Advanced gum disease, clinically known as periodontitis, occurs when chronic inflammation causes the gums to pull away from the teeth, creating deep pockets where bacteria thrive and eventually destroy the supporting bone. Unlike gingivitis, the bone loss associated with periodontitis is irreversible; however, the disease can be stabilised through intensive clinical interventions. Treatment focuses on cleaning the deep root surfaces to eliminate infection, reducing pocket depths, and in some cases, attempting to regenerate lost tissue to prevent further tooth loss.

Root Surface Debridement and Deep Cleaning
The first line of treatment for advanced gum disease is root surface debridement (RSD), often referred to as deep cleaning or root planning. This procedure involves thoroughly cleaning the root surfaces of the teeth below the gum line to remove plaque, tartar, and bacterial toxins that have accumulated in the periodontal pockets. Because this involves working deep within the gum tissues, the procedure is typically performed under local anaesthetic to ensure patient comfort.
The goal of RSD is to create a clean, smooth root surface that allows the gum tissue to reattach to the tooth or at least shrink, thereby reducing the depth of the pockets. The NHS states that if gum disease has progressed to periodontitis, deep cleaning is a necessary clinical step to stop the infection from further destroying the bone. Following this treatment, patients must maintain exceptionally high standards of home care to prevent bacteria from recolonising the newly cleaned areas.
Periodontal Flap Surgery
When deep cleaning is insufficient to reduce periodontal pockets, a dentist or periodontist may recommend flap surgery. During this procedure, the gum tissue is surgically lifted back to provide direct visibility and access to the roots and the underlying bone. This allows for a much more thorough removal of bacterial deposits that are otherwise unreachable.
Once the area is cleaned, the gum tissue is repositioned and sutured back into place, often more snugly around the tooth to reduce the pocket depth. By making the areas easier to clean for the patient, surgery significantly lowers the risk of future bone destruction. Guidance from NICE and the British Society of Periodontology supports the use of surgical interventions when non-surgical treatments have failed to stabilise the disease.
Bone Grafts and Tissue Regeneration
In cases where significant bone loss has occurred, regenerative procedures may be used to try and rebuild some of the lost support. Bone grafting involves placing natural or synthetic bone material into the areas where the jawbone has dissolved. This graft serves as a scaffold, encouraging the body’s own bone cells to grow and replace the damaged area.
Guided tissue regeneration (GTR) is another advanced technique often used alongside grafting. It involves placing a small piece of mesh-like fabric between the bone and gum tissue to prevent the faster-growing gums from filling the space where the slower-growing bone should be. This allows the bone and connective tissue to regenerate properly. While these treatments cannot restore the mouth to its original state, they can significantly improve the stability of the remaining teeth.
Use of Antibiotics in Periodontal Therapy
Antibiotics may be prescribed as an adjunct to mechanical cleaning, particularly in cases of aggressive periodontitis or persistent infection. These may be delivered as a systemic oral medication or applied locally as antimicrobial gels or chips placed directly into the periodontal pockets. Local delivery allows for a high concentration of the drug to reach the site of the infection with minimal systemic side effects.
However, antibiotics are never used as a standalone treatment for advanced gum disease. The physical biofilm (plaque) must be mechanically disrupted through scaling or surgery for the antibiotics to be effective. Over-reliance on antibiotics without proper mechanical cleaning can lead to bacterial resistance and failure to resolve the underlying bone loss.
Comparison of Advanced Treatment Modalities
| Treatment Stage | Clinical Method | Primary Objective | Typical Recovery |
| Non-Surgical (RSD) | Deep scaling under anaesthesia | Remove sub-gingival bacteria | 2 to 5 days |
| Surgical (Flap) | Incision and root debridement | Reduce pocket depth | 7 to 14 days |
| Regenerative | Bone grafting and membranes | Rebuild supporting structures | Several months |
| Supportive Care | Frequent reviews and cleaning | Prevent disease recurrence | Ongoing |
Supportive Periodontal Therapy (Maintenance)
Once advanced gum disease is stabilised, the patient enters a lifelong phase of supportive periodontal therapy. Because individuals who have experienced bone loss remain highly susceptible to further infection, regular maintenance appointments usually every three to four months are required. During these visits, the dental team monitors pocket depths and performs targeted cleaning to manage any new bacterial activity.
This maintenance is just as important as the initial treatment. Without it, the disease is likely to return, leading to further bone loss and eventual tooth loss. Public health toolkits emphasize that long-term success in managing periodontitis depends on the combination of professional maintenance and the patient’s commitment to daily interdental cleaning.
Conclusion
Advanced gum disease with bone loss requires intensive clinical management to save the natural teeth. Through a combination of root surface debridement, surgical interventions, and regenerative techniques, the progression of the disease can be halted. While the bone loss itself is largely permanent, stabilising the condition ensures that the remaining support is preserved. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Can lost bone around teeth ever grow back on its own?
No, jawbone destroyed by gum disease cannot regenerate on its own; it requires advanced clinical procedures like bone grafting to encourage new growth.
Is flap surgery painful?
The surgery is performed under local anaesthesia, so you will not feel pain during the procedure. There may be some discomfort and swelling for a few days afterward, which can usually be managed with standard painkillers.
Will my teeth feel loose after deep cleaning?
It is common for teeth to feel slightly more mobile initially as the inflamed, swollen gum tissue shrinks back, but as the tissues heal and tighten, stability typically improves.
What happens if I choose not to treat advanced gum disease?
Untreated periodontitis will continue to destroy the bone, eventually leading to teeth becoming so loose that they either fall out or must be extracted by a dentist.
Are regenerative treatments available on the NHS?
Basic periodontal treatments are available, but complex regenerative surgeries or bone grafts are often considered specialist procedures and may have limited availability depending on clinical criteria.
Can I still have dental implants if I have had bone loss?
Implants require a certain volume of healthy bone to be successful; if bone loss is severe, you may need a bone graft before an implant can be considered.
How do I clean my teeth after gum surgery?
Your dentist will provide specific instructions, which may include using a soft toothbrush and an antiseptic mouthwash for the first week while the stitches are in place.
