Toothbrushes are meant to be replaced at least every three months. However, it is also ideal that you replace your toothbrush after recovering from a cold, or flu. Old toothbrushes can be kept for art projects and as an all-around cleaning tool in the house. Here are a few suggestions on how to take care of your toothbrush:

Toothbrushes can be very effective breeding grounds for bacteria. Always rinse your toothbrush well every time you brush. What you do is wiggle the bristles underwater. Check to make sure that all food and other debris are removed.

Keep your toothbrush in an upright position with the bristles up. Place it in a holder or a cup. This will completely dry the bristles. But don’t have a communal toothbrush cup. This will help spread germs. Don’t forget to wash the toothbrush container regularly.

Never let anyone use your toothbrush. It’s not only unhygienic, but it will also shorten the lifespan of your toothbrush. Buy extra toothbrushes for guests and for emergency reasons (like accidentally dropping it into the toilet)

Buy a toothbrush protector for your toothbrush when you are traveling. This will make it sure it does not come in contact with the other stuff in your luggage.

Sterilize your toothbrush once a week using an automatic dishwasher. Just be careful not to melt the plastic handle.

If your toothbrush looks all worn down, buy a new one.
