Many of chewing gum is contraindicated.
The doctors explained how chewing gum can improve digestion and strengthen the enamel. And also, why it can not be chewed by pregnant women and those who have periodontal disease.
Chewed gum always. In Greece, the resin of the mastic tree, Siberian larch, in India and aromatic herbs. In the XVI century in Europe there is tobacco that is chewed and chewed until now.
Traditional plant species of gum carried multiple functions. They cleanse the oral cavity from food debris, disinfecting, strengthen gums and coached the masticatory apparatus. The first commercial chewing gum was made of vegetable raw materials, namely, resin of coniferous trees. This product is not widespread because of the unpleasant look. In addition, the gum met twigs and needles.
In 1869 he began experiments on the manufacture of gum rubber. In 1928, accountant Walter Dimer derived a new formula — it is similar to what is used now. It includes one part rubber and syrup from corn, one percent flavors or three of the sweeteners.
What is in chewing gum
The gum is produced mainly from synthetic polymers with the addition of other ingredients: sweeteners, flavorings, preservatives, vitamins and enzymes. Some gum can be active substances that contribute to teeth whitening and remonetization tooth enamel.
As sweeteners in children’s gum added sugar or glucose syrup. Sugar triggers the formation of bacterial film on the teeth. The bacteria Streptococcus mutans thrive in the formation of lactic acid. She, in turn, is secreted after cleavage of sucrose saliva. Bacteria also contribute to the accumulation in the oral cavity of the dextrin — he sticks to the tooth surface and forms insoluble plaque. And already in the RAID are beginning to act other bacteria that secrete acid and dissolve the hard tissue of the tooth. A number of scientists blames that sugar and other refined carbohydrates in a wide spread of caries.
In the gum for adults there are other sweet substances, which do not contain sucrose and have lower caloric value. However, the sugar substitutes cause a lot of controversy about their safety for humans.
Experiments on animals showed the following: aspartic acid — aspartame — may cause cancer and toxic to affect the blood vessels and nervous system. In chewing gum, aspartame is present in the minimum dosage, but if a person constantly uses chewing gum, this substance will accumulate in his body. As a result, it can disrupt the perception of reality. Xylitol acts as a laxative and also promotes the formation of kidney stones. Have a laxative effect sorbitol and isomalt.
All kinds of ballast substances in chewing gum too much. Although gum we vypilivaem its components for the most part still enter the body. Especially careful with chewing gum should be people with systemic diseases, kidney diseases, diabetes.
Chewing gum is strongly discouraged for pregnant women. It increases the risk of development of the fetus allergic reactions because of the ballast substances, which the immune system of the baby begins to struggle. It distorts the normal development of the immune system of the child.
What are the benefits of chewing gum
At the beginning of the XX century appeared the first studies about the benefits of chewing gum for digestion, nervous system and dental health. The publication of a Columbia University Professor of Hollingworth proves the following: the process of mastication reduces the total muscle tension and relieves stress. After this output the gum introduced in the compulsory rations of the US army.
A study by British psychologists from the University of Cardiff 8 Mar 2013 have proved that chewing helps you to concentrate on complex tasks for long periods of time. Participants in the study, chewing gum, showed the best results throughout the test rather than chewing, which at first had been more careful, but then lost concentration.
Chewing gum helps digestion. If you chew it after a meal it will help to strengthen salivation. Saliva cleans the teeth and interdental spaces from food residues and the bacteria it delivers to the enamel of nutrients, strengthens it.
Who can not chew gum
Chewing massages the gums and helps evenly load the entire dental camera that is good for the prevention of periodontal disease.
And it is prevention — if you already have periodontal disease, gum chewing is impossible. Chewing pressure is passed on to all teeth evenly. It is ensured by the circular ligament of the teeth so that no overload occurs. With periodontitis and periodontal disease these circular bundles are destroyed. As a result, the teeth are isolated, and the chewing pressure is transmitted vertically into the bone that surrounds each tooth. This compresses the blood vessels, the malnutrition and atrophy of the bone, laid bare the neck of the teeth, the teeth lose their stability and become even more mobile. Increased dental abrasion is another contraindication to the chewing gum.
Should not chew gum more than 10-15 minutes after a meal. Chewing on an empty stomach or more than 15 minutes can threaten the development of gastritis or stomach ulcers due to reflex selection acid, which occurs in contact with food in
the oral cavity. The stomach doesn’t know that gum spit out and not swallow.
What to replace gum
Chewing gum, in fact, has only one function — it removes leftover food after a meal, when you can’t brush your teeth. But now to do it outside the home is not such a problem.
Sold hygienic disposable toothbrushes with pre-applied toothpaste after brushing their teeth can be discarded.
In addition, with this task perfectly cope floss. If you are unable to use a toothbrush or floss after eating, rinse mouth with water. After consuming acidic drinks such as soft drinks and fresh juice, you should brush your teeth only 10 minutes — the acid softens the enamel, and mechanical cleaning damages it.
