Swish away bacteria and bad breath! These crystals easily dissolve in water, creating a refreshing zero waste mouthwash that won't burn or leave your mouth dry. The perfect compliment to the rest of your sustainable oral care routine.


Our mouthwash crystals got an update! Each 2oz jar is now filled to the very top, meaning more mouthwash per jar. Each refill jar contains 60g of mouthwash crystals, which makes about 80 ounces of mouthwash! That's about a 4-6 month supply with daily use.


Peppermint Oil, Vitamin E, Sea Salt, Stevia Leaf Extract, Grapefruit Seed Extract, Aloe Vera, Baking Soda, Menthol, Erythritol and Polysorbate 20 (derived from Coconut Oil)

To Use

Mix about 12 spoonfuls of crystals into an 8oz bottle or jar of cold water. Shake well until crystals have dissolved.

For extra sustainability, we recommend using a bottle or mason jar you already have on hand. But if you don't have a bottle or jar to use, add one of our 8oz glass bottles to your refill order.

Packaging + End of Life

These refills come in glass jars with metal lids, packaged in a cardboard box with a bamboo scoop. The cardboard box can be recycled, and when you've run out of crystals, the jar can be reused or recycled. The bamboo scoop can be composted.

We ship ugly boxes

Our commitment to sustainability doesn't end when you press that checkout button.

We pack all of our orders in reused boxes and envelopes, with reused paper packaging, post-consumer recycled paper labels, and even paper tape.

You may not get an IG-worthy unboxing, but you will get the most sustainable packaging we can possibly find.

Oh and did we mention our shipping is always carbon negative?

Let's go to the real winner in my eyes. Honestly, I could have purchased this exact product many other places, but the packaging A Drop in the Ocean uses to ship will have me coming back time and time gain.

My first purchase from them was some floss a while ago and it arrived in a reused tea box with a hand written note that was written on scrap paper. I was blown away.

I had never seen a company who claimed to be sustainable ACTUALLY prove to be sustainable through and through. The fact that every piece of the packaging was reused and minimal will have me come back over and over again. If I can purchase it here, I will purchase it here.

So refreshing

I've been using this product for a while, and it's the best mouthwash I've ever used. It's light and refreshing and not overpowering. Highly recommend.
