HERE'S THE SCOOP ON
Replacing Brush Heads Regularly
We recommend changing your brush head every 3 months, and your dentist does, too. Spoiler alert: it's not a marketing tactic. We've put together the top four reasons for regularly replacing your brush heads.
Bacteria Build-Up
Over time, your toothbrush head becomes a breeding ground for bacteria which can increase the risk for cavities, gum disease, and bad breath. No thanks.
Irritated Gums
Bristles become less soft over time, which can lead to gum irritation. It’s kind of like using a razor— you’re more likely to hurt yourself with a dull razor than a new one.
Less Effective Clean
As bristles wear down with use, your toothbrush becomes less effective at removing plaque. Plaque build-up creates tartar, which turns into an unpleasant trip to the dentist.
Catch a Cold
If you're feeling under the weather, you should replace your brush head afterwords to prevent reinfecting yourself.

Metal-Free Brush Heads (and why it matters)
Most people don’t know that standard toothbrushes contain metal underneath the bristles. Why does that matter? We’re so glad you asked. Over time, the metal corrodes and can release harmful toxins that you can ingest when you brush.
