Helpful but...: Both xylitol and Fluoride in tooth pastes are helpful in reducing tooth decay but in different ways. Are they "necessary"?, no. They may be helpful. The best way to prevent tooth decay and have healthy gums is to brush and floss properly after meals and snacks and minimize sticky, sugary, starchy foods that cling to your teeth by choosing healthier substitutes.

Fluoride : Fluoride has been shown to reduce decay. There are non Fluoride containing toothpastes that contain remineralizing agents ( mi paste available with and without fluoride, renew) which are available from your dentist. Xylitol does help to reduce the acids that cause decay, however, Fluoride or remineralizing pastes offer additional protection.

Fluoride is best: Fluoride is best for decay, xylitol is great-- 5 carbon, great for ph issues, best to check out your decay rate, you can have a ph saliva test or biofilm test with carifree system, or bana, many tests to see your risk.

Synergistic: They help to reduce tooth decay by different mechanisms. So i like toothpastes with both.

Yes: Fluoride help desensitize enamel also helping reduce cavity.
