A dull ache in your upper teeth can be difficult to explain, especially during allergy season or a cold. You may feel pressure around your cheeks, tenderness near your nose, or discomfort when chewing. These symptoms can result from inflamed sinuses, but a dental infection may cause similar pain.
Knowing the differences may help you recognize when to seek dental care and avoid delaying treatment for a potentially serious infection.
How Can Sinus Pressure Cause Tooth Pain?
The maxillary sinuses are air-filled spaces located above the upper back teeth. When a cold, seasonal allergy, or sinus infection causes inflammation, pressure may develop in this area. Because the roots of some upper teeth sit close to the sinus floor, this pressure can create an ache that feels as though several teeth hurt at once.
Sinus-related tooth discomfort often affects multiple upper teeth rather than one specific tooth. You may also experience nasal congestion, a runny nose, facial pressure, or a reduced sense of smell. The discomfort may become more noticeable when bending forward, although this symptom alone cannot confirm a sinus problem.
Sinus pressure generally improves as the underlying congestion settles. Persistent or worsening symptoms still deserve medical assessment.
What Are the Signs of a Tooth Infection?
A tooth infection may develop when bacteria enter the inner pulp through deep decay, a crack, or damage to the tooth. If the infection spreads to surrounding tissues, it may cause a dental abscess.
Unlike typical sinus-related discomfort, a tooth infection may produce several more focused symptoms:
- Localized pain: One tooth may hurt more than the surrounding teeth.
- Temperature sensitivity: Hot or cold foods may trigger discomfort that lingers after the temperature stimulus is removed.
- Pain when biting: Pressure on the affected tooth may cause sharp or persistent pain.
- Gum changes: Swelling, redness, or a small pimple-like bump may appear near the tooth.
- Unpleasant taste: Drainage from an abscess may cause a bad taste or odour.
Some dental infections develop with relatively mild pain, so the absence of severe discomfort does not rule them out. A dental examination is necessary to determine the cause.
How Can You Tell Which Condition You Have?
The location of pain, accompanying symptoms, and dental history provide useful clues, but they cannot establish a diagnosis on their own. Sinus inflammation and dental disease can also occur together.
A dental professional may examine your teeth and gums, test the affected teeth, and take dental X-rays when clinically indicated. If the findings suggest a sinus problem rather than a dental cause, medical assessment may be recommended.
If you are experiencing unexplained upper-tooth pain, dentists in Newmarket can assess whether a dental condition may be contributing to your symptoms. A family dentist in Newmarket may also help identify decay, cracked teeth, or gum problems during routine or symptom-focused examinations.
When Should You Seek Urgent Care?
Do not ignore severe or increasing tooth pain, facial swelling, or a suspected dental abscess. Contact a dental professional promptly if these symptoms develop. An emergency dentist in Newmarket may assess urgent dental concerns and determine whether treatment is needed.
Seek emergency medical care if swelling affects your eye or neck, you have difficulty breathing or swallowing, or you develop significant facial swelling with rapidly worsening symptoms.
