Did you know solid-head power toothbrushes are better hygiene-wise compared to the hollow-head ones? According to researchers from University of Texas Health Science Center at Houston, School of Dentistry, hollow-head power toothbrushes retain more bacteria. In nine out of ten comparisons, microbial counts in solid-head power toothbrushes were lower than the hollow-heads, lead research author Prof. Donna Warren Morris, R.D.H., M.Ed., revealed. ?Toothbrushes can transmit microorganisms that cause disease and infections,? Prof. Morris said. ?[But] a solid-head design allows for less growth of bacteria.? She added that the bristles should be soft and nylon-made.
