Gingivitis & Bad Breath From the Nose

By Tara Thackeray ; Updated August 14, 2017

Bad breath can ruin interviews, dates and first impressions. Previously, doctors thought that bad breath is untreatable; however, with the right diagnosis the problem can be cured. Bad breath may come from either the mouth or nose. When gingivitis is the source of bad breath, however, it develops in the mouth.


Gingivitis, a mild gum disease, often goes undetected. Poor oral health care causes gingivitis. Plague builds up on your teeth, bacteria grows and the disease forms. Brushing and flossing your teeth regularly prevents gingivitis. Common symptoms of the disease include swelling, gum discoloration and bad breath.


When gingivitis occurs it causes bad breath from the mouth. The disease begins in your gums and spreads the odor throughout your mouth. The tongue absorbs this odor and harbors it until you speak. When you use your tongue to talk, the aroma is sent into the air others can smell it.

According to Bad Breath Guide, only 5 to 10 percent of people suffering from bad breath have it originate in their nose. Nearly impossible to tell by yourself, the best way to determine if bad breath comes form your nose is to ask a good friend or family member to help. Simply breathe out through your nose, and the person can confirm or deny if you have bad breath from your nose.

Reasons Behind Bad Breath from Nose

According to the British Dental Association, if a foul odor comes from the nose, it can indicate a serious illness. Such illnesses may include a sinus infection, a foreign object in the nose, or blocked air or mucus flow. A blockage prevents air from traveling successfully within your nose, which creates a bad smell. If bad odors do come from your nose and not your mouth, consult a doctor.


Preventing bad breath and gingivitis requires establishing a healthy routine. First, brush your teeth twice a day and floss your teeth once a day. Toothpaste that contains fluoride fights bacteria and plague more effectively. Be careful what you eat, fruits and vegetables promote good breath, while tobacco and alcohol can attribute to the opposite. Last, visit a dentist twice a year to check up on both gingivitis and bad breath.
