Sinusitis, also known as a sinus infection, is the inflammation of the sinus cavities lining the nasal passages. These cavities produce mucus, which helps humidify our air and filter out pollutants. However, when these cavities become inflamed due to infection, allergies, or other factors, they can lead to sinusitis.

Symptoms of Sinusitis:

Sinusitis can manifest through a variety of symptoms, including:


  • Facial pain and pressure, particularly around the forehead, cheeks, and eyes.

  • Nasal congestion and difficulty breathing through the nose.

  • Thick, discolored nasal discharge.

  • Headaches, particularly in the forehead region.

  • Sore throat and coughing, often due to postnasal drip.

  • Reduced sense of smell and taste.

  • Fatigue and overall discomfort.


Most interesting thing is sinusitis can often be mistaken for toothache. Patients experiencing sinusitis may struggle to pinpoint the exact source of their pain, leading to confusion and frustration. The proximity of the sinus cavities to the upper teeth can result in referred pain, making it challenging to distinguish between sinusitis and dental issues. As a result, individuals may seek dental treatment when the underlying cause lies in sinus inflammation. This highlights the importance of consulting dentists to accurately diagnose and address sinusitis, especially when symptoms overlap with other conditions like toothache.

Causes of Sinusitis:

Several factors can contribute to the development of sinusitis, including:

  • Viral infections, such as the common cold or influenza.

  • Bacterial infections, which may occur as a complication of a viral infection or independently.

  • Allergies to pollen, dust, pet dander, or certain environmental irritants.

  • Structural abnormalities in the nasal passages, such as a deviated septum or nasal polyps.

  • Immune system disorders that affect the body's ability to fight infections effectively.

  • Chronic conditions like asthma or cystic fibrosis, which can increase susceptibility to sinusitis.


Treatment Options for Sinusitis:

The treatment of sinusitis often depends on its underlying cause and severity. Some common treatment options at Quek And Me Dental Surgery include:
