Solid-head power toothbrushes may be the best choice, according to a recent study.
The University of Texas Health Science Center at Houston School of Dentistry recently did a study on toothbrushes that confirmed a suspicion we have had for some time in dentistry. The study was published in the Journal of Dental Hygiene and stated that the hollow areas of a toothbrush can collect a variety of bacteria which lead to an increased exposure to the mouth over time. 90% of the tests done showed that the microbial counts were lower in a solid-head group when compared to a hollow-head toothbrush. This study confirms why we give solid head toothbrushes when you come in for a cleaning.
