Final answer:
False. Evidence does not support that water fluoridation is unsafe and ineffective for the prevention of dental caries. Community water fluoridation has been identified as the most cost-effective method of delivering fluoride to all, reducing tooth decay by 25% in children and adults.

Fluoride helps to rebuild and strengthen the tooth's surface, or enamel, preventing cavities and even rebuilding the tooth's surface. In addition, studies have shown that toothpastes with xylitol as an ingredient are more effective at preventing dental caries in permanent teeth of children than toothpastes containing fluoride alone.
