Composite Fillings | Gallatin TN
We are not a mercury-free practice. However, many people do not want their child to have silver fillings in their mouths because of the mercury content. Silver fillings are not esthetically pleasing and we know that by unavoidable design, silver fillings could result in a weaker tooth structure. Tooth-colored resin restoration fillings can be serviceable if maintained and appropriately cared for. Not only are these restorations beautiful, sometimes even unnoticeable, but they also can add strength to weakened teeth. These restorations are esthetically pleasing and very strong thanks to new bonding technologies.
Advantages of Composite Restorations
There are many advantages to choosing tooth-colored restorations. Composite restorations are bonded to the teeth creating a tight, superior fit to the natural tooth. Dr. Andy has to remove less tooth structure to complete the filling and the result is often stronger due to the bonding. Since the resin used in tooth-colored restorations contain fluoride this can help minimize the development of new decay. The resin wears similarly to your remaining natural teeth.
Disadvantages of Composite Restorations
There are a few disadvantages to tooth-colored restorations. They are softer than natural tooth material and may wear more rapidly. Shrinkage is another common problem with these types of fillings, especially during light curing. Composite restorations are moisture-sensitive because adhesion of the filling material to the tooth is dependent upon keeping the entire area perfectly dry. Composites used in posterior restorations (back teeth, or molars) are more prone to failure because of the immense forces placed upon them during chewing. They are technique-sensitive, meaning that an exact, meticulous protocol must be followed–a protocol that is time consuming for the patient and the practitioner. Composites can deteriorate and discolor around the edges. Composite material do contain trace amounts of bisphenol-A.
