Compared to other cosmetic treatments, porcelain veneers are durable and long-lasting. However, veneers are not indestructible and may not last forever. Individual differences such as your diet, habits, and bite will affect the durability of the veneers and may eventually need to be replaced.
Thanks for your inquiry. Modern bonding materials (composite resins) will typically show up on X-rays (they appear whitish/greyish). If the filling material used was older, it will typically appear darker on the X-ray (dark grey or black). Either way, if the bonding is very small or thin, it may be more difficult to identify on an X-ray. The doctor's notes and written records from the office should indicate what exactly was done, so that may provide a better answer than the X-rays. Also, if the dentist looks at the teeth carefully, they should be able to tell. Sometimes it's difficult, especially with modern materials that are very life-like. However, drying the teeth thoroughly and providing good lighting will often help dentists identify natural tooth structure from bonding material.
