What causes Halitosis? The dentist can determine whether halitosis is the result of bad oral habits or something more serious. Causes of bad breath include a wide array of conditions, medically and from personal habits. Typically, the types of foods consumed: garlic, onions, cheese and dairy will leave an unpleasant odor. During the digestion process these foods release offensive gases. These gases can be released for up to 24 hours after initial consumption.
Likewise, any food left partially undigested in the stomach begins to release distasteful odors. The senior population is especially susceptible to this. With age, the body begins to have more and more difficulty breaking down the contents of a meal.
Medical conditions such as sinusitis, diabetes and kidney problems can all result in seriously bad breath. Odors include the smell of rotting eggs, a fishy or ammonia smell (severe kidney failure) or the sweet smell of fruit (diabetic ketoacidosis).
Lifestyle choices can result in halitosis as well. Both smoking and drinking can contribute to dry mouth. The lack of saliva can also cause bad breath. A tongue scraper can aid in ridding your mouth of any unpleasant smells coming from your tongue.
