The Importance of Mouthwash for Kids

Mouthwash is usually associated with adult dental care, but mouthwash can be a great addition to your child’s oral hygiene routine. You might want to add mouthwash to your child’s brushing and flossing routine for several reasons.

Some benefits of mouthwash for kids include:

  • Freshens bad breath
  • Strengthens teeth and fights cavities 
  • Promotes healthy gums and prevents gingivitis
  • Washes away food particles from areas that are hard for a child to clean

Mouthwash can be especially beneficial for kids who wear braces or other dental appliances. Swishing with mouthwash prevents bacteria and plaque buildup. And this reduces the risk of tooth decay.

What is the Best Age for Kids to Start Using Mouthwash?

According to the American Dental Association (ADA), children should be at least 6 years old before using mouthwash.1 If your dentist recommends mouthwash for your child before age 6, the ADA recommends following the dentist’s advice.

Kids under 6 may still need to fully develop swallowing reflexes. This can cause them to accidentally swallow mouthwash. If kids drink mouthwash in large amounts, it can lead to nausea and vomiting.

Tips to Help Kids Use Mouthwash Safely

When properly used, mouthwash strengthens your kid’s teeth and protects them from cavities. Your child should brush their teeth and floss before using mouthwash.

Here’s how to use it safely:

  • Store mouthwash where your child can’t reach — this deters them from drinking it.
  • Supervise kids younger than 12 — this ensures they’re spitting the mouthwash into the sink and not swallowing it.
  • Read and follow the directions on the bottle — some formulas are for once-daily use, while others are safe to use twice daily.
  • Use the recommended amount — if the mouthwash bottle doesn’t have a dosing cup, use only a small amount.

Why Trust Our Review?

We specialize in sharing researched, informative articles about dentistry, including transparent reviews you can trust. We know that, as parents, there are many things you’d rather spend your time on than researching your kid’s mouthwash.

To create this review, we checked the ingredients in every product and referred to peer-reviewed scientific articles. We also read through user reviews (good and bad) and investigated each brand.


Mouthwash is a great way to add cavity protection to children’s brushing and flossing routines. However, mouthwash made for adults may not be suitable for children.

In addition to being alcohol-free, many mouthwashes we recommend are free from artificial ingredients that may be harmful if swallowed.

Even if your child uses a mouthwash formulated for kids, it’s important to supervise them until they can swish and spit on their own. Always read the directions on the mouthwash bottle and talk to your dentist about any concerns.
