Is There a Downside to Getting Composite Fillings?


Posted on 4/20/2017 by Dr. Smith

Nowadays, you have options when it comes to fillings for your cavities. It used to be that amalgam, or silver, fillings were the most popular choice. They are strong and inexpensive.

Now, however, the popular option is composite resin. Composite fillings offer numerous benefits over amalgam. But they also have a few drawbacks as well.

Composite Resin Fillings


Composite resin fillings are made up of a mixture of plastic and fine glass in a resin material. This material is not only used for fillings, it is also used to make cosmetic fixes for minor imperfections, such as cracks, chips and gaps.

After your dentist numbs the area around your tooth, decay is drilled away and the cavity disinfected. The material is packed inside and hardened with a blue light. Once dried, it is smoothed and polished.

Benefits of Composite Resin


There are a number of benefits of composite resin for fillings:

•  It perfectly matches your tooth, so no one notice it.
•  Less drilling is required.
•  No metal, so it is a perfect alternative to those with metal allergies.
•  It bonds to the tooth, preventing breakage.
•  It can be repaired if damaged.

Disadvantages of Composite Resin


Composite resin fillings are not perfect, and do have a few disadvantages as well:

•  More labor intensive for your dentist.
•  You may have some sensitivity after getting your filling, although this is only temporary.
•  They are more susceptible to damage than amalgam, especially for teeth in the back of the mouth where there is more pressure.
•  They can be stained.
•  They are more expensive.
•  Your insurance may not cover them, as composite resin is often seen as a cosmetic fix.

Should You Get Composite Fillings?


Ultimately the decision between composite resin and amalgam is up to you and your dentist. It is important that you discuss the pros and cons of each in order to provide your mouth with the best possible results.
