Sinus pressure and congestion can sometimes radiate pain into your upper teeth that feels like a toothache. This referred pain happens because the roots of upper back teeth sit directly below sinus cavities.
While the tooth itself is healthy, excessive sinus pressure can make it extremely sensitive and painful.
Trying to ignore sinus-related tooth pain only leads to unnecessary suffering. Thankfully, there are effective ways to relieve the tooth pain caused by sinus pressure.

How Sinus Pressure Causes Tooth Pain
The maxillary sinuses are located above the upper teeth, beneath the eyes. When these sinuses get obstructed and inflamed due to illness or allergies, they can exert pressure downward onto the teeth.
Here’s why this happens:
Shared nerve pathway
The nerve that serves the upper teeth also registers sinus pain signals, so the brain is confused.
Pressure on tooth roots
Swollen sinus tissue puts direct pressure on exposed tooth roots.
Referred pain
The brain thinks sinus pain signals originate from the teeth themselves.
No matter the cause, sinus pressure hitting upper teeth can make them sensitive and painful. It’s important to alleviate the sinus pressure rather than assuming you need a root canal.
Tips to Relieve Sinus-Related Tooth Pain
Use these methods to find relief from tooth pain due to sinus congestion and pressure:
1. Oral decongestants
Oral decongestants like pseudoephedrine can be a game-changer. They work by reducing sinus swelling and drainage, easing the pressure on your teeth. Consult a healthcare professional before use, especially if you have underlying health conditions.
2. Nasal irrigation
Rinsing nasal passages with a saline flush effectively removes mucus and allergens, offering immediate relief from sinus congestion affecting dental comfort. Regular use can maintain clear sinuses and prevent tooth pain.
3. Steam Inhalation
Inhaling warm, humid air through steam inhalation helps loosen mucus, clearing sinus pressure and providing relief from tooth pain linked to sinus congestion. Regular sessions promote healthy sinuses.
4. Warm Compress
Applying a warm washcloth to your face opens up sinus passages, reducing congestion and easing pressure on teeth affected by sinus-related discomfort. This soothing method can be applied multiple times a day.
5. Hydration
Staying well-hydrated thins out mucus discharge, preventing excessive sinus drainage. Proper hydration is essential for maintaining clear sinus passages and reducing tooth pain linked to sinus issues. Aim to drink at least eight glasses of water daily.
6. Dental Buffer Paste
Applying dental buffer paste to sensitive teeth acts as an insulator, shielding them from triggers that cause pain. This paste provides a protective layer, reducing discomfort associated with sinus-related tooth pain. Consult your dentist for recommended products.
7. Over-the-Counter Pain Relievers
Over-the-counter medications like ibuprofen can provide temporary relief from sinus tooth pain by reducing inflammation and discomfort. Follow the recommended dosage guidelines and consult a healthcare professional if you have concerns.
8. Oral Antihistamines
If allergies contribute to sinus pressure and tooth pain, oral antihistamines can be effective. These medications reduce swelling caused by allergies, providing relief from sinus-related discomfort in the teeth. Consult your healthcare provider for suitable antihistamine options.
See Your Dentist if Symptoms Persist
Be sure to consult your dentist if sinus-related tooth pain lingers for over 2 weeks or increases despite home treatment. A dentist can examine your mouth and dental X-rays to rule out any underlying oral health issues that may be contributing to sinus congestion and discomfort.
In some cases, a root canal may be required if sinus pressure causes irreversible pulp inflammation. But in most situations, relieving the sinus obstruction will eliminate referred tooth pain. Get long-lasting relief by addressing the root cause with help from your dentist and doctor.
Final Thoughts
Upper tooth sensitivity triggered by sinus pressure doesn’t have to leave you in agony. Use oral decongestants, nasal irrigation, hydration and dental buffer pastes to alleviate sinus pressure hitting the tooth roots. Combining dental and medical treatments will help resolve sinus-related tooth pain for good.
However, if the pain persists or worsens, it’s crucial to seek professional dental or medical advice for proper evaluation and tailored treatment.
