Even though you have been brushing and flossing your teeth twice a day regularly, you might be surprised to know that your dental hygiene is still being compromised. Why? That’s because you are still using your old, weary toothbrush! Yes, using the same toothbrush for months on end is bad for your teeth.

When to change toothbrush?

Wondering when do you need to buy a new toothbrush? Many dentists suggest that one should change their toothbrush approximately every 3-4 months or sooner if the bristles are frayed, or if you have been sick for a while. And why is that so? Because once the bristles become worn out and frayed, the toothbrush may lose its effectiveness. Various clinical studies have shown that a new toothbrush is more efficient in removing plaque. Thus, ensuring that your brush is doing its best to keep your teeth healthy and clean!

Not replacing your toothbrush at the right time will cause dental problems. The frayed bristles of an old toothbrush do not kill the harmful bacteria in your mouth. Neither does it protect your teeth against decay and plaque. A new toothbrush is gentle on your teeth and gums and can brush out food particles and germs more easily and effectively.

Choosing the right toothbrush

Did you know there are two types of toothbrushes? A manual toothbrush and an electric one.

A manual toothbrush is the commonly used variant. It has a simple design and you have complete control over how much pressure it puts on your gums and teeth.

An electric toothbrush, on the other hand, requires charging. Due to the rotating movement of the bristles, it becomes easier for you to clean between your teeth and along the gum line.

Choose whichever feels comfortable and makes you want to brush your teeth twice daily.


Maintaining your toothbrush

Want to ensure that your toothbrush stays in good shape? The American Dental Association recommends that after brushing your teeth you should rinse the toothbrush under running tap water. How will it help? Water will wash away saliva and traces of toothpaste. Keeping the used toothbrush in a closed container can cause bacteria to build up. It is advisable that you always position your toothbrush vertically after use so that the bristles can dry.


To ensure that your oral health does not suffer, practice dental hygiene regularly and change toothbrush every three months.
