ALDI Dentitex stays fresh in mouthwash ratings for 3rd year running

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 almost 1,400 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.

ALDI Dentitex is maintaining a toothy grin for the third year in a row, after being the only brand to score a five-star review for overall satisfaction. It additionally got top marks for effectiveness, taste and value for money.

Mouthwash Brands

ALDI Dentitex

ALDI Dentitex mouthwash

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 scored five-star reviews for most categories, including effectiveness, taste, value for money and overall satisfaction. It got four stars everywhere else.


Sensodyne mouthwash

Sensodyne aims to help those with sensitive teeth achieve healthy gums, as well as relieve discomfort caused by consuming certain types of foods or drinks, like coffee or sodas. Teeth sensitivity typically occurs when a sharp pain is caused by brushing teeth as well as drinking or eating something cold or hot, or sweet or sour. The brand currently offers just one product, the Sensodyne Gentle Mouthwash. This mouthwash is alcohol-free and said to be long-lasting.

  • Sensodyne achieved five stars for effectiveness and taste, and four stars for overall satisfaction and the majority of other categories. It got three stars for value for money.


Listerine mouthwash

Listerine has a large range of mouthwashes, with its line-up targeting different needs, including anti-cavity, 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 was rated five stars for freshness of breath, plus four stars for overall satisfaction and most other categories. It got three stars for value for money.

Oral B

Oral B mouthwash

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 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 achieved five-star reviews for freshness of breath and packaging, before ending on four stars for overall satisfaction and most other categories. The only exception was value for money, where it got three stars.


Colgate mouthwash

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.

Colgate also has a Savacol Mouth & Throat rinse, which is described as an antiseptic mouth and throat rinse to help assist in the treatment of medical-diagnosed gingivitis.

  • Colgate scored four stars for taste and packaging, plus three stars for overall satisfaction and the rest of the board.


Coles mouthwash

Coles has a fairly modest line-up when it comes to mouthwash. The supermarket brand keeps it simple with three types of mouthwash. 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.

  • Coles achieved four stars for value for money, before rounding up the scores on a moderate three stars for overall satisfaction and everywhere else.

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: 24%
  • Freshness of breath: 21%
  • Value for money: 19%
  • Taste: 19%
  • Packaging: 17%

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


What is the most effective mouthwash

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 50% 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%).

Freshness of breath

No one likes the feeling of morning breath, let alone the smell. So, it’s no surprise that freshness of breath ranked as one of the most important factors affecting customer satisfaction. After all, nearly one in five respondents (18%) said they use mouthwash to get rid of bad breath. Almost a third (29%) additionally prefer an alcohol-free mouthwash, proving a fresh breath is also about how your mouth feels afterward.

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. With 44% 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?

There you have it – ALDI Dentitex has been rated the number one brand of mouthwash, receiving a five-star review for overall satisfaction for the third 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 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!

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.

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.

A rated brand may receive a ‘N/A’ (Not Applicable) rating if it does not receive the minimum number of responses for that criteria.
