Spring might be winding down, but here in San Diego, June often brings a surge in seasonal allergies. If you’re among the many people sneezing, sniffling, and battling congestion this time of year, you’re not alone. Pollen, grass, and dust particles are all in the air—and for allergy sufferers, that can mean itchy eyes, sinus pressure, and more trips to the medicine cabinet.

But there’s one area many people overlook during allergy season: oral health.

At Clairemont Dentistry, we believe that caring for your smile goes beyond just brushing and flossing. Understanding how seasonal allergies impact your teeth, gums, and mouth can make all the difference in staying comfortable—and preventing issues before they start.

Here’s what to know about protecting your smile this allergy season, plus helpful advice from Dr. Yaron Miller and the Clairemont Dentistry team.

Can Allergies Really Affect Your Oral Health?

Absolutely. Although most people associate allergies with respiratory symptoms, the effects can ripple through your entire body—including your mouth.

Here are the most common ways allergies can influence your oral health:

1. Dry Mouth (Xerostomia)

When nasal congestion makes it hard to breathe through your nose, you may find yourself breathing through your mouth instead—especially while sleeping. This leads to dry mouth, a condition where saliva production is reduced. Without adequate saliva, your mouth becomes a more welcoming environment for harmful bacteria. Over time, this increases your risk for:

• Cavities
• Gum disease
• Mouth sores
• Bad breath

Some allergy medications, particularly antihistamines, can also contribute to dryness, further compounding the problem.

2. Post-Nasal Drip and Bad Breath

Post-nasal drip is a common allergy symptom that sends mucus trickling down your throat. This mucus can coat your tongue and soft tissues, leading to unpleasant breath. Even if you’re brushing regularly, this hidden source of odor can linger—especially when dry mouth is also at play.

3. Tooth Pain from Sinus Pressure

Did you know your upper back teeth share a close relationship with your sinus cavities? When your sinuses become inflamed or filled with fluid, the pressure can press down on the roots of your molars. This can cause a dull ache or tenderness that mimics a toothache. If you've ever felt tooth pain that seemed to move or worsen with your sinus congestion, allergies might be the culprit.

Why June in San Diego Can Be a Trigger

Many San Diegans associate allergies with springtime blooms, but June brings its own challenges. Thanks to our coastal climate and native plant life, allergens like grass pollen and mold spores can remain elevated throughout late spring and early summer. Add in June Gloom’s damp mornings and you’ve got a perfect recipe for sinus irritation and oral discomfort.

Simple Ways to Protect Your Smile This Season

The good news? A few smart habits can go a long way in minimizing allergy-related oral health problems. If you're experiencing allergy symptoms, try incorporating these dentist-approved tips into your routine:

Stay Well Hydrated

Water is your best defense against dry mouth. Try to sip throughout the day—even if you're not feeling thirsty. Keeping your mouth moist helps rinse away allergens and bacteria while encouraging saliva production. It also helps soothe irritated throats caused by post-nasal drip.

Rinse After Being Outdoors

After spending time outside, especially during peak pollen hours (usually morning and early evening), rinse your mouth with water or an alcohol-free mouthwash. This can help flush away allergens that have settled on your teeth, gums, and tongue.

Try a Humidifier at Night

Using a humidifier in your bedroom adds moisture to the air, which may ease congestion and reduce mouth breathing while you sleep. This simple trick can help preserve your natural saliva levels and make mornings feel a little fresher.

Maintain a Strong Oral Care Routine

Allergy fatigue can make it tempting to skip brushing or flossing—but that’s when your smile needs extra support. Brush gently twice a day with fluoride toothpaste, floss once daily, and consider a tongue scraper to help remove mucus buildup. You may also benefit from a professional cleaning if symptoms persist.

Consider Allergy Management Alternatives

If your current medications are causing significant dry mouth, ask your healthcare provider or allergist if alternative options are available. Some patients find relief with non-drying antihistamines or nasal steroid sprays that preserve moisture.

When Tooth Pain Signals Something More Serious

While sinus pressure can certainly cause tooth discomfort, it’s important not to dismiss ongoing or severe pain. Here’s how to tell the difference:

• Sinus-related pain tends to affect multiple upper teeth, often on both sides. It may feel worse when you bend over or lie down.
• Tooth decay or infection usually affects a single tooth and may be sharp, constant, or triggered by hot/cold foods.

If you're unsure, let us help. Our team can determine whether you're dealing with seasonal discomfort or a more serious issue that needs treatment. Our emergency dental care services are available for those moments when you're in pain and need quick answers.

A Patient Story: Jessica Finds Relief

Jessica, a busy mom of three living near Clairemont Mesa, had been waking up with a dry mouth and sensitive teeth every June for years. “I used to think it was just stress or not brushing well enough,” she said. “But then the tooth pain started—and I was worried I had a cavity.”

During her visit to Clairemont Dentistry, Dr. Miller reviewed her symptoms and asked about her allergies. Together, they pinpointed the root cause: sinus pressure and dry mouth, made worse by an over-the-counter antihistamine.

Dr. Miller recommended switching to a nasal spray, increasing her water intake, and using a hydrating mouth rinse at night. Within two weeks, Jessica’s symptoms had improved dramatically.

“I couldn’t believe something as simple as breathing through my mouth could cause so much trouble. Thanks to Dr. Miller, I now know how to manage my allergies and protect my smile.”
