Tooth-Colored Fillings

Dentists no longer need to rely on unsightly metals to replace tooth structure lost to decay, but use high density, state-of-the-art plastic.

In the past, teeth were filled with a mixture (or amalgam) of different metals. Today that is changing as more natural-looking and metal-free dental fillings are becoming the preferred approach.

Dentists are using more tooth-like materials (composite resins and porcelains) that are both safe and predictable. The most important feature for many people is that the cavity filling looks and reacts more like natural teeth.

The Make-up of a Tooth

Tooth bonding is used in several different ways but is probably most useful for repairing chipped teeth. Bonding materials (high-density, space-age plastics called composite resin) and porcelain are more natural in color and can be designed to perfectly match the surrounding teeth, making it difficult to discern there ever was a broken tooth.

Transitional bonding is used for anything from a mock-up to a full-mouth rehabilitation. It’s called transitional because it allows the patient to transition into more permanent dentistry as he or she can afford, or as the treatment sequence demands, and it allows the dentist time to work out any bite related and aesthetic issues. Transitional bonding is an important tool in the skill set of an accomplished cosmetic dentist.

Bonding

Metallic cavity fillings or amalgams could not bond with the tooth; they merely rested on it and provided a degree of protection. Today, so much more is known about the interface between dentin and enamel and the bond created between these two natural products. This has led science to discover new ways of bonding fillings to teeth to create a stronger, more protected connection and also more comfortable dental fillings.

Rebuilding Teeth

Restoring teeth, or literally rebuilding them successfully, depends on a good bond between resin materials and both the enamel and dentin. Restorative dentistry recreates a tooth that not only looks natural but responds naturally too, allowing bite stress to pass through the tooth while receiving biting force.

Using Nature as a Guide

In the past, dentistry focused on creating “stronger” teeth by using very durable, rigid materials to replace decayed or damaged teeth. These rigid materials actually contributed to further decay by allowing additional decay and cracking to occur. Today, dentistry uses nature as a guide by constantly looking for materials that more closely mimic teeth in form and function. It is a combination of art and science that takes into account the action of the tooth being restored and its internal shape. A tooth, or portion of a tooth, is then recreated using materials that respond as a healthy tooth would.

Immediate Dentin Sealing– Immediate dentin sealing uses a resin coating to seal and protect the dentin surface from bacteria and sensitivity. It also creates a hybrid layer to which composite resin can be bonded for shaping into a tooth structure.

Dentin Build-Up– This is simply the layering of resin to fill any voids and recreate the original tooth’s shape. One problem with metal or amalgam fillings is that they need undercuts to hold them in place. The use of undercutting removes some of the healthy tooth and can lead to weakening and future cracks. Resin dentin build-ups don’t have this problem.

Restorations

Direct, semi-direct, or indirect are three different methods to repair teeth with restorative materials or fillings. Each method has its own benefits and drawbacks and is best suited for a specific set of circumstances.

Direct Fillings– Direct fillings require small amounts of restorative materials being placed into cavities resulting from decay. The resin is applied in layers which are instantly set with special lights, meaning the entire filling can be built up and repaired by the time you leave Golia Dental.

Semi-Direct Fillings– Semi-direct fillings are for repairing larger areas. These are similar to direct fillings, in that layers of resin are used, but this restoration can be removed and is set outside of the mouth. Once the filling has set, it is then bonded to the tooth. Semi-direct fillings can also use CAD/CAM (Computer-Assisted Design/Computer Assisted Milling) to create the inlays. This technology allows Dr. Robert T. Golia to make a harder, more durable porcelain restoration without having to send out a mold to a remote fabrication facility.

Indirect Fillings– Indirect dental fillings are used when a very large or complex restoration is required. Basically, when there is not enough healthy tooth left to fill, a restoration is created to replace most of the visible tooth, or to crown it. These are more involved procedures and cannot be made directly to the tooth and cannot be placed the same day.
