Advances have been made in modern dentistry, and the good news is that now white fillings are beautiful, strong and long-lasting. They are a dense pressure treated restoration. The color is invisible and it blends into your surrounding tooth.
The chart below shows a comparison of silver Amalgam fillings to White Fillings and Bonding
Silver Fillings
Black Color
Requires removal of decay and part of the good tooth substance to create enough room for the silver, because it has to be bulky to be strong.
Weakens the tooth
Concerns about Toxicity of mercury in silver filling.
Possible recurrent decay around corroded, rusted margins of silver fillings.
If filling cracks or chips, usually the whole filling has to be drilled out and replaced.
Unattractive.
White Fillings
Natural White Color
Requires removal of decay only. Because filling bonds to the tooth, it preserves tooth substance.
Strengthens the tooth because it bonds to the tooth. That tooth becomes one solid mass again like before it was decayed.
No Mercury
Filling material bonds to the tooth margins. It is sealed and does not rust.
Can easily be repaired by adding on to the bonding.
