What your first examination involves, and why it takes 45 minutes to an hour
The examination starts with a medical history, not as a formality, but because systemic conditions, medications, and allergies change how we diagnose and how we treat. After that comes the extraoral examination: the lymph nodes, the temporomandibular joints, the muscles of mastication, the facial symmetry, and the skin around the mouth. Then the intraoral soft-tissue screening: every surface of the oral mucosa is systematically inspected for changes in colour, texture, or morphology that may indicate early pathology. None of this involves a drill or a treatment plan; it is data collection. Then the radiographic survey: a full-mouth series of periapical and bitewing radiographs, or a panoramic radiograph supplemented by bitewings, chosen based on the patient's clinical presentation. The systematic-review evidence on radiographic caries detection confirms that bitewing radiographs remain a key tool for identifying proximal caries that visual examination alone misses [1], while a 2021 meta-analysis of early caries detection concluded that no single method is reliable enough on its own, so radiographs and other aids should support a careful clinical examination rather than replace it [3].
After the radiographs comes the periodontal charting: six probing measurements per tooth, recorded systematically, producing a full map of the attachment levels and pocket depths throughout the mouth. This is not an optional extra; it is what the current periodontal classification system, the staging and grading framework published by the 2017 World Workshop on Periodontal and Peri-Implant Diseases, requires for a diagnosis to be made at all [4]. Without this data, the clinician cannot distinguish between early gingivitis that needs only better home care and advanced periodontitis that needs active treatment immediately. We also take a full set of intraoral photographs (at minimum: retracted frontal, left and right lateral, upper and lower occlusal views), because photographs are the only record that captures colour, texture, and spatial relationships in a way that written notes and radiographs cannot. The whole process takes time, and that time is what lets every later decision rest on your own data. Conservative dentistry depends on it.
