Composite Fillings

What Are Composite Fillings?

Most of us are familiar with fillings. According to the CDC, approximately 91 percent of U.S. adults between the ages of 20 and 64 have at least one filling. By the time the age increases to 65, the number is 96 percent. 

OK, so just about everyone has at least one filling. The vast majority of those fillings are silver amalgam, which was the filling material of choice starting in around 1850 until recently when it was replaced with composite resin. 

Composite resin was first introduced for fillings in the 1960s. Also known as “tooth-colored fillings,” composite resin blends in perfectly with the surrounding natural tooth enamel. The problem with composite was that the early forms tended to break down more quickly than amalgam, so they weren’t as durable. But in the 1990s and 2000s, the resin was mixed with glass ionomer, which greatly increased the strength and durability of composite resin fillings.

Candidates for Tooth Fillings

Dr. Holbrook uses composite resin for both new fillings and for the replacement of old silver amalgam fillings. Of course, if you come to see us for your regular twice-yearly cleaning and exam and we discover you have a tooth with decay, you won’t necessarily plan to have a new filling, but more and more we are using composite resin for these fillings. 

Also, we have many patients who either want to replace old amalgam fillings for aesthetic reasons or they need to replace them as the filling or fillings are reaching their lifespan. Most people no longer like the idea of having mercury in their teeth, and they’d rather have composite resin. 

There are no restrictions for whether or not a person can have composite fillings placed. 

What Are The Types of Dental Fillings?

You and Dr. Holbrook can discuss the best options for restoring your teeth. Composite fillings are the most widely used filling material today.  Because composite fillings are tooth-colored, they can be closely matched to the color of existing teeth, and are more aesthetically suited for use in front teeth or the more visible areas of the teeth.

Benefits Of Tooth-Colored Fillings

The most obvious benefit is appearance. When Dr. Holbrook places a composite resin filling in a tooth, you’re going to be the only one who knows that tooth has a filling. They are basically invisible to anyone else looking at your smile. Beyond appearance, unlike amalgam fillings, composite fillings actually bond to the tooth surface, making the tooth stronger. Plus, when placing an amalgam filling, more of the healthy tooth structure needs to be removed to create room for the filling. Because composite resin bonds to the tooth, it is not necessary to remove the same amount of healthy tooth material. 

Composite Filling Procedure

Composite fillings are usually placed in one appointment.
  • While the tooth is numb, your dentist will remove decay as necessary.  Space will then be thoroughly cleaned and carefully prepared before the new filling is placed.
  • If the decay was near the nerve of the tooth, a special medication will be applied for added protection.
  • The composite filling will then be precisely placed, shaped, and polished, restoring your tooth to its original shape and function.

It is normal to experience sensitivity to hot and cold when composite fillings are first placed, however, this will subside shortly after your tooth acclimates to the new filling.

How long does it take to place a composite filling?

These fillings take no longer than placing a silver amalgam filling. These are done in a single appointment. Usually what happens is that we find the decay during your exam and we opt to immediately remove it and place the composite resin filling. Small fillings may take as little as 20 minutes. Larger fillings, where we need to remove more decay, may take up to an hour.

How Do I Care For My Tooth-Colored Fillings?Tooth Colored Filings Albuquerque, NM

You will be given care instructions at the conclusion of your treatment. Good oral hygiene practices, eating habits, and regular dental visits will aid in the life of your new fillings.

As with most dental restorations, composite fillings are not permanent and may someday have to be replaced. They are very durable and will last many years, giving you a long-lasting, beautiful smile.

How long do composite fillings last?

Up until the last decade, composite resins used for fillings were not as durable as silver amalgam. That’s why many practices resisted using resin, except for small fillings on non-molars. That has changed. Thanks to various technological advances, the strength and durability of composite resin fillings are roughly equivalent to that of silver amalgam. The average lifespan for these fillings (and for amalgam) is about 12 years. This lifespan can be far longer; it depends on the patient. 

Are there any risks with composite resin fillings?

These are virtually risk-free treatments. When Dr. Holbrook places a filling, the decay has not entered the interior of the tooth, so it has not come in contact with nerves or blood vessels. That makes for virtually no chance of infection. Composite resin is safe and actually strengthens the tooth. 

In contrast, placing silver amalgam fillings does involve some risk. Silver amalgam fillings involve the risks of cracking a tooth, allowing decay to form around the filling, and they require more tooth to be removed. And, of course, you are putting mercury in your mouth. 

Are dental fillings covered by insurance?

Yes, because removing tooth decay and placing a filling prevents further damage to a tooth, dental insurance covers these procedures. 

Do tooth-colored fillings cost more?

Because composite resin costs more than silver amalgam, tooth-colored fillings cost from 10 to 20 percent more than amalgam. Dr. Holbrook believes the minor variation in cost, however, is more than made up for by the advantages of these basically invisible, beautiful tooth restorations.
