Signs That You Need to Change Your Toothbrush

Your toothbrush is a key part of your daily oral hygiene routine, but it doesn’t last forever. Over time, it becomes less effective — and even unhygienic. Here are some clear signs that it’s time to replace it:

1. Frayed Bristles

If the bristles are bent, split, or splayed outwards, they can no longer clean effectively. Worn bristles can miss plaque buildup and cause gum irritation.

2. Discolouration

A faded or stained toothbrush head may be a sign of bacterial buildup or contamination. Discolouration can occur from toothpaste residue, mouth bacteria, or even mold.

3. Accumulation of Debris or Odor

Noticing an unpleasant smell or particles stuck between the bristles? That’s a hygiene red flag. A toothbrush should never smell bad — it means it’s harboring bacteria.

4. Recent Illness

After recovering from a cold, flu, or other infections, it’s best to toss your old brush. Germs can linger on bristles and cause reinfection.

5. Time-Based Replacement

Dental experts say you should replace your toothbrush every 3 months — even if it still looks “okay.” Regular replacement ensures optimal cleaning performance and hygiene.

✅ Pro Tip:

Keep a spare toothbrush on hand so you’re never caught off guard. And always store your brush upright in a dry, open space to prevent bacterial growth.
