Mouthwash Brands

ALDI Dentitex

Supermarket giant ALDI is a favourite for a range of products from home cleaning to your everyday grocery items such as butter and frozen meals. It also stocks all your bathroom essentials, including mouthwash, under the brand name Dentitex. It offers two variants within its line-up – Ultra Fresh or Tartar Control – both available in 1L bottles.

  • ALDI Dentitex was an outstanding performer, with five-star reviews in most categories including taste, packaging, value for money, and overall customer satisfaction. It was also rated four stars for freshness of breath and effectiveness.

Oral B

Oral B provides a concise range of mouthwashes. This includes 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 Clinical Mouth Rinse (500ml) is said to be alcohol free and also comes in a mint taste.

  • Oral B received four stars for overall satisfaction and taste, with five stars in all other categories except value for money, where it was rated three stars.


Listerine has a large range of mouthwashes, with its line-up targeting various 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 said to kill germs, reduce plaque, provide fresh breath and protect gums. Expect a number of different flavours from ‘Cool Mint’ to ‘Fresh Burst’. There are both 500ml and 1L bottle variations available across the range.

  • Listerine achieved four stars for overall satisfaction, as well as effectiveness. It was rated five stars on freshness of breath, but just three stars in all other areas.


Colgate offers a number of options in the mouthwash department. These include its Dry Mouth Relief, Optic White, Gentle Care, plus one designed for kids. There are also a number of different flavours from ‘Peppermint’ to ‘Fresh Tea’. Its Total Advanced Pro-Shield mouthwash is stated to provide up to 12-hour protection against germs with an alcohol-free formula. Sizes range from 500ml to 1L, and 250ml for the children’s variant. Colgate also has a Savacol Mouth & Throat rinse stated to be an antiseptic mouth and throat rinse to help assist in the treatment of medical-diagnosed gingivitis.

  • Colgate was another brand to score four stars for overall customer satisfaction. It also received four stars for freshness of breath, taste and packaging, with three stars in the other categories.


Coles has a very modest line-up when it comes to mouthwash. Keeping it simple, it offers just one mouthwash at the time of writing. Its Coles Mint Fresh Mouthwash is stated to prevent plaque and gingivitis as well as fight germs that cause bad breath. It’s made in Australia and available in a 500ml bottle. If you find it hard to make a decision about which flavour of mouthwash to get, then Coles certainly makes it quite easy.

  • Coles was left with three stars for overall satisfaction and all other categories except packaging and value for money, where it scored four stars.

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: 28%
  • Effectiveness: 26%
  • Taste: 21%
  • Value for money: 13%
  • Packaging: 11%

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

Freshness of breath

The most important driver of satisfaction was freshness of breath. This is typically a benefit that most brands claim to deliver. According to the mouthwash experts, 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 good mouthwash that helps to reduce bad breath is beneficial (for everyone).

The second most important factor 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, 45% said they use mouthwash for health reasons (e.g. gum disease/cavities/plaque), 25% use it out of habit, 21% use it to get rid of bad breath, and 5% use it because their family and friends do. With a huge line-up of options, there’s certainly plenty of choice if one brand doesn’t cut it.


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. Don’t assume that just because the taste is strong, it must be a good thing in terms of effectiveness.

Value for money

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. It was tough for the five brands in our review to win over consumers in this category, with most receiving just three stars. 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.


Last but not least – packaging. It may not directly affect the end result, but it certainly helps with the overall experience. With 41% 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.

Which mouthwash should I buy?

So, there you have it – ALDI Dentitex has been rated the number one brand of mouthwash, receiving a five-star review for overall customer satisfaction for the second year in a row. It seems ALDI provides a good balance between effectiveness and value for Aussie consumers, whether it’s groceries, cleaning products or personal hygiene.

The brand of mouthwash you place in your shopping basket with 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!
