Some Shocking News About Toothpaste Ingredients

Certain substances in toothpaste are more harmful than others. For instance, some of them have Propylene Glycol in them. This chemical is also found in antifreeze, paints, enamels and de-icers. Does that sound like an ingredient you want on your teeth?

Fluoride, another common toothpaste ingredient, can cause damage to nervous and endocrine systems if swallowed on a regular basis.

Moreover, the Diethanolamine (DEA) found in some oral hygiene products mixed with the wrong ingredients can cause cancer. Areas in which DEA can cause problems if repeatedly ingested over a period of time, include the stomach, esophagus, liver and bladder.

You might also be surprised to find out about the negative effects of common ingredients such as Spearmint and Peppermint found in everything from regular chewing gum to organic toothpaste products.

Recent research indicates that these substances may decrease testosterone levels in males when ingested on a regular basis. In other words, it can diminish your ability to reproduce as well as causing a whole host of other side effects related to low testosterone.

The good news is that using the previously mentioned natural toothpastes you can avoid these harmful substances. We have chosen what we believe are the best formulas for oral hygiene.


Ultimately, we can't tell you how to take care of your teeth. All we can do is offer our suggestions based on what we have found to be the best organic toothpaste brands. Among our favorite choices, we would say choose the one you think has the most appealing flavor for you.
