How our Clapham patients can gain from having tooth coloured fillings.
The most obvious reason for choosing a white coloured filling over the standard type is that they simply look much nicer.
There is little doubt that many patients of the Confidental Clinic in Clapham have benefitted in this way, by having this cosmetic treatment, but is that the only benefit that they gain?
There is no doubt that standard amalgam fillings offer very good strength, but they are also dark in colour. That is not their only disadvantage though.
Less extensive fillings
It might surprise patients to know that when a white filling is used, it is often possible to fill the tooth by removing less of the natural part of the tooth. This is because the decayed tooth needs to be shaped in a way that that allows the amalgam to be secured. White fillings, on the other hand, bond directly to the tooth, meaning that the tooth does not have to be shaped to the same extent and less natural tooth needs to be removed in many cases.
Although it is possible to have amalgam fillings for many years without trouble, the metals used in amalgam fillings will gradually shrink. When they do this, it can leave tiny gaps at the edges of the filling, leaving a space between the filling and the natural tooth. Whilst this usually has little effect on the immediate functionality of the filled tooth, it does provide a space where bacteria and acids can enter. When this happens, it often results in new decay at the edges of the fillings. Further fillings may then be needed.
