What are these newer more healthy materials?
Over the years as dentistry has evolved, there have been a growing number of options available for repairing and restoring teeth. The goal of dentistry has always been to develop materials that would simulate natural tooth structure as closely as possible, in both appearance and physical properties, and avoiding any potential harmful side effects.
In the past few years there has been a growing concern for the potential health hazards with the use of the “mercury” amalgam fillings
. Mercury is one of the most toxic metals found in nature and is a major component of the old silver fillings. If there is a stronger, more beautiful material available, why would anyone not choose that option?
In addition to the “mercury” concerns, when choosing a restoration we have to consider the size of the tooth defect that is being repaired, the function of the tooth and the biting surfaces involved. Strength, durability and esthetic-cosmetic acceptability are all considerations when choosing the best material to use.
Composite fillings are a tooth colored material that is a combination of glass-like particles and a resin. This type of material strongly bonds to the tooth and the glass-like particles make this material resistant to wear.
