Dental caries are cavities in teeth ('caries' is both the singular and plural form). They are very common and can lead to serious morbidity.
Focal enamel and dentin demineralisation result in cavity formation. There are multiple theories for their pathogenesis but contributing factors include a combination of a sugar-rich diet, anatomy, oral cavity microbiome, poor dental hygiene and time 1,2.
Dental caries are often categorised into 1:
- occlusional: affect the chewing surface
- approximal: occur between teeth
