We’ve all seen brightly coloured bottles of mouthwash lining the shelves of supermarkets, but you might not realise how to use mouthwash or what the benefits of doing so are. Mouthwash is a liquid product you rinse your mouth with after brushing your teeth. Brushing just your teeth only targets 25% of your mouth*, whereas mouthwash targets virtually 100%. Using a mouthwash that contains fluoride – such as LISTERINE® Total Care 10 in 1 – can help to:
Strengthen enamel to protect against tooth decay
Freshen breath
Reduce plaque and prevent tartar.
When you rinse your mouth with a mouthwash, it reaches the areas of your mouth that brushing often misses, including the teeth, gums and tongue.Here, we’ll talk you through how to use mouthwash and provide a quick summary of things to remember when using it to help keep your mouth clean and fresh.

A step-by-step guide on how to use mouthwash
The key to getting the most out of mouthwash is knowing how to use it properly and effectively. While this can vary between brands – and some may need expert advice from your dentist – most tend to follow the same rules. For example:
How much mouthwash to use – the ideal amount of mouthwash varies depending on the brand and type of mouthwash you are using. Always refer to the bottle label for instructions.
How long to use mouthwash for – swish and gargle mouthwash for between 30 to 60 seconds each time you use it. This can vary though, so always check and follow the instructions on the labelling.
Spit out mouthwash – you should not swallow mouthwash, so make sure you always spit it out after use.
Remember, no matter how effective mouthwash is, it’s not a replacement for brushing and flossing. It should be an additional step in your oral hygiene routine.
When to use mouthwash
You should use mouthwash or a mouth rinse as part of your everyday oral hygiene routine to get the most out of its use. After you’ve finished brushing your teeth, spit out your toothpaste, but do not rinse your mouth with water immediately after. This helps avoid removing fluoride from your toothpaste. We recommend rinsing with a fluoride containing mouthwash like LISTERINE® Total Care 10 in 1 after brushing to help clean the areas your toothbrush can’t reach, strengthen your tooth enamel, and help fight bacteria that can cause tooth decay.
How often to use mouthwash
Most mouthwash brands recommend twice daily usage, although it’s always best to check the label for brand-specific advice. Using an essential oil containing mouthwash, such as LISTERINE®, as part of your everyday routine can have several benefits, including:
Protects against cavities and tooth decay
Kills bacteria to reduce plaque
Prevents tartar
Cleans between the teeth
Protects the gums
Freshens breath
Some mouthwashes can also remove stains to help whiten teeth.
