Periodontal disease, commonly known as gum disease, is a chronic inflammatory condition affecting the tissues surrounding and supporting the teeth. It begins as gingivitis, a mild and reversible form of gum inflammation, and can progress to periodontitis if left untreated. Periodontitis causes destruction of the gum tissue and underlying bone, ultimately leading to tooth mobility or loss.
The primary cause of periodontal disease is plaque, a sticky film of bacteria that forms on teeth. If plaque is not removed through daily brushing and flossing, it hardens into tartar (calculus), which can only be removed by a dental professional. The bacteria in plaque and tartar release toxins that irritate the gums, triggering inflammation, bleeding, and detachment of the gum tissue from the teeth.
As the disease progresses, periodontal pockets—spaces between the teeth and gums—form and deepen, allowing more bacteria to accumulate. Over time, this leads to bone loss, gum recession, and shifting of teeth. Risk factors for periodontal disease include poor oral hygiene, smoking, diabetes, hormonal changes, genetics, and certain medications that reduce saliva flow.
Diagnosis involves a comprehensive periodontal exam, where the dentist or hygienist measures pocket depths around each tooth and takes dental X-rays to assess bone levels. Signs of gum disease include bleeding gums, bad breath, gum recession, loose teeth, and sensitive or painful gums. However, some patients may have minimal symptoms, making regular dental checkups critical for early detection.
Treatment depends on the severity of the disease. Gingivitis can often be reversed with improved oral hygiene and professional cleanings. Periodontitis may require scaling and root planing (deep cleaning), antibiotic therapy, and, in advanced cases, surgical intervention such as flap surgery or bone grafting. Maintenance with regular periodontal cleanings every 3–4 months is vital to prevent recurrence.
In summary, periodontal disease is a major threat to oral and overall health if not properly managed. It is one of the leading causes of tooth loss in adults and has been linked to systemic conditions such as heart disease, diabetes, and pregnancy complications. Preventive care, early detection, and consistent follow-up are key to controlling gum disease and preserving long-term oral health.
