Worn Out

Does Your Toothbrush Look Like This?

Brushing regularly will help you maintain a healthy smile. However, if you're not changing your toothbrush or electric toothbrush head regularly, you may not be as effective as you think.

When toothbrush bristles become flared or tilted, they tend to loose their ability to clear food and debris from the nooks and crannies of your teeth.

The ADA recommends we replace our toothbrushes approximately every 3–4 months, or sooner if the bristles become frayed with use.

The ADA's Council on Scientific Affairs, in November 2011 stated the following:

(Warning: Scientific Content)

"In recent years, scientists have studied whether toothbrushes may harbor microorganisms that could cause oral and/or systemic infection. We know that the oral cavity is home to hundreds of different types of microorganisms; therefore, it is not surprising that some of these microorganisms are transferred to a toothbrush during use. It may also be possible for microorganisms that are present in the environment where the toothbrush is stored to establish themselves on the brush.

Although studies have shown that various microorganisms can grow on toothbrushes after use, and other studies have examined various methods to reduce the level of these bacteria, there is insufficient clinical evidence to support that bacterial growth on toothbrushes will lead to specific adverse oral or systemic health effects."

Here are some "common sense" tips for caring for your toothbrush (as recommended by the ADA):

Do not share toothbrushes. Sharing a toothbrush could result in an exchange of germs between the users. This practice could be a particular concern for persons with compromised immune systems or existing infectious diseases.

Thoroughly rinse toothbrushes with tap water after brushing to remove any remaining toothpaste and debris. Store the brush in an upright position if possible and allow the toothbrush to air-dry until used again.

Do not routinely cover toothbrushes or store them in closed containers. A moist environment such as a closed container is more conducive to the growth of bugs than the open air.

Replace toothbrushes at least every 3–4 months. Toothbrushes will wear out more rapidly depending on factors unique to each patient. Check brushes often for this type of wear and replace them more frequently if needed.
