In the case of the teeth damaged by caries, fractured teeth, old amalgam fillings (silver fillings) or certain aesthetic abnormalities it is necessary to create a new composite filling (white filling).
BLACK OR WHITE FILLING?
At least a few books could be written (and have been written) on this eternal subject. We will try to address some things which are in our opinion the most important and the most interesting things for a patient.
It is known that mercury from the amalgam fillings is in time released and accumulated in the body. Numerous researches have been conducted and have determined various negative effects of high levels of mercury in the organism. Mercury poisoning often causes an inexplicable chronic fatigue. Mercury from amalgam fillings reduces the number of T-lymphocyte cells, one of the most important components of our immune systems. Today we have proof that mercury accumulates also in the brain and that it can cause symptoms similar to Alzheimer disease.
The mercury has the ability to disrupt the bacteria in the intestines and to create a resistance to antibiotics. It is believed that amalgam fillings can be partly responsible for candidiasis and for spreading of the allergies which appear abruptly in the middle-aged persons and for the general problem of resistance to antibiotics and supergerms, a problem which occurs in the whole population.
Do you think that all of this is exaggerated? Well, we don't think so. What we state here has truly been tested through numerous research and we do not doubt it at all.
From our own experience we can say this:
in order to make an amalgam filling more tooth substance has to be removed than for a composite filling. The amalgam bonds with the tooth mechanically, which means that a more comprehensive tooth preparation is needed and a part of healthy tooth tissue has to be removed, whereas the composite material is chemically bonded with the tooth, the bond is hermetically complete and only the part of the tooth affected by caries is removed. After the placement of such a filling the tooth is immediately in function, that is to say there is no need to wait for the material to stabilize.
As far as the appearance goes amalgam is far more inferior to the aesthetically pleasing composite materials. The amalgam is available on the market in its GREY colour and we use over 30 different colour nuances in order to be able to reproduce as closely as possible the natural colour and shape of the tooth, as it was before it was damaged.
The durability of amalgam fillings is longer than the durability of composite fillings – we have seen many amalgam fillings older than 10-15, even 20 years which had no caries underneath them. The durability of composite (aesthetic) fillings is shorter – 5 to 10 years on average. However it is proved that amalgam fillings constantly release mercury, which means that in the period of 20 years a lot of it has been absorbed by the organism. In addition the majority of old amalgam fillings has covered up caries lesions and patients haven't noticed them before the toothache started – in other words the caries has reached the pulp chamber and the treatment of root canals is necessary.
So, why is amalgam still used?
It is a lot cheaper than the composite material
It is simpler to use, less time and less knowledge (education) is needed to make an amalgam filling compared to the composite one
well, on the back teeth you can't really see what colour is the filling, can you?
In our ordination we don't use amalgam
We want to point out that the durability of the filling depends mostly on you maintaining your oral hygiene and, of course, on the knowledge of the dentist and the right use of high quality dental materials. For example in our ordination the use of a dental dam is usual – it allows us to make a filling without the interference of saliva which immensely increases the quality and longevity of the filling. We use only the latest nanotechnology composite materials such as Filtek Ultimate and Dentsply Ceram X (the countries of origin of all the materials used in our ordination are exclusively the USA, Japan and the EU) The use of such materials of the latest generation guarantees high quality service for our patients and our peace of mind.
The thing that you can do to reduce the possibility of the development of caries is to maintain your oral hygiene adequately and to pay attention to your diet.
Along with everything else we also recommend regular check-ups at your dentist, every 6 months or once a year, that way we can prevent the problems before they occur or, if they have occurred, we can treat them at an early phase which is less traumatic for the patient and also financially more cost-effective. In the end there isn't anything better than when your dentist tells you that everything is all right, is there?
