White Inlays & Onlays are lab made restoration and can be used when your tooth has been weakened by having a very large filling or extensive decay extending under one of the cusps.
Also it is indicated when you have a root filling that will need a crown to protect it also by a large mercury amalgam filling which you would like removed to improve the appearance of the tooth.
Inlays were originally made of gold but in last 30 years mostly made of tooth coloured materials. Zirconium/Porcelain or pressed porcelain are the strongest and most natural materials.
Resin based materials like Belle-Glass are a less expensive alternative but do not retain their appearance for so long.
We will prepare the tooth to the ideal shape, take an impression (mould) of the prepared tooth & give to the dental technician along with an appropriate shade and other information needed. A temporary will be made so that ( mostly for aesthetic). The final restoration is back usually in one week time & will be fitted after you and your dentist are happy with the fit and appearance of it.
