Do I Need to Rinse?
Mouthwash is not a substitute for brushing and flossing. But if you have trouble doing those correctly, rinsing can aid in keeping your teeth and gums healthy. Fluoride rinses help prevent tooth decay.
“Mouthwashes, when added to a good home care regimen of brushing and flossing, can target a condition that you are facing,” Wolff says. “You don’t swish for 2 minutes with a whitening mouthwash and suddenly have white teeth. But if you brush well and keep the plaque off of them and use that mouthwash as part of the package, you do get whiter teeth.”
A mouth rinse won’t cure serious problems, though. If you have regular bleeding of your gums or consistently bad breath, for example, make sure to see your dentist. They might prescribe a mouthwash that’s stronger than the kind you buy over the counter.
Read the labels carefully on over-the-counter types. Ingredients — and the benefits they provide — vary by brand.
They usually include one or more of these:
Fluoride. It helps reduce tooth decay and prevent cavities.
Antimicrobials. They kill the bacteria that cause certain dental issues.
Astringent salt. It’s a type of deodorizer that can temporarily cover up bad breath.
Odour neutralizers. They can attack the cause of bad breath.
Whiteners, such as peroxide. They can help against stains on your teeth.
How Do I Choose a Mouthwash?
It’s sometimes hard to find one product that ticks all the boxes. “Select a mouthwash based on the largest condition that you need to treat,” Wolff says.
What’s the Best Technique for Mouth Rinsing?
Each product has its own instructions, but here are some tips:
When should I swish with mouthwash? It doesn’t matter if you do it before you brush and floss or after.
How long should I swish? Do it for 30 to 60 seconds. Less than half a minute probably won’t do much. And more than a minute is more than enough.
When will I see results? Be patient. If your mouthwash promises to whiten teeth or help against bleeding gums, it might take a few weeks to deliver.
