Can A Sinus Infection Cause Bad Breath?

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 longer than three months.

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 odor from the infection transfers to your breath.

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, acetaminophen, 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 the Mayo Clinic, you should schedule an appointment with your doctor if you are experiencing sinusitis symptoms for more than ten days. He or she may prescribe antibiotics. Talk to your doctor if you get sinus infections often. He or she may want to do additional tests to find out why.

You can help improve the smell of your breath by brushing twice a day with a fluoride toothpaste.

If you feel under the weather and are experiencing upper respiratory symptoms and having issues with bad breath, check with your physician to see if a sinus infection is the cause.
