When to Start Brushing Baby Teeth

It is recommended that you start brushing baby teeth as soon as that first tooth erupts. Use an extra-soft bristled toothbrushes and a pea-sized amount of non-fluoride toothpaste to gently clean baby teeth and tender gums.

The Oral-B and Crest Baby Training Toothpaste and Toothbrush Kit features a manual toothbrush with extra-soft bristles for a gentle clean and a mild strawberry flavored toothpaste that’s free of artificial flavors, sodium lauryl sulfate, sweeteners, and dyes.

When do Adult Teeth Come In?

The first adult molars start to come in around age 6. At this stage, it’s important for them to brush with a fluoridated toothpaste to better fight off cavities and strengthen enamel. ADA-approved Crest Kids Enamel + Cavity Protection Strawberry Toothpaste helps prevent cavities and rebuilds tooth density for stronger teeth. Plus, it’s the best protection for kids from Kid's Crest, the #1 kids' toothpaste brand in America.

By the time your child reaches the age of 13, most of their adult teeth should have fully emerged, excluding the third molars, commonly referred to as wisdom teeth, which typically appear during the late teenage years or early twenties.
