Are There Harmful Substances in Your Toothpaste?

Many people don’t give too much thought as to what’s in their toothpaste. Aside from the fluoride content, there is very little to interest the average brusher. However, there are certain ingredients found in trace amounts in many common pastes that may have unfortunate implications. In small amounts, they are likely entirely harmless, but with over seven hundred brushings every year, these substances can build up. Some of the ingredients to look out for include the following:

  • Blue Dye No. 2: It has been suggested that this artificial color can be attributed to the development in learning and behavioral issues in children.
  • Hydrated Silica: This substance is an abrasive, which is an important part of a toothpaste. However, this abrasive is particularly strong and can break down your enamel over time.
  • Sodium Lauryl Sulfate: Some people find this substance irritating, and it has been known to cause or irritate canker sores.
  • 30: The Environmental Protection Agency does not yet understand the effects of this substance, and further study is required.
