Dental filling procedures are most commonly used to treat cavities, but they’re also used to repair cracked or broken teeth, or teeth that have been worn down over time.
Amalgam Fillings
Amalgam fillings are what you might think of as “silver” dental fillings, though they’re actually composed of a mixture of copper, tin, mercury and silver. The reason dentists have been using them for so long is that that they are strong and long-lasting. However, they’re very noticeable and tend to darken over time, so if you want something that blends in, amalgam fillings probably aren’t the ones you want.
Gold Fillings
Gold fillings aren’t made of pure gold just like amalgam fillings aren’t made of pure silver, but they are some of the most durable fillings available, capable of lasting more than two decades. They can’t corrode like amalgam fillings, and they are very strong.
Glass Ionomer Fillings
These types of fillings are made of acrylic and flour aluminosilicate, a component of glass. They are typically used as cement for inlay fillings in the front teeth, and for fillings when the decay extends into the root of the tooth.
Composite Fillings
Once a dental implant has integrated into the jaw bone, studies have shown a survival rate in excess of 90% after 15 years. However, studies have also shown that this is reliant on a high standard of dental hygiene, regular observation and maintenance with a dental professional.
Ceramic Fillings
Ceramic fillings are made of porcelain. This makes them another low-profile option, and not only are they tooth-coloured, they’re also stain resistant.
