Composite Fillings for Sonoma Patients

About This Service

Tooth-Colored Fillings

A cavity is a hole in your tooth. The decay has eaten through enamel and into the softer dentin layer below. A filling seals that hole and restores the tooth's shape and function. Tooth-colored composite fillings (made of resin and fine ceramic particles) have become the standard because they match your natural tooth color, require less drilling of healthy tooth structure, and bond directly to what remains. The reason we prefer composite fillings is straightforward: they look better and preserve more of your original tooth. Metal amalgam fillings (which contain mercury, silver, and other metals) are still durable and less expensive in some cases, but they show dark gray inside your mouth, they expand and contract with temperature changes slightly differently than tooth, and they require removing more healthy tooth structure to place them properly. Composite fillings shade-match your tooth, flex slightly like natural tooth does, and bond to the remaining structure, actually reinforcing it. At Bonin Dental Care, we use shade-matching technology and placement techniques that prioritize esthetics and function. Whether you're replacing an old filling that's worn out or treating a newly discovered cavity, Dr. Bonin will use composite resin. The appointment is straightforward: numb the area, remove decay, shape the remaining tooth, place the composite in layers, harden it with special light, and adjust the fit so your bite feels natural.
