Mouthwash Brands

ALDI Dentitex

ALDI Dentitex

Supermarket giant ALDI is a favourite for a range of products from home cleaning to your everyday grocery items, like milk and frozen vegetables. It also stocks all your bathroom essentials, including mouthwash under the brand name Dentitex.

  • In 2018, ALDI Dentitex was an outstanding performer with five-star reviews in all categories including effectiveness, freshness of breath, value for money, taste, packaging and overall customer satisfaction.



Listerine has a large range of mouthwashes. Its line-up targets different needs, including anticavity, alcohol free, antiseptic, cavity protection, enamel care, gum protection, sensitivity and white teeth. There’s also an option for kids (6+) – an anti-cavity mouthwash with a berry flavour. The full range is claimed to kill germs, reduce plaque, provide fresh breath and protect your gums. Expect a number of different flavours from Cool Mint to a ‘Fresh Burst’. There are both 500ml and 1L bottle variations.

  • Listerine achieved four stars for overall satisfaction, as well as effectiveness, taste and packaging. It got five stars on freshness of breath but just three stars on value for money.



Oral-B provides a concise range of mouthwashes. It features its 3D White Luxe Diamond (473ml) mouthwash in a mint taste, stated to target teeth whitening, strengthen tooth enamel and kill bad breath. Oral-B’s Pro-Health Anti-Plaque Mouth Rinse (500ml and 1L) is claimed to help fight plaque and protect from germs, while its Fluoride Rinse (500ml) is said to be alcohol free and also comes in a mint taste.

  • Oral-B was another brand to score four stars on overall satisfaction and two other categories – value for money and packaging. It was five stars for all other variables.



Colgate offers a number of different options. Its mouthwashes include Dry Mouth Relief, Optic White, Gentle Care, plus one designed for kids. There’s also a number of different flavours from peppermint to fresh tea. Its Total Advanced Pro-Shield mouthwash is boasted to provide 12-hour protection against plaque bacteria with an alcohol-free formula. Sizes range from 500ml to 1L, and 250ml for the kids’ variant. Its range also extends to Colgate’s Savacol Mouth & Throat rinse, stated to be an antiseptic mouth and throat rinse to help assist in the treatment of medical-diagnosed gingivitis.

  • Colgate got four stars on overall satisfaction. It also got four stars on effectiveness, freshness of breath, taste and packaging. It was three stars on value for money.



Coles has a very modest line-up when it comes to mouthwash. At the time of writing, it offers just one mouthwash – Coles Mint Fresh, stated to be made in Australia and available in a 500ml bottle.

  • Coles was left with three stars for overall satisfaction and all other categories, including effectiveness, freshness of breath, value for money, taste and packaging.

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:

  • Effectiveness: 27%
  • Freshness of breath: 26%
  • Value for money: 20%
  • Taste: 15%
  • Packaging: 11%

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


The most important driver of satisfaction was effectiveness. Mouthwash brands typically target specific symptoms and offer a range of products to help with the different problems you might have. According to our survey, 48% said they use mouthwash for health reasons (e.g. gum disease/cavities/plaque), 26% think it’s good for them, and 19% use it to get rid of bad breath. With a huge line-up of options, there’s certainly plenty of choice if one brand doesn’t cut it.

Freshness of breath

The second most important factor was freshness of breath. This is typically a benefit that most brands claim to deliver. According to mouthwash manufactures, common ailments such as heartburn or acid reflux can leave you with bad breath, as well as bacteria and mucus build-up. So, finding a mouthwash that helps to reduce bad breath is beneficial.

Value for money

The third key factor was value for money. You can find mouthwash starting from around $2 for a 500ml bottle, rising to more than $10 for a 1L bottle. It was tough for the five brands in our review to win over consumers in this category, with most receiving three stars.


While peppermint and spearmint are common mouthwash flavours, there are also a number of other options available, such as a ‘hint of refreshing tea’. It’s certainly unpleasant when a mouthwash is too strong and leaves your mouth feeling uncomfortable post-gargle, so it’s important to find one that you like enough to use on a daily basis.


Last but not least – packaging. It may not directly affect the end result, but it certainly helps with the overall experience. With 54% of respondents to our survey using mouthwash every single day, 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.

Frequently Asked Questions

Canstar Blue surveyed 3,000 Australian adults across a range of categories to measure and track customer satisfaction, via ISO 26362 accredited research panels managed by Qualtrics. The outcomes reported are the results from customers within the survey group who have purchased and used mouthwash in the last 6 months – in this case, 1,451 people.

Brands must have received at least 30 responses to be included. Results are comparative and it should be noted that brands receiving three stars have still achieved a satisfaction measure of at least six out of 10. Not all brands available in the market have been compared in this survey. The ratings table is first sorted by star ratings and then by mean overall satisfaction. A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criteria.
