Modern Advances for Safer Fillings
We do not use mercury at our practice. Nonetheless, numerous patients still have mercury/silver dental fillings from previous years. Normally, these fillings are a mixture of tin, copper and silver held together with roughly fifty percent mercury. Fillings like these are not aesthetically pleasing and due to the way they are designed they weaken the structure of the teeth.
Do Composite Fillings Look Different?
Tooth colored restorations and porcelain inlays produce fillings that are both attractive (or invisible) and effective at strengthening weakened teeth. As well as being pleasing to the eye, these restorations are extremely strong thanks to recent bonding technologies.
Composite restorations use a material made from multiple chemical compounds renown for their low cost and durability. These artificial resins consist of compounds such as dimethacrylates, Bis GMA monomers, and other components the dentist might opt to add to tailor the mixture to the patient’s requirements. It is fairly common for silica to be used as filler to generate a stable formula.
What is the Composite Restoration Process?
When performing composite restorations, the dentist numbs the area being worked on, then removes any tooth parts that have been damaged. After this, the rough edges are smoothed over as thoroughly as possible. Next, the dentist will check that the nerve of the tooth is protected, before drying the tooth completely. Finally, the hole gets injected with composite resin, before being cured or dried with a blue LED light.
Primarily, the appeal of composite dental fillings relates to their cosmetic advantages. They can be used to partially replace teeth that are damaged in a material that closely resembles the original tooth. Better still, the resin strengthens the tooth by chemically bonding to its structure. Unlike mercury/silver fillings, composite dental fillings are effective at fixing cracked, worn or finely chipped vertical segments of teeth, which would appear unnatural if fixed with metallic inlay.
