Treatments necessary: Decay, infected teeth and gums do not stay just in the mouth. The infection can go to your sinus, or anywhere via your blood stream. The infection is predominantly bacterial, but may include virus/fungus. You need to be properly diagnosed and then the infections need to be treated. Left alone, it will always get worse. Therefore, your answer is how it should be treated. Insurance doesn't car.

Yes: Yes. I routinely see sinus pain and headeaks from dental infections. As much as we want the disease causing bacteria to stay put in the mouth, the reality is they enter your blood and circulate your body. You constantl stress your body's immune system. Look at aaosh on internet. Overall body inflammation is increased (CRP) as well as inflame many other systemic probs. Check out spirochetes.

Serious infections: Untreated dental abscesses can be serious. Your entire immune. System is constantly fighting these infections. This can have serious implications on your heart, kidneys, lungs and the rest of your body. It is important to get dental care. If finances is a major concern seek care at a dental school if you have one close to you.

Yes, it is possible: A large enough oral infection that is left untreated or even a smaller infection in an immune compromised person can lead to complications that could cause death. Untreated oral infections, such as periodontal disease, have also been shown to increase the risk of heart attack and stroke in otherwise healthy people.
