Caries can be classified by location, etiology, rate of progression, and affected hard tissues.<ref>{{cite book |author=Sonis, Stephen T. |url=https://archive.org/details/dentalsecretsque0000unse/page/130/mode/2up |title=Dental Secrets |publisher=Hanley & Belfus |year=2003 |isbn=978-1-56053-573-7 |edition=3rd |location=Philadelphia |page=130 |url-access=registration}}</ref> These forms of classification can be used to characterize a particular case of tooth decay to more accurately represent the condition to others and also indicate the severity of tooth destruction. In some instances, caries is described in other ways that might indicate the cause. The G. V. Black classification is as follows:

* Class I: occlusal surfaces of posterior teeth, buccal or lingual pits on molars, lingual pit near cingulum of maxillary incisors
* Class II: proximal surfaces of posterior teeth
* Class III: interproximal surfaces of anterior teeth without incisal edge involvement
* Class IV: interproximal surfaces of anterior teeth with incisal edge involvement
* Class V: cervical third of facial or lingual surface of tooth
* Class VI: incisal or occlusal edge is worn away due to attrition
