Understanding Dental Procedure Codes

Each tooth in your child’s mouth will have a specific identification number. By the age of 3, most children will have their full set of 20 baby teeth. Baby teeth in the upper right are numbered 51 (front)-55 (back); upper left are number from 61-65; lower left are numbered 71-75  and the lower right are numbered 81-85.

In general, baby teeth with small cavities can be fixed with white fillings in both the front and the back teeth.

The procedure codes for white fillings are:

23411-23415: White filling for baby teeth in the front; where the last digit indicates the size of the filling.

23511-23515: White filling for the baby teeth in the back; where the last digit indicates the size of the filling.

If your child’s cavity is very large (close or into the nerve) or around many surfaces of the tooth, a dental crown may have been recommended. Dental crowns can be either silver or white in color. The traditional silver crowns are made out of stainless steel and do not contain any mercury/amalgam. The newer white colored crowns are made from zirconium. Please note that not all insurance plans reimburse the cost of the white crowns.

22211: Stainless steel crown (silver)

22601/22611: Zirconia crown (white)


For patients with deep decay which has reached the nerve of the tooth, a pulpotomy may be recommended.  A pulpotomy is a procedure whereby a potion of the infected nerve is removed and a medication is placed. A silver or white crown is generally recomended for baby teeth which have had a pulpotomy.

32232: Pulpotomy

Teeth which are infected or badly broken down may need to be extracted. If a tooth is extracted early, it may cause the teeth to shift in position, resulting in less space for the adult tooth to erupt. If a tooth is extracted early a space maintainer may be recomended.

71101: Simple extraction

15101: Band and loop space maintainer



Lastly, to prevent cavities in your child’s permanent molars, a dental sealant may  be recommended. A dental sealant is a white protective coating th

at covers the grooves on the biting surface of adult molars, with the ultimate goal of preventing dental decay.


X-ray codes may also be included in your plan:

02142:  Bitewing x-rays used for diagnosing cavities in between the teeth

02111: Periapical x-ray used for diagnosing infection in teeth

02131: Occlusal x-ray used to detect cavities or infection in the front baby teeth

Sedation codes (billed by time)

92413: Laughing gas or nitrous oxide (mild sedation)

92434: Oral sedation + laughing gas (moderate sedation)

92218 + 92228: General anesthesia and anesthesiologist
