You already don't feel your best, and then you notice (or someone mentions) that you have bad breath. Did you know that bad breath can be a tell-tale sign of a sinus infection? It’s true. That’s what happens when you have sinus drainage in the back of your throat. It’s not pleasant, but it is treatable, and when the infection is gone, so is the bad breath associated with it. Here’s what you should know and can do.

What Are Sinus Infections?

Sinus infections occur when there's a fluid build-up in your sinuses. Germs grow.

Colds, allergies, smoking or exposure to second-hand smoke, a weak immune system and structural problems in the sinuses can all cause sinus infections.

Symptoms include: a runny and/or stuffy nose, facial pain or pressure, headache, postnasal drip, sore throat, cough and bad breath. Acute sinusitis lasts less than four weeks, whereas chronic sinusitis may last for longer than three months.

How Do Sinus Infections Make Bad Breath?

The mucus in infected sinuses smells bad. Infected mucus drips out of the sinuses and down the back of the throat, where it meets the air you exhale, and the odour from the infection transfers to your breath.

How Do You Treat A Sinus Infection?

Many acute sinus infections clear up on their own. Symptoms can be soothed with over-the-counter (OTC) treatments such as antihistamine tablets, nose sprays, paracetamol and throat lozenges. Avoid using nasal decongestants for longer than three to five days. Drink plenty of (hot) liquids, use a humidifier and spray nasal saline as needed.

According to this DoctorxDentist article on sinus, you should visit a doctor if you have cold/flu-like symptoms that have not resolved themselves within 7-10 days or is getting worse on the third to fifth day of your illness. They may prescribe antibiotics. Talk to your doctor if you get sinus infections often. Additional tests may be done to find out why.
