The Benefits of Using Hydrogen Peroxide Mouthwash

(And How to Make Your Own at Home!)

You’ve probably heard of using hydrogen peroxide 3% to clean cuts and scrapes, but did you know that this household disinfectant can also be used to make a non-toxic, effective DIY mouthwash?

Thanks to its antimicrobial and cleansing properties, using a hydrogen peroxide-based mouthwash can improve your oral hygiene and brighten your smile without the use of alcohol, fluoride, glycerin, sulphates, or other harmful chemicals. Not to mention, it’s a breeze to make, cost-effective, and environmentally friendly.

You might be thinking, “How do I make this miracle mouthwash?” We’ll get to that—we promise—but first, let’s cover some of the reasons that hydrogen peroxide mouthwash deserves a permanent spot on your counter.

How to get rid of dust mites?

It whitens teeth

Have you noticed that your coffee-a-day habit has made your teeth dull and discoloured? Hydrogen peroxide 3% will take care of that! In the dentistry world, hydrogen peroxide is a well-known tool for whitening teeth. In fact, hydrogen peroxide is the main active ingredient in many over-the-counter and professional teeth-whitening products. 

By gargling with hydrogen peroxide twice a day, you’ll be on your way to sparkling pearly whites in no time.

It eliminates bad breath

You’ve probably tried using expensive, alcohol-based mouthwashes from the drugstore to stifle the embarrassing odour of bad breath, but didn’t get great results.

Are we right?

We want to encourage you not to waste any more time or money on pricey products that don’t deliver the results you’re seeking. There is an easy home solution that is equal parts effective and safe for your body. Thanks to its antimicrobial properties, hydrogen peroxide 3% treats bad breath at the source by killing off bad anaerobic bacteria.

It cleans your whole mouth

As if freshening your breath and whitening your teeth wasn’t enough, hydrogen peroxide 3% effectively cleans your whole mouth. Chemically, hydrogen peroxide is simply water with an extra molecule of oxygen. It works as an oral cleanser by releasing oxygen when swished around in your mouth. The release of oxygen causes foaming, which helps to clear mucus, remove plaque, and clean every crevice of your mouth.

Eliminates morning mouth

We’ve all been there—you wake up and your breath smells less than ideal and your mouth is dry from the lack of saliva overnight. In order to fight what is commonly referred to as “morning mouth,” make peroxide mouthwash the last thing in your mouth before bed and the first thing in your mouth when you wake up. This will work to kill off bad breath-causing bacteria and add moisture to your mucus membranes so that you can wake up and start your day with a fresher, cleaner, more-lubricated mouth.
