What are tooth colored restorations?
Tooth Colored Restorations (commonly known as “white fillings”) are a metal-free restorative option. They blend in with your natural tooth and they will not crack the remaining tooth structure around them – they are a fantastic option and look completely natural. They are bonded to the tooth and therefore help prevent fractures on teeth.
Dental restorations can be divided into two types: direct restorations and indirect restorations.
Direct tooth colored restorations
Direct restorations are done using dental composite (white color). If filled by white composite, the filling is photo-polymerised using a blue spectrum light, not to be confused with UV light.
Indirect tooth colored restorations
Indirect restorations are not fitted in the patient’s tooth directly. Usually a dental technician fabricates the indirect restoration from records the dentist has provided of the prepared tooth. Once a proper fit and bite is confirmed the restoration is usually bonded permanently.
Indirect restorations include inlays and onlays and in-onlays. They are made of composites or ceramics.
Like a crown, porcelain Inlays and Onlays are used when a tooth is too damaged or decayed for a filling. Inlays and Onlay are similar to a crown, in that they cover and protect the tooth surface, but while a crown covers the entire tooth, an Inlay or Onlay covers only the cusps and/or biting surfaces to preserve as much healthy tooth structure as possible.
Why do we make tooth colored restorations?
- White fillings are the same colour as teeth. They come in a range of shades so they can be matched to the colour of your own teeth.
- White fillings are sticky so they can be used to reshape and rebuild broken edges or worn teeth.
- A tooth needs less preparation for a white filling than for a silver filling.
