Periodontal Surgery in Hong Kong: When Gum Bleeding Signals Advanced Disease

If deep gum pockets over 5mm and bleeding gums persist after root debridement, open-flap or regenerative periodontal surgery may be the next step.

For patients with moderate to severe periodontal disease, or after deep root debridement, there are still deep periodontal pockets of more than 5 mm and accompanied by bleeding gums, they should consider another way to treat periodontal disease. When the deep part of the periodontal pocket cannot be completely removed by mean of root debridement, open-flap debridement is required. This operation is the most common periodontal surgery. After turning over the gum under local anesthesia, the calculus and inflamed tissue on the surface of the tooth root are more thoroughly removed under the condition of direct vision, and then the wound is sutured. Periodontal surgery results in better access to furcations, complex root surfaces, and infrabony pockets (those apical to the crest of bone, surrounded by bone on one or more sides), areas that are the most difficult to treat by scaling and root planing. Surgery is not the starting point: the non-surgical stage is completed first and often resolves the disease.

If clinical conditions allow, artificial bone material and/or regeneration membranes and other biological materials can be implanted in the part of the bone defect when the gum is opened, thereby inducing the regeneration of periodontal cells, repairing the previously damaged alveolar bone, and restore the function of teeth. This kind of surgery is called regeneration surgery. The purpose of the surgery is to promote the regeneration of alveolar bone. Compared with only performing debridement, a better treatment result can usually be obtained. However, it should be noted that not all bone defects can be repaired. Whether the shape of the bone defect is properly placed with regenerative materials is a factor that affects the possibility and effect of regenerative surgery.

However, if the bone around the teeth has been severely damaged and the periodontal tissue has been lost, there is no guarantee that those teeth that have serious problems will never fall out after the periodontal treatment is completed. Sometimes, the doctor may suggest that the patient remove the affected tooth in order to avoid further damage to the surrounding tissues. Considering the success rate of the operation and the predicted lifespan of the tooth, tooth removal may be a more recommended option. Bleeding gums are a late warning, and how the disease reaches the advanced stage shows what precedes it.

When the treatment is completed, the doctor will determine whether the patient can enter the maintenance phrase. Depending on the condition of each patient, the doctor will set the time for the patient's follow-up. The follow-up appointment is usually within three months after the completion of the treatment. After the condition is stable, the follow-up may be changed to every six months or one year. And when the periodontal health is satisfactory, if the patient wants to repair the appearance of the gum, the doctor can then evaluate the possibility of gum repair.

FAQ

Frequently Asked Questions

  • What is open-flap debridement and when is it needed?

    Open-flap debridement is the most common periodontal surgery, performed when deep periodontal pockets (over 5 mm) with bleeding gums persist after initial treatment. Under local anaesthetic, the gum is lifted to allow direct access to remove calculus and inflamed tissue from the tooth root, then sutured closed. It's recommended when scaling and root planing cannot reach complex areas like furcations and infrabony pockets.

  • How much does periodontal surgery cost?

    The cost of periodontal surgery depends on the extent of disease, number of teeth involved, and whether regenerative materials are needed. Pricing varies by case complexity and is determined after clinical assessment. Price differences reflect the treatment scope and who performs it (hygienist, general dentist, or a dentist with advanced periodontal training); how thoroughly subgingival deposits are removed determines whether the condition recurs. After a clinical assessment we explain the fee components clearly, and treatment starts only with your consent. WhatsApp us to arrange a consultation where we can provide a personalised quote based on your specific periodontal condition.

  • What is regeneration surgery and how does it work?

    Regeneration surgery involves placing artificial bone material and regeneration membranes into bone defects during open-flap surgery. These biological materials induce periodontal cell regeneration, helping repair damaged alveolar bone and restore tooth function. This approach typically achieves better outcomes than debridement alone, though success depends on the shape and location of the bone defect.

  • Will my teeth definitely be saved after periodontal surgery?

    There is no guarantee that severely compromised teeth will never fall out after treatment, even with surgery. If bone around the teeth has been severely damaged and periodontal tissue extensively lost, your dentist may recommend extraction to prevent further damage to surrounding tissues. The decision considers the surgery's success rate and the tooth's predicted lifespan.

  • How long does recovery take and what follow-up is needed?

    After periodontal surgery, your first follow-up is typically within three months of completing treatment. Once your condition stabilises, follow-ups may be scheduled every six months or annually. The maintenance schedule depends on your individual periodontal health. When gum health is satisfactory, gum repair for aesthetic purposes can be evaluated.

  • Are there any risks or complications with periodontal surgery?

    As with any surgical procedure, periodontal surgery carries some risks. Not all bone defects can be successfully repaired, and the shape of the defect affects regenerative outcomes. In cases of severe bone damage, teeth may still be lost despite treatment. Your dentist will assess your specific situation and discuss realistic expectations during your consultation.
