A composite dental filling is a modern restoration material used to repair teeth that have been damaged by decay, minor fractures, or wear. Made from a mixture of resin and finely ground glass particles, composite fillings are designed to closely match the natural color of teeth, making them an ideal choice for visible areas of the mouth. The process involves removing the decayed or damaged portion of the tooth, thoroughly cleaning the area, and then applying the composite material in layers. Each layer is hardened using a special curing light, and the final result is shaped and polished to blend seamlessly with the natural tooth structure.
Composite fillings offer many benefits, making them a popular choice for dental restorations. Their tooth-colored appearance provides an aesthetically pleasing alternative to silver amalgam fillings, ensuring that the restoration is virtually undetectable. Additionally, composite fillings bond directly to the tooth, which strengthens the overall structure and minimizes the need for extensive removal of healthy enamel. They are highly versatile and can be used to repair both front and back teeth. Composite fillings also resist staining and wear over time, providing a durable and long-lasting solution. For patients seeking a functional, natural-looking, and minimally invasive treatment, composite fillings are an excellent option.
Composite fillings are made from a tooth-colored resin that bonds directly to your tooth, unlike the silver amalgam fillings common a generation ago. Because the material matches your natural tooth color, most people can't tell you have one.
With good oral hygiene, composite fillings typically last 5 to 10 years, and sometimes considerably longer. How long yours lasts depends partly on where it is in your mouth — fillings on chewing surfaces wear faster than ones on the front of a tooth.
No. Composite resin is a mercury-free, tooth-colored material, which is one of the reasons it's replaced amalgam fillings in most modern practices, including ours.
Yes — filling a cavity is typically a same-day procedure. We numb the area, remove the decay, and bond and shape the composite resin directly, so you leave with a finished, natural-looking tooth the same day you came in.
Common signs include sensitivity to hot, cold, or sweets, a visible dark spot on a tooth, or a rough edge you can feel with your tongue. Sometimes decay doesn't cause any noticeable symptoms at all, which is part of why we check for it at every routine exam.
