Comparing Different Types of Cavity Fillings

If you or your child has a cavity, you may be wondering about the process for removing and filling that cavity. Over the years, dentists have used a number of different materials to fill their patients’ teeth after cavity removal, some of which have evolved and become preferred, while others are no longer used at all. Our Spring Branch dentist offers three common types of cavity fillings, which we’ll discuss here.

What Are Cavities?

Cavities are damaged parts of the tooth caused by a combination of bacteria, excessive sugar consumption, and ineffective hygiene. Our Spring Branch dentist must remove the cavity or else it will become larger, requiring more invasive treatment, like a root canal or dental crown, to address it. The best way to prevent cavities is to enjoy sugary drinks and snacks in moderation, maintain effective brushing and flossing habits, and visit with our Spring Branch family dentist regularly. Kids are more prone to cavities, which is why our Spring Branch pediatric dentist stresses the importance of establishing oral hygiene routines at an early age.

Cavity Fillings With Our Spring Branch Family Dentist 

Our Spring Branch dentist fills cavities in our modern, comfortable office using a simple procedure. First, a numbing medicine is applied to the tooth and gums, then our Houston family dentist removes the decay with a small drill. Once the decay has been removed completely, the tooth will be sealed using one of the following materials:


Amalgam fillings have been used for over a century and are composed of a variety of metals, including mercury. Because they are inexpensive and durable, it remains a popular choice for fillings, though its mercury content is of concern to some patients. Furthermore, the metallic color of amalgam fillings does not match the tooth’s color. For that reason, they are typically used on back teeth only. 


Porcelain fillings are a strong and durable dental filling that matches the tooth’s color, making them an ideal choice for cavity fillings needed on teeth that sit near the front of the mouth. They are also free from metal and resistant to stains. 

Composite Resin

The most popular choice, a composite resin filling is composed of quartz or glass and resin. They are a safe alternative to amalgam and can be matched to any tooth shade. They last between 5-7 years, at which point they’ll need to be replaced.
