The Surprising Link Between Allergies and Oral Health

Spring brings sunshine, blooming flowers—and, for many, a flurry of sneezing, watery eyes, and sinus congestion. While allergy season is usually associated with nasal discomfort, it may surprise you to learn that it can also impact your oral health. 

At Flatiron Family Dental, we believe in a comprehensive approach to dental care, including understanding how seasonal allergies can affect teeth and gums.

1. Dry Mouth from Antihistamines

Antihistamines are a go-to remedy for allergy symptoms, but they often cause dry mouth as a side effect. Saliva plays a vital role in washing away food particles and bacteria. Without enough of it, your risk of cavities, gum disease, and bad breath increases. To combat dry mouth:

  • Stay hydrated
  • Chew sugar-free gum
  • Use a humidifier at night
  • Ask your dentist about mouthwashes that promote saliva production

2. Sinus Pressure and Tooth Pain

Allergy-related sinus inflammation can cause pressure in the upper jaw, which sits right below your sinuses. This pressure can mimic a toothache—especially in your upper molars. If you notice dental pain that seems to come and go with your sinus symptoms, it’s likely allergy-related. Still, having your dentist rule out any underlying dental issues is always best.

3. Mouth Breathing and Gum Health

When your nose is congested, you may breathe through your mouth more often. This can dry out your gums and cause inflammation, increasing your chances of gum disease. Rinsing with water and using a saline nasal spray to relieve congestion can help keep your oral tissues healthy.

4. Postnasal Drip and Bad Breath

Allergy-related postnasal drip can cause a sore throat and contribute to bad breath. Brushing your tongue, staying hydrated, and rinsing with a gentle antibacterial mouthwash can help control unpleasant odors and maintain a fresh mouth.

5. Heightened Sensitivity

During allergy season, your teeth may feel more sensitive due to sinus pressure or increased inflammation. If this persists beyond allergy season or worsens, schedule a visit with your dentist to rule out other causes.
