Why is it important to change your toothbrush?
Changing your toothbrush or your electric toothbrush head is important because bacteria from your mouth and your bathroom can accumulate on your toothbrush over time. It can affect your dental health and spread infection.
Using a toothbrush with frayed bristles can damage your gums but is also not as effective and will not remove as much plaque as when they are new.
Why do you have to change your toothbrush or toothbrush heads even if they look clean?
They might look clean to you, but if you could get a closer look at it, you would be shocked.
Every time you use your toothbrush, your bristles are exposed to chemicals from your toothpaste plus the friction against your teeth make your bristles weaker after each use. They will become less effective to remove plaque and bacteria can build up on your bristles.
How often should you change your toothbrush?

How to take care of your toothbrush?
If you are sharing your bathroom, make sure that your toothbrush head is not touching the other toothbrush head.
After brushing your teeth, rinse your toothbrush with tap water and place it in an upright position and let it air dry.

When traveling, be sure to cover your toothbrush head to protect it and reduce the spread of germs.
You could also store your toothbrush in a small cup of hydrogen peroxide overnight. Hydrogen peroxide won't damage the bristles as easily as antibacterial mouthwash would, so overnight soaking is safe. Remove and rinse your toothbrush the next morning.
