How to Treat Periodontitis

Receiving a periodontitis diagnosis can feel overwhelming  especially when you learn that the bone loss and pocket formation have already occurred. But the clinical reality is far more encouraging than the initial diagnosis suggests. Periodontitis, even in moderate to severe stages, responds well to treatment when that treatment is delivered correctly, in the right sequence, and followed by a structured maintenance programme. The goal is not simply to suppress symptoms but to achieve genuine biological stability: gum tissue that is no longer actively infected, pockets that are reduced and maintainable, and bone levels that are no longer declining.

Step One: Accurate Diagnosis and Disease Staging

Effective treatment begins with precise diagnosis. A thorough periodontal assessment includes a full-mouth periodontal chart  six measurements per tooth recording pocket depth, bleeding on probing, furcation involvement, and tooth mobility  combined with radiographic bone level assessment. The 2018 classification system introduced by the American Academy of Periodontology stages periodontitis by severity (Stages I–IV) and grades it by rate of progression and systemic risk factors (Grades A, B, C). This staging directly determines the aggressiveness and complexity of the treatment protocol required.

Step Two: Patient Education and Risk Factor Modification

No professional intervention achieves lasting results if the patient's home care habits and modifiable risk factors are not addressed first. At this stage of treatment, your periodontist will review correct brushing and interdental cleaning techniques, identify and address risk factors including smoking, blood glucose control, medications that affect gum tissue, and stress, and establish realistic expectations for treatment outcomes based on your specific case.

This is not a formality. Studies consistently show that patients who achieve high plaque control scores before their definitive periodontal treatment respond significantly better than those with persistent poor hygiene. The bacteria you do not remove daily will re-infect any pocket the clinician decontaminates.

Step Three: Non-Surgical Periodontal Therapy (Scaling and Root Planing)

For most patients with periodontitis, the first active treatment phase is non-surgical: full-mouth scaling and root planing (SRP), also called subgingival debridement or deep cleaning. Under local anaesthesia  because this procedure accesses well below the visible gum line  the clinician uses hand instruments (curettes and scalers) and/or ultrasonic scalers to:

•        Remove all supra- and sub-gingival calculus deposits

•        Disrupt and mechanically remove the bacterial biofilm from root surfaces

•        Smooth the root surface (root planing) to make bacterial re-adhesion more difficult and facilitate soft tissue reattachment

Typically performed in two to four sessions per quadrant of the mouth, SRP produces significant clinical improvement in the majority of patients: probing depths reduce, bleeding on probing resolves, and in many cases, further surgical intervention becomes unnecessary. A re-evaluation is scheduled eight to twelve weeks after completing SRP to assess the tissue response before deciding on next steps.

Step Four: Surgical Periodontal Therapy (Where Indicated)

For sites that do not respond adequately to non-surgical treatment, typically residual pockets of 5mm or greater with continued bleeding, surgical intervention provides access to areas that instruments cannot reach effectively from above the gum line.

Periodontal Flap Surgery (Access Surgery / Osseous Surgery)

The gum tissue is reflected (folded back) under local anaesthesia to expose the root surfaces and underlying bone directly. This allows thorough debridement of remaining deposits, reshaping of any irregular bone defects (osseous contouring), and precise repositioning of the gum tissue to reduce pocket depth. The improved access achieves a level of decontamination that is impossible non-surgically in deep or anatomically complex sites.

Regenerative Procedures

In selected cases presenting with vertical bone defects  angular bone loss patterns where the bone has not been destroyed uniformly  guided tissue regeneration (GTR) using barrier membranes and bone grafting materials can be performed at the time of surgical access. These procedures aim to regenerate the lost periodontal attachment apparatus: bone, cementum, and periodontal ligament. Not every defect is suitable for regeneration; the position, morphology, and depth of the defect, as well as the patient's plaque control and smoking status, determine eligibility.

Laser-Assisted Periodontal Surgery

Laser technology  including the LANAP (Laser-Assisted New Attachment Procedure) protocol  offers a minimally invasive surgical alternative that decontaminates the pocket with laser energy rather than physical flap elevation. Laser surgery typically involves faster healing and less post-operative discomfort than conventional surgery, though it is not universally applicable to all defect types.

Step Five: Antimicrobial Adjuncts

In aggressive or generalised periodontitis cases, or in patients whose disease does not respond as expected to mechanical therapy alone, antimicrobial adjuncts may be incorporated:

•        Local drug delivery: Sustained-release antimicrobial agents (minocycline microspheres, chlorhexidine chips) placed directly into residual pockets after SRP reduce bacterial counts at resistant sites without systemic exposure.

•        Systemic antibiotics: Specific antibiotic combinations  most commonly amoxicillin and metronidazole  are used as adjuncts in generalised Stage III/IV or Grade C periodontitis, always in conjunction with mechanical debridement, never as a standalone treatment.

Step Six: Supportive Periodontal Therapy (Lifelong Maintenance)

Active treatment achieves disease control. Maintenance preserves it. Following the completion of active therapy, patients enter a structured supportive periodontal therapy (SPT) programme  typically recall appointments every three to four months for the first one to two years, adjusting to every four to six months based on demonstrated stability.

At each SPT appointment: the full-mouth periodontal chart is reassessed to detect any signs of recurrence early, professional cleaning removes newly accumulated plaque and calculus, motivational reinforcement and technique review maintain home care standards, and risk factor assessment tracks smoking status, systemic disease control, and stress levels.

Patients who adhere to formal SPT protocols lose significantly fewer teeth over five, ten, and twenty years than those who return to routine annual care after completing active treatment. Maintenance is not optional; it is the phase of treatment where the long-term outcome is actually determined.
