As a result of the recent advancements in the materials, technology and science of dentistry, we can now offer many options to our patients to restore (fill) cavities. The choice of which method and technology to use depends largely on the size of the decay, amount of healthy tooth structure remaining and the function of the particular tooth in the bite.
Tooth Colored Composites
These are usually one, two or three surface restorations that are composed of a matrix and microscopic filler particles (advanced plastics). Composites are relatively economical and can be done relatively quickly. On the down side, they tend to stain and develop decay around their borders over time due to the inherent “shrinkage at the margins” phenomenon. If the cavity is small, a tooth colored composite is the most sensible restoration.
Porcelain Inserts (partial crowns and onlays)
For teeth that have larger cavities and that involve multiple surfaces, the restoration of choice is a porcelain insert. A porcelain insert is an extremely strong piece of porcelain that fits in a “puzzle piece-like” fashion into the area where the cavity and the old filling used to be. Porcelain does not stain like composite and is a very resilient material. Due to its glass-like properties, porcelain is a very natural and almost indistinguishable from a healthy tooth. Porcelain inserts are pricier and more reliable than composites.

Crowns
A crown is a restoration that circumferentially holds the tooth together and is usually indicated where a large portion of the tooth is either decayed, missing or has a failing composite or amalgam (old silver filling). Crowns are also indicated if the tooth has undergone root canal therapy whereby it has been devitalized and rendered brittle.
CAPTEK crowns are state of the art porcelain fused to gold restorations. According to different studies, a CAPTEK crown accumulates 74-92% less bacteria than a traditional crown or even a healthy non-restored tooth. CAPTEK crowns are also very cosmetic in that they have a very natural appearance that is devoid of the dark gum line defect (oxidation) that many older crowns tend to exhibit over time. CAPTEK crowns are pricier than conventional crowns and require two appointments to be completed.
