1, clean your mouth and freshen your breath.
Chewing gum, its mechanical adhesion can help remove food residue on the occlusal surface of teeth. Chewing can promote salivary glands to secrete saliva and help clean the mouth; Adding substances such as mint can also refresh the breath and make people feel refreshed. Therefore, chewing gum is an expedient measure to clean the mouth when there is no condition to brush your teeth.
However, this kind of cleaning can never replace brushing your teeth. Brushing your teeth can remove food residues and dental plaque inside and outside your teeth and thoroughly clean your mouth, which chewing gum can't do.
2. Relieve mental tension and adjust mood.
Chewing helps to relax emotions and relieve tension and anxiety. Many athletes have the habit of chewing gum before or during the competition. Psychological research shows that chewing gum can alleviate low and moderate test anxiety, and the subjects who chew gum during the test show higher alertness and lower anxiety level and stress.
3. Exercise muscles and move joints.
Because cooking is fine now, eating food has less and less exercise on masticatory muscles. Moderate chewing gum can exercise masticatory muscles and move temporomandibular joints, which is beneficial to show facial muscle lines.
Disadvantages of chewing gum frequently:
1, excessive exercise, resulting in face changes.
Everything has gone too far. Chewing gum often will not only lead to excessive fatigue of masticatory muscles, but also lead to excessive muscle development in the long run and change the face shape-the mandibular angle is full and the face tends to be Chinese. In some severe cases, the mandibular muscles on both sides are obviously prominent, which looks like something is in the mouth. Many handsome men and beautiful women who love beauty have to have plastic surgery because of this.
2. Stimulate gastric acid secretion and cause stomach trouble.
Chewing directly stimulates the secretion of digestive juice, not only saliva, but also gastric juice. Gastric acid in gastric juice is a good helper for digestion, but too much gastric acid, or fasting, will do harm to the gastric mucosa itself, causing gastritis and even gastric ulcer. Therefore, try to avoid chewing gum on an empty stomach for a long time; Stomach patients are also not suitable for chewing gum.
