Learn how to make your own organic mouthwash at home and say goodbye to unnecessary chemicals and costs.

If you've never made your own mouthwash, you probably have a couple of questions about how to go about doing so.

That's why in this article, we'll answer the following questions:    

  • What is the best natural mouthwash?         
  • How can you make your own mouthwash?         
  • Is using hydrogen peroxide as a mouthwash safe?         
  • What can you use instead of mouthwash?

Let's get started!

Why some dentists recommend using mouthwash

There aren't any official guidelines set out by the dental community when it comes to using mouthwash. But you can have a look at what one dentist says about whether or not you should use mouthwash in the video below.

As you can see, there are no set rules when it comes to mouthwash, and if you use it, the kind you use will depend on your particular mouth. Many dentists believe that mouthwash is beneficial to your oral health, but others believe that using mouthwash after meals is overrated. It's possible that both sides are correct—that mouthwash is beneficial to your oral health, but that its effects are also a bit overrated.

The American Dental Association points out that it “may be a helpful addition” to brushing and flossing in your oral hygiene routine. The reasons? Mouthwashes can reach areas that are difficult to reach with a toothbrush, and help reduce or control plaque, gingivitis, bad breath, and tooth decay.

That being said, dentists also advise against using over-the-counter, cosmetic, and therapeutic mouthwashes more than the prescribed limit. Readymade mouthwash can sometimes be harmful to your teeth as it generally contains alcohol and other harmful chemicals. If your mouth is particularly sensitive to alcohol, such a mouthwash can cause dry mouth and other oral health issues.

So, for certain people, mouthwash can be a source of the problems it was meant to tackle in the first place. In this case, we recommend making your own natural mouthwash recipe at home. Yes, it's possible! Jump to the next section to read some easy DIY recipes for mouthwashes that you can easily make at home.

How to make your own homemade mouthwash

The beauty of making your own mouthwash is that you control the ingredients that go into it. You can go for all-natural ingredients or can also add some helpful chemicals like hydrogen peroxide if you’re not allergic in any way. The best part is that it's much cheaper as compared to commercial products.

Before we get into recipes, let's talk about some common ingredients used in DIY mouthwash and the functions that they have.

Essential oil in mouthwash

Essential oil mouthwash is a great alternative to store-bought products

There are all sorts of essential oils that you can include in your mouthwash. These oils are said to have antiseptic and antimicrobial properties which help control bacteria and fungus in the mouth. Thanks to its classic flavor, peppermint is the most popular essential oil in mouthwash, providing that fresh menthol feeling after you rinse.

Others such as clove oil, tea tree oil, oregano oil, and coconut oil are perfectly acceptable substitutes in your mouthwash if you prefer a different flavor profile. Some oils, like witch hazel, are said to give your mouthwash other effects like reducing inflammation or bleeding. You should know that some of these have limited scientific support, but have been used traditionally for years.

Even though they have similar properties, essential oils are not exactly the same and many mouthwash recipes will combine several types to maximize the benefits you receive. In fact, there is already an essential oil blend called thieves oil which is frequently used in recipes on its own or combined with others.

Spices and plant products

Sometimes instead of using oils, people will use spices or other types of plant extracts in their mouthwash. Two very common examples are aloe vera water and xylitol, used to soothe pain and reduce plaque buildup. Xylitol also acts as a low-calorie sweetener. Spices like clove, cinnamon and turmeric are used in mouthwash not just for their flavor, but also for various health benefits.

Turmeric has been used for centuries in Ayurvedic medicine as an anti-inflammatory and antioxidant, and reduces the risk of heart disease. Clove is a popular ingredient in mouthwash for its remineralizing properties. Cinnamon and star anise are also used for benefits including (but not limited to) reducing cholesterol and blood sugar and alleviating cramps and nausea.

Finally, apple cider vinegar and blue-green algae are both known to be effective pH neutralizers in mouthwash, which help keep bacteria and yeast at healthy levels. This is important for treatment and prevention of oral thrush.

Abrasives, whiteners and more

Oils and extracts from plants are all well and good, but there are certain benefits from mouthwash which they will not provide. In some cases, essential oils can help, but won't be as effective as another type of ingredient. Here's a list of common active ingredients in DIY mouthwash and their effects:

  • L-Arginine has been shown to remineralize tooth enamel and fight decay
  • Calcium carbonate abrasive helps loosen food particles and provides some remineralization
  • Activated charcoal acts as a whitening agent and an abrasive for removing plaque and tartar
  • Salt is an age-old antimicrobial ingredient and helps regulate pH
  • Hydrogen peroxide is antiseptic, and can also be found in many whitening products
  • Baking soda in mouthwash loosens mucus and debris, and can also help remove extrinsic staining (surface stains)
  • Colloidal silver is said to have purifying effects in mouthwash, reducing inflammation and fighting bacteria.

So now you know what to use in your homemade mouthwash, though obviously you won't be using all of these ingredients at once. Exactly which ones and the quantities of each will depend on the effects you want from your mouthwash. So let's look at some of the best home recipes for mouthwash, which you can use as a template to later adapt as necessary, depending on your desired effects:

Hydrogen peroxide antiseptic mouthwash recipe

activated charcoal mouthwash
Hydrogen peroxide is a common mouthwash base



  1. Combine all ingredients in a bowl
  2. Mix well, until salt is dissolved
  3. Use about a teaspoon per rinse

This really simple hydrogen peroxide mouth rinse to reduce irritation. Though you can include some essential oils as well, they may react with the peroxide, reducing the effectiveness of both ingredients. Do not use this mouthwash if you have recently had mouth surgery; opt instead for a salt water mouth rinse.

Soothing aloe vera mouthwash (with optional charcoal)

  1. Combine water, aloe, and baking soda in a glass bottle.
  2. Add peppermint and coconut oils.
  3. Close and shake vigorously to mix.
  4. Use 1-2 tsp per rinse.

The aloe and coconut are ideal for alleviating mouth pain and helping treat canker sores. If you want a whitening effect, add a teaspoon of activated charcoal powder together with the essential oils. The mouthwash will also leave you with a soothing herbal sensation after rinsing, thanks to the peppermint oil.

DIY remineralizing mouthwash

  1. Soak anise stars for a few hours in hot water.
  2. Combine L-Arginine and calcium carbonate in a different bowl with water.
  3. Add algae and soaked anise stars to the bowl with other ingredients. Mix well and grind in a blender.
  4. Use about 1 teaspoon for each rinse.

The resulting solution will help you effectively treat cavities through a natural process. It will normalize the pH level of the mouth while creating a balance of healthy saliva and good bacteria.

All-purpose natural turmeric mouth wash

Turmeric has been used in Ayurvedic medicine for generations



  1. Soak cloves in water overnight.   
  2. Add Calcium carbonate, L-arginine, baking soda and turmeric to 1 cup of fresh water.    
  3. Now add soaked cloves and peppermint essential oil. Grind and whisk the solution.
  4. Use 1 teaspoon for each rinse.

Turmeric can help prevent inflammation in your mouth. This homemade mouthwash recipe serves many purposes including the prevention of periodontal diseases and tooth decay, and removal of teeth stains. If you want to include other spices like cinnamon or star anise, simply soak a small amount with the cloves and continue as instructed.

Ask a dentist: Why turmeric mouthwash?

Though chlorhexidine is an effective mouthwash, sometimes it may result in allergic reactions. Curcumin is a polyphenol present in turmeric that acts as a natural alternative to chlorhexidine.

Turmeric mouthwash has an acceptable taste and is also biocompatible. Some scientific studies have observed that turmeric mouthwash shows anti-plaque properties comparable to chlorhexidine mouthwash. Also, turmeric mouthwash is free from the side effects of bitter taste and staining of teeth, which occur with chlorhexidine mouthwash.

Based on this, we can say turmeric mouthwashes have comparable anti-plaque, anti-inflammatory, and anti-microbial properties. Turmeric mouthwash is biocompatible and can be well accepted by people without any side effects.

Can mouthwash be harmful? What can you use instead of mouthwash?

Commercial mouthwashes often contain harsh chemicals. In theory, if you use your mouthwash according to the instructions, and never swallow it, you should be OK. If you want to be especially safe, you can make sure only to use mouthwashes with the ADA seal of acceptance.

Additionally, a mouthwash with alcohol or hydrogen peroxide may have harmful effects on the mouth of one person, but not on the mouth of another. The biggest problem, though, is when mouthwashes claim results that they can't deliver, something which the FDA is trying to crack down on.

If you want to avoid typical mouthwashes, there are also a couple techniques (some of which people have used for centuries) you can use as part of your oral hygiene routine:

  • Salt mouthwash – Mix a few teaspoons of salt in lukewarm water and gently rinse your mouth after meals. This can be particularly helpful with cold sores.
  • Oil pulling – This is a natural healing technique that involves rinsing your mouth with a tablespoon of coconut oil, olive oil, sesame oil, and rinsing with fresh water afterward. This essential oil mouthwash recipe can be included in the daily oral routine.
  • Vinegar rinse – By diluting apple cider vinegar in water you can make a simple mouth rinse to regulate your mouth's pH, and fight against bad breath.

Mouthwashes can be beneficial when it comes to maintaining good oral hygiene and a homemade mouthwash is a viable alternative to over-the-counter natural ones. Easy to make with generic natural ingredients, such a solution could be good for your oral hygiene issues like bad breath.

So, if you have a knack for DIY solutions, these are ideal for you. You can also replace them with a simple essential oil mouth rinsing routine. That said, you need to be aware that such homemade solutions cannot substitute brushing and flossing. These are only effective when included in oral routines that involve regular brushing and flossing at least twice a day.


What is the best natural mouthwash for gum disease?

While there are several types of natural mouthwashes that you can make at home, it's hard to say which is the best. The whole idea lies in the fact that you select ingredients that are specific to your oral issues. So, creating the best solution will depend on what ingredients suit you better, and that depends on your dental history and personal oral hygiene needs.

Is homemade mouthwash only good for bad breath?

Homemade natural mouthwash can eliminate bad breath, but if you use the right ingredients it can help fight against gingivitis, and even strengthen your tooth enamel. The most important thing to know when making DIY natural mouthwash is what ingredients will give you the desired effect.
