What are the advantages and disadvantages of chewing gum? does it releases face fat

Gum: Chewing gum stimulates salivary flow which is protective for teeth. However, unless it is sugar free, chewing gum bathes the teeth in constant sugar, which promotes tooth decay. Sugarless gum is the key for those who chew gum.

Gum can help or not: Gum chewing, as long as it contains xylitol or is sugarless, has the benefit of creating less-likely environment for decay, because it increases saliva (and the xylitol reduces certain bacteria). The negative can be that your joints and muscles sometimes get overtired from all that chewing - it depends on the patient. Just make sure if you chew gum, the only sugar present is xylitol.
