Invisible Tooth Coloured Fillings as a Replacement for Amalgam
Traditionally, most fillings have been made from Amalgam, a mixture of silver, tin, copper and mercury. This mixture has proved popular due to its strength and ability to tolerate the grinding and chewing actions which are placed on the back teeth especially.
However, these amalgam fillings are, without doubt, potentially unsightly and with recent advances in the dental industry, it is now possible to have fillings which will match the colour of your own teeth.
As the tooth coloured fillings are not quite as durable as amalgam, they tend to be used for more visible teeth that may show during conversation or when smiling. Often however, they may not be as suitable for the back teeth as amalgam, although newer materials are getting closer to the strength of amalgam. Tooth coloured invisible fillings are generally used for front teeth or small area fillings nearer to the back.
These tooth coloured teeth can be made up of different materials, perhaps the most common being composite and glass ionomer. These have the advantage of being soft initially, and are able to be moulded into an appropriate tooth shape before hardening. As this material is pliable, it also has the ability to stick to other teeth, enabling it to be used to build up chipped teeth, for example.
The procedure for placing tooth coloured filings is very similar to that of traditional amalgam fillings. Depending on the size of the filling needed, our Harley Street dentist will numb the area around the tooth and remove any decay or existing filling. After the tooth coloured filling has been placed, a blue light is shone upon it in order to set the material.
It is important that after placement, these tooth coloured fillings are kept dry until they have set fully, and your dentist may take precautions to divert saliva from the area.
For a short time after the tooth coloured filling has been placed, it is possible that you may experience some sensitivity to hot or cold food and drinks but this should ease fairly soon afterwards. Once the fillings have settled in, usual dental hygiene should be followed, including regular brushing and flossing, and of course avoiding too much sugar intake in your diet.
