Bacteria got into the nerve canal of the tooth and as the nerve dies, gases build up inside the tooth. They have no place to go but out through the only opening in the tooth which is the end of the root. As it drains it eats away at the bone and create a pool of infection that over time usually shows up as a dark circle on an x-ray.
The infection into the nerve is usually caused by trauma to the tooth that doesn’t break it (one time hit or continued grinding or clenching), a deep cavity that is into or at least close to the nerve, or an old filling (usually amalgam/silver) that has led to cracks in the tooth.
Best way to prevent it is to see you Dental team regularly so they can monitor them before they break or before a cavity gets deep. At home you can prevent the problem by flossing before brushing 1-2x a day, using an electric toothbrush twice a day using fluoride based toothpaste and then finish with a good anti bacterial, alcohol free mouth rinse.

Bad breath can come from an infection in the mouth. If it’s not a decayed tooth/teeth, then most bad breath, 80%-90%, comes from the tongue, and the rest from sinus drainage or reflux from the stomach. A few things that can help:

-use a tongue scraper (not just your tooth brush), brush the roof of your mouth, and your cheeks, too.
-stay hydrated, as dry mouth causes bad breath
-check your medications, hundreds of medications have a side effect listed as Xerostomia or dry mouth
-use an oral care system like Biotene that is designed to help with dry mouth
-ask your dental team about Xylimelts as that is another product we have had good success using for our patients.
