Answer:
Improves Concentration
At work, chewing gum helps us concentrate on the task at hand. Many truck drivers find that chewing gum helps them stay alert at the wheel. Eases Tension
As early as 1939, scientific studies showed how chewing reduces muscular tension and helps people feel more at ease. Because it is so well-recognized for helping stay alert at the same time it eases tension, the U.S. Armed Forces have supplied chewing gum to its soldiers ever since World War I. It is still included in field and combat rations today. Freshens Breath
Chewing gum, especially a mint-flavored gum like Wrigley's Spearmint or Doublemint, moistens and refreshes the mouth and throat and sweetens the breath. Provides a Low-calorie Snack
Chewing gum often satisfies the desire for a between-meals snack, yet each stick averages less than 10 calories. Helps Fight Tooth Decay
After meals, it isn't always convenient to use a toothbrush. Chewing gum stimulates the production of saliva, which helps neutralize acids from foods that may cause tooth decay.

Freshens breath
some kinds can whiten teeth, I think
tastes good and there's a variety of flavors
apparently it can help you concentrate somehow, and maybe keep you calm

Well, I guess it can clean your teeth by keeping you salivating, and gives you fresh breath. I hear that it can also help people concentrate/think, though this isn't true for everyone.
