According to the Idaho Oral Health Alliance, “the fluoride added to public water meets strict safety standards and complies with the Safe Drinking Water Act. But remember, in Idaho, no public water systems (except Mountain Home Air Force Base) add fluoride to reach optimal levels.”

In other words, it’s best to drink fluoridated water, but is it really reaching your home? Is it sufficient to keep your tooth enamel strong and mineralized?

Fortunately, most of us rely on bottled water for drinking, but even this may not be sufficient.

Your dentist in Ponderay, ID, recommends adding a fluoride treatment or dental sealant to your prevention plan. These treatments are especially valuable for children.

How Idaho Water May Affect Your Teeth

Tap water contains fluoride, but the level varies by location. Too little fluoride intake can lead to tooth decay. Excessive fluoride intake can lead to dental fluorosis, resulting in tooth discoloration.

Considerations for tap water in North Idaho include:

  • Fluoride: Is there enough? Is there too much?
  • Hard Water: Hard water, characterized by a high mineral content, can contribute to tartar buildup.
  • Chlorine: In small amounts, Chlorine in drinking water is harmless and guards against contamination.

The primary consideration should always be fluoride content. If your tap water does not contain sufficient fluoride or if you’re unsure, consider bottled water for drinking. You can also look into bottled fluoridated water.

How Your Dentist Can Help

Your dentist in Coeur d'Alene, ID, can examine you or your child’s teeth to help determine whether you’re getting enough fluoride or too much.

To help lower your tooth decay risks, your dentist can also provide the following services:
