What is the material made of?
A resin matrix binds fine solid filler particles, such as glass. Composite therefore belongs to a different material group from ceramic, even though both can be tooth-coloured.

What is a tooth-coloured filling made of?
Composite is a tooth-coloured filling material. It combines a resin matrix with fine filler particles, such as glass. The material can be shaped directly at the tooth and, in many applications, is hardened using a special light.

More than resin alone
Composite contains a resin matrix and fine solid filler particles. Composition and properties vary according to the material and intended use.
The material is bonded to the tooth
An adhesive system bonds composite to the prepared tooth surface. Depending on the technique, the material is placed in layers and hardened with a curing light.
Shape, contacts and care matter
The filling is finished and polished, and the bite is checked. Care, chewing forces and defect size influence how the restoration performs over time.

How is it made into a filling?
An adhesive system bonds the material to the prepared tooth surface. Depending on the technique, it is placed in layers and hardened with a special light.
What determines its suitability?
Factors include the defect size, remaining tooth tissue, forces on the tooth and suitable handling. Repair may be possible for limited damage, but needs assessment.

Often confused
Composite or ceramic?
Similar tooth colour does not make them the same material. Composite has a resin matrix; ceramics are inorganic, non-metallic materials.
Quick answers
Is composite the same as ceramic?
No. Composite contains a resin matrix with filler particles. Ceramic is a different group of materials. Both can be tooth-coloured.
Can composite only restore small cavities?
No. It also has applications in larger defects. The remaining tissue, forces on the tooth and suitable handling are among the deciding factors.
Can a composite filling be repaired?
A limited defect can be added to or repaired under suitable conditions. An examination is needed to establish whether this is sufficient.

For your consultation
A question to discuss with Dr. med. dent. Niusha Barahmand Pour:
Can the defect be restored or repaired with composite, and what would support that choice in my case?
In her planning, Dr. Barahmand Pour considers shape, function and existing tooth tissue together. Her profile also lists further training in adhesive restorations for front teeth.
We discuss whether composite suits a tooth in the context of its shape, the forces it bears and the findings.

Build on the simple explanation with clinical terms, key distinctions and a knowledge question.
- Resin matrix
- The organic component of composite in which solid filler particles are embedded.
- Adhesive
- A bonding agent between a pretreated tooth surface and restorative material.
- Light curing
- Hardening suitable composites through a chemical reaction initiated by a special light.
Know the difference
The adhesive provides the bond. The composite replaces tooth tissue. Light curing is a processing step, not a filling material in its own right.
