Both of these factors result in less effective salivary cleansing and buffering. Periodontal disease is a causative factor of bad breath. Ask any dentist, the odor of gum disease can be so distinctive that a dentist can often correctly anticipate the presence of gum problems even before beginning their examination. Periodontal disease is second only to the accumulation of bacteria on the tongue as being the most common fundamental source of a person's bad breath. Since periodontal disease is usually more of a problem for person's over the age of 35 or so, the older we get the more likely that the source of our bad breath is related to conditions associated with our gums.
Periodontal disease is a bacterial infection located in the tissues which surround teeth.
Advanced forms of this disease can result in serious damage to the bone which holds the teeth in place. It is often the waste products from the bacteria which reside in these periodontal pockets, pockets which are often so deep that a person cannot effectively cleanse them, which can be the source of a person's bad breath. Sinus conditions can certainly influence breath odor. This discharge often has a foul taste and it is this drainage which can also foul the smell of one's breath. Contributing to their breath problems, persons with sinus conditions will often have stuffed up noses which in turn forces them to breath through their mouth.
