What are the advantages of silver fillings?

They last longer and live longer; it is reported that an amalgam filling can last an average of 10 to 15 years, and the average duration of composite filling is 3 to 10 years;
Their cost is lower: less steps are required to prepare silver fillers, making them less costly;
They can lead to decreased sensitivity after surgery: After the teeth are filled with white, the teeth may be sensitive for weeks, sometimes months, after the teeth are reserved; the gray filler is less sensitive to teeth after being placed.
