A filling is the name of the material used to replace the missing part of the tooth that results from having a cavity or decay on a tooth.

In our office we only do white fillings. The reason for this is as follows:

1) They look more like the natural teeth.

2) They are kinder to the teeth. Silver fillings are placed with undercuts so they physically lock into the teeth. Whereas white fillings chemically bond to the teeth. Also, silver fillings expand and contract in response to heat or cold so over time this cracks the tooth.
