When allergy season comes around, it can be a nightmare for most people. Nobody likes getting hay fever. And when you’re besieged with a slew of allergy symptoms—sore throat, itchy eyes, stuffy nose—it can be pretty unbearable. If that wasn’t enough, you might have one more reason to despise spring allergies: sore teeth. One question remains, however: how can allergies cause sore teeth?
Well, in a way, yes. But it’s probably not the way you expect it to be. At first, the signs might feel like a typical tooth decay-induced dental issue. Before you’re tempted to over-brush your teeth or catch up on the floss, however, it’s important to note that sore teeth from allergies might not be a tooth problem. As a matter of fact, it might not even be a dental health problem. Despite what you feel, however, none of the pain actually comes from your teeth, but somewhere closer.
So how can allergies cause sore teeth? Let’s take a closer look.
Can allergies cause sore teeth? Yes, thanks to sinus congestion
When you get painful teeth from spring allergies, it’s not the same thing as getting short-term gingivitis during puberty. Instead, it’s more of a collateral pain coming from another part of your body. And when you have allergy symptoms, what’s the one part of the face that’s affected most of the time? That’s right—it’s your sinus cavity.
When you suffer sinus congestion or sinus inflammation, you’ve probably felt something akin to intense pressure in the center of your face. Sometimes it even creeps across your eyebrows. To understand why you feel a sense of tightness along the area when you have an allergy, it might help to know how the sinus cavity works.
In a nutshell, the sinus cavity is where nasal mucus is made. That’s right, the stuff that lines your nasal passages. If you look at the sinus, you’ll find that it’s also covered with tissues where the mucus is secreted. These tissues are called the mucosa.
When you get hay fever or spring allergies, these tissues get inflamed and secrete more mucus than they’re supposed to. As it does, your sinus cavity begins to constrict, causing pressure to build up. But while it’s common to feel the pain from this pressure on your face, sometimes you can feel it in your teeth, too.
How to find relief from sinus-related tooth pain
Before you reach for the antihistamine, take note that not all cases of tooth pain are allergy-related. To tell the difference, determine where the pain is coming from. If you can feel pain mostly near your upper molars, that’s a surefire sign that it’s one of those allergy symptoms. If that’s the case, you can take an over-the-counter antihistamine to see if your toothache is allergy-related. You’re more likely to find relief right after.
If your toothache affects more than just your top molars, however, you might want to head to the nearest dentist to get those teeth checked. You want to eliminate the possibility of tooth decay as soon as possible. Otherwise, left untreated, it might lead to something worse than sore teeth. So while allergies can cause sore teeth, when in doubt, don’t hesitate to ask your dentists.
