Is Mouthwash Safe for Kids and When Should They Start Using It?

You’re standing in the oral care aisle, your kid is eyeing that bright blue bubble gum rinse, and you’re wondering: Is this actually something they should be using? It’s a fair question, and you’re definitely not the first parent to pause in that aisle and think twice. The short answer is that mouthwash is not a must-have for little kids, and there’s a specific age where it starts to make sense.

At Silicon Beach Pediatric Dental in Culver City, Dr. Ray and Dr. Hayley takes a simple approach to oral hygiene questions like this one. When it comes to our pediatric dentistry services, the goal is always to help your family build healthy habits that actually work for your household, not a one-size-fits-all checklist.

Why Mouthwash Is Not for Toddlers

The main reason little kids should skip mouthwash has nothing to do with the ingredients being harmful in normal use. It comes down to one simple thing: swallowing. Most toddlers and preschoolers are not developmentally ready to swish and spit reliably, and mouthwash is not meant to be swallowed.

The American Academy of Pediatrics advises that children should not use mouthwash until age 6, when they are able to properly swish and spit. Before that age, it really depends on how able your child is to rinse and spit, and this can be discussed on an individual basis. 

What to Focus on Instead

For kids under 6, brushing twice a day and flossing nightly is the real work. A soft-bristled toothbrush, a small amount of fluoride toothpaste, and an adult doing the actual brushing, followed by flossing are what matter most.Our dental exams and cleanings help reinforce those habits at every visit, and Dr. Ray and Dr. Hayley will walk you through the details when your child comes in.

Most kids are not ready to brush their own teeth effectively until around age 7 or 8. Until then, you are doing the brushing and in some cases supervising it, and your child is mostly practicing the routine.

Do Not Forget Flossing

Once your child has teeth that touch, flossing matters. It is the one area that brushing simply cannot cover on its own. We have a whole post dedicated to whether your child should be flossing if you want to dig into the details.

When Mouthwash Actually Makes Sense

Once your child hits 6 and can reliably spit without being reminded, an alcohol-free, fluoride rinse can be a nice add-on to their routine. Here is what to look for at that stage:

  • Alcohol-free, fluoride rinse formula: Look for this clearly on the label before putting it in the cart. A fluoride rinse is key. 
  • ADA Seal of Acceptance: A rinse with this seal has been tested for safety and effectiveness.
  • Supervised use: Even at 6 or 7, do the first few rounds together to make sure the spitting is actually happening.

The keyword here is add-on. Mouthwash at this stage is a supplement to brushing and flossing, not a replacement.

A Note on Fluoride and the Bigger Picture

Every family has a different comfort level with fluoride, and Dr. Ray and Dr. Hayley understand that. They do not believe in handing every family the same script. What works for one kid in one household may not be the right fit for another. That is exactly why regular check-ins with a pediatric dentist matter. It allows the advice you get to be tailored to your child and household, not just pulled from a general guidelines sheet.

The same thinking applies here. According to the American Academy of Pediatrics, children should not use mouthwash until age 6, and mouthwash should always be stored out of reach when there are young children in the home. That is a solid baseline, but what comes after 6 is something worth discussing with your child’s dentist based on their specific cavity history and oral health habits.
