Can an Infected Tooth Cause Sinusitis?

Did you know that an infected tooth can sometimes cause symptoms that feel like sinusitis?

At Ledismile Dental Clinic in Tirana, we often explain to patients that not every sinus problem starts from a cold, flu or allergy. In some cases, the real source may be an untreated dental infection.

This condition is called odontogenic sinusitis. It happens when an infection from the upper back teeth, especially the molars and premolars, spreads toward the maxillary sinus.

Why Can a Tooth Infection Affect the Sinus?

The roots of the upper molars and premolars are located very close to the maxillary sinus. When a tooth infection is left untreated, bacteria and inflammation can move beyond the tooth root and irritate or infect the sinus area.

This is why a patient may feel sinus pressure, nasal blockage or facial discomfort, even when the main problem is actually dental.

What Is Odontogenic Sinusitis?

Odontogenic sinusitis is a sinus infection that originates from a dental problem. Unlike common sinusitis, which is often related to viral infections, allergies or respiratory conditions, odontogenic sinusitis starts from the teeth or surrounding dental tissues.

The most common dental causes may include:

• Untreated deep cavities
• Infected tooth roots
• Dental abscesses
• Failed or old root canal treatments
• Advanced gum infection around upper back teeth

Symptoms You Should Not Ignore

A tooth-related sinus infection can be confusing because the pain is not always clearly connected to one specific tooth.

Common signs may include:

• Pressure or heaviness in the face
• Blocked nose that does not improve
• Bad taste in the mouth
• Nasal discharge
• Unpleasant smell from the nose or mouth
• Pain in the upper jaw or cheek area
• Discomfort that does not clearly come from one tooth

If these symptoms are persistent, one-sided or keep returning, a dental evaluation may be necessary.

Why Antibiotics Alone May Not Be Enough

One of the most important things to understand is that odontogenic sinusitis usually does not resolve completely if only the sinus symptoms are treated.

Antibiotics may reduce inflammation temporarily, but if the infected tooth remains untreated, the problem can return.

The real solution is to identify and treat the dental source of the infection.

How Is Tooth-Related Sinusitis Treated?

Treatment depends on the condition of the tooth, the severity of the infection and the involvement of the sinus.

In many cases, the dental treatment may include:

• Root canal treatment to clean and save the infected tooth
• Tooth extraction when the tooth cannot be saved
• Professional dental imaging to evaluate the tooth and sinus area
• Collaboration with an ENT specialist when sinus involvement is more advanced

By treating the infected tooth, the sinus has a much better chance to heal properly.

Why Early Diagnosis Matters

Ignoring a dental infection can allow bacteria to spread deeper into surrounding tissues. What begins as a small cavity or an untreated root infection may develop into a more complex oral and sinus problem.

Early diagnosis helps prevent complications and allows the dentist to choose the most conservative treatment possible.
