(HealthDayNews) -- Take a photograph to the lab, and you expect each copy to be as good as the first. But if you send your false teeth to the dental lab, put your expectations in low gear, says the British Journal of Dentistry.
When the same set of dentures was sent to 12 different labs for copying, none did a perfect job, and only five made a copy rated "good."
In addition, the original dentures had a diastema -- a David-Letterman space between the front teeth. For some reason, eight labs filled the space.
