The Unexpected Link between Seasonal Allergies & Dental Health

Seasonal allergies are the worst. You don’t feel great for days on end, and, depending on the severity of the allergies, they may even cause you to miss out on the things you enjoy – like spending time with friends or going on that big trip. But did you know that allergies can also take a toll on your teeth and gums? Many people don’t realize the connection between seasonal allergies and dental health. Your Raleigh dentist is here with the information you need to know. 

What Seasonal Allergies Are

Most people get seasonal allergies twice a year, in the spring and fall, when the air is filled with substances from pollination that cause irritation in the nasal cavity. As opposed to a cold or flu, you won’t have a fever with seasonal allergies – but many of the other symptoms are the same. They include:

  • Runny nose
  • Itchy throat
  • Watery eyes
  • Cough
  • Sneezing

Seasonal Allergies and Your Oral Health

While your main focus is probably on your coughing, sneezing, and watery eyes, you should also consider the side effects that these symptoms can have on your oral cavity. Congestion leads to mouth breathing, which can cause dry mouth – especially at night while you sleep, when you go hours without eating or drinking anything. Without the proper amount of saliva to wash away food particles and bacteria, dry mouth can lead to bad breath, tooth decay, and even gingivitis, the earliest stage of gum disease.  

Post-nasal drip caused by allergies can also increase the amount of bacteria in your mouth, leading to bad breath and further increasing your risk of getting cavities or gum disease.

How to Protect Your Teeth and Gums From Allergy Season

If you are constantly reaching for the tissues in the spring and fall months due to your allergies, you should also be reaching for your toothbrush and floss. Cleaning your teeth as recommended will help protect you from the increased risk of tooth decay and gum disease that allergies cause. You may also want to consider upping your water intake, which will keep you hydrated and help prevent dry mouth. Chewing sugar free gum is another great way to help your mouth wash away bacteria to reduce your risk of developing oral health issues.

Now that you know about the risk allergy season brings to your smile, consider that it’s also a great time to visit the dentist! Getting a professional checkup and cleaning will help you head into the fall with a clean and healthy smile – so you’re extra protected from any problems brought on by pollen.

I've been coming to this practice for years now since moving to the Raleigh area. The office is always clean and organized and the staff have always been friendly and communicative. Also, the TV's mounted to the ceiling are a nice touch! I've been seeing Dr. Laster for several years before our insurance changed causing me to change to Dr. Rensch. Both are so easy to talk to and always made me feel at ease.

From beginning to end 5/5! I thought I was experiencing a dental 911. I submitted an inquiry at 11:30pm and by 8am the next morning, Deidra (front office staff) was already leaving me a message. She was so sweet and patient at 8am lol. After our initial conversation, I informed all follow up dentists “I found my dentist office” but thank you so much! Today I was welcomed with the same energy from Diedre to Britany then finally Dr.Wrench. The music playing throughout the office was fantastic; ie music selection and volume. The TV’s on the ceiling and wall made my procedure so painless and enjoyable! I watched an entire Christmas movie lol! Dr. Wrench (apologies for spelling) made my teeth absolutely perfect! I left telling my friends and family I have a million dollar smile! 😊 I can tell he wanted them perfect and he did! Thank you all so much for being amazing! Sincerely, Your next patient.

Dr. Laster and Dr. Rensch go above and beyond for their patients. I have seen both for various treatments and I always feel comfortable and heard. They take time to listen and to talk with you. They explain your options and work with you to develop the best plan for your care. They are always upbeat and positive and you can tell they truly love what they do. The front desk staff is exceptional as well. Deidre is so caring and very sweet. She’s efficient, understanding and conscientious of your time. I highly recommend.

Connections Dentistry was great! The staff is so friendly and truly cares about their patients. My appointment was quick, and honestly the best dental experience I’ve had. They are great about offering helpful solutions without making you feel like you are being reprimanded… which was the reason I was putting off the dentist. 100% recommend!
