Too much fluoride can lead to fluorosis, a discoloring of your teeth and breakdown of enamel -- itself a result diametrically opposed to the dental health it supposedly is meant to prevent -- and more serious developmental problems such as lower IQ. Excessive use of fluoride also increases your risk of osteoporosis and can damage your nervous system, not to mention its links to:
- Developmental and reproductive toxicity
- Endocrine disruption
- Organ system toxicity
Others are seeking natural toothpastes because they’re catching on to the importance of limiting your exposure to as many artificial chemicals as possible. And rest assured that fluoride is not the only skeleton hiding in your typical toothpaste’s closet.
A quick reading of the ingredients in one leading brand of toothpaste reveals:
- Triclosan: A preservative and cosmetic biocide that has been linked to endocrine disruption, organ system toxicity, and bioaccumulation
- Sodium lauryl sulfate: A cleansing agent linked to cancer and developmental and reproductive toxicity
- Tetrasodium pyrophosphate: An oral care agent that animal studies have found impact your brain and nervous system at low doses
- Hydrated silica: An anticaking agent that bioaccumulates in people and wildlife
- FD&C Blue 1: An artificial coloring linked to cancer
- Sodium monofluorophosphate: An oral care agent linked to neurotoxicity, developmental and reproductive toxicity, and possibly cancer.
- Sodium lauryl sulfate: Same as above.
Look for a simple natural, non-fluoride toothpaste with only familiar ingredients, and skip all of the bells and whistles like “whitening,” “enamel strengthening,” and “multi-action.” If you’re looking for a safe way to make your teeth whiter, you can try this truly natural formula using strawberries and baking soda.
Many people think their non-fluoride toothpaste is healthy. However, it is much more difficult to find toothpaste that doesn't contain Sodium Laurel Sulfate (originally created as an engine degreaser).
