What’s wrong with Triclosan in toothpaste?

Mark Burhenne DDS gives us the low-down on whether you should be concerned about Triclosan in your toothpaste.

Colgate Total is a best-selling toothpaste with the active ingredient Triclosan, a pesticide that is added to reduce the risk of gingivitis and kill oral bacteria.

While it’s been shown to reduce cavities, the problem with triclosan is that it’s still a major health risk to take, and with very little upside.

The Triclosan debate has been around for years. It was first brought up in 1974 when the FDA declared that they would look more deeply into the long-term effects of Triclosan use in humans. This was never done and the FDA has yet to finalize their findings. It has recently come to light that the 1997 research used by the FDA in approving Triclosan use in Colgate toothpaste was not independently conducted but was funded by Colgate.

The FDA is now reviewing its initial 1997 ruling, and has now stated that it will make a final ruling on Triclosan in 2016. Manufacturers are removing triclosan from soaps and other personal care products. Canada, Japan, the European Union and Minnesota have banned or are in the process banning Triclosan from personal care products.

So What’s Wrong With Triclosan?

The problem with triclosan is that it indiscriminately kills bacteria in the mouth; this means that it gets rid of both good and bad oral bacteria. However, for proper oral health, the good bacteria are very important. When triclosan kills off these good bacteria, you get bad breath, dry mouth, and a decrease in your body’s ability to build resistance to infections and disease.

Quick Facts You Should Know About Triclosan

Triclosan and Hormone Disruption

While there is presently no research on the long-term effects of triclosan on humans, in animals there are numerous studies that demonstrate that triclosan is a powerful disruptor of the endocrine system.

These studies reveal that animals, when exposed to levels of triclosan similar to the levels of exposure humans receive through consumer products experience

My Recommendation:

Triclosan in toothpaste is a health risk I’m not willing to take and I recommend you don’t take the risk either. There is currently no research indicating what the long-term effects of triclosan use in humans is, but there are no overwhelming health benefits either.

You don’t need triclosan in your toothpaste and using it puts you at risk. My advice is to play it safe and avoid triclosan in toothpaste and other consumer products altogether.

If you are concerned about cavities and gingivitis, proper brushing and flossing technique will keep you in good, long-term oral health.
