Bonded Front teeth / Black lines: The top and sides of my direct bonded teeth (front four) are starting to turn black after five years.
Can you tell me what has happened? ...Visitor from GA
Composite restorations, unlike their porcealin veneer counterparts, can discolor and stain over time. Usually with 3-5 years, depending on the material selected.
With the nano-hybrid type of composites used today by most dentists, the composites still look good after 6-7 years.
It appears from what you are saying there is leakage under your restorations. In other words the
seal has been broken and there is bacteria accumulating under the restorations.
