Why you Should Make Your Own Mouthwash

If you have ever read this blog before then you know I’m all about eliminating toxic chemicals from the home. We are constantly being bombarded by enviromental toxins and it is so important to try to reduce our toxic burden however and wherever possible.

Store-bought mouthwash is definitely a place nasty toxins like to hide. A few nasty ingredients to look for are below.

Chlorhexidine gluconate

Methyl salicylate

Ethanol (ethyl alcohol)

Aside from the ingredients listed above, store bought mouthwash also almost always contains synthetic colors and flavors as well. Both of which can be harmful to your health.

You can search for your favorite mouthwash on the EWG website to see whether or not the ingredients it contains are dangerous or not.

There have also been many claims made over the years that mouthwash containing alcohol can cause oral cancer. It’s been an ongoing debate that doesn’t exactly have a clear answer.

Below are a few articles discussing this issue. I encourage you to do your own research and come to your own conclusion.

Like so many other areas in my life, I like to err on the side of caution. That’s why I make my own mouthwash that is alcohol-free.

Before I share the ingredients and recipe I thought it would be helpful to address a few frequently asked questions.

Can You Use Thieves Oil in the Mouth?

I do not recommend using thieves oil in the mouth without diluting it first. Several of the oils in thieves essential oil are considered hot oils which means they can burn the skin if they come into direct contact with it without being diluted first.

And because the mouth is a very sensitive area you need to make sure thieves oil is properly diluted before coming into contact with any area of the skin, especially the mouth.

Since the thieves oil in this homemade thieves mouthwash recipe is diluted, it can be used in the mouth. Just be sure to shake the mouthwash well before each use.

Does Thieves Mouthwash Work?

There are many benefits to thieves mouthwash which you can learn about below. But to answer the question simply, yes, thieves mouthwash works.

I’ve been using it for over a year and I don’t miss my old mouthwash at all. Plus it’s 100% natural and tastes great.

Can You Swallow Thieves Mouthwash?

I would not recommend swallowing the mouthwash. I wouldn’t worry too much about accidentally swallowing a tiny amount while rinsing your mouth. But just like with any other mouthwash, it should not be intentionally swallowed.

Can You Use Thieves Mouthwash While Pregnant?

I am very hesitant to answer this question because I am not a medical professional. I’ve read conflicting information in regards to whether cinnamon, clove, and rosemary, all of which are used in thieves oil, should be used during pregnancy.

So I would definitely talk to your doctor before using thieves mouthwash.

Does Thieves Mouthwash Whiten Teeth?

To be honest, I haven’t noticed a huge difference when it comes to whitening but to be fair, my teeth are already pretty white.

Not to brag though. It’s all thanks to this awesome toothpaste. It tastes pretty gross but it works sooo good. And my teeth have become significantly whiter ever since I started using it.

So unfortunately, I can’t give a yes or no answer to whether or not thieves mouthwash whitens teeth.

If you’re looking for something that whitens you’ll just have to give it a try and let me know if you notice a difference 🙂
