Composite Tooth Bonding FAQ Ara Nazarian Question:
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

Answer:
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.
