How much xylitol is in trident gum?

When you call Trident, they will tell you that the amount of xylitol in their Trident and Stride gums is proprietary and they will not disclose the amount. According to Epic Dental, it contains 0.17 gm. In any case, I think it is safe to assume that it is significantly less than 1 gm and therefore not high enough to prevent decay. If you want to prevent decay, studies suggest chewing 1-2 grams, 4-6 times every day. I don't believe there are any over-the-counter gums you can buy in stores which have high enough xylitol levels. You can buy xylitol gums over the internet which have 1 gm per stick.
