Sinus Infection Tooth Pain: Causes, Symptoms, and Relief Tips

Asad A | November 13, 2024

When a sinus infection strikes, the pressure and discomfort can radiate beyond the sinuses, often impacting other areas of the face—sometimes even leading to unexpected tooth pain. For many, this can cause confusion, as the ache in the upper teeth may seem like a dental issue.

But in reality, sinus infections and dental discomfort are closely linked due to the proximity of the sinus cavities to the upper jaw. Understanding the connection between sinus infections and tooth pain can help you find the right relief and know what steps to take.

Understanding Sinus Infections

Because your sinuses are located close to your mouth, the pressure from an infection can create discomfort in your upper teeth. This kind of pain may also stem from a typical toothache.

A sinus infection, or sinusitis, can trigger toothache-like pain. Sinusitis develops when the tissues lining the sinuses become inflamed and swollen.

Tooth pain is frequently associated with sinusitis. The pressure and drainage caused by a sinus infection can lead to discomfort in the teeth, typically affecting the upper back teeth that are closest to the sinuses.

Sinus Infection vs. Normal Toothache

The symptoms of a sinus-related toothache can closely resemble those of a typical toothache. However, sinus tooth pain usually affects the upper molars and tends to impact multiple teeth rather than just one.

If you’re experiencing pain in these teeth along with some of the symptoms described below, it’s likely your toothache is related to a sinus infection. You might also notice feeling a bit low on energy or even running a fever.

In contrast, tooth pain from a dental issue typically stays more localized, often focusing on a single tooth with more intense discomfort.

Symptoms of Sinus Infection Tooth Pain

Pain in Multiple Teeth 

Sinus infections often cause pain in several upper teeth, especially the molars, due to sinus cavity pressure on the tooth roots. Unlike a typical toothache, this discomfort isn’t limited to one tooth but spreads across several.

Pain When Moving the Head or Chewing 

Pain may intensify when bending over, moving your head, or chewing, as these actions shift sinus pressure. This increased pressure can make daily activities uncomfortable, distinguishing sinus pain from regular dental pain.

Nasal Congestion 

Nasal congestion is a common symptom of sinus infections, causing a blocked or stuffy feeling in the nose. This congestion puts extra pressure on surrounding areas, leading to discomfort that radiates to the teeth and face.

Mucus Buildup

Excess mucus from sinus congestion can cause discomfort as it blocks nasal passages and puts pressure on nearby teeth. This buildup also leads to a feeling of fullness or pressure in the face, intensifying tooth and facial pain.

Causes of Sinus Infection Tooth Pain

Sinus Pressure 

When the sinuses are inflamed, they fill with fluid and cause a buildup of pressure around the nose and cheeks. This pressure can press against the roots of the upper teeth, leading to tooth pain that feels similar to a dental issue. 

Inflamed Sinus Linings 

The tissues lining the sinuses can become swollen and inflamed during an infection, putting pressure on adjacent areas, including the upper jaw and teeth. This inflammation is a primary cause of sinus-related tooth pain, especially in the upper molars.

Infection Spread 

In severe cases, a sinus infection can spread to other areas close to the sinuses, causing additional pain. This spread can affect the nerves around the upper jaw, leading to heightened tooth pain that may mimic a dental problem.

Increased Blood Flow to Infected Areas 

A sinus infection triggers the body to increase blood flow to affected areas as part of the immune response. This increased circulation can cause swelling in the sinuses and surrounding tissues, resulting in a throbbing or dull ache in the upper teeth due to pressure.

Useful Relief Tips for Sinus Infection Tooth Pain

Stay Hydrated 

Keeping yourself well-hydrated is essential for easing sinus congestion. Aim to drink plenty of water and other fluids, as this helps to thin mucus and reduce sinus pressure and blockages. Warm drinks like tea or soup can be especially comforting.

Steam Inhalation 

Inhaling warm, moist air can help clear nasal passages and relieve sinus pressure. Pour boiling water into a large bowl, place your face over it, cover your head with a towel, and breathe deeply for a few minutes. A hot steam shower, taken twice daily, can also provide relief.

Sinus Rinse 

Using a saline solution to rinse your sinuses can help keep them moist and remove allergens and mucus buildup. You can use a premixed saline solution and a nasal sprayer, Neti pot, or irrigation system with distilled or boiled water. Avoid using tap water for this process.

Over-the-Counter Pain Relievers 

To manage mild tooth pain, you can use an OTC pain reliever like ibuprofen (Advil, Motrin), acetaminophen (Tylenol), or aspirin. 

Hot and Cold Therapy 

Try alternating a heating pad and a cold compress on the painful area for 15 minutes each. Repeat this a few times during the day to reduce pain and swelling.

Conclusion

Sinus infection-related tooth pain can be a confusing and uncomfortable experience, as the pressure from inflamed sinuses often mimics a dental issue. Understanding the connection between sinus infections and tooth pain is essential for identifying the source of discomfort. 

By addressing both the sinus infection and the tooth pain, you can find effective relief and prevent further complications.
