Dental fillings are one of the most commonly preferred methods for resolving issues caused by tooth decay, fractures, or aesthetic concerns with front teeth. Today, composite dental fillings, which offer both aesthetics and durability, are one of the solutions that most closely resemble natural teeth.
Unlike metal fillings, they blend seamlessly with the tooth and are ideal for those who want a natural smile, especially in visible areas such as the front teeth.
In this article, we will discuss in detail what composite fillings are, their advantages, the procedure, and what to consider after the procedure.
What Are Composite Dental Fillings?
Composite dental fillings are an aesthetically compatible filling material obtained from a mixture of durable materials such as resin and fine glass particles.
Unlike amalgam fillings, they match the natural tooth colour and provide a more aesthetically pleasing result.
Used to treat tooth decay and small fractures, composite fillings are also used as composite veneers for cosmetic shaping today.
What Are Composite Dental Filling Made Of?
Composite fillings are primarily made of two components:
Resin Matrix:
The resin matrix is a plastic-like material that forms the base of the filling. It’s usually made from a type of plastic called bisphenol A-glycidyl methacrylate (bis-GMA) or urethane dimethacrylate (UDMA).
These materials are known for their durability and strength.
Filler Particles:
To enhance the strength and mimic the natural look of a tooth, the resin matrix is mixed with finely ground glass or quartz particles. These fillers provide the composite with its tooth-like color and texture.
Common Uses For Composite Dental Filling
Composite fillings are used not only for treating decay but also for aesthetic purposes. They are most commonly used in the following situations:
- Repairing broken or cracked teeth
- Aesthetic adjustment and colour matching of front teeth
- Closing gaps between teeth
- Correcting colour mismatches on tooth surfaces
- Restoration of small cavities and damaged areas
How Long Composite Filling Last?
The lifespan of composite fillings can be extended with proper care and usage habits. Generally, with proper care and regular dental check-ups, they last between 7 and 10 years.
The Main Factors Affecting Their Lifespan
- Oral hygiene habits: Regular brushing and flossing directly affect the lifespan of fillings.
- Teeth grinding and clenching (bruxism): High pressure can cause the filling to wear out prematurely.
- Breaking hard foods with teeth: Nuts or hard sweets can damage fillings.
- Consumption of sugary and acidic foods: Increases the risk of staining and wear on the filling surface.
Regular dental check-ups enable the early detection of possible cracks or wear and help ensure that fillings remain both aesthetically pleasing and functional for a long time.
Advantages of Composite Filling
- Aesthetic appearance: They provide a natural and aesthetic appearance as they match the colour of the teeth.
- Preserves tooth structure: Minimal cutting of the tooth is required, which helps preserve the natural tooth structure.
- Strong bonding: Provides extra durability by bonding directly to the tooth.
- Versatile use: Can be used for broken, cracked, or gap-filling teeth, as well as for aesthetic purposes.
- Mercury-free: Unlike amalgam fillings, they do not contain mercury.
- Quick application process: Can be applied quickly and usually in a single session.
Composite dental fillings provide many advantages in terms of health and aesthetics compared to amalgam fillings.

| Preservation of Tooth Structure: | Requires minimal removal of healthy tooth tissue | Requires more removal of healthy tooth structure |
| Durability / Lifespan: | Typically lasts 7–10 years with proper care | Typically lasts 10–15 years or more |
| Cost: | Generally more expensive than amalgam | More affordable option |

Procedure of Getting Composite Filling
The composite filling procedure aims to preserve the natural structure of the tooth both aesthetically and functionally and is usually completed in a single session. The procedure stages are as follows:
What Are The Steps Of Composite Filling Procedure?
1 – Preparation Stage
- Examination and X-ray: The dentist evaluates the tooth to be filled and its alignment with the surrounding teeth. If necessary, an X-ray is taken to identify cavities, cracks, or old fillings. This ensures that the healthy tissue of the tooth is preserved and the most appropriate treatment plan is developed.
- Local Anaesthesia: Discomfort during the procedure is minimised.
- Cleaning The Tooth: Decayed or damaged tissue is gently removed. The tooth surface is lightly roughened and a bonding agent is applied
2 – Application Stage
Layering the Composite Material:
Filling material that matches the tooth colour is applied in layers, and each layer is hardened with a special light. This method ensures that the filling is both durable and natural-looking.
3 – Shaping & Polishing Stage
Final Touches:
The filling is shaped to match the natural contours of the tooth and the surface is smoothed. This method is ideal for those seeking front tooth aesthetics.
