Understanding Composite Fillings
Composite fillings consist of a tooth-colored resin composed of plastic and some additives. In some cases, there are also glass particles mixed with the plastic. Although mostly used for treating cavities, a composite filling can also improve a tooth's cosmetic appearance, such as reshaping a tooth.
Other common types of fillings include gold, porcelain, and silver amalgam. Compared to composite fillings, metal fillings are significantly more visible in the mouth. While porcelain fillings are closer to the surrounding teeth in color, they can be quite costly. For many patients, composite fillings offer a balance of aesthetics, affordability, and durability.

The Benefits of Tooth Fillings
Tooth fillings occur commonly in dental practice. The average American has three dental fillings, and 25% have 11 or more. Fillings fix small areas of tooth decay and serve as a barrier between the teeth and harmful bacteria. The goal is to prevent further deterioration.
Fillings help restore the normal function and appearance of teeth. Since a composite filling is tooth-colored, it is an aesthetically pleasing option. It bonds to the tooth and supports the remaining structure. That helps prevent additional damage and sensitivity to extreme hot and cold temperatures.

Composite Filling: Things to Consider
Keep in mind a few things when considering a composite filling. Compared to their silver amalgam counterparts, composite fillings do not last quite as long in larger fillings, but they do well in smaller ones. Depending on their location, they can also be prone to chipping. However, one advantage is that tooth-colored fillings can be repaired.
Compared to other options, it does take a bit longer to have a composite filling applied. However, the time difference is minimal. The shade of this type of filling can change slightly from these certain types of drinks, such as coffee, tea, and red wine. We can put a plastic coating over the material to prevent any color changes.

When a Filling Is Necessary
Various situations may call for a filling. The most common is tooth decay. Typically, a filling is the least invasive procedure for correcting decay. People who have teeth with cracks, chips, and wear can also choose to have a filling to restore teeth. In some cases, a filling can also fill small holes formed for reasons other than tooth decay. Dentists sometimes offer procedures to correct discoloration or misshapen teeth for cosmetic-only purposes.
Patients of all ages can have situations that require a filling. However, these situations are less common for children who do not yet have their permanent teeth. According to the previously mentioned National Institute of Health survey, 85% of adults have at least one filling before 34. The probability of needing a filling can also vary significantly depending on oral hygiene practices.

Frequently Asked Questions
Q. How long does it take to place a composite filling?
A. Compared to a traditional silver filling, a composite filling takes about 10-20 minutes longer to put into place. That depends on the size and location of the filling. You should expect to be in the dental chair for at least an hour.
Q. What are the advantages of a tooth-colored filling?
A. One of the major advantages of a tooth-colored filling is its ability to be matched to the same shade as your teeth. This provides a seamless look. Similar to other types of fillings, a composite filling also protects your tooth from further decay.
Q. What material makes up a composite filling?
A. Composite fillings comprise resin material that contains no metal. Instead, it is a mixture of powdered glass, silica, or other ceramic particles and plastic compounds. That makes it a good option for people who have metal allergies or want to avoid metal fillings.
Q. How much do composite fillings cost?
A. Composite fillings, like most other fillings, are typically covered by insurance as they are considered essential restorative procedures. However, we always recommend patients contact their insurance providers to determine any out-of-pocket costs before starting any treatment. We can also discuss any payment information during your consultation.
Q. How long do composite fillings last?
A. On average, a composite filling lasts around seven years. However, newer research has shown they can last for a decade or more if the filling is smaller and good oral hygiene practices get followed. Making regular trips to the dentist will help ensure your tooth-colored filling lasts as long as possible.
