Precautions for chewing gum:
First, try to choose sugar-free or xylitol chewing gum.
Cariogenic bacteria in the oral cavity can use sucrose to produce acidic substances, which in turn corrode teeth. Xylitol can't be used by cariogenic bacteria, and it can't provide nutrition for bacteria to live on. At the same time, xylitol can help early dental caries and can play a role in natural restoration, so it can prevent dental caries. The higher the xylitol content in chewing gum, the better the caries prevention effect.
Second, choose chewing gum after meals and snacks.
After eating sugary foods and drinks, the acidity of dental plaque in the mouth increases. At this time, chewing sugar-free or xylitol chewing gum can stimulate saliva secretion, neutralize acidic substances and contribute to tooth remineralization.
Third, don't chew gum for too long.
Chewing gum for a long time, the masticatory muscles are always in a state of tension, and it is possible to develop the habit of grinding teeth at night. In addition, if teenagers chew gum during their physical development, it may make the masseter muscle over-exercise, stimulate the muscle and bone development of the mandibular angle, and finally present a "square Chinese face" in appearance, affecting women's facial shape. Therefore, chewing gum should be controlled within a quarter of an hour each time.
Fourth, it is best not to chew gum if you have filled your teeth.
People who have filled their teeth with mercury-containing materials had better not chew gum. Swiss scientists have found that chewing gum often damages the substances used to fill teeth in the mouth, releasing the amalgam, causing the mercury content in blood and urine to exceed the standard, thus causing harm to the brain, central nervous system and kidneys.
5. People with stomach problems should not chew gum too much.
Don't chew gum for more than 15 minutes, especially for people with stomach problems. Because chewing gum for a long time will reflexively secrete a lot of gastric acid. Especially in the fasting state, not only will there be symptoms such as nausea, loss of appetite, acid reflux, etc., but it may also aggravate stomach problems in the long run.
