When treating a cavity, the dentist will remove the decayed portion of your tooth and fill it with another substance. This procedure is called a filling. There are multiple options for the material to be used in the filling, the most common of which are composite fillings and amalgam fillings.
A composite filling is also known as a tooth colored filling, since the material used in the filling can be closely matched to the color of your teeth. Composite fillings provide good durability for small to medium cavities, and the procedure typically involves removing less of a tooth than you would during an amalgam filling. They are also particularly well suited for treating front or highly visible teeth because of their natural look.
When can a composite filling be used for?
Decayed tooth (i.e. cavity)
Chipped or broken teeth
Decreasing the gap between teeth
How its done
After the dentist numbs the area where the filling is to be placed, he will remove any decayed portions. A substance is then applied to help open up the pores of your teeth for a stronger bond, and hardened and cured with a special light. Once this is complete, the filling is applied in thin layers to slowly form the complete filling. After the composite has hardened, the filling will be smoothened and polished to be comfortable and fit your bite.
Frequently Asked Questions
Q. What are composite fillings?
A. Composite fillings — also called tooth-colored fillings — are resin restorations that match the natural shade of your teeth. They are used to repair cavities, chipped or broken teeth, and to close small gaps, providing a durable and aesthetically pleasing result.
Q. How do composite fillings differ from silver (amalgam) fillings?
A. Unlike amalgam (silver) fillings, composite fillings blend seamlessly with your natural tooth color and typically require the removal of less healthy tooth structure. This makes them especially ideal for visible front teeth and cosmetic concerns.
Q. What is the composite filling procedure like?
A. After numbing the area, Dr. Kaminer will remove the decayed portion of your tooth, prepare the enamel for bonding, and then place the composite resin in thin layers. Each layer is cured with a special light, shaped, polished, and adjusted for bite comfort.
Q. Does getting a composite filling hurt?
A. Most patients feel little to no discomfort during the procedure because the area is numbed before treatment. If needed, sedation or anesthesia can be provided to ensure your comfort throughout the appointment.
Q. Are composite fillings covered by dental insurance?
A. Many dental insurance plans cover composite fillings, either fully or partially. Our team can help you understand your benefits and file claims so you get the most out of your coverage.
Q. How long do composite fillings last?
A. With proper oral hygiene (brushing, flossing, regular checkups) and avoiding excessive chewing on hard foods, composite fillings can last many years. Their lifespan varies depending on how much chewing pressure your teeth experience.
Q. Are composite fillings safe for my smile?
A. Absolutely — composite resin is biocompatible and safe when placed by an experienced dental professional. These fillings preserve more of your natural tooth structure and provide a strong bond that supports long-term tooth health.
Q. Can composite fillings be replaced if they wear down?
A. Yes. Over time, even high-quality composite fillings may stain, chip, or wear. During your regular dental exam at our Hewlett office, Dr. Kaminer will check your existing fillings and recommend replacement when appropriate to prevent further decay or damage.
