If you don't see your dentist on a regular basis — at least twice a year — you're at an increased risk for tooth infections. Unfortunately, tooth infections aren't something that should be taken lightly. In fact, if not treated, a tooth infection can spread to the rest of your body. Once in your body, a tooth infection can cause decreased urine output, increased heart rate, and vomiting, which is why you need to resolve the problem as soon as possible. Take a look at the list provided below. If you're experiencing any of the problems listed here, you need to see your dentist right away. You could have a tooth infection that requires immediate attention. 

Swelling

If you have a tooth infection that has progressed to an advanced stage, you could start noticing increased swelling in your face and jaw. In most cases, the swelling will begin in the cheek that's on the affected side of your mouth. However, as the infection progresses, the swelling could spread to the rest of your face and into your jaw. In severe cases, the swelling may make it difficult for you to swallow or open and close your mouth. 

Bad Breath

If you're experiencing a case of bad breath, and you're brushing and flossing the way you should, it's time to visit your dentist. Bad breath can be a sign of a tooth infection, especially when all other causes have been ruled out. The bad breath may be from deposits of pus that's accumulated below the gum line as a result of the infection. Visit your dentist at the first sign of bad breath that won't go away with brushing and flossing. 

Increased Pain

If you've developed a toothache, you need to take it seriously, especially if the pain isn't resolved with over-the-counter pain medication. Toothaches often result in infections, especially when they're caused by cavities or decay. Unfortunately, toothache pain can become quite severe. If you have a throbbing toothache, or if the pain has radiated into your ear, you need to visit your dentist right away. 

Inflamed Lymph Nodes

If you have an unresolved infection in your tooth, you may start noticing changes to your lymph nodes, especially those that are located along the edge of your jawbone. During a tooth infection, the lymph nodes along your jawline can become inflamed. If that happens, you'll be able to feel small lumps — about the size of peas — along the edge of your jaw. If you have inflamed lymph nodes along your jaw, see your dentist immediately.
