5 Mouthwash Uses You Probably Didn’t Know About

We all know what mouthwash is for – it’s in the name! But fresh breath is just the beginning, and that bottle in your bathroom cupboard has a few extra tricks up its sleeve. Here are five surprising ways your mouthwash can do more than you think. 

1. Disinfect your toothbrush in minutes 

If your mouthwash is antibacterial, you can use it to sanitise your toothbrush. Just fill a cup with mouthwash and soak the toothbrush head for around 10 minutes to help reduce bacteria build‑up between brushes. 

2. Clean minor cuts and blisters 

Some mouthwashes have antiseptic properties and may be used occasionally on very minor cuts or blisters. Apply a small amount to clean skin, then rinse off with water. This should only be done with an alcohol‑free mouthwash, as alcohol can irritate the skin and delay healing. 

3. Freshen reusable water bottles 

Mouthwash can help reduce some of the bacteria that cause odours in water bottles. It isn’t a substitute for proper washing and can’t prevent mould, but a quick rinse with mouthwash in between cleans can help give bottles a temporary refresh. 

4. Heal dandruff-prone scalps 

When applied to the scalp and rinsed out after shampooing, some mouthwashes with antifungal properties may help reduce the yeast often linked to dandruff. Take care to avoid contact with your eyes, as mouthwash can irritate them! 

5. Reduce bacteria buildup on oral appliances 

Mouthwash can be used as a quick soak to freshen oral appliances such as mouthguards, dentures, retainers, or aligners. While it shouldn’t replace regular, thorough cleaning with the products recommended for your appliance, it’s useful in a pinch. 

A word of caution 

Now you know what else your mouthwash is capable of! Just remember, these aren’t its intended uses, and mouthwash shouldn’t replace proper cleaning or treatment. Think of them as handy emergency solutions for when you’re short on time or really stuck — and when in doubt, always consult your dentist.
