“How often should you change toothbrush?”

It’s a question everyone asks.

We all know the rule of thumb when it comes to brushing best practices. Brushing three times a day 30 minutes after meals. However, only a few people know and implement toothbrush hygiene best practices.  

Here are two rules of thumb when it comes to changing your toothbrush.

1. Change your toothbrush when the bristles start to show wear and tear
2. Change toothbrush every 3 months as recommended by dentists 

Why do you need to change toothbrushes?

The Real Reason Why You Need to Change Toothbrush

The most obvious reason why you need to change your toothbrush often is that an old and damaged toothbrush is less effective in cleaning. But why?

  • Worn-out bristles
  • Gums damage
  • Bacterial infection

Worn-out Bristles

Worn-out bristles are almost useless for cleaning teeth and gums. If you look closely, you’ll notice that the bristles are splayed. It’s almost like they’re avoiding contact with your teeth. When brushing, the fine bristle tips are not rubbing on your teeth effectively.

Brushing with worn-out bristles feels like when laser beams are deflected from a mirror. Sure, the mirror heats up but the full effect of the beam is reduced by more than half. The worst part about this is the bounced laser. The reflected laser harms everything around the mirror. 

Speaking of harm, here’s the next reason why you need to change your toothbrush frequently.  

It WILL Hurt Your Teeth and Gums

The quality of the toothbrush doesn’t matter if you overuse it. Any toothbrush you use for too long will eventually hurt your gums. Going along with the reflecting laser analogy, every bristle that bounced off of your teeth will rub on your gums in a damaging way.

You will also notice the difference in force or strokes when you brush with a worn-out brush. You will start brushing more forcefully. Because the brush doesn’t feel efficient on the teeth, you’ll unconsciously go harder. This not only doesn’t clean your teeth efficiently, but it also ends up hurting your gums. 

Worn out bristles can be very damaging to your teeth and gums. Toothbrush manufacturers design the bristles to be rounded so they don’t cause pain or abrasions. Old bristles develop a sharp tip that can cut your gums and scrape at your teeth enamel.

With bleeding gums, you’re prone to oral bacterial infection. Which leads us to the next reason why you need to change your toothbrush.   

Bacterial Infection

Worn out bristles can hurt your gums and make you prone to bacteria, but that’s not the only way to get a bacterial infection. An old toothbrush is a magnet for bacteria. Our mouth is one of the dirtiest parts of our body. It carries 6 billion bacteria – some healthy some bad.

An old toothbrush compiles all the bacteria throughout the time. If you wait too long to change it, you’re bringing months of bacteria accumulation into your mouth. 

Even if you sanitize your toothbrush after use, it’s still not a good idea to overextend its usage past the expiration.  

How to Make toothbrush last longer

Is there a way to brush so as not to damage your toothbrush prematurely? How long should a toothbrush last?

Look for the two signs mentioned above of a toothbrush going bad. There are a few ways to make a toothbrush last:

1. Brush using gentle strokes
2. Buy a high-quality and durable brush

Keep in mind that just because you know how to make it last, it doesn’t mean you should keep it longer than recommended. Dentists recommend changing your toothbrush every 3 months.
