What’s in Your Toothpaste?

The job of looking after your health today is quite a challenge. Even I don’t always get it right.

I used to use a popular, major brand of toothpaste. It advertises “12-hour germ-fighting protection.” Until, that is, I discovered triclosan was in it.

You may remember triclosan. It was in the hand sanitizer that even my staff was using at the office until I called them out on it and had them replace it with a natural alternative.

Now, I’m just as concerned as you about having healthy teeth and gums. But there’s no way I want triclosan to be part of the solution. It’s a pesticide.

There’s no benefit to putting an antibacterial in toothpaste. And it may even be harmful. Because it allows bacteria to grow stronger and more resistant to medication. So, the next time you get an infection, your body might not be able to fight it.(1)

As bad as triclosan is in a hand sanitizer, it’s even worse when you put it in toothpaste. Because triclosan is easy to absorb in your mouth. And researchers have identified it in deep tissues within 3 hours.(2) Once it gets there, it disrupts your thyroid gland. It can also make testosterone drop by over 30 percent.(3,4) Even worse, I’ve seen scientific studies that concluded that tricolosan increased cancer risk.(5)

In Europe, triclosan is banned in food. But here in the U.S., the FDA is still sitting on the fence. They recently posted a report they called “Triclosan: What Consumers Should Know.” But rather than making a clear recommendation, they said they were “reviewing all of the available evidence.”(6)

So, in the mean time, what should you do?

I’ll tell you what I do. I just don’t use toothpaste any more.

Instead, I brush my teeth like the native people I’ve been lucky enough to live with in my travels.

What’s that?

I use salt. It’s been around since biblical times and even before. It’s all you need to freshen your breath, whiten your teeth, toughen your gums, cure gingivitis, and protect your enamel.

I think you should give it a try. It’s completely safe. It’s inexpensive. And it’s available in every grocery store.

Here are a few tips on how to brush using salt:

1. Use sea salt if possible. Sea salt is naturally occurring and it isn’t processed. Table salt can have residual chemicals from the bleaching and refining process.

Sea salt has minerals in it like potassium and magnesium. You can also buy sea salt that’s iodized. We’re not getting iodine from our diet any more, and this is an easy way to increase your daily level.

There are many kinds of sea salt: Mediterranean, Himalayan, Pacific, and many more. They all have slightly different tastes. You can choose whichever you like best.

2. You can use table salt if you don’t have access to sea salt. But you don’t want it too fine. You need the abrasive action you get from coarser salt. On the other hand, don’t use salt so coarse it hurts your gums.

3. For extra breath freshening, chew on mint or spearmint. It’s easy to grow, or most grocery stores carry it. Chew on a leaf or two after brushing. Mint also has many health benefits; among them curing headaches and improving digestion.(7)

4. For extra whitening, once a week, mash a strawberry into a pulp and make a paste with the sea salt. Strawberries contain malic acid, which will increase the whitening effect of the sea salt.

    Definitely going to do this! My only concern is my sensitive teeth. I’ve been using a toothpaste for sensitive teeth and it really works. I wonder if there is a natural solution. Dean

    Do you know if that is the case with Dentu-Creme also? I can’t seem to find a complete list of ingredients anywhere.

    When I was a kid in the late sixties, my grandmother told me they brushed with salt and baking soda. I used it for a while but wonder what was the purpose of the baking soda?

  4. says

    I used peroxide as a mouthwash and gargle. It kills bacteria and whitens my teeth. I use toothpaste for brushing and prefer Tom’s of Maine. It’s all natural. I don’t use the kind with flouride in it.

    Thank you for this, the specifics are good. We need such details to relay to friends. The information with regard to testosterone will galvanize my male friends, who are inclined to be less vigilant than women, and who seem to believe they are bullet-proof.
