How long can you chew gum at most

Chewing gum frequently can increase saliva secretion, thereby better cleaning the mouth and teeth. However, medical experts do not advocate chewing gum as a fashion, especially chewing gum too much or for too long may have adverse effects on health.

First of all, most chewing gums use sucrose as a sweetener. When you chew gum, the sugar will stay in the mouth for a long time. The caries-causing bacteria in the mouth will use the sucrose to produce acidic substances, which will corrode the teeth.

Secondly, people who have had their teeth filled with mercury-containing materials should not chew gum. Studies have found that frequent gum chewing can damage the material used for dental fillings in the mouth. Doctors recommend that you should not chew gum for more than 15 minutes, and people with stomach problems should not chew gum too much.

In addition, if you chew gum for too long, your chewing muscles will always be in a tense state, which may lead to a habit of grinding your teeth at night. In addition, if teenagers chew gum during their physical development period, it may over-exercise the masseter muscles, stimulate the development of muscles and bones at the mandibular angle, and eventually result in a "square face" appearance, which affects the shape of women's faces. Therefore, each time you chew gum, you should limit yourself to less than a quarter of an hour.
