The two main diseases that dentistry contends with are decay and gum disease. Decay (the rotting of the tooth) is caused as a result of bacteria, which create an acidic environment that is produced by germs that have settled on the tooth. The way to contend with these issues is to remove the decay and afterwards to complete the missing tooth material.
Two Types of Tooth Reconstructions
Silver colored reconstruction (amalgam) has been around for over 100 years. It offers a strong and effective reconstruction. Yet it has clear disadvantages. About 20 years ago, a stormy debate began in the professional literature regarding the biological suitability of the amalgam structure, which contains, among others, a tiny amount of mercury. In several countries in Europe, the use of this material was prohibited. However, there have been no findings in the professional literature that show connection between amalgam reconstructions and disease deriving from mercury.
The main disadvantage of the amalgam reconstruction is its lack of aesthetics. Over the years, the grayness of the reconstruction passes to the tooth too. The amalgam has other disadvantages. First off, it serves only as a substitute for the gap that has been created and does not bind to the tooth. Second, in order to create a good hold for the reconstruction, a preparation in which more tooth material beyond the decayed tooth material must be removed.
With the rise in aesthetic awareness, white reconstruction materials have been developed for use not only in front teeth but in back teeth too. The materials that in the past have been of low quality have been greatly improved and serve in most reconstructions today.
White reconstructions' most obvious advantage is in its aesthetic value. In addition, the material of the white reconstruction binds to the tooth layer on the microscopic level. A conservative preparation can be done without unnecessary removal of extra tooth layer.
In cases of loss of excessive tooth material, the reconstruction strengthens the remaining structure by its tight binding to all parts of the tooth. Thus, one integral unit is created.
There are white reconstructions that contain fluoride, and thereby lessen the possibility of the development of decay alongside the reconstructions.
The disadvantage of the white reconstructions is that they necessitate very precise and meticulous technical constructive ability. The professional literature is loaded with information regarding innovations in the realm of white reconstructions. Being versed in the literature and strict adherence to precise technique will ensure a reconstruction that will hold for many years.
