Does my toothbrush collect bacteria?

“The short answer: yes. After brushing your teeth, your toothbrush is populated with microorganisms. Therefore, if you’re sick (flu, cold, strep throat, cough, etc.) and you don’t want to risk reinfection, clean the bristles of your toothbrush with water, as usual, and then spray the bristles with our mouth spray to disinfect them. This will give the ClO2 (chlorine dioxide) time to work before you use the brush again.” - Dr.med.dent Vaclav Velkoborsky, Zürich.
