Minty Sweet Homemade Mouthwash (Easy, cheap + non-toxic)

Minty Sweet Homemade MouthwashBefore we even talk about mouthwash, I gotta tell you that bad breath can often disappear when you start eating real, clean food. Forget the constant gum-chewing and mint popping. Once I changed my diet, I no longer had that icky feeling in my mouth 24/7.

Still, there are days when it feels good to freshen up. Not to mention, mouthwash can help overall dental health.

My 4 year old son got interested in mouthwash when he watched my husband using it. That bright green stuff was intriguing and soon he was rinsing his mouth next to Daddy.

Having children will catapult anyone into obsessive label reading.

As soon as I saw that bright green stuff in my kid’s mouth, I took a hard look at the label.

Personal care products are even more confusing than food labels! Seriously. I know you don’t “eat” mouthwash, but kids especially may swallow it. And it’s in your mouth. That means it’s getting absorbed into your body. So let’s look at a few of the ingredients:

actYellow 5 and Green 3 – As with other food dyes, these are linked to cancer, ADHD and allergies. source

Potassium Sorbate – Linked to allergies/immunotoxicity, non-reproductive organ system toxicity. source

Propylene Glycol – Linked to allergies/immunotoxicity, non-reproductive organ system toxicity. source

Methyl Salicylate – Linked to developmental/reproductive toxicity. source

Enough said. The mouthwash had to go. See, these things are considered safe in small amounts. That’s why ACT is allowed on the shelf.

But combine ALL the personal care products you use on a daily basis, plus environmental pollutants, plus junk in our food and water supply…

It adds up. You’re the only one who can take responsibility for your overall consumption of toxic substances. (And your kids’.)

I went on a mission for a replacement. Whole Foods had a couple much more natural alternatives. However, they cost a small fortune for some very basic ingredients.

You can make your own for just pennies.

Prep time
Total time
This recipe purposely uses a very low concentration of hydrogen peroxide. In high concentrations and with daily use, hydrogen peroxide may be harmful to your teeth. Also, there is conflicting information about using stevia for dental care. Hey, I'm no dentist. Several bottled natural mouthwashes use it. You can leave it out entirely.
  • 12 oz. purified water
  • 2 Tbl. 3% hydrogen peroxide solution (the kind you probably already have)
  • 2-3 drops peppermint essential oil
  • Optional: Small pinch of pure stevia
  1. Combine all ingredients and shake to combine.
  2. To use: Rinse mouth with mouthwash after brushing, then rinse with plain water.
