Though there has been a slight change in the definition of the dental code d2940 however, it still includes the sedative filling ada code which has not changed.

D2940 Explanation

According to the ADA (American Dental Association), d2940 is a form of dental protective restoration. The restorative material to be used for this purpose is placed directly on the tooth to protect its structure and the tissue. Its status as a direct form of restoration means that the restorative material is placed directly on the tooth and not anywhere else. This procedure can perform a number of functions. 

It can be used to 

  • reduce and relieve any pain
  • facilitate the process of healing 
  • ensure that further harm or deterioration does not happen to the teeth.

The individual in question has to decide the use of the restorative process. In case of an emergency, the restorative process can be used. The dental procedure code d2940 can also be claimed in case of a need to facilitate the process of healing, which happens when the decaying process is close enough to cause discomfort for the nerve ending in the tooth. Additionally, when preventing further harm or deterioration to the tooth and the tissue around it, it is highly likely that the tooth is fractured, and the restorative process is meant to protect against and avoid further fracturing until a more definitive process can be figured out.

For the dental procedure d2940, a number of materials can be used. These include glass-based ionomers, Cavit and IRM (Intermediate Restorative Material). The purpose of the protective restorative material is to protect the form of the tissue and the tooth.

While applying dental code d2940, it is important to remember that the applicability of the code is only a temporary solution. Along with d2941, dental code d2940 must be used in a temporary capacity and it must be ensured that it does not result in further problems.

It is important to keep in mind what dental code d2940 cannot be used for. In 2015, some changes were made to the dental code for filling, which helped establish that dental code d2940 cannot be used for the purpose of final lining or creating a base or endodontic access closure filling. Placing a base or liner on the tooth is a part of the restorative process and cannot be carried out or considered separately. 

When is dental procedure code d2940 used?

Dental code d2940 can be used in a number of situations, particularly when the tooth is in or close to a condition of extreme decay. If the operator/ doctor is unsure of how the tooth will work after the decaying and decay-causing material has been removed, dental code d2940 can also be used. This form of sedative dental filling is also used when the procedure revolves around control of the decaying area before a more comprehensive plan can be put together, or in the case of an emergency.

Can d2940 be reimbursed by insurance or dental plans?

The answer to this question depends on the type of insurance being used by an individual. Given the nature of the dental procedure that is being performed, the outcomes can vary. In some cases, it can be considered by the insurance company which will provide insurance for each tooth once in a lifetime. It must be remembered that if this procedure is paid for by the insurance company, the company might deduct a certain amount if a restorative crown is performed at a later date. For some dental insurance plans, it might not be possible to perform a dental procedure on the same tooth for a given time period, ranging from 30 to 90 days. For example, d2940 payment can be denied by the insurance company if another dental procedure involving an endodontic code or protective restoration process is carried out.


It is imperative to have a basic understanding of the dentist teeth codes. However, if you’re still unsure and need further guidance, it is highly recommended to consult a dental billing services company for a smoother dental billing process. Overall, the d2940 is a dental code for temporary filling when you’re unsure of how the tooth will react after a decay removal and is thus used for protective restoration measures.
