Inflammation and Immunity – Why Re-Creating Keratinised Gum Tissue Matters

The immune system is designed to respond to threats quickly. But when gums recede and the natural keratinised seal around the teeth is lost, bacteria and their toxins gain easier access to the body. The immune system is forced into constant battle, producing low-grade inflammation that contributes to cardiovascular disease, diabetes, arthritis, and autoimmune conditions.

Keratinised tissue plays a vital role in preventing this. Its firm, fibrous structure provides an effective seal, protecting underlying tissues from bacterial invasion. Restoring this barrier is therefore critical not only for dental stability but also for systemic health.

The Chao Pinhole Surgical Technique (PST) is uniquely suited to this goal. Instead of grafting donor tissue, PST repositions existing gum tissue over exposed roots, encouraging the development of new keratinised gingiva. This reseals the tooth-gum junction, blocking bacterial entry and reducing the inflammatory challenge to the immune system.

Evidence shows that PST produces stable root coverage and increases gingival thickness. Patients report faster healing, minimal discomfort, and long-lasting results. Most importantly, by recreating keratinised tissue, PST removes a constant source of immune activation. This allows the body to redirect energy towards maintaining balance and resilience rather than fighting off oral bacteria.

Takeaway: Gum recession compromises immunity by breaking the keratinised barrier. Pinhole surgery restores this tissue, reseals the leak, and reduces systemic inflammation — protecting both oral and general health.
