Abstract: Dental Stains are pigmented deposits on the tooth surface which are either extrinsic or intrinsic in nature. A dental stain compromises the aesthetics of an individual. Their prevalence may vary through geographic location, age, sex, habit and diet of an individual. Since there are a lot of variation between different types of stains there is a need to classify them for easy diagnosis and management. As dentists, we should be able to diagnose the type of stains and help those patients by providing them with choices to choose the most conservative treatment plan with an aesthetic outcome. This article aims to give an insight into the prevalence, aetiology and classifications of dental stains
