Everyone knows bad breath is not ideal. While bad breath can often be eradicated by a quick mouth rinse or teeth brushing, some continue to suffer from it despite their proper oral hygiene. There are some issues and habits which lend themselves to bad breath despite the measures taken. Here are some examples:

Ketogenic Diet

A ketogenic diet, or one that is low in carbohydrates, is often accompanied by bad breath as a side effect. The diet is high in protein, which are broken down by the body at a much higher rate that carbohydrates. The bad breath comes from the extra protein after it has converted to amino acids. The amino acids will then go through a chemical process which increases hydrogen sulfide. Sulfur, or any chemical property including sulfur, has a rotten egg scent, which causes bad breath. While this process occurs with any type of diet, it is much more prevalent in diets low in carbohydrates.

Dry Mouth

Dry mouth is an issue many people suffer from. This is a true medical condition and requires treatment. Unfortunately, dry mouth also causes chronic bad breath. Dry mouth is a lack of the normal amounts of saliva in the mouth. Saliva is a natural moistening substance that is used to remove bacteria from the mouth. When the mouth is dry for a long period of time, the mouth suffers a lack of oxygen and adds to the problem. In addition to medical contributions, dry mouth can also be caused by medications you take, alcohol use, and smoking.

Respiratory Infections

Bad breath can also accompany those who suffer from respiratory infections. The infection stems from a mucus buildup in the throat. This situation can provide the perfect environment for bacteria growth. Bacteria growth will always equal bad breath. To get rid of chronic bad breath with a respiratory infection, be sure to gargle a mouthwash that includes an antiseptic. This will help rid the mouth of the bacteria, but it also helps the bad breath problem. Gargling in this manner could also help heal your infection more quickly since you are ridding the source of the infection.

Make sure you always have a good oral hygiene routine in place, including daily brushing and flossing. If you have chronic bad breath despite your good oral hygiene, you need to see a dental clinic right away to rule out any underlying problems that can cause other health problems.
