Right Amount of Toothpaste

Doctor Robert recommends:

Before your children is good at rinsing and spitting out the toothpaste, parents should use just a thin smear amount of toothpaste when brushing their children. Even if you are only using a fluoride-free toothpaste for your infant, you should still only use a smear amount. This is to prevent the infant getting accustomed to much sods and flavor, preparing for an easier transition to a fluoridated toothpaste.

Once you child can reliably rinse and spit out completely, a pea-size amount of toothpaste should be used.

Fluoride level in Corona's Water

Every year, the City of Corona’s Department of Water and Power publishes a Consumer Confidence Report detailing the quality of our drinking water.

The purpose of this blog is to highlight information published in this report regarding the fluoride level in Corona’s water.

Corona’s drinking water came from many sources. In the year 2009, 56% of our drinking water came from groundwater wells, 34% came from Colorado River by way of Lake Mathews, and 10% came from State Project by way of California Aqueduct. The water these sources is treated and blended before it is delivered to our tap.

Unfortunately, our Corona’s Water is not optimally fluoridated to prevent dental caries. No additional fluoride is added to our water source to achieve the recommended fluoride level of 0.7-1.2 parts per million (ppm).

The average fluoride level in Corona’s Water is as follows: 0.4 ppm in groundwater, 0.3 ppm in Colorado River water, and 0.7 ppm in State Project water. Calculated with the percentage information above, the average fluoride level in our water is approximately 0.4 ppm.
