Periodontal Flap Surgery for Advanced Gum Disease: What to Expect

Esthetica International Clinique · Gurugram & Malviya Nagar, Delhi · Updated 2026-10-13

Advanced gum disease, also called periodontitis, does not always get better with brushing, flossing, or even a routine cleaning. When the infection has gone deep under the gums and started affecting the bone around the teeth, a procedure called periodontal flap surgery is often recommended. This article explains what it is, when it becomes necessary, how it is performed, and what recovery looks like, so you can make an informed decision with your dentist.

What Is Advanced Gum Disease?

Gum disease begins as gingivitis, with red, swollen, or bleeding gums. If untreated, it progresses to periodontitis, where the infection damages the fibres and bone that hold your teeth in place. This creates deep pockets between the gum and tooth where bacteria and tartar collect, out of reach of a toothbrush or regular floss. Over time, this can lead to loose teeth, gum recession, bad breath, and eventually tooth loss if not managed.

When Is Flap Surgery Needed?

Most cases of gum disease are first treated with non-surgical methods such as scaling and root planing (deep cleaning below the gumline). Flap surgery is usually considered when:

• Gum pockets remain deep (often more than 5-6 mm) even after deep cleaning
• There is visible bone loss on X-rays around one or more teeth
• Infection and inflammation persist despite good home care
• Access is needed to thoroughly clean tartar from deep pockets or furcation areas (where tooth roots split)
• Bone or tissue regeneration procedures are planned alongside cleaning

Your dentist will usually recommend this only after reassessing your gums a few weeks following initial deep cleaning, to see how well they have healed.

How Periodontal Flap Surgery Works

The procedure is done under local anaesthesia, so you remain awake but should not feel pain.

1. The gum tissue is gently lifted back (like a flap) to expose the tooth roots and underlying bone
2. Tartar, bacteria, and infected tissue are thoroughly removed from the roots and pockets
3. If needed, uneven or damaged bone is smoothed, or bone graft material may be placed to support regeneration
4. The gum tissue is repositioned snugly against the tooth and bone, and stitched (sutured) into place

The surgery usually takes between 45 minutes to a couple of hours, depending on how many teeth and areas are involved. It may be done in one or more sittings.

What Recovery Involves

Recovery from periodontal flap surgery is generally straightforward if post-operative instructions are followed carefully.

First Few Days

• Mild swelling, soreness, and slight bleeding are common and usually settle within 2-3 days
• Pain relievers and sometimes antibiotics are prescribed
• A cold compress on the cheek can help reduce swelling
• Soft, cool foods are recommended, avoiding hot, spicy, or hard foods near the surgical site

First Two Weeks

• Stitches are typically removed after 7 to 10 days if non-dissolving sutures were used
• Gentle brushing is resumed as advised, usually avoiding the surgical area initially and using a prescribed antiseptic mouth rinse
• Smoking should be avoided completely, as it significantly slows healing and reduces success rates

Long Term

Once healed, gums usually sit slightly lower on the teeth than before, which can occasionally make teeth look a bit longer. This is a normal part of healing as inflammation and pocket depth reduce. Long-term success depends heavily on maintaining good oral hygiene and attending regular supportive cleanings, usually every 3 to 4 months initially.

Typical Cost Range

Costs for periodontal flap surgery vary based on the number of teeth involved, complexity, and whether bone grafting is required. In Gurugram and Malviya Nagar, Delhi, the typical range per quadrant (a section of the mouth) is approximately Rs 8,000 to Rs 20,000, with full-mouth treatment costing more. Your dentist will give you a detailed estimate after an examination and X-rays, since actual pricing depends on your specific condition.

Is Flap Surgery Right for You?

Not every patient with gum disease needs surgery. Your dentist will assess pocket depths, bone levels on X-rays, your response to initial treatment, and your overall health (including conditions like diabetes that affect healing) before recommending this option. If you have been told you have advanced gum disease and deep pockets that are not improving, it is worth discussing whether flap surgery could help preserve your teeth and gum health for the long term.
