Key ingredients 12
xylitolVery Good
Xylitol is a natural sweetener that helps reduce cavity-causing bacteria in the mouth. It is effective in promoting oral health by inhibiting the growth of harmful bacteria. Its use in toothpaste is highly beneficial for preventing tooth decay.
Risks

Risks

Benefits
