Oral health encompasses the condition of teeth, gums, tongue, and supporting mouth structures critical to digestion, speech, and systemic well-being. Common conditions such as dental caries, gingivitis, periodontitis, and oral candidiasis arise from bacterial plaque accumulation, poor hygiene, tobacco use, or nutritional deficiencies. Early warning signs include persistent gum bleeding, tooth sensitivity, chronic halitosis, and unexplained mucosal lesions. Treatment ranges from professional scaling and fluoride applications to restorative procedures like fillings, root canals, and periodontal surgery, depending on severity. Regular dental examinations every six months, combined with proper brushing and flossing, remain the most effective preventive strategy against progressive oral disease.
