Dental diseases, also known as oral diseases or dental conditions, refer to a range of health problems that affect the teeth, gums, mouth, and associated structures. These conditions can cause pain, discomfort, and potential complications if left untreated. The main aim of this literature review is to identify dental problems such as Tooth Decay (Cavities), Gingivitis, Periodontitis, etc using machine learning and deep learning approaches in dental image analysis which help dentists in their decision-making process while treatment. X-Ray’s and radiographic images are mostly used for detection of dental diseases. Deep learning is a promising approach for dental disease detection and tooth detection, it can achieve high accuracy on dental X-ray images, even when using transfer learning.
