The way your breath smells says more about you than oral health alone. While we clean our teeth to get rid of that awful morning breath, this smell could be telling you about your overall health.

Here are some reasons why your breath may smell and what you can do about it.

Snoring and Sleep Apnea

If you snore or sleep with your mouth open, it can get dry, making it an even better home for the bacteria that create “morning breath”. Snoring is a symptom of sleep apnea. If you snore frequently, talk to your doctor about avoiding the dental and medical complications that apnea can cause.

Gum Disease

If you have a metallic smell on your breath, you may have bacteria developing behind your gum line, which can cause inflammation and infection. If you smoke or don’t brush and floss regularly, you’re more likely to get it. 

Acid Reflux

It can make your breath smell sour and force food or drink into your mouth. The acid can also harm your throat and mouth, creating a breeding environment for more odorous germs.


Having a sweet-smelling breath might also become alarming as having a sour-smelling breath. If your toothpaste or mouthwash doesn’t cause an unpleasant odour, you should consult your physician. People with diabetes produce insufficient insulin to control blood sugar levels. This could leave you with a weird smell on your breath, similar to acetone or fruit alcohol. If left untreated, ketoacidosis can be lethal.

Allergies and Sinusitis

If you suffer from seasonal allergies, bad breath may signify that the seasons are changing, and it’s time to stock up on allergy medication. Foul-smelling breath can be caused by post-nasal drip, mucus build-up, or respiratory illnesses. 

Tooth Decay and Gum Disease

Tooth decay and gum disease are two of the most common causes of bad breath. Bacteria can sometimes infiltrate the layers of your teeth, especially if you’ve recently had a filling or a chip in your tooth. Maintain a good hygiene routine to stop getting any gum disease and bad breath.
