(HealthDay News) -- Not every community in the United States adds fluoride to drinking water.
Nonetheless, the American Dental Association supports the practice, saying fluoridated water:
- Helps prevent tooth decay.
- Protects all ages against cavities.
- Is safe and effective.
- Saves money. The average lifetime cost per person to fluoridate a community's supply of drinking water is less than the cost of one filling.
- Is natural. Fluoride is found naturally in groundwater.
