4 Main Causes of Halitosis (Bad Breath)
1. Imbalanced gut/mouth biome
It has been discovered that digestive health has an impact on oral health as well. The mouth is a part of your gut microbiome and home to your oral microbiome. Microbes, enzymes, and nutrients all pass through it on their way to your gut. Your gut has its own unique microbiome.
2. Having a sulphur-rich diet
Halitosis is caused by the excretion of the anaerobic bacteria that live within your mouth. These anaerobic bacteria (bacteria that do not need oxygen to survive) excrete sulphur compounds.
Garlic and onions are the first culprits that come to mind when we talk about bad breath, and yes, they are sulphur rich foods (that are also beneficial to your body). Meats, eggs, and other sources of protein are also rich in sulphur.
Gastric reflux may also contribute to having bad breath, as acids from your gut come back up into the oesophagus.
Cigarettes and cigars cause bad breath by leaving smoke particles in the throat and lungs even after the cigarette is put out. This effect is typical of nearly any tobacco product that involves inhaling smoke or rolling it around in the mouth. Thus the smell can linger for hours, giving off the stale sent associated with smoker’s breath.
Additionally, the chemicals in tobacco smoke can remain in the mouth, leading to a host of secondary causes of bad breath. The drying of the palate from tobacco use leaves a dry and chemical filled environment when oral bacteria can thrive.
4. Gum disease
When teeth and gums are not brushed, it is a perfect environment for bacteria to thrive and reproduce. Plaque and tartar become a medium for these bacteria which will lead to bad breath.
The good news is that good oral hygiene can reverse bad breath if gum disease is not in the advanced stage. A toothpaste that promotes natural salivation will reduce the acids in the mouth and the propagation of bacteria.
