5 Main Causes Of Bad Breath

Having bad breath can decrease our confidence in everyday communication. Mouth odor is a touchy issue that isn’t talked about much and rarely treated properly even though it’s a very common problem. Knowing what causes mouth odor is the first step to treating it, and here are the main causes of having bad breath.

Bad breathBad hygiene

If you don’t brush your teeth well enough it can leave a film of bacteria built up on the surface of the teeth. This can potentially block out the salivary glands in your mouth and creates the perfect environment for bacteria to reproduce, which leads to mouth odour.

Other than that, bad dental hygiene can also cause gingivitis which if not treated can develop to periodontitis. This is the main reason for mouth odour and many other health problems like receding gums, loose teeth and tooth loss.

Mouth infection

Infection and cavities are a great conditions for bacteria to grow and reproduce. Disintegrating food left on cavities can cause unpleasant breath.

2Respiratory infection

Past sinus infection, sore throat, tonsillitis patients may experience mouth odour as well. Especially for cases of tonsil stones, bad breath most often comes out when coughing.

3Digestion problems

Gastroesophageal reflux, gastritis, eructation, constipation,… and other digestion problems can be associated with mouth odor.

4Smelly food

When you eat garlic, onions, spoiled tofu, curry or drink alcohol regularly, smoke… those things affect your breath as well. Apart from that, cancer patients who go through chemotherapy or cirrhosis, kidney failure patients can have problems with mouth odour.
