Fillings are the most popular method of restoring teeth damaged by decay and trauma. Science Daily estimates that the average American has three fillings.
For years, the most popular filling was silver amalgam. However, given the health concerns over the use of mercury, a new composite material was introduced in the 1960s called white fillings.
White fillings look much like the rest of the natural teeth, unlike metal and silver fillings. They also bond to the remaining structure of the tooth, making them strong and durable.
How are white dental fillings applied?
When you visit your dentist for a filling, they will first clean the tooth to be filled. They will then make an incision in the tooth to remove the decayed part of the tooth. The resulting hole in the tooth is then disinfected. The dentist may apply a protective sheath over the nerves before applying the composite filler. The filler is added in layers and cured using a special light.
