A filling helps:
- To restore a tooth damaged by decay back to normal shape and function.
- To prevent further decay by eliminating areas that bacteria can enter the tooth.
Which type of fillings is best?
No one type of filling is bet for everyone. It depends on the extent of the repair, whether you have allergies to certain materials, wherein you mouth the filling is required and the costs.
- Tooth coloured filling, composite resins are matched to be the same colour as your teeth. Composites are widely used but may not be the ideal material for large fillings since they may chip and wear over time. They can become stained. Their usual life span is 3-10 years.
- Porcelain fillings are called inlays or onlays and are custom made to fit the size of the cavity from a laboratory. They are bonded to the tooth. The colour is matched to the tooth and they are resistant to stain. Porcelain restoration cost is similar the cost of a gold restoration.
- Gold fillings are made in a laboratory. They are well tolerated by gum tissues and may last more than 20 years. Many authorities consider gold is the best filling material. However, it is expensive, can only be used for back teeth (premolars and molars) due to aesthetic reason.
- Amalgam fillings are resistant to wear and less expensive. They are dark in colour and therefore more noticeable, they are not usually used in visible areas.
