Fluoridation

City Ceased Fluoridation in November 2015


The City of San Marcos ceased adding fluoride to its water supply in November 2015 with voter approval of Proposition 1.

San Marcos has naturally occurring fluoride in the groundwater supply, but levels are below the minimum optimized level recommended by the U.S. Department of Health and Human Services of 0.7 parts per million.

Dental Health Tips


Some important ways to ensure dental health include the following.

Use Toothpaste & Mouthrinse With Fluoride


Toothpaste with fluoride has been responsible for a significant drop in cavities since 1960. Look for one with the ADA Seal of Acceptance to make sure it contains fluoride.

Brushing


Brush twice a day (morning and night) or as directed by your dentist and physician.

For children younger than 3 years, start brushing their teeth as soon as they start to appear in the mouth by using fluoride toothpaste in an amount no more than a smear or the size of a grain of rice.

For children 3 to 6 years old, use no more than a pea-sized amount of fluoride toothpaste.

Always supervise your child's brushing to make sure they use the right amount and try to get your child to spit out most of the toothpaste.

Mouthwash with fluoride can help make your teeth more resistant to decay, but children six years or younger should not use it unless it's been recommended by a dentist. Many children younger than 6 are more likely to swallow it than spit it out because their swallowing reflexes aren't fully developed.

Visit Your Dentist for a Professional Application


If you have a good chance of getting cavities, your dentist can apply fluoride directly to your teeth during your dental visit with a gel, foam or rinse.
