Toothaches are fairly common for many people. With so many culprits behind them, it may be nearly impossible to never experience them. That said, if you have one, then you might hope that it will go away over time. However, oral health issues can’t heal on their own. In fact, they can even have an impact on your overall health if you aren’t careful. Here’s what you should know that might have you looking up an emergency dentist near you.

What Causes Toothaches?

As mentioned above, there are several reasons that can cause toothaches. Sinus pressure is one that can resolve itself, but dental-related problems aren’t so lucky. Teeth grinding or clenching can occur subconsciously during the night, so you may not even realize you’re doing it until you feel that discomfort.

That said, a worrying one is an infection. Bacteria that are attacking the inner pulp can cause harm not only to the structure, but they can even spread to your nearby teeth, gums, or the rest of your body.

So, Can a Toothache Become Fatal?

The germs that cause a tooth infection can travel through your bloodstream and increase your risk of other conditions, such as sepsis, meningitis, or Ludwig’s Angina. However, it becoming fatal is rare today. Advanced diagnostic technology can pinpoint the issue to help your dentist give you an effective solution.

People in the past weren’t as fortunate. This problem was the fifth to sixth leading cause of death in the 1600s, and in 10% to 40% of cases were still lethal up until 1908.

How Are Toothaches Treated?

Thankfully, you can breathe a sigh of relief knowing your toothache won’t be trouble if you get it checked out. By heading to your dentist, they can do an exam to find the culprit. If teeth grinding or clenching is the issue, then a nightguard can protect your smile while you sleep. Tooth infections are often handled by a root canal. The affected pulp will be removed, and a crown will be placed to restore the structure’s function and appearance.

You can breathe a sigh of relief that toothaches being fatal is rare nowadays. Though that doesn’t mean you should postpone a visit to your provider about one. Looping them in sooner rather than later can give you a worry-free grin that may also protect your overall health.
