One of the more confusing experiences for our patients is the sudden onset of upper-tooth or jaw pain that seems to have no dental cause. A visit to the dentist reveals healthy teeth, yet the ache persists. In many cases, this discomfort is actually caused by sinus pressure, which can mimic dental pain and create a deep, aching sensation in the upper teeth and jaw.
This type of sinus pressure often worsens when bending forward, flying, or waking up after a cold. The sinuses sit directly above the upper teeth, and when inflamed, they press on shared nerves, radiating pain into the mouth and jaw. This guide explains how sinus pressure leads to tooth pain, how to relieve it using targeted pressure points, and when professional care is the right next step.
Key Takeaways
- The maxillary sinuses sit directly above the upper back teeth, and sinus pressure can easily be mistaken for a toothache due to shared nerve pathways.
- Classic sinus pressure-related dental pain affects several upper molars at once, worsens with bending forward, and often follows a cold or allergy flare.
- Acupressure points such as LI20 (Yingxiang), Bitong, GB20, ST3, and ST7 can help relieve sinus pressure and reduce referred tooth and jaw pain.
- Warm compresses, steam, hydration, and proper sleep posture can help ease sinus pressure and improve overall comfort.
- Persistent or one-sided tooth pain, fever, swelling, or visible pus may not be due to sinus pressure and should be evaluated by a dental or ENT professional.
Why Sinus Pressure Causes Tooth and Jaw Pain
The maxillary sinuses are a pair of air-filled cavities in the cheekbones, and the roots of your upper molars sit just below, sometimes only a paper-thin layer of bone separates them. When the sinuses become inflamed, the lining swells, mucus accumulates, and internal pressure rises. That pressure transmits directly to the roots of the upper teeth, and the trigeminal nerve branches that serve both the sinuses and the teeth cannot always distinguish between the two.
The result is classic referred pain: your brain receives a signal it interprets as “tooth pain” when the actual inflammation is a few millimeters higher, in the sinus cavity. The Cleveland Clinic’s overview of sinusitis describes this overlap and notes that dental-like pain is a common presenting complaint for sinus infections. The American Academy of Family Physicians’ clinical review of acute sinusitis adds that maxillary tooth pain, especially when bilateral or affecting multiple teeth, should raise suspicion for a sinus origin.
Sinus Pain vs. a Real Dental Problem
A few clinical clues help distinguish the two. Sinus-related tooth pain tends to involve several upper back teeth at once, worsens with bending forward or lying flat, and is often accompanied by facial pressure, nasal congestion, or a recent upper respiratory infection. True dental pain is typically localized to a single tooth, sharper in quality, and may be triggered by specific stimuli such as cold, heat, or biting down. When the pattern is ambiguous, a dental exam clears the easy answer first, and an ENT or primary care visit addresses the sinus side.
The Jaw Connection: When the TMJ Joins In
Facial pain often does not respect neat anatomical boundaries. When sinus congestion lingers, patients frequently start clenching their jaw, sleeping poorly, or breathing through their mouth — all of which load the temporomandibular joint (TMJ). A stressed TMJ, in turn, can refer pain into the cheek, ear, and upper teeth, compounding the original sinus problem. In our Setauket practice we see this combination regularly, and our TMJ disorders treatment page describes how we approach the muscular and joint contributions alongside the sinus picture.
The Acupressure Points That Matter for Sinus-Related Dental Pain
Acupressure for sinus-related tooth and jaw pain works by reducing facial congestion, calming the surrounding muscles, and supporting mucosal drainage. A systematic review of acupuncture for chronic rhinosinusitis reported that acupuncture-based interventions may offer symptom improvement, and a small controlled study of Yingxiang (LI20) nasal massage found benefit for nasal airflow and symptom scores. Below are the points we most often teach patients who present with sinus-driven dental or jaw pain.
LI20 (Yingxiang) — “Welcome Fragrance”
LI20 sits in the groove where the outer edge of each nostril meets the cheek. It is the workhorse point for relieving nasal congestion and sinus pressure, especially in the maxillary region. To use it, place the pads of your index fingers on both sides simultaneously and apply firm pressure with small circular motions for about one minute. This technique can quickly reduce sinus pressure, and you may feel a sense of “opening” through the nose within thirty to sixty seconds.
Bitong — The Extra Point at the Nasal Bridge
Bitong is an “extra point” that lives just above LI20, at the top of the smile line where the nasal bone meets the cartilage. Gentle, steady pressure here—again on both sides simultaneously—helps drain the upper portion of the maxillary sinus and reduces sinus pressure transmitting down to the roots of the upper teeth. Holding this point for thirty to sixty seconds can noticeably ease sinus pressure and facial discomfort.
GB20 (Fengchi) — At the Base of the Skull
GB20 is tucked into the two hollows at the base of the skull, just outside the large central neck muscles. It is one of the most useful points for relieving upper-facial tension and sinus pressure that often accompany sinus flare-ups. Hook your thumbs into the hollows, let your head gently tip back, and press upward toward the top of your head for about two minutes. This technique helps release built-up sinus pressure, especially when paired with slow, steady breathing.
ST3 — On the Cheekbone
ST3 sits directly below the pupil, in the small depression at the lower edge of the cheekbone. Because it lies almost directly over the maxillary sinus, gentle pressure here targets the referred pain caused by sinus pressure that reaches the upper molars. Use the tip of your index finger, press lightly for thirty to sixty seconds, and combine with slow nasal breathing if congestion allows to further reduce sinus pressure.
ST7 — Near the TMJ
ST7 lives just in front of the ear, in the depression you can feel when you open and close your mouth. It calms the jaw muscles that often co-contract during prolonged sinus pressure, making it especially helpful when discomfort spreads to the ear or TMJ region. Apply light, sustained pressure for about a minute, never deep or forceful, to gently relieve sinus pressure and associated jaw tension.
A Suggested 5-Minute Routine
- LI20 for 60 seconds
- Bitong for 30 to 60 seconds
- ST3 for 60 seconds
- GB20 for 90 to 120 seconds
- ST7 for 60 seconds

Adjunct Strategies That Amplify the Work
Acupressure works best as part of a small daily routine. We often recommend the following alongside the point work:
- Warm compress: A warm, damp cloth across the cheekbones for five to ten minutes thins mucus and softens the tissues.
- Steam inhalation: A bowl of hot (not scalding) water with a towel over the head, five minutes twice a day, supports mucociliary clearance.
- Hydration: Two to three liters of water daily keeps mucus thinner and easier to move.
- Sleep posture: Elevating the head of the bed or using an extra pillow helps gravity drain the sinuses overnight.
- Nasal saline rinses: Used as directed with distilled or previously boiled water, these can meaningfully reduce daytime pressure.
Dentist, ENT, or Acupuncturist: Who Should You See First?
The right first stop depends on the pattern. If the pain is isolated to a single tooth, triggered by biting or temperature, or accompanied by visible swelling of the gum, start with your dentist. If the pain involves several upper teeth, worsens when you bend forward, and follows a cold or allergy flare, start with your primary care physician or an ENT. If you have already ruled out acute infection and are dealing with recurring congestion, facial pressure, or clenched-jaw tension, an acupuncturist can add a different layer of care.
At Messina Acupuncture PC we frequently collaborate with local dentists and ENTs across Long Island when a patient’s picture crosses specialties. Our acupressure service and full acupuncture treatments are designed to complement, not replace, those evaluations.
When to See a Licensed Acupuncturist
If you have had a dental exam that came back clean, your ENT has cleared you of acute infection, and you are still living with facial pressure that radiates into the teeth or jaw, that is a reasonable moment to consider acupuncture. A licensed acupuncturist can assess the muscular, postural, and congestion-related drivers behind your pain and build a short plan around them. Our Setauket office sees a steady stream of patients with exactly this picture, and many tell us afterward that they wish they had come in sooner.
Frequently Asked Questions
Can a sinus infection really feel exactly like a toothache?
Yes. Because the roots of the upper back teeth share nerve supply with the maxillary sinus floor, inflammation in the sinus can produce pain that is indistinguishable from a dental problem. A dentist can usually rule out a tooth origin with an exam and a basic x-ray.
How long should I try acupressure before seeking care?
For a mild flare tied to a cold or allergy episode, a few days of acupressure, warm compresses, and hydration is reasonable. If pain is severe, one-sided, accompanied by fever, or persisting beyond ten days, see a clinician.
Is it safe to press these points during a fever?
Gentle, short sessions are generally fine, but a fever combined with facial pain, worsening symptoms, or colored nasal discharge should prompt a medical visit rather than more home care. Acupressure does not replace antibiotics when they are indicated.
Can acupressure help my TMJ pain too?
Often, yes. Because sinus pressure and TMJ tension frequently travel together, working points like GB20 and ST7 can ease both. If jaw pain persists once the sinus picture clears, a targeted TMJ plan is worth exploring.
Will acupuncture work better than acupressure?
For many chronic or recurring cases, in-office acupuncture delivers a more precise and sustained effect. Acupressure is an excellent bridge between sessions and a useful daily tool, but it is not identical to needle-based treatment.
