What are Composite Fillings?
Composite (white) fillings are tooth colored dental restorations made of a glass and plastic mixture and they are a great way to restore decayed teeth in an esthetically pleasing way. The color of the filling can so closely matched with the original color of the tooth that the final result is almost identical with the adjacent natural teeth. Composite fillings chemically bond to the teeth with a bonding agent, using a blue ultraviolet curing light. Composite fillings can wear out in a few years, so regular check-ups and if necessary replacements might be necessary in the long run. When composite fillings wear out, depending on the size of the cavity, your dentist might suggest that instead of fillings, inlays are placed in the cavity to restore the tooth to its fullest.
There are many advantage of composite fillings:
– tooth colored, natural looking restorations
– simple procedure
– immediate results
– wide range of usage for cosmetic and restorative dental procedures
Despite the many advantages, composite fillings might also have a few drawbacks:
– they can shrink and wear off with time, so after a few years they need to be changed
– when not taken care of properly, they can get discolored from coffee, red wine, other colored foods and drinks, smoking etc.
– when used in very deep cavities that are too close to the pulp chamber, tooth sensitivity can occur after composite fillings
