There is a Dark Line Between the Edge of the Tooth Filling and my Natual Tooth, Should I Be Concerned? (photo)

The dark line is probably caused by an inefficient seal between the tooth and the filling.  This can lead to decay underneath the filling in the future, so I would have it replaced.

 

Good Luck!

Yes. That line might be the result of microleakage that could be the result of an incorrect light curing technique or bulk filling. Have your dentist check it before it leads to secondary decay beneath your restoration. Always check margin adaptation of restorations.

I would suggest to have consultation with your dentist and redo the filling. It can be cause of problem in future.

Yes you should be concerned. It looks like the bond between the edge of the filling and your enamel is failing. This could possibly lead to future decay. Have your dentist check it and correct it.

There appears to be a stain at the filling - tooth interface not a new cavity. Several small factors could contribute including shrinkage of the material or excess material  coming off. Not a large matter of concern.

Have your dentist evaluate it for definitive diagnosis and recommendations.

resins in posterior teeth, are not a good idea, if there are big restorations, overlays,onlays, in ceramical, are intended for these cases, the bite its very strong here, and this can cause the resin to have this type of issues,i will re-do it,

The discolored margin is due to leakage.  Your dentist can repair just that portion..........................
