Find out when to start your child on an electric toothbrush and how to choose the right one for their age, from toddler to tween.

Quick answer

You can introduce an electric toothbrush as early as age 2, but the right model depends on your child's age and dental stage. For toddlers (ages 2-4), choose a kid-sized handle with gentle bristles and a 2-minute timer. For tweens (ages 7+), look for a brush with multiple cleaning modes and a comfortable grip. Made By Dentists offers dentist-designed options for both age groups.

When to start using an electric toothbrush

Most dentists agree that children can start using an electric toothbrush around age 2, when their first set of teeth is fully in. At this stage, the goal is to build a positive brushing habit rather than achieve perfect technique. A brush with a small, soft head and a built-in timer helps make the experience fun and effective.

For children ages 7 and up, an electric toothbrush can address more complex needs like plaque removal and gingivitis prevention. This is also the age when kids may get braces, so a brush with gentle but powerful cleaning becomes especially useful.

What to look for in a kids' electric toothbrush

Focus on three key features: brush head size, bristle softness, and a timer. A compact head fits small mouths and reaches back teeth easily. Soft bristles protect developing enamel and sensitive gums. A 2-minute timer ensures your child brushes for the dentist-recommended duration. For older kids, extra cleaning modes can help transition from a basic to a more thorough routine.

How to choose the right brush for your child

Age 2-4: Start with a toddler brush: Look for a brush with a compact head, soft bristles, and a simple 2-minute timer. The Bulldog Electric Toothbrush is designed specifically for this age group with a kid-sized grip and gentle cleaning. Prioritize comfort and habit-building over advanced features.
Age 5-6: Transition to a larger brush: If your child has lost some baby teeth, a brush with a slightly larger head and a standard timer may work better. The Bulldog brush still fits many 5-6 year olds, but you can also consider a brush with replaceable heads for longer use. Check that the brush head still fits comfortably in the mouth.
Age 7+: Choose a tween brush with modes: At this stage, a brush like the Bad To The Bone Electric Toothbrush offers two cleaning modes and a comfortable grip. It's designed for the in-between years when kids may have braces or mixed teeth. Look for multiple modes and a brush that can handle braces if needed.
