Dental Inlays and Onlays are restorations used to repair rear teeth with mild to moderate decay, or that have been cracked or fractured, but not sufficiently damaged to require a crown.
A dental Inlay is like a filling and fits inside the cusps (bumps) of the tooth.
A dental Onlay is more extensive and extends over the cusps (bumps) of the tooth.
Inlays & Onlays can be made from resin, porcelain and gold. However, porcelain and resin are more popular as they can be coloured to match your existing teeth and look more natural.
