A filling is necessary when a tooth has been damaged by having a cavity, trauma or wear. Once the damaged part of the tooth has been removed, the tooth can be repaired with a filling. These are made out of silver mercury amalgam or white resin. Amalgam is held in by friction, white fillings are bonded in place.
Dickon provides white fillings only.
These have many benefits over silver fillings. They bond to the tooth and so provide some support to the remaining tooth. This can prevent leakage around the filling as they are sealed.
They do not corrode in your mouth or release mercury vapour.
They can be kept very small as they do not need to be extended to provide mechanical ways to keep them in.
They can be easily repaired.
They look good!
If fillings are going to be very large it may be necessary to have a porcelain inlay (This is a filling that is made in a dental laboratory and then cemented in place). It may be too difficult to construct a quality restoration freehand in the mouth if it is large.
Are white fillings weaker than silver fillings?
My experience of white fillings is that they are extremely strong and rarely break. As they bond to the teeth, I have found that the incidence of teeth breaking is very low. With silver fillings the tooth around the filling often breaks requiring further, more extensive treatment. If the tooth breaks around a white filling, it can often be repaired by bonding more of the resin to it.
I believe that resin is now the filling material of choice and that amalgam has had its day!
