D2394 resin-based composite - four or more surfaces, posterior

When a tooth develops a cavity or other structural damage, it often requires a dental restoration to repair the affected area and prevent further decay or damage. One common restoration procedure is the placement of a resin-based composite filling, particularly for cavities on the chewing surfaces of posterior (back) teeth.

The ADA dental code "D2394 resin-based composite - four or more surfaces, posterior" refers to a composite filling that covers four or more distinct surfaces of a posterior tooth. This type of extensive restoration is typically needed when a tooth has significant decay or damage that affects multiple areas of the tooth.

On average, patients pay $400 for this D2394 service at the dentist's office, with as little as $250 charged for this in less expensive cities and as much as $480 in more expensive cities.

However, the price for the service D2394 depends not only on the region where you live, but also varies from dentist to dentist. Therefore, it makes sense to compare prices before choosing a dentist. The best way to do this price comparison is at Dr. BestPrice and save a lot of money. 

Administering a local anesthetic is a critical first step to ensure the patient's comfort and cooperation throughout the procedure. The dentist will carefully inject a numbing solution into the gum tissue around the affected tooth. This blocks the transmission of pain signals from that area, allowing the dentist to work without the patient feeling any discomfort. The numbing effect typically lasts for 2-4 hours, providing ample time for the dentist to complete the restoration. Maintaining the patient's comfort is essential, as they need to remain still and relaxed during the more invasive parts of the procedure.

Using specialized dental tools like high-speed handpieces and excavators, the dentist will meticulously remove all decayed or damaged portions of the tooth. This ensures a clean, stable surface for the composite filling to adhere to. Removing all compromised tooth structure is crucial - even tiny remnants of decay can jeopardize the longevity of the restoration by providing a pathway for future decay. The dentist will carefully shape the preparation, removing enough tooth material to create space for the composite filling while preserving as much healthy tooth structure as possible. This conservative approach helps maintain the tooth's integrity.

To optimize the bond between the tooth and the composite filling, the dentist first applies an etching solution to the prepared tooth surfaces. This solution contains mild acids that create microscopic pits and grooves on the tooth enamel. These microscopic irregularities provide mechanical retention, allowing the composite to mechanically interlock with the tooth structure. Next, the dentist applies a bonding agent, which is a liquid resin material that further enhances the chemical and physical adhesion between the tooth and the composite filling. These etching and bonding steps are crucial for creating a strong, long-lasting restoration.

The dentist carefully layers and sculpts the tooth-colored composite resin into the prepared areas of the tooth. They work in small increments, meticulously adapting the composite to match the original tooth contours and occlusal (biting) surface. This incremental layering technique allows the dentist to precisely control the placement and shaping of the composite to achieve a natural-looking, seamless restoration. Proper adaptation of the composite is essential for optimal function, durability, and aesthetic integration with the surrounding tooth structure.

To harden and set the composite filling material, the dentist uses a specialized high-intensity curing light. This light activates the photoinitiators within the composite, causing it to rapidly polymerize and cure. The curing process typically takes 20-40 seconds per increment, depending on the type of composite used. This ensures the composite achieves its full strength and resistance to wear.

After the composite has been placed and cured, the dentist will use additional tools like abrasive burs, polishing points, and discs to carefully shape, adjust, and polish the restoration. This ensures the filling matches the contours of the original tooth, blending seamlessly with the surrounding enamel. The final polishing step creates a smooth, lustrous surface that is comfortable for the patient and resistant to staining or plaque accumulation.

Resin-based composite fillings offer several benefits, including their ability to be customized to match the color of the natural teeth, their durability, and their conservative preparation requirements compared to other restoration options like metal amalgam fillings. With proper oral hygiene and regular dental visits, these composite fillings can last for many years.
