How is a tooth filled with resin?

Before filling a tooth, the dentist will carefully examine the patient's dental condition to determine the location and extent of the restoration. During the filling procedure, the defective area is disinfected, and specialized instruments and materials are used to precisely remove decayed tissue while preserving healthy tooth structure, ensuring both the durability and aesthetics of the restoration. Additionally, based on the patient's natural tooth color and shape, an appropriate resin material is selected. The light-cured resin is then applied in layers using a light-curing knife. Each layer is cured with a light-curing lamp, shaped appropriately, and excess resin is removed, continuing this process until the cavity is completely filled.
