When and Why Should We Change Our toothbrush?


Sometimes the frequent use of a toothbrush makes you forget that it’s high time to replace them. Instead of waiting for the bristles of your toothbrush to wear out entirely, it’s highly recommended to change yours every three to four months!

Toothbrushes can become contaminated with oral microbial organisms whenever they are placed in the mouth. Different kinds of viruses and bacteria from an infected person’s mouth can also live for weeks on a toothbrush surface and continue to cause illness. Worryingly, even normal, healthy microorganisms can cause infections, especially if they enter your gum tissue due to an injury, a break, or an oral ulcer.

One important rule is to never share toothbrushes, even with your family or significant other. Sharing a toothbrush could result in an exchange of body fluids and/or microorganisms between the users of the toothbrush, placing the individuals involved at an increased risk for infections. Doing this can be potentially harmful for people with compromised immune systems or existing infectious diseases.

Another is to thoroughly rinse toothbrushes with tap water after brushing to remove any remaining toothpaste and debris. Store the brush in an upright position after if possible and allow the toothbrush to air-dry until used again. If more than one brush is stored in the same holder or area, keep the brushes separated to prevent cross-contamination.

Lastly, try not to cover toothbrushes or store them in closed containers. A moist environment such as a closed container is more conducive to the growth of microorganisms than the open air.
