Most people use mouthwash in the hope that it will leave their mouth feeling extra fresh and clean. In reality, it leaves your mouth stinging and can make your breath smell worse.

This is because the main ingredient in most mouthwash is alcohol. Alcohol is very abrasive and can dry your mouth out with long term use. Having a dry mouth makes bad breath worse, so alcohol is definitely an ingredient to steer clear of!

Our zero waste mouthwash alternatives use natural ingredients that are less harsh, but just as effective. They’ll leave your mouth feeling clean and smelling great. Moreover, they eliminate the need to use any single-use plastic which would otherwise be thrown out.

Once you’ve swapped your mouthwash, why not try swapping to a more sustainable toothpaste option too?

We cover both homemade options, and products you can buy.

Baking Soda is a common ingredient in homemade mouthwash

The thing we love about homemade recipes is that you know exactly what’s going into the end product and if there are any ingredients you don’t like, you can simply leave them out.

Furthermore, you can tweak amounts and flavorings until you’ve found a unique blend that is perfect for you!

Common ingredients and their benefits

Filtered Water

While not an active ingredient, water is needed to mix all of the ingredients together and create a liquid. Filtered water is best as tap water can get contaminated with harmful bacteria much more quickly.

Baking Soda

The main active ingredient in most natural mouthwash recipes, baking soda neutralizes acid in your mouth protecting your teeth from acid wear.

It’s a mild abrasive so also helps remove plaque. Baking soda is a common ingredient in many homemade recipes, it can also be used to make tooth powders and eco-friendly washing up liquid.

Peppermint Essential Oil

Peppermint oil ensures that your breath is left minty fresh, and makes the mouthwash taste nice.

Tea Tree Essential Oil

This essential oil is well known for having antibacterial properties. You can also add other essential oils such as cinnamon, clove and wintergreen.

Xylitol

A natural sweetener which also has properties that help fight cavities

Salt

Salt will help soothe your mouth, reducing any inflammation and healing sores. It also aids in the remineralization process of your teeth and stimulates saliva production to prevent dryness

Aloe Vera

A readily available ingredient, studies show that Aleo Vera can reduce gingivitis and reduce plaque. It is a non-abrasive ingredient so good for people with sensitive teeth.

Coconut Oil

Known for its antibacterial and antimicrobial properties, coconut oil is common in many homemade mouthwash recipes

You need no more than 2-3 minutes.

Frequently asked questions

Should homemade mouthwash be refrigerated?

Yes, we recommend storing your DIY mouthwash in the fridge, so it lasts longer. If you prefer room temperature mouthwash, you can take a small amount out a few hours before use and leave to warm up.

How long does homemade mouthwash last?

Since this recipe doesn’t have any preservatives in the mouthwash will only last around 7-14 days. Therefore, you should only make small batches and plan to make a new batch every other week.

Try not to drink straight from the container you are keeping the mouthwash in, as this will contaminate the mixture faster.

Is homemade mouthwash safe for children?

Yes, it is safe to give to children. The only thing to be careful of is the use of essential oils, some are not safe for younger children, and no one should swallow them.

If you are worried your child might accidentally swallow the mouthwash, you can remove essential oils from the recipe. Instead, you could infuse the water with fresh herbs or use peppermint extract.
