Oman today_ Chewing gum comes in various types, each with its own benefits and potential risks. For example, nicotine gums can help reduce the craving for cigarettes and alleviate withdrawal symptoms for those trying to quit smoking. Bubble gums, with their larger size and greater elasticity, are usually consumed for entertainment, while vitamin-enriched gums are particularly beneficial for children.
However, chewing gum is not without risks. Some studies suggest that certain gums and toothpastes may retain bacteria in the mouth that, over time, could contribute to heart problems. Chewing gum can also lower blood pressure and increase heart rate, which may be dangerous for individuals with heart conditions. Sweetened gums can trigger allergic reactions or irritate the digestive system. People with teeth filled with amalgam may ingest trace amounts of mercury when chewing gum excessively, although many researchers consider this amount to be harmless. Additionally, chewing gum before anesthesia or certain surgeries can be risky, and prolonged or vigorous chewing may damage the jaw joint or dislodge dental fillings.
On the other hand, chewing gum offers multiple benefits. Research indicates that it can improve working memory and enhance both short-term and long-term learning abilities. It also stimulates the frontal part of the brain’s cortex, activates the tongue muscles, and helps eliminate toxins from certain muscles. The addition of menthol to gum provides a cooling sensation and reduces thirst. Studies have shown that chewing gum can even help treat dry mouth caused by cancer. Gum chewing is effective in reducing acid reflux from the stomach to the esophagus and can prevent acid backflow while walking. Other research has found that it can reduce the pain associated with vaccinations in girls. Some gums even provide essential minerals, such as small amounts of salt, although the intake is limited. Sugar-free gums containing xylitol or sorbitol help suppress harmful oral bacteria and prevent tooth decay, making them beneficial for both children and the elderly. Furthermore, chewing gum after consuming foods or drinks with strong odors can help neutralize bad breath more quickly.
Overall, chewing sugar-free gum intermittently, rather than continuously, appears to have positive effects. Prolonged or habitual chewing is not recommended, and gum should not interfere with regular food intake or falsely reduce the sensation of thirst.
