What is Resin Composite? All Your Questions Answered!

Resin Composite is a popular dental material used by dental practitioners for restorative and cosmetic purposes. This article sheds light on some of the frequently asked questions about Resin Composite.

What is Resin Composite?

Resin Composite is a tooth-colored mixture of plastic and glass that is used for various dental procedures. It is a versatile dental material that can be used for restoring teeth, improving the aesthetics of the smile, and repairing dental damages like cracks, chips or fractures.

Resin Composite is a popular choice among dental practitioners because of its tooth-like appearance, superior bonding strength, durability, and easy workability. It is an excellent restorative material for patients who seek a natural-looking repair of their teeth with minimal discomfort.

What are the Types of Resin Composites?

Resin Composites are categorized mainly based on their filler content, which determines their strength, translucency, and wear resistance. The two main types of resin composites are:

Microfilled Resin Composites

Microfilled Resin Composites are suitable for aesthetic dentistry due to their excellent translucency and color-matching properties. They have smaller fillers and are more flexible than other types of resin composites. However, they lack the necessary strength and wear resistance required for posterior teeth.

Macrofilled Resin Composites

Macrofilled Resin Composites contain larger-sized fillers, which give them superior strength and wear resistance. They are ideal for the posterior teeth due to their robustness and durability. However, they may lack translucency and the ability to match the color of the natural teeth.

What are the Advantages of Resin Composite over Other Restorative Materials?

Resin Composite has many advantages over other restorative materials, including:

  • Tooth-like appearance, which blends well with the natural teeth and improves the aesthetics of the smile
  • Superior bonding strength, which ensures that the filling is firmly attached to the tooth, making it less likely to fall off or get dislodged
  • Easy workability, which allows the dental practitioner to shape, polish and refine the composite to match the other teeth easily
  • Minimal tooth preparation required, which means that the dental practitioner only needs to remove minimal tooth structure before placing the composite filling
  • Less sensitivity to temperature changes
  • Less risk of tooth cracking or fracture due to the bonding strength of the composite to the tooth structure

When is Resin Composite Used?

Resin Composite is used for various dental procedures, including:

  • Filling cavities after decay removal
  • Replacing old or worn-out fillings
  • Bonding veneers or crowns to the teeth
  • Repairing chipped, cracked, or fractured teeth
  • Changing the shape or size of teeth
  • Closing gaps between teeth

How is Resin Composite Placed on the Teeth?

The placement of Resin Composite on the Teeth is done as follows:

  • The dental practitioner numbs the tooth and surrounding tissues to prevent pain during the procedure
  • The decayed or damaged part of the tooth is removed and cleaned
  • The tooth is etched with a special solution to roughen its surface and create a strong bond between the tooth and the composite material
  • The composite material is applied in layers to the prepared tooth and shaped to match the natural tooth shape
  • A curing light is used to harden the composite filling, after which the dental practitioner will polish and refine the composite filling to improve its appearance and function

What is the Cost of Resin Composite?

The cost of Resin Composite varies depending on various factors, such as the location of the dental practice, the number of teeth requiring filling or bonding, the size and complexity of the procedure, and the type of composite material used. In general, the cost of Resin Composite is comparable to other restorative materials, such as Amalgam or Gold.

Conclusion

Resin Composite is a versatile dental material that has revolutionized restorative and cosmetic dentistry. It offers a natural-looking and durable alternative to traditional restorative materials and can help improve the aesthetics, function, and overall health of the teeth. Its ease of use, superior bonding strength, and tooth-like appearance make it an excellent choice for both dental practitioners and patients.

Questions and Answers

Here are some of the most common questions about Resin Composite:

  • Q: How long does a Resin Composite filling last?

    A: Resin Composite fillings can last anywhere between 5 to 10 years, depending on various factors, such as the location of the filling, the size and complexity of the filling, and the oral hygiene habits of the patient.
  • Q: Is Resin Composite safe?

    A: Yes, Resin Composite is safe and has been used in dentistry for several decades. It does not contain any harmful substances such as mercury.
  • Q: Does Resin Composite hurt?

    A: No, Resin Composite does not cause any pain during the procedure, and it is generally less sensitive to temperature changes than other restorative materials.
  • Q: How long does it take to place a Resin Composite filling?

    A: The time required to place a Resin Composite filling varies depending on the size and complexity of the filling. A simple filling can take anywhere between 30 minutes to an hour, while a more complex filling can take multiple visits.
  • Q: Is Resin Composite covered by dental insurance?

    A: Yes, most dental insurance plans cover Resin Composite to some extent, depending on the type and location of the procedure.
