Most adults will need at least one Dental Filling in their lifetime. The questions is - which type of filling is the best?
In the ninety's, Dentists began to use alternatives to Dental Amalgam...Composite Resin and Glass Ionomer Cement. Composite Resin (CR) evolved from PLEXIGLASS which was developed to make windscreens for World War 11 aircraft. While CR is incredibly strong and bonds well (sticks) to your tooth's enamel (the outside of your tooth) it does not bond well to your tooth's dentine (the inside of your tooth).
Glass Ionomer Cement (GIC) on the other hand bonds very well to your tooth's dentine (inside) as well as enamel (outside), but is not as strong as Composite Resin. GIC is calcium based and therefore therapeutic for teeth.
That's why I use a combination of both Composite Resin and Glass Ionomer Cement in fillings in a 'sandwich' technique. This lamination technique gives maximum strength and longevity. Shrinkage of the CR as it sets was also an issue. In 2000 I developed a cure 'through' technique to overcome this issue. Teamed with Micro Abrasion (a very small sandblaster) to prepare your tooth's surface for maximum bonding strength (stick-ability) I am glad to say that many fillings I've place over the past 10 years or more look literally as good as new today. They are lasting longer than we could have expected.
Amazing technologies (like Composite Resin -- developed to make WW11 aircraft windscreens and Micro Abrasion), teamed with Dental Techniques (like lamination and cure through) give you a healthier, stronger more attractive smile.
