I’ve read that rinsing your mouth twice a day with mouthwash is a tolerable short term replacement for flossing.
The sweetener I use by choice is called Xylitol. It has the useful side effect of killing off one of the two kinds of bacteria that cause tooth decay and gum disease.
You can find it as gum or in a granular form that looks and tastes exactly like sugar. It is a substance in a class called ‘sugar alcohols’ that is found in nature (birch sap, corn stalks), not a lab made frankensweetener. It’s the only stuff I’ve found that doesn’t leave a weird aftertaste.
Up to 10g a day are effective against tooth decay, and up to 20g a day is being studied in helping stop bone loss in osteoporosis cases.
The only warning is that your body treats it like soluble fiber and it needs to be introduced into your body gradually over a week or so to prevent soluble fiber’s predictable side effects.
I’m used to it so I can go off it for a week or two then start again with no side effects. My teeth always get scummy feeling faster and my morning breath comes back.
