1, easy to cause abdominal pain and diarrhea

Patrick Takahashi, Ph.D., Department of Gastroenterology, Vincent Medical Center, Los Angeles, California, USA, said that chewing gum can easily lead to a large amount of air swallowing into the stomach, inducing abdominal pain and flatulence, and artificial sweeteners such as sorbitol in chewing gum can also cause diarrhea in some people, which in turn leads to irritable bowel syndrome. Experts suggest that people with poor stomach and intestines had better not eat chewing gum.

2. Change your face.

Chewing gum can refresh breath and relieve stress. However, chewing gum for a long time, the masticatory muscles are always in a state of tension, which may form the habit of grinding teeth at night. In addition, teenagers chewing gum during their physical development may make the masseter muscle overtraining, stimulate the development of mandibular angle muscles and bones, and finally present a "square Chinese face" in appearance, affecting the facial shape. It is best to control chewing gum within a quarter of an hour at a time.

Chewing gum Note:

1, 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. Sticking to chewing gum with xylitol content above 50% of sugar can reduce the incidence of dental caries by 85%.

2. 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.
