no ....... amalgam tatoo is not chemically unstable .
silver amalgam is dental restoration in which there are 2 major
components .
1st :- silver alloy which contains silver , cupper , zinc .
2nd :- mercury .
these 2 components have to be mixed togather to make a workable
mix .
amalgam tattoo is caused by leaching of mercury from the
restoration .
though mercury is harmful for th body , but the amount of
mercury is negligeable to cause any reaction .
so dont worry .
