Would You Brush Your Teeth With Sand?

Just a few days ago, I had an experience that I never dreamed would happen…and weirdly enough, I enjoyed it so much, that I would actually recommend it to other people.

IMG_8064We were on Fraser Island, with Pippies Beachhouse Backpackers. Their three day/two night “tag along” tour was jam packed with 4×4 beach driving, swimming and exploring the beautiful, yet diverse landscapes. First stop: Lake McKenzie, the most visited and picturesque spot on Fraser Island. This is no ordinary lake, and my pictures don’t do it any justice.


Lake McKenzie is ‘perched’ above sea level. Fraser Island contains more than half of the world perched lakes, and over forty are found here alone. It contains only rainwater, so it’s not fed by streams and does not flow to the ocean. The sand forms a layer around the lake so the water is unable to drain away, making it so pure, it becomes unsuitable for many species. If you’re lucky, you may find the odd turtle though!

What makes the lake so beautiful is the sand, which is pure, white silica. You should probably know, sand is not my favourite thing in the world because it really sticks to me. It’s rough, crunchy (which you’d know if you’ve ever been unfortunate enough to experience sand in your mouth) and it gets everywhere, even after I’ve left the beach. No one wants to find sand in their ears a few days later… how does it even get there!?

The sand at McKenzie Lake is different. It’s not only beautiful to look at, but incredibly soft. We spent ages scrubbing our faces, arms and legs, fascinated by the smoothness of our skin afterwards. You can even use the silica sand to wash your hair (which we tried)!


Now, if I asked you to brush your teeth with sand, I reckon you’d think I was mad. I’ll admit, I was sceptical at first, and I thought our tour guide was joking when he recommended it, but I did it: I brushed my teeth with sand.

The sand was just as soft as when I used it on my skin, it certainly wasn’t crunchy like I was expecting. Not surprisingly, you can damage to your teeth if you brush with sand for too long. Matt and I were careful to spread a thin layer, like we would with toothpaste, and rinsed thoroughly. The combination of sand and lake water left my teeth felt clean and smooth afterwards. I’ll be honest, I really enjoyed the experience.

I wouldn’t recommend going to your local beach and trying this, but it’s an absolutely must if you’re travelling to Fraser Island.
