What is the minimum recommended daily intake of xylitol for caries prevention?

The recommended daily intake of xylitol for caries prevention is based on numerous studies highlighting its effectiveness in inhibiting the growth of cavity-causing bacteria, particularly Streptococcus mutans. A daily intake of 5 grams is supported by research that indicates this amount is optimal for achieving a noticeable reduction in dental caries risk.

Ideally, consuming xylitol in smaller, divided doses throughout the day maximizes its benefits. This approach allows for sustained antibacterial effects in the oral cavity, as xylitol affects the metabolic pathways of bacteria, reducing their ability to produce acids that contribute to tooth decay.

The emphasis on quantity and division is critical; lower doses taken multiple times are more effective in maintaining an environment conducive to oral health compared to larger doses administered all at once. Therefore, 5 grams per day, ideally spread over several instances, is regarded as the most beneficial strategy for utilizing xylitol as a preventative agent against tooth decay.
