I have five molars with silver fillings. Whether my dentist says I have a big cavity or a small one, he always ends up filling the whole chewing surface of my tooth with ugly silver amalgam. Why should all of the fillings have to be so big?
Why do all of my silver fillings cover the WHOLE chewing surface the tooth?
Amalgam needs to be a certain size and thickness to have enough strength to say together. It is about 1.5mms. Anything beyond this size and thickness I hope is because of decay. If the decay is confined to the groove of your molar, the filling shouldn't be too large. If the decay involves more of the tooth, then the filling will be bigger.
Reply:Some doctors would do it that way to prevent any damage to the crown of the teeth. The tooth surface around the drilling area is thinner than before and can get damage. The extra material is used to protect the teeth.
