Restoring the look and feel of natural teeth.
Like a crown, a porcelain onlay is used when a tooth is too damaged or decayed for a filling or other procedure. It’s similar to a crown, in that it covers and protects the tooth surface. But where a crown covers the entire tooth, the onlay covers only the cusps and biting surface.
Onlays are designed to match the natural bite and feel of natural teeth. Unlike fillings, which leave a tooth only half as strong when completed, an onlay restores it to its original strength.
A nice thing about porcelain onlays is that they match the tooth color, so the restoration looks natural and healthy. With proper care, porcelain onlays can last for years.
