Chewing gum too much and for too long may have adverse effects on health.

First of all, most chewing gum uses sucrose as the sweetener. When chewing gum, the sugar will stay in the mouth for a long time, and the cariogenic bacteria in the mouth will use the sucrose to produce acidic substances, which is harmful to the teeth. Corrosion occurs, causing teeth to decalcify, thereby inducing dental caries.

Secondly, people who have had their teeth filled with mercury-containing materials should not chew gum. Studies have found that chewing gum regularly can damage the materials used in dental fillings in the mouth, causing the amalgam in them to be released, resulting in excessive mercury levels in blood and urine, thereby causing harm to the brain, central nervous system and kidneys.

In addition, chewing gum is not good for children. Because children have poor self-control and keep chewing gum in their mouths all day long, they may swallow it or accidentally enter their trachea, which can be life-threatening. Also, if you chew gum for a long time, the masticatory muscles are always in a state of tension, which may lead to the habit of grinding teeth during sleep, thus affecting the child's sleep quality.

Doctors recommend that you should not chew gum for more than 15 minutes. People with stomach problems should not chew gum too much, because chewing gum for a long time will reflexively secrete a large amount of gastric acid. Especially in a fasting state, not only will symptoms such as nausea, loss of appetite, and acid reflux occur, but it may also lead to diseases such as gastric ulcers and gastritis in the long run.
