Hidden Germs at the Dentist's Office
The clips that hold dental bibs may also be holding bacteria.
Researchers tested the clips at a dental clinic after they had been disinfected.
They found as many as 70-percent were carrying some type of bacteria.
The germs can be transferred from a previous patient or from the hands of the dental workers.
Researchers suggest dental offices either thoroughly sterilize the bib holders or start using a disposable version.
