Osseous Surgery: When It’s Necessary & What to Expect

Maintaining oral health is crucial for overall well-being, yet many people face challenges with gum disease, a bacterial infection of the gums and teeth-supporting tissues. Among the various treatments available, osseous surgery stands out as a critical intervention for those suffering from advanced stages of periodontal disease. This procedure, also known as pocket reduction surgery or flap surgery, is designed to address severe gum issues that cannot be managed with routine dental care alone. In this blog post, we will discuss what is osseous surgery, exploring its purpose, the step-by-step procedure, and the vital role it plays in treating advanced gum disease.

What is Osseous Surgery?

Osseous surgery, also known as pocket reduction surgery or gum flap surgery, is a specialized periodontal surgery aimed at treating moderate to severe periodontitis, an advanced stage of periodontal disease. In a healthy mouth, the gums fit snugly around the natural teeth, forming a seal that keeps bacteria and food debris from entering. The normal space between the gums and teeth, known as the sulcus, measures 1-3 millimeters in depth.

When periodontitis develops, the gums begin to pull away from the teeth, increasing the depth of the space between the gum and tooth and creating periodontal pockets. These gum pockets can become deeper due to inflammation or the destruction of the bone structure that supports the teeth. Periodontal pockets provide an ideal environment for harmful bacteria to thrive because they are difficult to clean with regular brushing and flossing.

Osseous surgery is indicated when the depth of periodontal pockets exceeds 5 mm. The primary goals of this surgery are to reduce the pocket size, eliminate the infection, and restore oral health. By addressing these deep pockets and the associated oral bacteria, osseous surgery helps preserve the damaged bone and support the teeth, effectively combating advanced gum disease and promoting a healthier mouth.

When is Osseous Surgery Nessassery?

Periodontal disease, also known as gum disease, is a bacterial infection of the gums and teeth-supporting tissues. It is categorized into two stages: gingivitis and periodontitis.

Gingivitis, a mild gum disease, is characterized by inflammation, redness, and bleeding of the gums. With professional cleaning and improved oral hygiene habits, this early stage of gum disease can often be reversed. However, if left untreated, gingivitis can progress to periodontitis, a more advanced and destructive form of gum disease.

Periodontitis, a severe gum disease, leads to jawbone destruction, gum recession, and the formation of deep gum pockets around the teeth roots. These deep pockets harbor harmful bacteria, making it difficult to maintain oral health through routine brushing and flossing. Without intervention, periodontitis can become severe, resulting in significant bone loss and potentially tooth loss. Moreover, advanced gum disease has been linked to other systemic health issues, such as cardiovascular disease.

To combat these issues, a periodontal specialist may recommend osseous surgery. This procedure not only reduces pocket size but also helps eliminate the infection and preserve the jawbone. By addressing the root cause of the infection and improving dental pocket size, osseous surgery plays a vital role in restoring oral health and preventing further complications.

Benefits of Osseous Surgery

Osseous surgery can have many benefits for patients suffering from moderate to severe periodontitis, an advanced periodontal disease. This type of surgery can help restore gum health, reduce infected gum pocket depths, and improve the aesthetics of your smile.

Additionally, osseous surgery helps reduce harmful bacteria in the mouth, which can lower your risk of developing other diseases caused by oral bacteria.

If you are considering osseous surgery, your dentist or periodontist will be able to answer any questions you may have and help you decide if this type of treatment is right for you.

How is the Osseous Surgery Procedure Performed?

Osseous surgery, or pocket reduction surgery, is a specialized gum disease treatment performed under local anesthesia by a periodontist, a dental specialist trained in managing advanced gum disease. The pocket reduction surgery procedure starts with an incision in the gum to create a flap, exposing the underlying bone and the tooth roots.

The periodontist then performs scaling and root planing, a deep cleaning process to remove harmful bacteria, dental plaque, and tartar from the surfaces of the teeth and roots. This step also involves smoothing rough spots on the roots to prevent bacterial accumulation and encourage the reattachment of the gums to the teeth.

Next, the periodontist reshapes the bone structures. Using instruments such as curettes, bone scrapers, or lasers, they smooth out damaged or irregularly shaped bone around the teeth. This helps create a smooth surface for the gums to reattach securely and form a tight seal. In cases of significant bone loss due to periodontitis, bone grafting may be necessary. The periodontist will use bone graft materials to replace lost bone, supporting the natural teeth and enhancing overall bone structure.

Once the bone reshaping or grafting is complete, the gums are repositioned and sutured back into place to facilitate healing. The recovery period for osseous surgery typically spans several weeks.

During the healing period, patients must follow their periodontist’s post-operative care instructions closely to ensure proper healing and avoid complications. These instructions may include dietary modifications and oral hygiene practices.

If you take blood-thinning medications, inform your periodontist prior to the procedure, as these medications can increase the risk of bleeding during and after the surgery, and your periodontist may need to adjust your medication or take special precautions to ensure your safety.

The Periodontal Surgery Step-by-Step

During osseous surgery, here’s what you can expect:

  • Anesthesia: The periodontal surgery is performed under local anesthesia to ensure your comfort throughout the procedure.
  • Incision: The periodontist will make an incision in the gums to create a flap, exposing the underlying bone structure and tooth roots.
  • Deep Cleaning: The periodontist will perform scaling and root planing, a deep cleaning procedure to remove harmful bacteria, plaque, and tartar from the tooth roots.
  • Bone Smoothing: Damaged or irregularly shaped bone will be smoothed using instruments such as curettes, bone scrapers, and lasers to create a conducive environment for gum reattachment.
  • Bone Grafting: In severe cases, bone graft materials may be placed to build up areas of bone that have been damaged, supporting the natural teeth and enhancing bone structure.
  • Gum Repositioning: The gums will then be repositioned and sutured back into place to promote proper healing and form a tight seal around the teeth.
  • Post-Operative Care: Post-operative instructions will be provided, including guidelines on oral hygiene, dietary restrictions, and specific medications to take to manage pain and prevent infection.

What to Expect After the Osseous Surgery?

Following osseous surgery, patients can expect some postoperative pain, which is typically managed with prescribed pain medications. Swelling and minor bleeding are also normal postoperative side effects and should resolve within a few days.

During the initial recovery period, it is common to experience tooth sensitivity, especially to hot and cold temperatures. This sensitivity is due to the exposure of tooth roots during the periodontal surgery and should gradually diminish as the gums heal.

In some cases, patients might notice that their teeth feel slightly loose after the deep cleaning and reshaping of the bone. This sensation usually subsides as the gums reattach and stabilize around the teeth.

To manage postoperative pain effectively, follow your periodontist’s aftercare instructions closely. Maintaining excellent oral hygiene is crucial, but be gentle around the treated areas to avoid disturbing the healing process.

While experiencing pain after teeth cleaning is common, the level of discomfort should steadily decrease. If severe pain or excessive bleeding persists, contact your dentist or periodontist promptly for further evaluation and care. Overall, with proper pain management and adherence to postoperative care instructions, recovery from osseous surgery can be smooth, leading to improved oral health.

Aftercare Instructions

During the recovery period after osseous surgery, patients may find it difficult to eat and drink comfortably. It is crucial to follow your dentist or periodontist’s aftercare instructions closely to ensure a smooth recovery and a high success rate. Here are some aftercare instructions to help relieve pain after teeth cleaning and periodontal surgery.

  • Pain management: Take the prescribed pain medications to manage postoperative pain and swelling.
  • Cold compress: Apply an ice pack to your face, over the surgical area, during the first 24 hours after surgery to reduce swelling.
  • Diet: Eat soft foods for the first few days following surgery to avoid irritating the surgical site.
  • Smoking: Avoid smoking, as it can delay healing and increase the risk of post-surgical infections.
  • Physical activity: Avoid physical activity for the first few days after your periodontal surgery to allow your body to heal.
  • Straws and spitting: Avoid drinking from straws or spitting forcefully, as this may disrupt the healing process and increase the risk of dislodging blood clots.
  • Oral hygiene: Practice good oral hygiene to promote healing and prevent infection-causing bacteria. Use a soft-bristled toothbrush and gently brush your teeth twice daily.
  • Mouth rinsing: Rinse with warm salt water and an antibacterial mouthwash after 24 hours to reduce the risk of infection and aid in the healing process.
  • Follow-up appointments: Keep follow-up appointments with your dentist or periodontist for checkups to ensure the surgery was successful and to monitor for any complications.

Adhering to these aftercare instructions not only helps in managing discomfort and preventing infections but also significantly enhances your overall dental health following periodontal surgery.

Do I Need Osseous Surgery?

You may need osseous surgery if your dentist or periodontist finds that you have advanced periodontitis that has caused severe damage to the tooth-supporting bone and tissues. However, osseous surgery is just one of several possible gum disease treatments.


Other dental procedures may be sufficient depending on the severity of your condition. Your periodontist will be able to assess your needs and recommend a suitable treatment, including:

  • Scaling and root planing: This non-surgical procedure removes plaque buildup and smooths the surface of your teeth roots, making it harder for infection-causing bacteria to re-colonize.
  • Antibiotic therapy: Your periodontist may recommend antibiotics in combination with scaling and root planing to eliminate the infection.
  • Soft-tissue grafts: If you have receding gums, your periodontist may recommend a soft tissue graft to cover exposed roots and restore gum tissue, helping to shrink gum pockets.
  • Guided tissue regeneration: In cases of severe bone loss, your periodontist may suggest regenerative techniques that stimulate your body’s own healing process to regrow healthy bone and tissue.
  • Tooth extraction: If your teeth are too severely damaged to be saved, the periodontist may recommend extracting them and replacing them with dental implants.

Choosing the right treatment is essential to manage gum disease effectively and maintain your dental health. Your periodontist will work with you to develop a personalized treatment plan to get your periodontal disease under control and preserve your smile.

Prevention of Periodontal Disease

Preventing periodontal disease starts with excellent home care and consistent oral hygiene practices. Brushing your teeth at least twice a day with fluoride toothpaste helps to remove food particles and plaque, which can lead to gum inflammation. Flossing daily is also crucial, as it cleans the areas between your teeth that a toothbrush can’t reach, preventing the buildup of tartar and dental pockets. Incorporating an antibacterial mouthwash into your oral care routine can further reduce bacteria in the mouth and support gum health.

Additionally, a balanced diet rich in vitamins and minerals strengthens your immune system, helping your body fight off infections and maintain overall dental health.

Regular visits to dental professionals are vital for maintaining periodontal care. A dental hygienist can provide thorough dental cleanings to remove plaque and tartar, breaking tartar off teeth before it leads to more serious issues.

During these visits, your dentist can also assess your gum health and recommend treatments if necessary. If periodontal disease is detected early, non-surgical interventions like scaling and root planing might be sufficient. However, in more advanced cases, periodontal surgery, such as pocket reduction surgery, may be required. By following your dental care provider’s advice and maintaining diligent home care, you can significantly reduce your risk of developing periodontal disease and maintain optimal oral health.


When periodontitis develops, the gums begin to pull away from the teeth, increasing the depth of the spaces between the teeth and gums and creating periodontal pockets. These gum pockets provide an ideal environment for bacteria to thrive because they are difficult to clean. If left untreated, periodontitis can lead to significant bone loss and ultimately result in tooth loss.

Osseous surgery, also known as pocket reduction surgery, is an effective treatment for moderate to severe periodontitis where the depth of periodontal pockets exceeds 5 millimeters. The procedure involves smoothing the damaged or irregularly shaped bone surrounding the affected teeth to reduce the pockets and eliminate areas where bacteria can accumulate. This promotes healing, eliminates infection, and restores periodontal health, helping to preserve the teeth and improve overall dental health.

By addressing the deep pockets and supporting bone structures, osseous surgery plays a crucial role in managing advanced periodontal disease and preventing further complications. If you are experiencing symptoms of periodontitis, consult with your dentist or periodontist to determine the best treatment plan for restoring and maintaining your oral health.
