Composite White Fillings
White fillings, also known as composite resin material, are made of tooth colored mixture of plastic and glass particles. The composition of composite material differs; percentages of resins, silane and glass fillers vary in the types of composite material. Generally, composite materials have light sensitive agents that are bonded to teeth via an intense light beam. Upon increasing the bond strength, the strength of the restoration increases as well. It is possible to experience some temperature sensitivity for a day or two but should disappear shortly after.
Prevention of micro-leakage is crucial; proper acid etch technique is used to ensure proper seal of the margins. Composites fillings are extremely aesthetic; there are many shades available to color match the tooth being restored. Current technology has developed composite materials with increased strength and longevity to withstand day to day forces while satisfying the demand for superior aesthetics.
What are the advantages of dental composite?
Dental composites fillings are extremely aesthetic; these fillings reestablish the natural appearance of teeth. Amalgam fillings, on the other hand can give teeth a grayish color from corrosion and oxidation.
Repairing broken teeth can be both timely and expensive; composite resins are often done in one visit and cost significantly less than alternative restorations.
Unlike amalgam fillings, composite fillings restore most of the tooth’s original strength via the lined bond layer on the preparation.
Composite material can be repaired if there is a chip or crack. An adhesive bonding agent is applied which can bind new composite to old creating a crack-free, smooth surface.
Ultimately, when restoring with composite less tooth structure needs to be removed. Preparing the tooth conservatively ultimately allows you to keep more of your natural tooth structure.
