I could use guidance. My toothbrush holder tipped over and the brush bristles and paste touched the countertop. I know that it gets cleaned with the sink and that there have been other toothbrushes on the counter as well as meat pieces (unkosher because it’s a shared sink) in sink from spitting after brushing. Is it ok to use the toothbrush or is there concern that it could have meat on it now (and then to use after dairy) or unkosher food?
To put it simply, would meat or unkosher transfer to the counter and then to the toothbrush?
There is no need for you to be concerned that there might be something on the toothbrush, unless you know that it touched meat.
