Brushing your teeth and replacing your toothbrush

We all know that brushing and flossing regularly is essential for a healthy smile.

But did you know that replacing your toothbrush plays an equally important role in maintaining good oral hygiene?
How many times have you looked at your toothbrush and thought, “It still looks fine. I’ll keep using it a little longer,” only to realize months have passed? It happens to most people. However, keeping your toothbrush too long can affect both your oral health and your overall well-being.

How often should you replace your toothbrush?

Most dental professionals including our team at Mydent Mondzorg Centrum Rotterdam recommend replacing your toothbrush or electric brush head every three to four months. That’s because toothbrush bristles gradually lose their shape and stiffness, which makes them less effective at removing plaque, food particles, and bacteria.

You should also replace your toothbrush sooner if:

  • The bristles are frayed or splayed.
  • You’ve been ill (to avoid reinfection).
  • The brush looks worn or smells musty.

Some modern toothbrushes have indicator bristles that fade in color when it’s time for a replacement a simple but helpful reminder.

Why is replacing your toothbrush so important?

A worn-out toothbrush doesn’t just clean less effectively it can actually harm your gums and enamel. Overused bristles become sharp and rough, which can irritate your gum tissue and cause small scratches on the tooth surface.

Even more importantly, toothbrushes can collect bacteria, mold, and yeast over time. When you keep brushing with an old toothbrush, those microorganisms can re-enter your mouth — something you definitely want to avoid.

Replacing your toothbrush on time helps to:

  • Maintain optimal plaque control.
  • Prevent gum inflammation (gingivitis).
  • Reduce bad breath.
  • Support a fresh, clean feeling after every brushing session.

Choosing the right toothbrush

At Mydent Mondzorg Centrum Rotterdam, we recommend:

  • Using a soft-bristled brush: it’s gentle on gums but still cleans effectively.
  • Considering an electric toothbrush if you struggle with plaque buildup or hand dexterity.
  • Storing your brush upright and allowing it to air dry (avoid covering it).
  • Choosing age-appropriate brushes for children: smaller heads and soft bristles make brushing fun and safe.


Remember: it’s not about how hard you brush, but how thoroughly and regularly you do it.

How to brush properly

A few practical tips from our dental hygienists in Rotterdam:

  1. Brush twice daily for at least two minutes.
  2. Use small, circular motions don’t scrub aggressively.
  3. Don’t forget to brush your tongue and gum line.
  4. Replace your toothbrush regularly to ensure effective cleaning.
