Persistent bad breath, also known as chronic halitosis, can be more than just a source of embarrassment. If brushing, flossing and using mouthwash aren’t making a difference, the cause might lie beyond your teeth. For many people, the nose, throat or sinuses may be the real culprits.
In this article, we explore the most common causes of bad breath related to the ear, nose and throat (ENT), including post-nasal drip, tonsil stones and sinus infections. We also explain when to see a specialist.
What ENT conditions can cause chronic bad breath?
While poor oral hygiene is a common cause of bad breath, it’s not the only one. Your upper airway, which includes the nose, sinuses and throat, may also be responsible.
Let’s take a look at some common conditions that may be causing chronic bad breath.
Post-nasal drip
If you’re constantly clearing your throat or feel mucus trickling down the back of it, you may have a post-nasal drip. This happens when mucus from the nose drips into the throat, creating an environment where bacteria thrive. The result is often an unpleasant smell or taste that doesn’t go away.
Post-nasal drip is often linked to allergies, colds or long-term sinus problems. If you notice a persistent bad taste despite good dental hygiene, this could be the reason.
Sinus infection
Recurring or long-term sinus infections can trap mucus and bacteria in the sinus cavities. This can produce a strong smell. Other symptoms may include facial pain, a feeling of pressure and nasal congestion.
This type of bad breath does not usually improve with mouthwash or chewing gum and may need medical treatment of the infection to go away.
Tonsil stones (tonsilloliths)
Tonsil stones are small white or yellow lumps that form in the crevices of the tonsils. They are made up of hardened bacteria, food particles and dead cells. Even with regular brushing and rinsing, they can cause a strong, unpleasant smell.
This condition is common in people who often experience tonsillitis, which is inflammation or infection of the tonsils.
Tonsil stones can often be gently removed at home using a cotton bud or gargling with warm water. However, persistent or large stones may require professional removal or, in some cases, consideration of a tonsillectomy (removal of your tonsils) if they’re recurrent.
Chronic throat infections
Frequent infections or inflammation of the throat or tonsils can also lead to bad breath. Pus, mucus or infected tissue may cause a lingering odour, even after the main symptoms have improved.
When should you see an ENT for bad breath?
It may be time to consult an ENT specialist if you:
- Have bad breath despite good dental hygiene
- Often experience sinus infections or post-nasal drip
- Notice white or yellow material in your tonsils
- Have repeated throat infections or sore throats
- Feel self-conscious about your breath and cannot find the cause
An ENT specialist can examine your nasal passages, sinuses and throat using a small camera and other comprehensive diagnostics. They can offer personalised treatments that go beyond what a dentist can provide.
