When you chew a gum, it gives your facial muscles a workout, tightening them. Chew one gum daily for at least an hour to benefit from the exercise. It will not only help with saggy chin but will also define your cheeks. If you have a gum addiction, you may not be too happy to hear this: Some cosmetic surgeons have found that patients who chew gum excessively develop wrinkles around their mouths. These wrinkles are caused by the repetitive motion of chewing, which causes the skin around the mouth to fold and eventually cause lines.

Chewing gum is one of the easiest ways of improving your jawline definition. The chewing action works the muscles in your neck and jaw, which really tightens up the whole jawline and chin area. And if you're constantly chewing, you're working those muscles all day long. While you can't totally fight aging or genetics, there are some things you can to do to improve the look of your jawline. Exercising the jaw muscles helps build them up and give your jaw a more defined look.

Only chewing gums that are sugar-free can be considered for the ADA Seal. They are sweetened by non-cavity-causing sweeteners such as aspartame, sorbitol or mannitol. Chewing sugar-free gum has been shown to increase the flow of saliva, thereby reducing plaque acid, strengthening the teeth and reducing tooth decay.
