Dental restorations or Restorative dentistry refers to dental procedures that repair or replace a tooth. The tooth structures can be missing due to decay, deterioration or fracture of tooth. Dental restorations can fix those problems. Restorative procedures include fillings, crowns, implants, bridges, dentures and root canals. Dentists or orthodontists performing these procedures can rely on professional dental billing services to submit claims on time with accurate codes. These procedures are done for diverse purposes such as – to restore the function of the teeth, improve the appearance of the teeth, prevent further dental issues, eliminate the pain caused by infections or preserve the bone density.

CDT Codes for Different Types of Dental Restorations

Crowns and Bridges

A crown is an indirect tooth restoration method, where a tooth-shaped “cap” is placed over a tooth to restore its shape, size, strength and appearance. A crown is used to cover – multiple decays on the same tooth, root canal treated tooth, or to support the tooth having a large restoration, when the filling or the tooth are showing signs of fracture. It is also recommended to hold a “bridge” or to cover a dental implant. It can make the tooth stronger and enhances the way it looks and restore the healthy color as well as its function to the tooth. They are made from different materials – metal alloys, ceramic, porcelain, porcelain fused to metal or a composite resin. During a crown placement procedure, the top part of the tooth is shaved down and the crown is placed over the top.

A bridge is an artificial tooth suspended between two crowns or one or more crowns splinted together to cover multiple damaged teeth. Bridges can be secured on both side by crowns and cemented permanently into place. They are made of porcelain, gold, alloys, or a combination.
These procedures can be reported on dental claims using codes such as

  • D2710 Crown – resin-based composite (indirect)
  • D2712 Crown – ¾ resin-based composite (indirect)
  • D2720 Crown – resin with high noble metal
  • D2721 Crown – resin with predominantly base metal

Fillings

Fillings are a common dental restoration method, where dental cavities and are typically filled using an amalgam or resin based material. Tooth decay or dental cavities are caused by bacteria or poor oral hygiene. Left untreated, bacterial infection will spread and cause structural problems that require more complex procedures. During the procedure, the dentist will remove the decayed part of the tooth and fill the hole with composite material to prevent the bacteria from continuing to infect the tooth. These fillings are made of gold, silver amalgam, or tooth-colored plastic and glass materials called composite resin fillings. Ceramic/porcelain fillings are more durable and long-lasting than composite resin.

Implants

Teeth with severe decay or damage or missing teeth can be replaced with dental implants. Dental implants are replacement tooth roots. To benefit from this procedure, patients should have a healthy gum and enough bone to hold the implant. Two methods for implant restoration are – screw-retained or cemented. Screw-retained restoration has more advantages, as it can be more easily repaired in case of problems with a crown being fractured. These implants also function as anchors for bridges and dentures.

Dentures

Dentures are the best replacement option if there are not enough healthy teeth in the mouth that function properly. Gum diseases, tooth decay, or any injury can lead to missing teeth. Dentures are made of acrylic resin or can be combined with metal attachments. Three types of dentures are conventional, immediate or overdenture. While complete dentures replace all the teeth, partial dentures are considered when some natural teeth remain. Removable dentures are attached to the gums via suction and implant-supported dentures are supported by a few dental implants in the jaw.

  • D5120 Complete denture – mandibular
  • D5130 Immediate denture – maxillary

To get the CDT codes assigned right, it is important for the practice’s billing and coding team to be up to date with the coding changes and guidelines. It is ideal to partner with an experienced dental billing company to ensure error-free claim submission.
