School is just around the corner, and while the back to school list is probably as long as your child, we have one more thing to add—a new toothbrush. In the sea of clothes and school supplies you will be swimming through, a new toothbrush should not be forgotten on your child’s back-to-school shopping list.

While you’re adding “toothbrush” to your list, you might be wondering what the best toothbrush for children is. We discuss all of the variables for choosing the right toothbrush:

How often should you change your toothbrush?

The American Dental Association (ADA) recommends that toothbrushes be changed every 3 months. We know that remembering to change your toothbrush every 3 months can prove to be a little challenging. Associating a new toothbrush with important days may help you remember to change it. Here are 4 important times of the year to change your toothbrush: back-to-school, Thanksgiving, Valentine’s Day, end of school.

But did you know that just as important as replacing an old toothbrush, you should make sure that you buy your child the right toothbrush.

Does toothbrush size or shape matter?

While there isn’t a one-size-fits-all best toothbrush for children, the important thing that matters is the size. The appropriate size for your child varies by age. The shape and size of the toothbrush should allow it to fit comfortably in your child’s mouth. This allows them to reach all areas easily. Brushing with a toothbrush that is too large can damage your child’s gums.

Should you clean your toothbrushes?

Toothbrushes should be kept clean. Make sure to rinse the toothbrush after every use, store it in an upright position and allow it to dry until using it again. Keeping a toothbrush in a closed cover can lead to an increased growth of microorganisms due to moisture.

New, clean toothbrushes mean clean teeth and clean teeth mean awesome smiles in those yearbook pictures. Take care of your child’s toothbrush and their teeth this school year!
