How to Number Supernumerary Teeth

The increasing number of people looking for the dentist services has led to the development of dentist charts that are used in the numbering of human teeth. There are different systems that dentists use in numbering of the teeth with the supernumerary teeth numbering system being one of the most common ways that can be found in most dentist charts.

Supernumerary Teeth Numbering

The supernumerary system of numbering teeth allows dentists to add the number 50 to the value of the number on which the tooth is located. The numbering starts on the upper right jaw with the first teeth being the Molar tooth on this side of the upper jaw. Since it is the first tooth, the supernumerary value of this tooth becomes 51. The next tooth has the value 52 with the last of the eight teeth of the upper right jaw getting the value 58. The upper left jaw continues with numbering with the first tooth getting the value 59 and the last tooth on the extreme side of the upper left jaw, the molar getting the value 66. The lower jaw values for the supernumerary numbering run from 67 to 74 in the lower left jaw and 75 to 82 on the lower right jaw. This system remains as one of the best for dental teeth numbering in the dentist charts.

Supernumerary teeth numbering

It would be important to point out that the supernumerary teeth numbering system varies from one country to another. The system that is used in the United States varies greatly with one used in some European countries like Germany. The United States system allows for the numbering of the teeth by adding up 50 to the number of the teeth where one starts from the extreme molar tooth that is in the upper right jaw with the last teeth given the value of 16 being the Molar tooth in the extreme part of the upper left jaw. When these teeth are numbered supernumerary the values become 51 for the first tooth on the upper right jaw and 66 for the last molar teeth in the upper left jaw. This totally different from the system of numbering in most European countries where most dentists prefer to use alphabetical order values in the numbering of teeth in their charts. The need to have a uniform system of numbering teeth in the world has led to the suggestion of adopting the US supernumerary system by some dentists. Whether these suggestions will be adopted by the dentists is something that we eagerly await upon, only time will tell.
