Understanding Bad Breath and Curing It, Naturally

Being greeted by a waft of bad breath is not something pleasant. Unfortunately, bad breath is a common occurrence among many — be it those convinced they have foul breath or those who do have terrible breaths and don’t know it. If your suspicions are confirmed and you do have bad breath, fear not for there are many home remedies that can eliminate foul mouth odour.

The Origins of Bad Breath

Normally, bad breath originates from the mouth, where bacteria is ever prevalent. This is completely normal as when we eat bits of food get stuck in your teeth and bacteria tends to thrive on these, releasing foul-smelling sulphur compounds.

Poor dental hygiene is usually attributed to the most common cause of bad breath. Things worsen if you neglect to brush and floss often, subsequently leading to the growth of the bacteria in your mouth, creating a thin film of bacteria known as plaque. When plaque isn’t brushed away at least twice per day, it produces a foul odour and leads to another smelly process, tooth decay.

All foods get stuck in your teeth, but certain foods like onions and garlic more commonly lead to bad breath. Digestion of these foods releases sulphur compounds into your bloodstream. When the blood reaches your lungs, it affects your breath.

There are instances when the source of mouth odour originates from other parts of the body, like the stomach. It could be a result of acid reflux, which leads to the partial regurgitation of foul-tasting liquid that causes the nasty smell or infections, diabetes complications and renal failure. Starting a new diet, such as the keto diet, may also bring about a certain breath odour.

What You Eat Effects Your Breath

When you eat, food begins to break down in your mouth. Consuming food with a strong odour (such as garlic or onions) doesn’t go away until the food have passed through your digestive tracks and out it goes. Brushing and flossing, even gargling mouthwash are merely temporary solutions.

Poor Dental Hygiene = Bad Breath

Why do poor habits cause bad breath? The answer to this question is simple and based of facts. When you don't brush and floss your teeth daily, food particles get caught in your mouth, promoting bacterial growth between teeth, around the gums, and on the tongue which subsequently results in bad breath. In addition, odour-causing bacteria and food particles can cause bad breath if dentures are not properly cleaned. Bad habits such as smoking or chewing tobacco-based products not only stains your teeth, reduce your ability to taste foods, and irritate your gums, it also causes mouth odour.

Pineapple juice

There are many people who swear by the treatment of pineapple juice against mouth odour. There isn’t scientific evidence to back up this theory, however, anecdotal reports suggest that it works.
