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

Question

I had this tooth filling done 4 months ago. Yesterday I saw a dark line between the edge of the filling and my tooth. I brushed it with toothbrush but it didn't come off. It doesn't hurt, could it be cavity since it's only been a few months? That part was healthy before the filling. What could be causing the dark line? Should I have the dentist remove the filling and redo it, or just remove that dark line part and add some filling on top? I'm attaching pics of 4 months ago and today. Thanks.

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.

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.

Jay Neuhaus, DDS · Answer

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.

Michael Dorociak, DDS · Answer

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.
