What is Composite Filling?

Composite filling is a restorative dental treatment used by dentists to treat cavities, fractures or other damage to teeth. Composite fillings are usually white in color and made of a material that matches the color of the teeth.

Composite fillings are commonly used to correct small to medium-sized dental problems. However, for large restorations or worn teeth, other restorative options such as metal-backed porcelain may be preferred. Your dentist can guide you in determining the best filling option for your needs.

How Is Composite Filling Done?

Composite filling application is performed by the dentist by following the following steps:

Examination and Planning: The dentist examines the decayed, fractured or damaged area and assesses the need for treatment.

A treatment plan is created and it is determined whether composite filling is a suitable option.

Anesthesia: The treatment area is numbed so that the patient does not feel pain or discomfort.

Preparation: The treatment area is prepared by removing decayed or damaged tissue.
If necessary, the dentist will remove the decayed or damaged parts.


This step ensures that the filling adheres firmly to the tooth.

Application in Layers: The composite filling is applied to the tooth in thin layers. Each layer is hardened with a light called light polymerization.

Shaping and Coloring: The dentist shapes the composite material to restore the natural form and aesthetic appearance of the tooth. Composites are produced according to the color scale. We cannot change the color of the composite during the procedure; however, we can use composites of different colors together to make them compatible with the tooth. The color of the composite to be used is determined at the beginning of the procedure.

Polymerization: After the application of each layer, the dentist hardens the filling material with a special polymerization lamp.

This step increases the durability of the composite filling.

Shaping and Polishing: After the application is complete, the dentist shapes and polishes the filling material for the final time.

This step ensures that the filling has a smooth and shiny surface that is compatible with the tooth.

Checking and Adjustments: The dentist checks the fit of the filling to the tooth and makes fine adjustments if necessary. The composite filling can usually be completed in a single visit, allowing the patient to return to normal daily activities immediately. Your dentist will customize the process depending on the specifics of your dental problem and your treatment needs.

What are the Advantages of Composite Filling Treatment?

Composite filling treatment has many advantages that make this restorative dental treatment popular. Here are the main advantages of composite filling treatment:

Aesthetic Appearance: Composite filling material offers a choice of shades that match the color of the teeth. This provides a natural look when the filling is applied and can be used comfortably on the front teeth.

Tissue Preservation: Composite filling can be used to treat decayed or damaged parts of the tooth while preserving the healthy parts of the tooth. This helps to preserve the natural structure of the tooth.

Less Loss of Tooth Material: Dentists can ensure that less tooth material is removed in a composite filling. This allows for a less invasive treatment than traditional filling materials.

Reducing Sensitivity:

Ease of Filler Renewal: Composite fillers can be more easily machined to repair or replace a damaged filler material. This simplifies filler refill or replacement operations.

Instant Hardening: The composite filling material can harden immediately thanks to light polymerization. This allows the dentist to complete the treatment in the same session and the patient to immediately return to normal daily activities.

Metal Free:

Can be used in different places: Composite fillings can be used in many different situations, from aesthetic improvements in the front teeth to caries repairs in the back teeth.

Ease of Use: Dentists can apply and shape the composite filling material directly to the tooth. This allows for a fast and effective treatment process.

These advantages make composite filling treatment comparable to other restorative options. However, the treatment plan is customized for each patient, so it is important to consider the recommendations of your dentist.

What are the Disadvantages of Composites?

Although composite fillings have many advantages, they also have some disadvantages. Here are some disadvantages of composite filling treatment:

Durability: Composite fillings may be less durable than some restorations, such as metal-backed porcelain. They may need to be replaced more frequently, especially when used in large restorations or in posterior teeth subjected to high chewing forces.

Color Changes:

Price: Composite filling treatment can be more expensive than some other restorative options. The cost can increase, especially for large restorations.

Sensitivity: Some patients may experience temporary sensitivity when composite fillings come into contact with hot or cold foods and drinks. This usually subsides over time.

Single Session Procedure:

Lack of Architectural Stability: In large restorations, composite filling may have some limitations in terms of architectural stability (long-term stability).

Disadvantages may vary depending on personal preferences, treatment needs and the dentist's recommendations. When creating a dental treatment plan, the patient's specific situation should be taken into account and the advantages and disadvantages should be balanced.

In Which Situations Can Composite Filling Be Considered?

Composite fillings can be used to treat a variety of dental problems. These conditions can include:

Cavity Repairs:

Repairing Fractured or Cracked Teeth: Small fractures or cracks in teeth can be repaired with composite fillings. This is used to preserve the structure of the tooth and improve the aesthetic appearance.

Teeth Reshaping and Color Correction: Composite fillings can be used to correct tooth shape or color inconsistencies. These fillings can be preferred to make teeth more attractive for aesthetic reasons.

Closure of Tooth Gaps: Composite fillings can be used to aesthetically close tooth gaps. It can be preferred especially to close small gaps in the front teeth.

Replacement of Old Fillings:

Bridge Connections for Missing Teeth: In the case of missing teeth, bridge connections made with composite fillings can be used. This can be an option to compensate for missing teeth and provide a natural look.

Minor Restorations without Damaging the Tooth Surface: Composite fillings can be preferred for small tooth restorations or aesthetic improvements without damaging the tooth surface.

Removal of Tooth Sensitivity: Composite fillings can be applied to exposed sensitive areas of the tooth to remove tooth sensitivity.

Composite fillings offer a wide range of applications to meet aesthetic expectations and preserve the natural structure of the tooth. However, it is important to consult a dentist to determine the most appropriate treatment option in each case.

Composite Filler Color Variety

Composite fillings come in a wide variety of colors, and dentists can use different shades to best match the color of patients' teeth. The choice of color is an important factor affecting the aesthetic success of the treatment. Here is information about composite filling color variations:

Tooth Color Matching: One of the main advantages of composite fillings is that they offer shade options that match the color of the teeth. Dentists can choose from a range of shades to accurately match the patient's tooth color.

Color Charts:

Color Blending Ability: Dentists can create a custom blend by combining various shades of color together. This is used to best mimic the natural color of the tooth.

Esthetic Evaluation: Dentists carefully evaluate the patient's tooth color before applying composite fillings. Choosing the right color increases the aesthetic success of the treatment.

Transparency and Opacity Control: During color selection, dentists can control the degree of transparency or opacity of the composite filling. This can help to further harmonize with the appearance of the natural tooth.

Lighting Conditions: Dentists evaluate tooth color under different lighting conditions. Evaluations under different lighting can help them better understand how the composite filling will look in different environments.

Correctly matching the patient's tooth color not only increases the aesthetic success of the composite filling application, but also increases the patient's satisfaction. Dentists are experienced in color selection and determine the most appropriate shade by taking into account the wishes of the patients.
