Advanced gum disease with bone loss around the teeth. Can lead to mobility, bleeding, and eventual tooth loss if untreated.
What typically happens with each treatment choice over time, based on clinical evidence — not individual cases.
Continued bone loss and increasing tooth mobility.
What it means: Progressive tooth loss likely.
Active disease arrested with pocket-depth reduction in most patients.
What it means: Most teeth retained with regular maintenance.
Regeneration or stabilization of bone levels.
What it means: Improved long-term retention vs non-surgical alone.
Public outcomes are shown only where the direction is supported by high-tier evidence — Cochrane systematic reviews, randomized controlled trials, and meta-analyses. We report the untreated ("do nothing") branch alongside active treatment. Each figure is an evidence-informed, directional estimate consistent with the peer-reviewed literature and professional-body guidance (Cochrane Oral Health, ADA, AAE, AAP, AAOMS) — not a number quoted from one specific study — and is reviewed by our Benchmark Council. Estimates are population-level and may not apply to your individual case.
