Halitosis or bad breath
What is halitosis?
Halitosis is the scientific term (medical) "bad breath". It is that man smells as unpleasant and realizes that emerge from the oral cavity. These odors are a group of volatile sulfur compounds (CSV) and the hydrogen sulfide and methyl mercaptan (rotten egg smell).
It is possible to scientifically and objectively measure odors originating from the oral cavity, including by means of appropriate measuring devices to record the concentration of sulfur molecules. Technically, the boundary between fresh breath and bad is about 75 ppb (parts per billion). So the people who produce an unpleasant odor all day (a phenomenon that clearly perceives its environment) suffer from "halitosis" or "chronic halitosis". Scientific studies have shown that approximately 30% of the population complains of halitosis. If you have a fresh taste, do you also smell fresh? Unfortunately not. You can get in the mouth a pleasant mint flavor, while your colleague perceives your breath an unpleasant odor of sulfur. The sense of smell and taste are two totally different ways almost like seeing and hearing. We are not able to tell our own bad breath by blowing into their hands cupped over his mouth to breath and smell (all you smell is the smell of your hand). The human body is "designed" so that he can not perceive their own fragrances. It is a biological process called acclimatization, which is essential to enable us to smell things in nature other than ourselves. There are some symptoms that generally indicate the presence of "halitosis" (bad breath), which we address in another chapter.
Symptoms of bad breath
Because halitosis originates in the mouth, it is hardly possible to be aware of this problem through their own taste or smell. You may notice an acid or bitter taste in the mouth or see a white coating on the back of the tongue. Many times, however, does not discover this problem until a family member, colleague or friend you know. The most common symptoms are:
• white coating on the tongue
• Note that brushing and flossing do not help
• Dry mouth, thick saliva, burning tongue
• Unpleasant taste in the morning
• White bits in the tonsils
• Worse after consuming dairy products
• Worse after drinking alcohol, coffee or sweets
• People in their environment offer gum or mints often
• People turned away or takes a step back
• Taste sour, bitter or metallic persistent
