Periodontic Treatment — Procedure Guide, Recovery & Risks | MyMedicPlus

Periodontic (periodontal) treatment encompasses a spectrum of non-surgical and surgical procedures to manage periodontitis — chronic bacterial infection of the supporting structures of the teeth, including the gingiva, periodontal ligament, cementum, and alveolar bone. Periodontitis affects approximately 10–15% of the adult population in its severe form and is the leading cause of tooth loss in adults worldwide. The 2017 World Workshop on the Classification of Periodontal Diseases established a severity-based staging system (Stages I–IV) and activity grading (Grades A–C) that guides treatment intensity. Non-surgical therapy — scaling and root planing — forms the foundation of periodontal management, while surgical modalities address residual pockets, regenerate lost supporting bone and attachment, and correct anatomical defects unfavourable to plaque control. Systemic conditions such as diabetes and smoking significantly worsen periodontal outcomes. Periodontal treatment (periodontics) addresses diseases of the supporting structures of teeth — the gingiva (gums), periodontal ligament, cementum, and alveolar bone — caused primarily by accumulation of bacterial biofilm (dental plaque and calculus). Periodontal disease ranges from gingivitis (reversible gingival inflammation) to periodontitis (irreversible loss of bone and attachment), which is the leading cause of tooth loss in adults globally. Comprehensive periodontal treatment combines patient education, non-surgical mechanical therapy (scaling and root planing), and surgical interventions (flap surgery, bone grafting, guided tissue regeneration) for advanced disease. Adjunctive local and systemic antibiotics may be used in aggressive forms. Long-term maintenance therapy — professional cleaning every 3–4 months — is the cornerstone of sustained periodontal health after active treatment, as disease recurs without consistent biofilm control.

Periodontic treatment is indicated for all patients with gingivitis or periodontitis identified by clinical and radiographic examination. Stage I–II periodontitis (mild to moderate pocket depths of 4–5 mm, less than 33% bone loss) is managed with non-surgical scaling and root planing combined with oral hygiene instruction. Stage III–IV periodontitis (pocket depths over 6 mm, more than 33% bone loss, furcation involvement, tooth mobility) requires surgical intervention after non-surgical therapy if adequate pocket reduction is not achieved. Surgical options include open flap debridement, osseous surgery, guided tissue regeneration (GTR), bone grafting, and soft tissue grafts for recession. Periodontal treatment is also required before any implant placement, crown and bridge work, or orthodontic treatment to ensure a healthy periodontium. Patients with systemic risk factors — diabetes, smoking, immunosuppression — require intensified supportive therapy.

Non-surgical periodontic treatment begins with comprehensive charting of pocket depths, bleeding on probing, furcation involvement, tooth mobility, and radiographic bone levels. After local anaesthesia by quadrant, scaling and root planing (SRP) is performed using ultrasonic scalers and hand curettes to remove supragingival and subgingival calculus deposits and infected cementum, smoothing root surfaces to discourage bacterial reattachment. Re-evaluation at 6–8 weeks assesses treatment response. Residual pockets exceeding 5–6 mm after SRP are managed surgically. Periodontal flap surgery (modified Widman flap or resective surgery) reflects the gingival tissue to allow direct root instrumentation and surgical reshaping of the alveolar bone. Guided tissue regeneration uses resorbable barrier membranes and bone grafts (autogenous, allograft, or synthetic) to regenerate lost periodontal attachment. Free gingival grafts and connective tissue grafts address gingival recession and thin biotypes. Adjunctive locally delivered antibiotics (minocycline microspheres, chlorhexidine chips) may supplement SRP in Stage III–IV disease. Surgical periodontal treatment — periodontal flap surgery — involves raising a mucoperiosteal flap to access root surfaces and bone defects under direct vision. Osseous recontouring, debridement of infrabony defects, and placement of bone graft material or biologic agents (enamel matrix derivative — Emdogain) for guided tissue regeneration are performed where appropriate. Sutures are placed and the flap repositioned. Healing is assessed at 6–8 weeks and maintenance therapy initiated.

Scaling and root planing reduces probing depths by an average of 1–2 mm in Stage I–II periodontitis and achieves resolution of bleeding on probing in 60–70% of sites. Surgical periodontal therapy in Stage III–IV disease achieves additional pocket reduction of 1–2 mm compared with non-surgical treatment alone, and guided tissue regeneration produces clinical attachment gain of 2–4 mm with bone fill in 60–70% of treated infrabony defects. Regular supportive periodontal therapy (SPT) every 3–6 months reduces tooth loss by 50–70% compared with no maintenance. Successful periodontal treatment also reduces systemic inflammatory burden: HbA1c may improve by 0.4–0.5% in diabetic patients following periodontal therapy, demonstrating the systemic health benefits of gum disease management. Periodontal treatment halts disease progression in over 85% of patients with consistent maintenance therapy. Non-surgical scaling and root planing achieves an average probing depth reduction of 1–2 mm and attachment gain of 0.5–1 mm in moderate disease. Periodontal treatment also reduces systemic inflammatory markers (C-reactive protein, HbA1c in diabetics) and has been associated with improved glycaemic control, reduced cardiovascular risk markers, and better pregnancy outcomes in observational studies.

Scaling and root planing is safe with a very low risk profile. Temporary post-procedural discomfort, sensitivity to cold or sweet stimuli, and minor gingival bleeding lasting 24–48 hours are common. Root surface sensitivity from exposed cementum after calculus removal affects 30–40% of patients and is managed with desensitising toothpastes and fluoride varnish. Surgical periodontal treatment risks include infection (under 2%), swelling, post-operative pain, and temporary increase in tooth sensitivity or mobility. Recession after flap surgery may expose root surfaces, creating cosmetic concerns. Guided tissue regeneration membranes that become exposed to the oral cavity may require removal. Failure to comply with oral hygiene instruction and maintenance appointments significantly increases risk of disease recurrence and progressive tooth loss. Increased cold and sweet sensitivity following scaling and root planing resolves in most patients within 2–4 weeks. Root surface exposure (gum recession) may be cosmetically concerning and slightly increases root caries risk. Surgical procedures carry risks of post-operative swelling, bruising, bleeding, infection, and nerve injury if surgery is performed in the posterior mandible. Antibiotic use for resistant cases carries the risk of antibiotic resistance and gastrointestinal side effects.

After scaling and root planing, patients are advised to take over-the-counter analgesics for 24–48 hours. Soft diet is recommended for the first 24 hours. Chlorhexidine 0.12% mouthwash twice daily for 2 weeks supports healing and reduces bacterial load. Normal brushing of treated teeth may be resumed from day 2 with a soft toothbrush. Following periodontal surgery, sutures are placed and reviewed at 1–2 weeks for removal. Swelling peaks at 48 hours and resolves within 5–7 days. Ice packs are applied in the first 24 hours to reduce swelling. Post-surgical sensitivity improves over 4–8 weeks as the gingiva heals. Re-evaluation of the surgical outcome is performed at 3–6 months. Long-term supportive periodontal therapy every 3–6 months is essential to prevent disease recurrence and maintain attachment levels achieved by active treatment.
