A 29-year-old member asked:

Do artificial sweeteners promote tooth decay like sugar?

No: Artificial sweetners that contain nothing that bacteria can use for "food" do not cause tooth decay . The label would say "non nutrative" sweetner.
Dr. Ronald Smith
Dentistry 40 years experience
No: Most artificial or "sugar free" sweeteners are not metabolized by the bacteria that cause tooth decay. Not all natural "sugars" are bad either. Xylitol is a natural sweetener that has been shown in some studies to lower decay risk.
Dr. Thomas Stelmach

NO: Artificial sweeteners don't have anything in them to support bacterial metabolism. Bacteria that cause decay love sugar and so they metabolize it and produce acids that decay your teeth.
