Because It Looks Like a Tooth

If we were to ask you why a tooth-colored filling is nice to have, you might say something like “because it looks like a tooth.” This is true, and it is one of the primary reasons why patients appreciate this filling. The availability of a filling that looks like a tooth demonstrates how far we have come since the early days of formal dentistry.

The first fillings to be used were made of gold. Nice! In fact, gold was a very nice option because this metal was one of the only that was capable of a long-lasting fit in dental enamel. The problem was, gold was expensive. As an alternative, dental amalgam was developed. This type of filling was called a “silver filling” then and still is today. But it’s not just silver that is in an amalgam; there is also copper, tin, and elemental mercury. Remember how we said that gold fillings were valuable because they could fit will in enamel? Amalgam isn’t quite as good at this.

When metal gets hot, it naturally swells. When we chew, friction is created between teeth, so, where there are fillings, they will get hot. If the filling is made of amalgam, it will also swell. This isn’t good for the long-term health of the tooth. Metal that swells when hot then shrinks when it is cooled. This is the problem with dental amalgam. A filling needs to maintain tight margins to keep bacteria out. The frequent swelling and shrinking of amalgam can degrade margins, making the tooth vulnerable to further decay.

Tooth-colored fillings look good; that’s true. They also restore a high degree of strength to teeth because they can be bonded to enamel and because their margins remain intact even when heating and cooling occurs.
