Impact of seasonal allergies on your oral health


How do Seasonal Allergies Affect Your Oral Health?

Spring arrives, but unfortunately, all seasonal allergies lead to congestion, watery eyes, sneezing, and many other things. It makes it very difficult to enjoy spring. But do you know it also affects your oral health?

Allergies act like a catalyst for several oral issues, such as the dry mouth. When you have a congested and stuffy nose, you start breathing through your nose, which causes a dry mouth. Other than that, antihistamines also cause dry mouth. A dry mouth is uncomfortable and creates an environment for the cavity-causing bacteria to increase. This is so because the saliva in our mouth plays a vital role in cleaning the bits of food and the plaque attached to teeth. When saliva production is reduced , the teeth are susceptible to cavities, gingivitis, and bad breath.


If you get allergies, you might notice that your oral hygiene decreases during allergy seasons. It is not coincidental because seasonal allergies affect your respiratory system and hurt your mouth and oral tissues. Have a look at how some seasonal allergies can hurt your dental health:


Bad breath: You might think bad breath is a tiny problem while struggling with congestion and postnasal drip. But Bad breath is quite off-putting to other people and is embarrassing while doing professional and personal interactions. Bad breath also impacts the taste of your food and drinks, distracting you from enjoying your meals. 

If you feel that your bad breath is not improving even after brushing and flossing correctly, those seasonal allergies can be the reason. Allergies lead to postnasal drip from a lot of mucus draining from the sinus cavity to your throat. Bacteria present in that mucus causes throat infection. This bacteria, in turn, gives an unpleasant smell that comes out of your mouth while you breathe. You are not getting rid of bad breath because of its origin in the throat. No matter how much you brush or floss, you will not get rid of it.

What will help? You might have to take an antibiotic to clear the infection. For a temporary remedy, you can try some mint and gum. Gargling with salt water will soothe your sore throat, and will help in quickly eliminating the smell. Salt has antibacterial properties that help in reducing the bacteria that cause the issues.


Toothaches: When your teeth hurt, you might think that you have a cavity or any tooth infection or have injured your teeth. But when you have seasonal allergies, you can develop a toothache, another allergy symptom. Like different allergy symptoms, a toothache is also caused because of mucus. When your allergies are acting up, slime builds in your sinuses, leading to congestion. The maxillary sinuses on either side of the nose sit on the upper jaw. 

When sinuses are congested, they start putting some pressure on teeth and nerves in your mouth, resulting in tooth sensitivity and toothaches. You might notice some pain while eating or drinking something hot or cold or moving your head, or you will also get the pain consistently.

What will help? When your toothache is because of allergies, you can take some over-the-counter anti-allergy medication that helps in getting relief from sinus congestion. 


Swelling of gums and tonsils: People suffering from allergies get a post-nasal drip, resulting in consequences like gum swelling, tonsil inflammation, etc. When there is inflammation in your gums, it can cause pain when you brush and floss. Never forget that ineffective teeth cleaning activities often shelter the microbes over gums and teeth. It makes you highly vulnerable to severe consequences like sore gums, periodontal diseases, etc.


Sore throat: Post–nasal drip, caused by allergies, is one of the common causes of sore throat. As previously discussed, it can cause bad breath.

It is imperative to keep your oral health in check when you have seasonal allergies. Try to remain hydrated to combat the effects of a dry mouth and help the body wash away all excess mucus. Maintain a regular brushing and flossing routine, which is vital for preventing tooth cavities. Treat the allergies, avoid all those triggers, and discuss with your dentist long-term solutions. If you have been experiencing unusual dental pain or issues, address those issues with your dentist. 

Allergies in the spring season are enough to cause hassles without adding any oral problems to your plate. If you are a sufferer of seasonal allergies, you can discuss with your dentist various things you can do to treat or prevent the allergy symptoms that affect your dental health.
