How Often Should You Replace a Child’s Toothbrush?
Share
Toothbrushes don’t last forever — especially when they’re used (and chewed!) by little ones. If your child’s toothbrush is looking frayed, flattened, or just plain gross, it’s probably long overdue for a replacement.
In this blog, we’ll explain exactly how often to replace a child’s toothbrush, why it matters for brushing hygiene, and how our toothbrush subscription service can make life easier for busy parents.
🕒 So, How Often Should You Replace a Child’s Toothbrush?
Every 3 months is the general rule — and for good reason. The New Zealand Dental Association (NZDA) and American Dental Association (ADA) agree: replacing a toothbrush every 3 months helps maintain effective plaque removal and healthy brushing habits.
But there are times when you might want to swap it out even sooner.
⚠️ Signs It’s Time for a New Toothbrush
Kids can be rough on their brushes. If you notice any of these signs, don’t wait the full 3 months:
- Bristles are frayed, bent, or flattened
- Brush looks chewed or worn out
- Your child has been sick (especially with strep throat or a cold)
- The brush is visibly dirty or mouldy (yes, it happens!)
- Your child says it feels "scratchy" or uncomfortable
A worn-out toothbrush doesn’t clean effectively — and can actually irritate gums or harbor bacteria.
For more details, check out the Mayo Clinic’s toothbrush hygiene advice.
💡 Why Replacing Matters: It’s About More Than Just Looks
Old toothbrushes aren’t just ineffective — they’re unhygienic.
Here's why brushing hygiene matters:
- Worn bristles can’t remove plaque properly
- Bacteria build-up can spread illness or gum infection
- Frayed brushes can damage delicate gums
- Fresh brushes encourage better brushing habits in kids
In short, keeping toothbrushes fresh = cleaner mouths, healthier smiles.
