Do you worry about your bad breath? Bad breath can be embarrassing and can cause a lot of anxiety. I know it’s just as important to know what causes bad breath as it is to know how to treat it. Bad breath is mainly caused by a buildup of bacteria in the mouth that can cause a bad smell. Poor oral hygiene, untreated gingivitis, untreated or advanced periodontal disease, cavities, and smoking can cause bad breath. Other causes can be your diet which may include garlic and onions that can cause temporary bad breath until they are absorbed in the blood and expelled by your breath. Dry mouth due to side effects from being on multiple medications, from being a mouthbreather, something that happens naturally as we get older as our saliva production and saliva flow decreases. Sometimes, bad breath can be a sign of a more serious medical problem such as diabetes, kidney disease, or liver disease so it’s really important not to ignore bad breath and to seek treatment.
