Gum: Is it good or bad for you?

White Tooth Dental Takeaways:
Xylitol is not only a natural sweetener but also an anti-cavity agent. For anyone suffering from dry mouth or is prone to cavities chewing a sugarless gum with Xylitol can be a benefit to helping stimulate saliva and reduce cavity risk. It is also important it’s not a citrus flavour- the acid can be detrimental.
For patients with pre-existing TMJD- whether that’s clicking jaw joints or sore jaw muscles from clenching or grinding, I would avoid chewing gum entirely as it will aggravate those conditions.
