UV hardening (composite) fillers contract by about 8%, when hardens. It creates internal stress. And that plastic can crack under load. That is one of reasons why in some countries (especially eastern european shitholes), amalgalm fillings are still popular. As they can take way more load before breaking. Well, normally.
There are also chance to use ceramic (porcelan or zirconia) "crown", which will be placed over existing teeth. But it is more expensive, and usually are done to teeth with way bigger damage. Difference is like 40 eur for amalgam, vs 600 eur zirconia "crown".
But about mercury, its vapor is most toxic. Luckily you are not breathing come fumes from broken CFL lamps. From dental fillings, there are way less. There still are, but if compare with other sources, not much.
