There are times when a filling may be too large for a tooth and can actually cause a tooth to fracture because the cusps are weak and unsupported or if a root canal was performed on a tooth in which it is now weak because the center core was removed. These are instances when the tooth needs to have the cusps “covered” to keep them from fracturing. Crowns or onlays are the treatment of choice in these circumstances.

A crown is a restoration that caps or completely covers a tooth.
There are many different types of crowns, along with different materials that make up the crown. From all-porcelain crowns to gold crowns, each type offers advantages and disadvantages depending on the particular tooth involved and circumstance for which the tooth is to be crowned. These are options that will be discussed with you to achieve the desired result.
Inlays & Onlays
When the decay or fracture of a tooth is more extensive than what a “regular” filling would be used for, an inlay may be the better option.
Additionally, if this decay or fracture undermines a wall or walls of a tooth and the structural integrity of the tooth is compromised then the cusp(s) would need to be overlayed, which is called an onlay.
An inlay is placed within the cusps and an onlay covers one or more of the cusps.
Like a crown there are different materials that make up an inlay or an onlay, each one having certain advantages and disadvantages. These options will be discussed with you to achieve the best result.
The placement of a crown, inlay or onlay requires at least two visits to our office.
During the first appointment, we will remove the decay, shape the tooth, and fit the tooth with a temporary restoration.
On the subsequent visit, the temporary restoration is removed, and the final restoration is adjusted (if needed) and permanently bonded into place..
