One thing you might not have considered is how the head of your toothbrush could be affecting your ability to protect your teeth from bacteria. In fact, recent research has found that not all power toothbrush heads are created equally.

Study Examines Toothbrush Heads

The University of Texas Health Science Center in Houston recently studied the bacterial resistance of certain power toothbrush heads. They found that solid-head toothbrushes retain less bacteria when compared to power toothbrushes with hollow heads.

In fact, the bacteria counts were lower in a solid-head toothbrush, then in groups of hollow-head toothbrushes in 9 of 10 comparisons. These results were published in a recent edition of the Journal of Dental Hygiene.

The study took place over a three-week period, and participants brushed two times per day with one out of three randomly assigned electronic toothbrushes. All participants used the same toothpaste and flossed as normal, but none of them took advantage of other practices or used other products like mouthwash.

During the study, the brush heads on the power toothbrushes were exposed to five different types of oral microorganisms, and the end result was that the hollow-head brushes had bacterial growth that was 3,000 times greater than that found in the other varieties.

Is This Increase in Bacteria a Problem?

According to the study authors, there is no data available that demonstrates that this increased bacterial growth might result in greater health effects. However, several microorganisms have been linked to systemic diseases.

For example, Fusobacterium species of bacteria have been linked to colorectal cancer, while some of the other options have been connected to heart disease. In order to minimize your chance of encountering these bacteria in large numbers, you should be sure to invest in the proper brush head.
