Toothpaste. It is one of the very few products that you use at least two times per day, seven days per week. Because it is such a common product, you would think that people would be more vigilant about what ingredients are lurking in the tube, but there are several harmful ingredients that have gone all but unnoticed. Here are 6 harmful ingredients that you should definitely be avoiding.



For many years, people have thought that fluoride was essential in promoting good dental health. However, the fluoride protection layer on the tooth has been shown to be 1/10000th of the width of a hair, which is easily eliminated through chewing. Our teeth simply don’t need fluoride, especially not at the rate that dentists are pushing it. An excessive intake or build up of fluoride is poisonous.

SLS ( Sodium Lauryl Sulfate)

When processed, this ingredient is often contaminated with 1,4-dioxane, which is a known carcinogen. Studies have also shown a connection between SLS and organ toxicity, reproductive toxicity, and endocrine disruption.

Artificial Flavors / Colors

Many people are sensitive or allergic to ingredients used in artificial flavoring. Not to mention, studies have found many artificial coloring additives to be toxic.


DEA is a hormone disruptor and can cause stunting in fetal brain development. There is limited evidence of it being a carcinogen. This chemical is harmful to fish and other wildlife, so it is certainly harmful to you.


Propylene Glycol

This is part of the paraben family, which has been shown to cause interference with male reproductive functions. Parabens break down in the body to form a chemical that has been linked to estrogenic activity in breast cancer cultures (which is bad news!).


This is an antibacterial agent which is a suspected endocrine disruptor and may contribute to antibiotic resistance in bacteria. It is important to limit your use of antibacterial items as overuse is ultimately harmful.


There are a few fluoride free and natural toothpaste options in supermarkets such as Target and Walmart, but in case your selection is limited, why not make your own tooth paste? These are a few recipes that you can try out. I’m especially interested in the remineralizing toothpaste. I’ve definitely got to try that out!
