Why Do My Top Teeth Hurt When My Allergies Are Bad?

In Baltimore's peak pollen season, upper tooth pain is often caused by sinus congestion rather than a cavity. Because the roots of your upper teeth sit directly beneath the maxillary sinuses, inflammation from seasonal allergies can put pressure on dental nerves, mimicking a toothache.

The Hidden Connection Between Sinuses and Tooth Pain

Your upper back teeth are located very close to your maxillary sinuses—air-filled spaces that can become inflamed during allergy season. When pollen levels rise in the Baltimore and Woodlawn area, your sinuses can swell and create pressure that radiates downward into your teeth.

This can feel like:

• A dull, aching pain in multiple upper teeth
• Pressure that worsens when bending over
• Discomfort that comes and goes with congestion

Because of this overlap, many patients assume they have a cavity when the real issue is sinus-related.

The “Desbordes Diagnostic Edge”

At the office of Dr. Byron Desbordes, DDS, we take a precise and technology-driven approach to diagnosing tooth pain.

Using advanced tools from our dental technology page, including:

• Digital X-rays
• Intraoral cameras

Dr. Desbordes can quickly determine whether your pain is caused by:

• A true dental issue like decay or infection
• Or sinus-related referred pain

This ensures you get the correct diagnosis without unnecessary treatment.

At-Home Relief vs. When to See a Dentist

Not all tooth pain is the same. Here’s how to tell the difference:

It May Be Sinus-Related If:

• Pain affects multiple upper teeth
• Discomfort is on both sides
• Pain changes with congestion or improves with allergy medication

You Should See a Dentist If:

• Pain is localized to one tooth
• You feel sensitivity to hot or cold
• Pain persists after congestion improves
• There is swelling or pain when chewing

If you’re unsure, a professional exam is the best way to rule out infection.

The Bigger Picture: Oral Health & Whole-Body Wellness

At our practice, oral health is closely connected to overall health. Inflammation—whether from sinus issues or dental conditions—can affect the entire body.

This is especially important for patients with:

• Diabetes
• Heart disease
• Chronic inflammatory conditions

Dr. Desbordes takes a comprehensive approach to care, ensuring your diagnosis supports both your dental and overall health.
