Sinus Infection or Dental Pain?
Here’s How to Tell the Difference
Dental Emergency?
If you experience severe throbbing pain, swelling, or fever with dental pain, contact our Cardiff emergency dentists immediately.
Upper tooth pain and sinus infections share similar symptoms, making it challenging to determine the true cause of discomfort. At Emergency & Walk-In Dentist Cardiff, we frequently see patients who mistake one for the other. This comprehensive guide will help you identify the source of your pain, understand the key differences, and know exactly when to see a dentist versus a doctor.
Sinus Pain vs Dental Pain: Key Differences
Sinus Infection Signs
- Pain location: Affects multiple upper teeth on one side
- Pain type: Dull, constant pressure that worsens when bending over
- Additional symptoms:
- Nasal congestion
- Post-nasal drip
- Headache behind eyes
- Reduced sense of smell
- Triggers: Often follows cold or allergies
- Duration: Typically lasts 7-10 days
Dental Problem Signs
- Pain location: Isolated to one specific tooth
- Pain type: Sharp, throbbing pain when chewing or with temperature changes
- Additional symptoms:
- Tooth sensitivity
- Visible decay or damage
- Swollen gums
- Bad taste in mouth
- Triggers: Biting, sweets, hot/cold foods
- Duration: Persists until treated
The Sinus-Tooth Connection
The maxillary sinuses sit directly above your upper back teeth. When inflamed, they can:
Press on tooth roots causing referred pain
Create confusion about pain source
Mask actual dental problems
Pro Tip: Gently tap on your suspected tooth. If it’s dental pain, this will likely intensify it. Sinus pain typically won’t worsen with this test.
What’s Causing Your Pain? A Simple Guide
Do you have nasal congestion, headache, or recent cold?
✅ Yes → Likely sinus-related
• Try decongestants and steam inhalation
• See GP if no improvement in 7 days
❌ No → Likely dental-related
• Check for visible cavities or damage
• Schedule dental exam within 3 days
When to See a Cardiff Dentist
Schedule an emergency dental appointment if you experience:
Severe Throbbing
Constant, intense pain that disrupts sleep
Visible Damage
Cracked, chipped, or discolored tooth
Gum Symptoms
Swelling, pus, or pimple-like bumps

Note: 35% of sinus-related tooth pains still warrant dental evaluation to rule out co-existing issues.
Possible Dental Causes of Upper Tooth Pain

Sinus vs Dental Pain FAQs
Q: Can sinus pressure make a healthy tooth hurt?
A: Yes, sinus inflammation can cause pressure on the roots of perfectly healthy upper teeth (especially molars and premolars). This is called “referred pain” and typically:
- Affects multiple teeth on one side
- Creates a dull, constant ache
- Worsens when bending forward
Q: How can I tell if my toothache is actually a sinus infection?
A: Try these simple tests at home:
- Bend forward test: If pain increases when you bend over, it’s likely sinus-related
- Tooth tap test: Gently tap on the painful tooth – if it’s extremely sensitive, it’s probably dental
- Cold test: Drink cold water – if it triggers sharp pain, the tooth is likely the source
Q: Can a sinus infection cause dental problems?
A: While uncommon, chronic sinus infections can potentially lead to:
- Sinus tract infection: Where infection drains through gum tissue
- Increased grinding: Due to sinus discomfort, causing tooth damage
- Dry mouth: From mouth breathing, increasing cavity risk
