Decay under composite temporary veneers? (Photo)

Temporary veneers don't bond well to the teeth because they are designed to come off easily. This can allow bacteria to collect under the temporaries. When your permanent veneers are placed, the area will be cleaned and disinfected. Decay is a much slower process.  I hope this helps. Follow me for more questions and answers.

This is common and truly a non issue.  Merely swiping hydrogen peroxide makes it disappear almost instantly and also disinfects the teeth.  Decay is a MUCH slower process, so unless decay was present and left behind, there is no problem here at all.  Hydrogen peroxide will fix nearly anything underneath the temps.You have chromogenic bacteria that got underneath and died.  Sometimes there is a smell, but not always.  I see this routinely and nothing comes of it.
