When Should I Change My Toothbrush? (Electric Toothbrush Heads & Manual Brushes)

We all know the importance of brushing twice a day—but how often do you think about changing your toothbrush? Whether you’re a fan of the good old manual brush or swear by your electric toothbrush, swapping out your brush regularly is key to maintaining a healthy smile.

Let’s explore when, why, and how to keep your brushing routine fresh and effective.

📅 How Often Should You Change Your Toothbrush? 🪥

The general rule: every 3 months.

✔️ Manual Toothbrush: Replace every 3 months or sooner if the bristles are frayed.
✔️ Electric Toothbrush Head: Swap out the brush head every 3 months as well, or sooner if it shows signs of wear.

👉 Why 3 months?
Over time, bristles lose their shape and stiffness, which means they’re no longer doing a good job cleaning your teeth and gums. Worn bristles can also become sharp and cause gum irritation.

🚨 Signs It’s Time to Replace Your Toothbrush Sooner ⏳

Sometimes you might need to replace your toothbrush or electric head even before the 3-month mark. Keep an eye out for:

• Frayed, bent, or splayed bristles
• Discolouration of the bristles
• Build-up of toothpaste or debris at the base
• A lingering bad smell
• Recent illness or infection (to avoid reintroducing bacteria)
• If you’ve been unwell (like having a cold, flu, or sore throat), it’s a good idea to replace your toothbrush immediately—even if it’s relatively new.

⚡ Manual vs Electric: Is There a Difference in Lifespan?

Surprisingly, both need replacing around the same time.
The key difference is that some electric toothbrush heads come with indicator bristles that fade in colour to let you know it’s time to switch. This is a handy reminder if you’re someone who tends to forget.

Electric toothbrushes can sometimes wear out a little faster due to the added motion and pressure, so always check your bristles regularly.

✨ Why Regular Replacement Matters

Better Cleaning: Old, worn bristles can’t effectively remove plaque.
Healthier Gums: Damaged bristles can be harsh on delicate gum tissue.
Bacteria Build-up: Over time, toothbrushes can collect bacteria, especially if not stored properly.
A fresh toothbrush gives your smile its best defence!

💡 Pro Tip: Set a Reminder

If you’re likely to forget when you last changed your toothbrush, try:

• Setting a reminder on your phone every 3 months
• Changing your brush at the start of each new season
• Buying multi-packs so you always have a spare on hand
