Teaching little ones to brush their teeth properly is basically a never-ending responsibility that doesn't just fall on the dentist. Nope, it's up to us, the parents, to teach our children how to make sure their teeth are clean and their toothbrush isn't just used for lobbing toothpaste all over the bathroom counter and sink.

What most first-time parents don't realize is that lessons on brushing teeth don't just stop when your toddler can grasp a toothbrush and make circular motions all over their mouths. Nope, you have to keep beating the dental hygiene drum well into childhood.

And that, my cavity-free friends, is why this DIY dentist kit is a brilliant mom hack (and not just because you can buy all of the supplies at Dollar Tree for less than $5).
