How Do Tooth Colored Fillings Work?

Tooth-colored fillings can restore the functionality of a child’s teeth while creating an aesthetically pleasing smile that leaves them happy with the dental work received. Composite fillings, in particular, are becoming increasingly common. Therefore, it is important for patients to know whether the option may be right for them.

What are tooth-colored fillings?

Composite resin fillings are the technical name for fillings that are the same color as a patient's natural teeth. They can fill in small- to mid-size cavities and hold up well against the pressure of biting and chewing. Useful in both back and front teeth, composite fillings are common for those who want something that looks natural in the mouth.

How composite fillings work

Composite fillings, sometimes called resin-based composites, use a special glue to bond them to the child's remaining healthy teeth. Composite is also becoming increasingly popular over amalgam for filling small cavities in the teeth.

About the filling procedure for children

Composite fillings may take a bit longer to place, but overall, the procedure for receiving them is very similar to receiving other types of fillings. Before cleaning, the pediatric dentist looks at the child's natural teeth to determine the right color match for the composite filling. Then, the cleaning process can begin. In order to ensure effective bonding, the dentist may need to trim the natural tooth, though it is not always necessary. The trimming creates a strong base. The dentist will determine how much they need to trim by how much decay is present.

After the pediatric dentist prepares the natural tooth, they will use a special dental conditioner to complete the etching process. This process also ensures that the surface of the tooth is able to bond well to the composite filling. Once applied, the bonding agent must harden to create a seal for completing the filling. After the initial bonding is complete, the dentist will add the composite in small layers, which helps maintain a natural shape for the tooth. To finish, they will use a special light to cure the material between the application of each layer.

Children can expect their mouths to be numb for a few hours after the procedure and may find it difficult to taste drinks or foods. This is normal; however, if children complain to their parents about these side effects lasting into the next day, contact our office so that we may advise.

Advantages and disadvantages of composite fillings

Like any dental procedure, composite resin fillings have advantages and disadvantages. On the plus side, composite fillings are durable and bond well to the natural tooth. In addition, because the dentist applies the material in layers, the results look more natural, match the other teeth more precisely, and provide an aesthetically pleasing look many children proudly show off.

On the downside, composite fillings are unsuitable for people with extensive tooth decay. Typically, they do not last as long as metal fillings. They also tend to be more expensive than metal fillings due to their cosmetic nature.
