the infection in a tooth abcess can get into your bloodstream and cause problems all through your body!

A tooth abscess can cause a sinus infection, chest infection and cold or worse depending on how bad it is. Get to a dentist!

king Tut died of a tooth abcess, I swear I'm telling you the truth!! Ok as It was told to me. that's what happened to King Tut Ankh Amen and he died at 19 y.o. .... Mild case scenario is abcess tooth having to have root canal, followed by extraction. ...

Well, yes and no.

They don't cause the secondary infection, but they make you much more susceptible because your immune system is already overloaded in that area and the tissue in that area is already inflamed.

A tooth abscess can cause a sinus infection as some roots are long enough to grow into a sinus cavity. When you have an infection that is left untreated, it compromises your immunity level to being able to fight infections.

Yup and even death. It was on the news. A little boy died from it. I myself had to rinse with peroxide for a long time to get the infection from my tooth to heal and to get the sinus infection to go away.

It probably wouldn't cause chest infections as those are usually bacterial or viral. It might be possible for the infection to spread to the sinus cavity...Colds are caused by viruses.
What I can tell you is that an untreated dental abcess can kill you if it's left untreated. If you have one now, I'd go to the dentist ASAP!

Yes some tooth infections can 'travel' , causing problems in sinuses, and even your heart [ start flossing, people! ]
We had a 12 year old boy in the DC area recently die from complications of a tooth abscess.
The reverse normally does not happen.

Infections in the sinuses can involve teeth and gums, your respiratory system, your ears, everything...it's all connected and there are no partitions in our body to prevent an infection from penetrating from one system to another. There is even evidence that people who have tooth and gum problems have a greater chance of having heart disease as well. A generally healthy person does have antibodies that go into action to fight infection, but sometimes your body gets overwhelmed and your immune system is not up to the task of wiping out an infection on its own. That's when you need to see a dentist or a doctor, who can prescribe antibiotics to help your system fight infection.

Yes, it can also be fatal.
