Tooth Coloured Fillings
In the past, teeth were most usually repaired with dental amalgam (mercury) fillings or gold restorations. Thanks to advances in modern dental materials and techniques, teeth can now be restored with a more cosmetic and natural appearance. There are different types of cosmetic white fillings currently available. The type used will depend on the location of the tooth and the amount of tooth structure that needs to be repaired and replaced.
Composite Bonding Technique
The latest form of white filling is technically called a Composite. It is made up of a composite quartz resin and usually contains some sort of light sensitive agent. These light -cured composites are exceptionally natural looking and most often bonded into place in one appointment. For this reason, they are often referred to as “bonding”.
Tooth coloured fillings can be used in both the front of the mouth as well as in your back teeth. These materials come in a variety of shades so that they will match the colour of your own teeth. Some of these composite materials have been specifically designed to actually withstand the incredible forces you can exert when chewing on your back teeth.
In order to bond a white filling composite to your tooth it is first necessary to remove the decay, prepare the tooth and then to condition the enamel and dentine. Once conditioned, a thin resin is applied which bonds to the etched surface. The bonding strength of these white fillings is incredibly strong.
With skilled creativity, composites can be used to realistically mimic the colour details and transparency of your tooth, and polished to a beautiful shine. White tooth bonding techniques are quite common, Nevertheless only a very few dentists have the artistic inclination needed.
Advantages of White Fillings:
1- Since they bond to the tooth, composite fillings restore most of the original strength of the tooth. Silver fillings weaken the teeth, making them more susceptible to breaking.
2- Composite fillings restore the natural appearance of the tooth.
3- Teeth restored with white fillings are less likely to develop hypersensitivity to hot and cold than teeth restored with amalgam, if correct techniques are used.
4- Composites fillings are mercury-free. Mercury in the fillings is viewed by some as being toxic.
5- Composites restorations require less removal of tooth structure(less drilling). The size of the hole made for the filling can be dramatically smaller with composites.
