At some point in our lives, most of us will need to have to have a filling. But regular fillings come with many disadvantages. One of the biggest issues is how they can affect our smile. Big, metallic fillings hardly add to our aesthetics.
But now there’s a new kid on the block that promises to change all that: composite fillings. Composite fillings are a mixture of plastic and glass. And, right now, they’re proving to be very popular. Here’s why.
They Look Good
One of the biggest problems with regular, metallic fillings is their silvery colour. Having many large, amalgam fillings can make you feel like your natural smile has been ruined. It’s depressing.
Composite fillings, on the other hand, don’t stand out like regular fillings. They can be coloured to match the colour of your teeth. And that means that you don’t have to worry about baring all when you laugh and smile.
They Are Versatile
The great thing about composites is that they can be repurposed for practically any purpose. Composites can be used to reshape damaged teeth and even change their colour. They’re particularly useful for people who have had teeth chipped in accidents.
They Offer Great Support
When you have a filling, the filling itself needs to be able to bond with the tooth. Old-fashioned amalgam fillings did bind, but often not very well. Composite fillings tend to bind a lot better, strengthening teeth that have suffered decay.
Composite fillings also require less of the tooth itself to be removed than amalgam fillings. One of the problems with amalgam fillings is that they needed a bigger hole to make them bind. But composites don’t. And that means you get to preserve more of your natural tooth enamel.
They Are Better At Comping With Heat
One of the major flaws in amalgam fillings is their response to changes in temperature. Like any other metal, they expand when they get hot and contract when they get cold. Of course, when people eat hot food, like soup, the temperature in the mouth goes up. When they eat cold food, like ice cream, the temperature goes down. It’s this variation in temperature that causes teeth to crack.
The good news is that composite fillings don’t behave the same way as amalgam fillings. Unlike metal fillings, composites are natural insulators. So even when the temperature in your mouth rises, they don’t get as warm.
They Are Durable
Historically, one of the reasons composites didn’t take off was because they weren’t seen as durable. And in truth, they weren’t. For instance, composites were not used for back teeth in the past because of the high shearing and grinding forces. But since then, the durability of composites has improved significantly. Material science breakthroughs have allowed composite fillings to get much stronger.
Composite fillings, therefore, are now a viable option for most patients. They offer many advantages over traditional amalgam fillings, with few of the drawbacks. With composite fillings, there’s no reason to hide your smile.
