Hopefully, by the end of this article, you'll know exactly what to look for in the world of natural mouthwash and which one is best for your oral hygiene.

Briefly before we get started, let's take a quick look at how and when to use mouthwash, and why you might want to switch to a natural one.

Types of natural mouthwashes

Many people have questions about how often and when they should rinse with mouthwash. Basically, mouthwash (also called mouth rinse) is a method of cleaning that gives you another chance to get between teeth apart from brushing and flossing.

According to the Oral Health Foundation, there are two types of mouthwash:

It might feel like a long time, but 30 seconds of swishing is the minimum!
  • Treatment mouthwash includes active ingredients meant to kill bacteria and help treat gum disease. Some also contain fluoride to help against cavities and reduce tooth decay by strengthening enamel.
  • Cosmetic mouthwash is basically only meant to freshen your breath but doesn't contain anything that will contribute to better dental health.

One of the main advantages of using a mouth rinse is that the treatment ingredients reach the space between your teeth that brushing and flossing may not. And, they can help with decay or strengthen the enamel in addition to freshening your breath.

Cosmetic mouthwash doesn't really do much, so if you want anything more than fresh breath, make sure you look for active treatment ingredients.

Ask a hygienist!

brushing and flossing. Certain ones can be recommended by your dentist when you have specific issues like tooth sensitivity, gum bleeding, swollen gums or advanced gum disease. 

Although mouthwashes alone cannot treat these conditions, a combination of dental treatment, good at-home oral hygiene regimen with the use of mouthwash can go a long way in restoring dental health. 

Mouthwashes can be chemical-based, contain essential oils, and have natural elements in their composition. Some traditional mouthwashes can contain small concentrations of alcohol which people may be allergic to or dislike the taste. Natural alternatives can be considered in these cases. 

The market is flooded with a lot of products that can help maintain good oral hygiene, but it is imperative to check with your dentist/hygienist which is best for your needs.

What's the best way to use natural mouthwash?

Whether you're using an all-natural mouthwash or a regular mouthwash, the method is the same: swill it around your mouth for at least 30 seconds. You can do this once every few days or more. Some mouthwashes may require you to dilute with water prior to usage and it is based on manufacturer as well as dentist’s recommendations.

Think it's time to change to a natural mouthwash?

The important thing to remember is that you shouldn't use it right after brushing your teeth! Your teeth still benefit from residual toothpaste after brushing, and you don't want to lose that effect.

A great time to use a mouth rinse if possible is after lunch. Most people don't brush or floss in the middle of the day, but a rinse with mouthwash can freshen your breath and give you the health benefits you're looking for.

There are more and more natural and organic ingredients used in mouthwash.

There are several reasons why someone may look for a natural mouthwash. One of the most common reasons for seeking an alternative mouthwash is a fluoride allergy. However, many people avoid fluoride even though they aren't allergic.

Beyond that, natural mouthwash can offer some ingredients that aren't common in standard rinses, such as tea tree oil, aloe vera, clove, or even coconut oil.

Some of the best natural mouthwashes are also 100% organic. Some are vegan, with absolutely no animal testing done during research and development.

Finally, some people like natural mouth rinse because they want to avoid excess waste. Many of them actually choose to make their own homemade mouthwash or rinse their mouths with hydrogen peroxide mouthwash. For now, we're just going to focus on what you can find on the market today.

So without further ado, let's take a look at a few of our favourite natural mouthwashes.

The Natural Dentist Mouthwash reviews

I started to develop periodontitis, and my hygienist requested to see me every four months. After I used this mouth rinse for a few weeks, my hygienist said my gum had improved a lot, and that she only needed to see me every six months.

I really like that it has no alcohol, which I cannot stand. After the rinsing, it leaves my mouth feeling nice and clean. And my gum doesn't bother me anymore.

-Jon Riley, Amazon Review

This review is on The Natural Dentist Healthy Breath Mouthwash. Jon seems to be pleased with the fact that his gum disease has improved after using the mouthwash, and as a bonus loves the fact it is alcohol-free!

This is one of the best mouthwashes I have come across for bleeding gums. Very nice flavour and works very quickly. Does not stain the teeth like some other mouthwashes on the market.

Ecodenta doesn't just make a natural whitening mouthwash. In fact, they have a whole line of popular natural mouthwashes worth checking out, including their kids' mouthwash. It is recommended that children under 6 years old should not be using a mouthwash.

This is for concerned parents who want a natural mouthwash for kids to add to their children's oral hygiene routine. And, to make things a little more exciting for children, Ecodent has a mouth foam rather than a mouthwash.

This mouth foam is vegan, fluoride-free, and has no artificial sweeteners or flavours. It meets all the important criteria for a natural mouthwash. Most importantly, it comes in a kid-friendly minty melon flavour!

Mouth rinse with other special ingredients

Desert Essence Natural Refreshing
Tea-Tree Oil Mouthwash

Now that you've seen our top picks, maybe there's a specific ingredient you're looking for that you haven't seen yet. So it's worth mentioning a couple more mouthwashes with ingredients that aren't always easy to find.

If you want tea tree oil in your mouthwash, look no further than the Desert Essence natural refreshing tea tree oil mouthwash, which contains Pure Australian Eco-Harvest® Tea Tree Oil, Chamomile and Myrrh.

This mouthwash is alcohol-free and sugar-free and contains a lot of botanical extracts. The Chamomile, Myrrh and Aloe provide relief for sore and irritated gums and the Australian Eco-Harvest® Tea Tree Oil and Zinc Citrate help to fight plaque, bacteria and sugar acids.

If you're looking for a spicier flavour try JASON natural mouthwash, which contains tea tree oil and aloe vera, as well as clove and cinnamon to help fight against bad breath. That being said, we would consider this to be more of a cosmetic mouth rinse.

Georganics Organic Whitening Oil
Pulling Mouthwash

Another notable option is the Georganics Organic Whitening Oil Pulling Mouthwash. This one is also SLS and fluoride-free. What sets it apart is that it contains aloe vera and coconut oil.

Finally, Dr Brite offers an alternative to mouthwash in the form of gentle oral sprays. These sprays get rid of bad breath while they soothe and clean with natural ingredients like activated charcoal, organic aloe and organic mint!

Dentists won't usually stress using mouthwash as much as brushing or flossing. Nonetheless, it constitutes an important part of a good oral hygiene routine. There are a lot of options out there, but whatever your preferences there will be a type of mouth rinse to suit your needs.

If you want a natural mouthwash with maximum effectiveness consider one with ingredients that treat and prevent periodontal disease, and not just bad breath.

Though there are lots of appropriate times to use mouthwash, we want to remind you that it's not ideal to rinse your mouth out immediately after brushing. Residual toothpaste will continue to clean and strengthen your teeth for some time after you brush your teeth, and you shouldn't cut that short!

Instead, wait 30 minutes or find another time that fits into your schedule, like right after lunch.


How can I get rid of gingivitis naturally?

The best and most natural way to get rid of gingivitis is frequent tartar removal. You can do this by brushing your teeth twice (and flossing once) every day. Most people's routines often involve lots of plastics and synthetic chemicals, but these can be avoided by using organic toothbrushes and natural toothpaste.

Is fluoride really dangerous?

While some are cautious about fluoride due to allergy concerns, it is generally safe when not ingested in high concentrations. Many cities worldwide add fluoride to drinking water without negative health effects, but excessive fluoride intake can lead to ‘fluorosis,' impacting tooth health.

Can I swallow a natural mouthwash?

You should avoid swallowing any mouthwash, regardless of its ingredients. While certain chemicals, whether natural or synthetic, benefit teeth, ingestion can pose harm. For instance, tea tree oil, commonly found in natural mouthwash, is toxic when swallowed. Prioritize never swallowing mouthwash for your safety.

What's the best way to use natural mouthwash?

Whether opting for an all-natural or regular mouthwash, the technique remains consistent: swish it in your mouth for a minimum of 30 seconds. Repeat every few days or as needed.
