What is the difference between silver and tooth coloured fillings?
Besides cosmetic differences, there are several. What has been noticed is that due to the expansion of silver filling materials and because silver fillings are wedged inside of a tooth for retention, stress can occur to your natural enamel. This often leads to a premature fracture of your tooth, which might necessitate a crown. With properly placed tooth colored filling, your tooth is actually strengthened by filling not weakened, because it is bonded (connected) to the tooth, not wedged in.
