Listerine is a fresh new winner in mouthwash ratings

Brushing, flossing and mouth-washing – it’s all part of a typical morning or night-time routine to help your mouth feel and smell fresh. Mouthwash brands typically have you covered on the standard set of benefits, including reducing bacteria in your mouth and bad breath, while some products are claimed to be an all-purpose mouthwash to help strengthen tooth enamel and improve gum health. With so many options on offer, where do you start? This is where Canstar Blue steps in!

We’ve surveyed more than 1,200 Australian consumers for their feedback on the mouthwash they bought and used in the last six months. Respondents rated brands on their effectiveness, freshness of breath, taste, packaging, value for money and overall satisfaction. Those that received the minimum required survey sample size of 30 responses are compared in our latest report.

There’s also an option for kids (6+) – an anti-cavity ‘smart rinse’ mouthwash with a berry flavour. The full range is said to kill germs, reduce plaque, provide fresh breath and protect gums.

Oral-B’s Pro-Health Anti-Plaque Mouth Rinse (500ml and 1L) is similarly claimed to help fight plaque and protect from germs, while its Clinical Mouth Rinse (500ml) is listed as alcohol-free and also comes in a mint taste.

  • Oral-B scored a solid four-star review across the board, including for taste, effectiveness, fresher breath, packaging, value for money and overall satisfaction.

ALDI Dentitex

This includes Coles Mint Fresh Mouthwash, Coles Pro Teeth Defence Mouthwash and the Coles Pro Total Care Mouth Wash. All products come in a 500ml bottle, with the Coles Mint Fresh Mouthwash being the cheapest option. Similar to Coles’ other alternatives, this is said to prevent plaque and gingivitis as well as fight germs that cause bad breath.

What to consider when buying mouthwash

When it comes to mouthwash, there are a few things to consider. Our research revealed the following drivers of customer satisfaction listed in order of importance:

  • Freshness of breath: 29%
  • Effectiveness: 20%
  • Taste: 19%
  • Value for money: 19%
  • Packaging: 13%

Before we unpack each factor, here’s what else our survey found:

Freshness of breath

What is the most effective mouthwash

No one likes the feeling of morning breath, let alone the smell. So, it’s no surprise that fresher breath ranked as the most important factor of customer satisfaction. After all, over a third of respondents (35%) said they use mouthwash to get rid of bad breath. One in five (22%) additionally prefer an alcohol-free mouthwash, proving a fresh breath is also about how your mouth feels afterward.


Mouthwash brands typically target specific symptoms and offer a range of products to help with the different problems you might have. Our survey showed approximately 48% of Australians use mouthwash for health reasons (i.e. gum disease/cavities/plaque), with almost a fifth (17%) taking a swig as recommended by a dental professional. A small amount even said they sometimes use mouthwash instead of brushing their teeth (12%).


Our survey found that two in five Aussies (39%) use mouthwash every day, so you’ll want to find an option that doesn’t make you gag each time you gargle. Brands offer various flavours and combinations of mouthwash to suit all tastes and preferences, so take your time next time you’re shopping for a new product. While mint and ‘cool’ flavours are often a popular choice for long-lasting freshness, they’re not always for everyone. Those looking for something that doesn’t tingle the tongue might want to opt for more subtle berry and tropical flavours.

Value for money

Best value for money mouthwash

The next key factor in customer satisfaction is value for money. You can find mouthwash starting from around $2 for a 500ml bottle, rising to more than $10 for a 1L bottle. Although it goes without saying that you’ll pay more for the big-name brands, but is it really worth it? Our ratings suggest maybe not, with only 9% of survey respondents buying the cheapest brand of mouthwash.


Last but not least – packaging. It may not directly affect the end result, but it certainly helps with the overall experience. A lot of people use mouthwash every single day, so you’d hope you can find one that’s easy to open and use, and in turn, won’t end up just sitting in your bathroom collecting dust.

Which mouthwash should I buy?

There you have it – Listerine was rated the number one brand of mouthwash, receiving a five-star review for overall satisfaction. Colgate also proved to be a strong choice for taste and effectiveness, while ALDI Dentitex rated best for value for money.

The brand of mouthwash you place in your shopping basket will ultimately depend on your budget and dental needs. You may need to give a few different brands a try before you settle on one that suits you and your taste buds. There are plenty of options out there, so shop around and try something new. You might just find a mouthwash you like, at a cheaper price!
