A standard toothbrush holder keeps a toothbrush upright, with the head facing toward the ceiling. If you don’t use a toothbrush holder, you might keep your toothbrush face down on the counter or covered with a case. With all the various ways to store a toothbrush, which is the right way?
According to the American Dental Association (ADA), your toothbrush should be stored upright in order for it to air-dry until it needs to be used again. “If more than one brush is stored in the same holder or area, keep the brushes separated to prevent cross-contamination,” suggests the ADA.
The ADA also doesn’t recommend routinely covering toothbrushes or storing them in closed containers. A moist environment is the ideal breeding ground for bacteria.
So there you have it!
