3 years with Emax veneers - what could be the reason for black staining? (photo)

Question

I had Emax veneers for both of my top front tooth before 3 years, but in the last few months i noticed a very small black line on one of my veneers that was root canal treated. What could be the reason for this?

Thank you for your question. A small black line on a veneer can have different causes, depending on the condition of the underlying tooth, and the quality of the bonding. One possible cause is that the veneer is slightly chipped or cracked, exposing the darkened tooth underneath. Another possible cause is that the root canal treated tooth has changed color over time, and the veneer is no longer covering it. A third possible cause is that there is some staining or leakage at the margin of the veneer, where it meets the tooth. To determine the exact cause and the best solution, you would need to visit your dentist for a clinical examination and possibly some x-rays. Depending on the situation, you may need to replace the veneer, whiten the tooth, or improve the bonding. I hope this helps you understand your situation better and gives you some guidance on what to do next.

The adhesive material (resin cement) which bonds your teeth and Emax veneer may be discolorated. Those materials are chosen as the same color with tooth but in passing time, the exposed portion may absorb oral liquids and undergo discoloration.It can be removed by dental intervention like polishing.
