I agree with above, get a second opinion. I recently had an old filling in a molar cause a cracked tooth. It split the tooth right in half. Needed to have the tooth removed, damage too extensive to repair. The original filling (metal) was actually triangular in shape and apparently acted as a wedge when I bite down on something hard, causing it to split the tooth. Never heard of removing good fillings to just replace, sounds fishy.
