And like other decomposing matter on earth, food particles inside our mouth emit unpleasant odor. Food particles that remain in between teeth can lead to plaque buildup and tooth decay. Plaque buildup emits bad odor. Tooth decay can open some spaces around the dentures that will accommodate more food particles that can cause bad breath, not to mention the odor the decaying teeth emits. It is more often the reason to children since they have habits of sucking objects including blanket that quickly dries the mouth. For adult, dried mouth is often caused by poor saliva production and using mouthwash that contains too much alcohol. Nasal, throat, and mouth infection cause halitosis as well. At first there you can argue that dairy products are rich in protein. But this is where the problem starts. Bacteria in the mouth break down protein to produce VSCs. And the more protein in your mouth, the more VSCs created. It should be cleared though that you are not discouraged to eat or drink diary product but if you have chronic bad breath, try to lessen your intake or better yet, clean your mouth immediately after eating or drinking any dairy product. Simply put, bad breath occurs when food particles remain inside your child's mouth. To prevent bad breath from happening, there are 4 basic things you should do as a parent or guardian: 1. Teach your child the proper oral hygiene. The best way to do it is by brushing your teeth together. Also, allow your child to choose the toothbrush and toothpaste he wants to use. While antibiotics are good options, they are seldom used in curing bad breath. This is largely because the sulfur-producing oral bacteria could in time, get immune with the effects of the antibiotics. Thus, you would only move from one does to another without truly alleviating the condition. Thus, you must go after long term cures. It might be due to some foods or beverages you have taken recently or certain medications for which the by products of decomposition are emanating through your mouth. But, what if yours is a chronic condition? What would you do? For one, bad breathe would not have been there if you were careful enough to observe proper oral hygiene.
