Can a Sinus Infection Cause Tooth Pain?
Many people are surprised when they feel tooth pain during a sinus infection. It can feel very similar to a dental problem, making it difficult to know whether you should visit a dentist or a doctor.
The short answer is yes — a sinus infection can cause tooth pain, especially in the upper back teeth.
Understanding why this happens can help you determine the right treatment and avoid unnecessary discomfort.
Why Sinus Infections Cause Tooth Pain
Your upper molars are located very close to the maxillary sinuses, which are air-filled cavities located behind your cheeks and above your teeth.
When these sinuses become inflamed due to infection or congestion, pressure builds up inside the sinus cavity. This pressure can press down on the roots of the upper teeth, creating pain that feels like a toothache.
This is why many people with sinus infections experience:
-
aching in the upper teeth
-
facial pressure around the cheeks
-
headache or sinus pressure
-
nasal congestion
-
tenderness when biting down
The pain may affect several upper teeth at the same time, which is a clue that the problem may be sinus-related rather than a single damaged tooth.
How to Tell the Difference Between Sinus Pain and a Tooth Infection
It can sometimes be difficult to distinguish between dental pain and sinus-related discomfort.
Signs the pain may be caused by a sinus infection
-
Pain affects multiple upper teeth
-
Pressure increases when bending forward
-
You have sinus congestion or a runny nose
-
Facial pressure around the cheeks or eyes
-
Symptoms improve as sinus congestion improves
Signs the pain may be caused by a dental problem
-
Pain is limited to one tooth
-
Sensitivity to hot or cold
-
Swelling around a tooth or gum
-
Pain when chewing on a specific tooth
-
Persistent pain without sinus symptoms
If you are unsure, a dental examination can quickly determine whether the pain is coming from the teeth or the sinuses.
When to See a Dentist for Tooth Pain
Even if you suspect sinus pressure is causing the discomfort, it is important not to ignore tooth pain.
Dental problems such as:
-
tooth infections
-
cracked teeth
-
cavities
-
abscesses
can produce symptoms that feel similar to sinus pain.
A dentist can examine your teeth and take digital X-rays to rule out dental causes.
Treating Sinus-Related Tooth Pain
If the tooth pain is caused by a sinus infection, treating the sinus problem usually resolves the dental discomfort.
Common treatments include:
-
nasal decongestants
-
saline nasal irrigation
-
antibiotics (when bacterial infection is present)
-
anti-inflammatory medications
-
rest and hydration
As sinus pressure decreases, the pressure on the tooth roots also disappears.
