Yes, but age alone does not mean a filling or crown needs to be replaced. Existing restorations can often continue to function well for many years.
During your examination, Dr. Hannahan looks at the condition of the restoration as well as the tooth around it. If there are signs of decay, fracture, wear, or another problem that could affect the tooth, she will show you what she sees and discuss whether treatment is recommended. If an older restoration is still healthy and functioning well, it may simply be monitored. The ADA likewise advises that existing fillings in good condition should not be replaced merely because they are old.
