Many people experiencing the discomfort of a sinus infection are surprised to find themselves also dealing with upper tooth pain. It’s a confusing and often frustrating experience, leaving many wondering about the connection between these seemingly separate issues. You’re not alone if you’ve felt this peculiar ache!
We’ll look at how sinus infections can indeed affect your teeth, providing clarity on why this happens. We’ll also explore the intricate anatomy that links your sinuses and upper jaw, help you differentiate between sinus-related and true dental pain, and outline the steps you should take to find relief. If you’re in the Los Angeles area and experiencing these symptoms, knowing when to seek an ENT for a sinus infection in LA is important.
Understanding Sinus Anatomy
To understand why a sinus infection might lead to tooth pain from sinus issues, it’s helpful to have a basic grasp of your sinus anatomy. You have several pairs of sinuses, air-filled cavities in your skull. The maxillary sinuses are the ones most relevant to upper tooth pain, as they are located directly above your upper back teeth (molars and premolars).
Imagine these sinuses as small rooms situated just above the roots of your upper teeth. When the lining of these sinuses becomes inflamed or infected—the hallmark of a sinus infection—the resulting pressure can have a direct impact on the nerves and tissues in the vicinity. This proximity is the key to understanding the often-surprising link between your sinuses and your teeth.
When a sinus infection takes hold, the inflamed sinus lining begins to swell and produce excess mucus. This buildup increases pressure within the sinus cavity. Because the roots of your upper back teeth are so close to the floor of the maxillary sinuses, this pressure can easily push down onto these roots and the surrounding nerve endings. The result? Pain that feels like it’s originating from your teeth.
How a Sinus Infection Can Cause Tooth Pain
Let’s break down the mechanisms behind this referred pain.
Sinus Pressure and Inflammation
As mentioned, the inflammation of the sinus lining during a sinus infection can lead to a buildup of pressure. This increased pressure within the maxillary sinus can directly compress the nerve endings located near the roots of your upper molars and premolars. This compression can manifest as a dull ache, pressure, or even sensitivity in your upper teeth.
Shared Nerve Pathways
Interestingly, some of the nerves that serve your sinuses also have connections to the nerves in your upper jaw. This overlap in nerve pathways can sometimes lead to a phenomenon called referred pain. Essentially, your brain might misinterpret the pain signals originating from the inflamed sinuses as coming from your teeth. This explains why you might experience sinusitis and dental pain simultaneously, even if your teeth are perfectly healthy.

Signs Your Tooth Pain Is Sinus-Related
How can you tell if your tooth pain is a result of a sinus infection rather than a dental problem?
- Pain in multiple upper teeth, not just one: Sinus pressure tends to affect a broader area, often causing discomfort across several upper teeth.
- Accompanied by classic sinus symptoms: If your tooth pain is linked to a sinus infection, you’ll likely also experience other common sinus infection symptoms such as nasal congestion, facial pressure (especially around the cheeks and forehead), headache, post-nasal drip, and potentially fatigue or a mild fever.
- Pain worsens when bending forward or lying down: Changes in head position can affect the pressure within your sinuses, often making sinus-related tooth pain more noticeable when you bend over or lie flat.
- Tooth feels sensitive but not sharply painful or triggered by hot/cold food: Sinus-related tooth pain is often described as a dull pressure or ache, rather than the sharp, acute pain often associated with dental issues like cavities or sensitivity.
When It Might Not Be Sinus-Related
It’s also important to recognize when your tooth pain is more likely a dental issue. Consider these indicators:
- Pain in a single tooth that worsens with chewing or temperature changes: Localized pain that’s aggravated by eating or hot/cold stimuli is more indicative of a dental problem.
- Visible swelling or abscess on gums: These are clear signs of a potential dental infection.
- No accompanying sinus symptoms: If you have tooth pain without any nasal congestion, facial pressure, or other signs of a sinus infection, the cause is likely dental.
- Pain persists after the sinus infection resolves: Tooth pain that continues even after your sinus symptoms have cleared up warrants a dental check-up.
Diagnosing the Cause of Your Tooth Pain
Getting an accurate diagnosis is the first step towards relief. Your doctor or dentist may employ several methods to determine the cause of your tooth pain:
- ENT exam and/or sinus imaging: An ENT in Los Angeles can perform a thorough examination, potentially including nasal endoscopy or imaging like a CT scan, to detect any signs of infection or blockage in your sinuses.
- Dental exam and X-rays: Your dentist will examine your teeth and gums and may take X-rays to rule out issues like decay, abscesses, or root damage.
In some cases, a multidisciplinary approach involving both an ENT Specialist near me and a dentist may be necessary for a definitive diagnosis, especially when symptoms are overlapping or unclear.

Treatment Options
The treatment for your tooth pain will depend entirely on its underlying cause.
For Sinus-Related Tooth Pain
If your tooth pain is indeed due to a sinus infection, treatment will focus on resolving the infection and reducing sinus inflammation. This may include:
- Antibiotics (if a bacterial infection is confirmed)
- Nasal sprays or decongestants to help clear sinus passages
- Saline rinses and steam inhalation to soothe inflammation and loosen mucus
- Over-the-counter pain relievers to manage pain and inflammation
- In chronic cases, a Los Angeles ENT doctor might recommend more advanced treatments like sinus surgery or balloon sinuplasty.
If It’s a Dental Issue
If your tooth pain stems from a dental problem, your dentist will recommend appropriate treatment, which could involve:
- A filling for a cavity
- A root canal for an infected tooth pulp
- An extraction for a severely damaged tooth
- Antibiotics are used if there’s a dental infection requiring medication.
When to See a Doctor or Dentist
It’s important to know when to seek professional help. Schedule an appointment with your doctor or dentist if:
- Your pain lasts for more than 10 days or seems to be getting worse.
- You experience symptoms suggestive of a severe sinus infection, such as a high fever or thick green/yellow nasal discharge.
- Your tooth pain is sharp, persistent, or clearly localized to a single tooth.
- You find that tooth pain recurs with every cold or allergy season.
Conclusion
Yes, sinus infections can absolutely cause tooth pain, particularly in the upper jaw. The close anatomical relationship between the maxillary sinuses and the roots of your upper teeth, along with shared nerve pathways, makes this a common occurrence. Understanding the difference between sinus-related and true dental pain is key to seeking the right kind of treatment and finding relief.
If you’re experiencing upper tooth pain alongside sinus infection symptoms and are unsure of the cause, don’t hesitate to seek professional guidance. Schedule an appointment with Southern California Sinus Institute for an accurate diagnosis and a tailored treatment plan. Getting to the root of the problem is the first step towards a pain-free smile and clear sinuses!
