What Materials Can Dental Fillings Be Made Out Of?

Whenever you require a filling to stop tooth decay, you have the option of which material you would like our dentist to use. Certain options are more aesthetically appealing while some are stronger or less expensive. At Springhurst Hills Dentistry, serving Louisville, KY and the nearby region, we’d like to educate you about your options to help you make a decision.


Our dentist can fill your teeth using gold or silver. Generally, metal fillings last between 10 to 15 years before you need to replace them. However, the longevity of the filling depends on how well you take care of your teeth.

Metal fillings are more noticeable than composite resin or porcelain, but the silver ones are usually less expensive than ones that match the color of your teeth. They’re also stronger and ideal for your back teeth, which take the brunt of pressure when you’re chewing. The gold fillings are the strongest and most expensive.

Composite Resin

Our dentist can alter the color of composite resin fillings to match your natural teeth, so nobody will notice you have a filling.

However, composite resin isn’t as durable as metal. Generally, this filling material only lasts five years, or possibly longer. Typically, our dentist won’t recommend this material on your back teeth because it’s more likely to chip or crack.

The process of acquiring a composite resin filling is a bit more complicated of a process than metal. Therefore, this material tends to take more time to apply than silver or gold.

Porcelain Fillings

Porcelain fillings use a ceramic to fill your teeth. They look incredibly natural because our dentist can match the color to your natural teeth. In fact, this variety of filling tends to look the most natural.

It’s also more stain resistant than composite resin and tends to last longer. Generally, a porcelain filling lasts up to 20 years. Although porcelain isn’t as expensive as gold, it’s more expensive than composite resin.
