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

Everyone recognises that daily brushing twice produces excellent results; however, most people do not think about changing their toothbrush. Regular toothbrush exchanges are essential for maintaining healthy teeth despite your preference for manual or electric toothbrushes.
Let’s explore the proper timing and methods and reasons to maintain fresh and effective brushing.
📅 How Often Should You Change Your Toothbrush? 🪥
The general rule: every 3 months.
Replace manual toothbrushes both when bristles show wear and when bristles reach the end of their three-month replacement period.
The brush head of electric toothbrushes should be changed every three months or before if wear signs appear.
🚨 Signs It’s Time to Replace Your Toothbrush Sooner ⏳
You should change your toothbrush or electric head before reaching the standard three-month replacement period in certain cases. Check for these indicators to replace your toothbrush.
- 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 are ill with a cold, flu or sore throat, it is best to replace your toothbrush even if it is new.
⚡ Manual vs Electric: Is There a Difference in Lifespan?
Surprisingly, both need replacing around the same time.
The main distinction between electric toothbrush heads lies in the colour-changing bristles that indicate replacement time. Users who tend to forget will find this feature helpful.
Check your electric toothbrush bristles frequently because the device’s motion and pressure can make them wear out faster.
Regular toothbrush replacement offers several advantages which improve oral health.
Old bristles that show wear will not efficiently remove plaque from teeth.
The bristles become too harsh to safely touch the gums when they become damaged.
Bacteria Build-up: Over time, toothbrushes can collect bacteria, especially if not stored properly.
A new toothbrush provides your teeth with their best defence against harm.
💡 Pro Tip: Set a Reminder 🗓
Set reminders on your phone every three months if you tend to forget when you last replaced your toothbrush.
- Start each new season by replacing your toothbrush
- Replace your toothbrush at the start of each new season
- The purchase of multiple toothbrush packs ensures you always have extra toothbrushes available.
