Myths about chewing gumIn 1848 the American businessman John Curtis has adjusted production of chewing gum of own invention, and at the end of the XIX century the cud which as it was told in advertising, «prevents destruction of teeth» for the first time has been presented. Today's producers have nearby left from the predecessors because of what still build the advertising companies of the product on attempts to prove its utility for an oral cavity. The majority of people, despite of norms of moral and morals, actively ruminate everywhere: on the street, in transport, in cafe and restaurants, at schools and universities, on work. One fight against a fetid odour from a mouth, others try to "beat off" tobacco aftertaste, the third sacredly believe that prevent caries and restore acid-base balance. Children are involved by outer side of process: beautiful packs, ridiculous loose leaves, colorful chewing plates, variety of tastes. Meanwhile, it is well known that the cud contains many chemical additives, and at unreasonable use harms not only enamels of teeth, but also to health of a gastroenteric path.
The composition of chewing gum repeatedly changed producers while they have not stopped on a ratio of 20 % of a rubber basis to 60 % of sugar. Other components of a toffee are flavouring additives, dyes and the aromatic substances making together about 5 % from lump of a product. A significant amount of these substances, certainly, is added gradually and secretly, equally as is kept a secret and structure of each concrete taste and aroma. To an elastic band softening components help to keep elasticity: glycerine, lecithin and gum. Unfortunately, trees-kauchkonosov of which «in an ideal» the rubber basis of a cud is made, for mass production does not suffice, because of what producers use a synthetic material. According to the Test centre of polymeric footwear, medical and latex products of Russia, children's grades of a chewing delicacy are most dangerous in this regard. They more rigid, quickly lose taste and start to taste bitter. All this occurs because of the butadiyen-styrene rubber used here as a rubber basis. By the way, in our country it is forbidden, as causes headaches and loosens nervous system. Almost in each chewing gum producers add dyes. Often met on packing Е171 earlier also has been forbidden in Russia, but after has received eases. This dye call titanic whitewash, and now their use in foodstuff is admissible. The similar substance can cause diseases of a liver and kidneys. So, absolutely clearly that the structure of a cud is its main shortcoming. About what still it is necessary to know?
Oral cavity clarification. The cud cleans only a chewing surface of teeth, and the most dangerous zones in respect of caries in their intervals, unlike a toothbrush, leaves untouched. Besides, very often to an elastic band the food remains, and, for example, poor put seals or crowns stick at all.
Ph-balance. People should be trusted more to the organism which perfectly consults adjustment of Ph-balance of the oral cavity, what food they would not use. The unique merit of a cud in this case that she speeds up work of salivary glands which participate in process of normalisation of this balance. The cud to affect it cannot in any way, is equal as there is no direct link between ph-balance (individual for each person) and caries emergence.
Overload of okolozubny fabrics. Moderate chewing is useful for the person as in this case the pressure which is transferring from teeth in gums, promotes massage of fabrics and improves their blood circulation. The excessive hobby for a cud gives a boomerang effect, causing an overload of the described structures. It is fraught with development of inflammatory processes (a periodontal disease, гингвита), salivation increase with the subsequent violation of digestion. For this reason stomatologists recommend to chew fresh fruit, vegetables, rough bread from time to time to load and "mass" gums. The elastic band for such purposes is unsuitable.
Snow-white smile and fresh breath. It is one of the most important myths about the chewing gum, after all any of versions of this product is not capable to make a smile snow-white. To bleach teeth and to clear them of a scale it is possible only in an office of the doctor, the cud at all does not consult with it. This history - only an invention of resourceful experts in advertising. To refresh breath by means of a fragrant plate it is really possible, but the effect will be short-term.
Other side effects connected with mechanical influence of chewing gum:
• Destruction of seals, bridges, crowns and other stomatologic designs;
• Syndrome of a temporal and mandibular joint;
• Excessive development of chewing muscles;
• Increase in swallowed air (aerofagiya);
• The impassability of a trachea caused by a foreign matter from chewing gum;
• A foreign matter in a gullet or the thick intestines, capable to cause resistant locks or intestinal impassability.
Certainly, all listed does not mean that is necessary to refuse a cud completely. There are very many situations in which it can appear useful. For example, during travel on the car the cud rescues from an ukachivaniye and nausea, in the plane - prevents a mortgaging of ears at take-off or landing. By means of an elastic band it is possible to refresh quickly breath or to interrupt excessive appetite, keeping to a diet. The most important not to chew it too long, being limited, in an ideal, 2-3 minutes. In that case harmful effects of this "ambiguous" product on your organism will be minimised.
