IN A HURRY? HERE’S OUR TOP PICKS…

When can kids start using mouthwash

In terms of when kids can start using a mouthwash, most kids are able to start using a mouthwash around the age of 6.  That is because children under 6 years old generally lack the reflexes and motor control to gargle and spit.

A good way to see if your child is ready for mouthwash is by letting them practice with plain water before introducing a kid-specific mouthwash.  Once you think they are ready for a mouthwash, check with your child’s dentist first to see if your child will benefit from adding mouthwash to their daily dental routine.

What does mouthwash exactly do?

You may be wondering if alcohol-free mouthwash actually kills germs. Absolutely. A kid-friendly mouthwash can do the same job as a mouthwash for adults.  That’s because the key ingredient in most kids’ mouthwashes is sodium fluoride.

An effective mouthwash, like the ones on this list, can freshen breath, kill bacteria, and prevent tooth decay.  Along with brushing twice-a-day, mouthwash can help prevent plaque from forming and help remove any particles that are leftover after kids are done brushing and flossing.

Choosing a mouthwash for kids

No matter which mouthwash you choose, here are three things to keep in mind when selecting a mouthwash for your child:

Choose a mouthwash that is alcohol-free. Alcohol can be found in many types of mouthwash for adults, and while it is effective at killing bacteria, it is not suitable for kids. Swallowing small amounts isn’t good for their growing bodies, so opt for an alcohol-free mouthwash until they are older.

Look for the ADA Seal.  A mouthwash that has been approved by the American Dental Association (ADA) has been tested to ensure the product is not only safe but effective too.

Let them choose the flavor.  Not all kids love mint, so let them choose the flavor.  Most kids’ mouthwash is available in kid-friendly flavors such as bubble gum. And know that no matter what flavor they choose, they’ll still get a great clean and fresher breath.

Tips for using a mouthwash

It may take a little time for your child to get used to using mouthwash correctly.  Here are some tips for you to keep in mind when having your child incorporate a mouthwash into their routine:

Supervise children while they use mouthwash.  For kids under 12, make sure you keep an eye on them while they use it.  You want to ensure they aren’t accidentally swallowing or that they are skipping straight to mouthwash, forgoing the brushing and flossing part!

Have your child swish for 60 seconds.  Set a timer or play a song to help them know when to stop.

Store in a locked cabinet or a high shelf.  Mouthwashes for kids can taste good and young children might be tempted to reach for it and drink some when mom and dad aren’t around.  Be sure to store mouthwash out of their reach.

Frequently Asked Questions

Q: My child brushes and flosses. Do they really need a mouthwash?

A:  While mouthwash isn’t a must-have for children, it can greatly help kids get a better clean.  For kids with braces, it can help get into some of the harder to reach spaces, and for younger kids (over the age of 6 though!) it can help get into the places they might have missed.

Kids with cavity-prone teeth might also benefit from adding a fluoride (but alcohol-free) mouthwash to their dental routine, but again, be sure to check with your child’s dentist to see if it’s right for them.

Q: Should I get a fluoride or fluoride-free mouthwash?

A: Opting for a mouthwash with fluoride is going to help prevent cavities and plaque from forming.  Just be sure the kids don’t swallow! While ingesting a little fluoride won’t hurt, too much isn’t good for kids.

If your children are very young and haven’t gotten the hang of gargling and spitting, choose a fluoride-free mouthwash until they are older.  It will still aid in rinsing away particles for a better clean.

Q: What’s the difference between cosmetic and therapeutic mouthwash?

A:  Therapeutic mouthwash helps prevent tooth decay, kills germs that cause bad breath and helps prevent plaque build-up.  All of the mouthwashes on our list are considered therapeutic mouthwashes. Cosmetic mouthwash, on the other hand, will freshen breath, but they won’t help with preventing cavities, plaque build-up or kill germs that cause bad breath.

Bottom Line

When it comes to the best mouthwash for kids, any of these picks on our list will do a great job of preventing cavities, freshening breath and keeping kids mouths happy and healthy.  Our top pick though is the Listerine Smart Rinse. Kids will love the flavor and the fun characters on the bottle. And you’ll love that you won’t be making as many trips to the dentist.

For moms and dads who are looking for a fluoride-free rinse, definitely consider the Hello Oral Care Kids Rinse. Kids really liked the watermelon and mint flavors and you’ll be happy not having to fight your kids to rinse after brushing and flossing.
