Is there a definitive way to determine if crown fits properly?

I recently had all porcelain dental crowns installed on my four front teeth. When I floss two of them at the gumline, I can taste and smell a foul bacterial scent on the floss.

The dentist poked around with a dental instrument and says they fit properly, but I disagree. None of my other teeth (crowned or real) produce the odor, so something isn't right. He told me x-rays won't necessarily show whether or not they fit, so is there a definitive way (i.e., special type of x-ray, MRI, etc.) to determine if the fit is correct?

But you can always use x-ray as a help to determine if there is any gap.Tthe odor might be coming from uncleaned cement left after the veneers or crowns were cemented. Ask your... more

A: There are several ways to determine if crown fits properly

Anca Bazile, DDS

First, the crown has to fit perfectly over the tooth so that its margins meet the margins of the tooth preparation. Once the crown is "down" on the tooth, the contacts between the adjacent teeth should be adequate: floss should snap on either sides without breaking and without just sliding through. A... more
