feel extremely unwell, way more than just a regular toothache or cold, it could mean the infection is spreading.

Sepsis is when the infection gets into your blood and starts affecting your whole body. It’s like the infection from your tooth is no longer just in your mouth; it’s now a problem everywhere in your body. This can make you feel very sick and need help from doctors right away.

When a tooth infection spreads to the bloodstream, it doesn’t just stay in one spot. It can affect many parts of your body and make you feel ill all over. That’s why it’s so important to get to a dentist or doctor if you have signs of a bad tooth infection. They can check if the infection has spread and get you the right treatment to make you better.

How Long Does it Take for a Tooth Infection to Make You Sick?

When you get a tooth infection, how quickly it makes you feel sick can be different for everyone. Some people might start feeling bad just a few days after the infection starts, while others might not feel sick until much later. There are a few things that can change how fast you get sick from a tooth infection:

First, it depends on how bad the infection is. If it’s a really strong infection, you might start feeling sick pretty quickly because the germs are spreading fast and causing a lot of problems. But if the infection is not so severe, it might take longer for you to feel really sick.

Another important factor is whether you get treatment for the infection. If you go to the dentist right away and start treatment, you might not get as sick, or you might get better faster. But if you don’t get the infection treated, it can get worse over time and make you feel sicker.

There’s no exact time for when a tooth infection will make you sick. It really depends on how bad the infection is, how your body deals with it, and if you get the right treatment. That’s why it’s so important to see a dentist if you think you have a tooth infection, so they can help you before it gets worse and makes you really sick.

How Long Can a Tooth Infection Go Untreated?  

When a tooth infection will make you feel sick isn’t set in stone. It varies based on the infection’s severity, your body’s ability to fight it, and whether you get treatment. If the infection is severe, you might get sick quickly. But with a milder infection or strong immune response, it might take longer to feel the effects.

Getting the right treatment plays a big role, too. If you treat a tooth infection early, you might avoid getting very sick, or you could recover faster. On the other hand, if you ignore the infection, it could get worse and make you much sicker over time.

That’s why going to the dentist as soon as you suspect a tooth infection is crucial. A dentist can assess the situation and start treating the infection early, helping you avoid more serious health problems. The key is to not wait until the infection gets bad because the sooner you get help, the better your chances are of avoiding serious illness.


Taking care of your teeth is super important because a tooth infection can make you feel really sick and affect your whole body. If you think you have a tooth infection, don’t wait around hoping it will go away on its own. The sooner you see a dentist, the better. They can find out what’s wrong and fix it before it gets worse. Remember, keeping your teeth healthy helps keep your whole body healthy too.
