Gum (Flap) Surgery: When It Is Needed and Recovery

Gum flap surgery is a periodontal procedure for deep gum pockets that deep cleaning alone cannot fix. The gum is gently lifted back so the roots and bone can be cleaned directly, then stitched back snugly around the teeth. It is done under local anaesthetic, and most people return to normal routines within a few days. For most patients with gum disease, deep cleaning brings the gums back under control. But when pockets are very deep, or the bone around the roots has an uneven shape, instruments working blind beneath the gum cannot reach every surface. Flap surgery gives the periodontist a direct view of the roots and bone, so the infection can be removed completely and the gum can heal tightly against the teeth.

When Is Flap Surgery Recommended?

It is usually considered after deep cleaning, at the re-evaluation visit, if some areas have not responded.

Pockets that remain deep (often 5 mm or more) after deep cleaning
Pockets that still bleed or produce pus
Bone defects around the roots that trap bacteria
Areas between the back teeth and root forks that are hard to clean
Where bone regeneration is planned along with the cleaning

What Happens During the Procedure

The area is numbed with local anaesthetic. The procedure is typically completed in a single sitting for each area being treated.

Small incisions allow the gum to be gently folded back
Tartar and infected tissue are removed from the roots and bone under direct vision, with magnification where helpful
The root surfaces are smoothed, and uneven bone edges may be reshaped so the gum can sit flat
In selected cases, bone graft material or PRF (made from your own blood) is placed to support regeneration
The gum is repositioned and stitched snugly around the teeth

Recovery: What to Expect

Some swelling and soreness for two to three days is common and is usually managed with the painkillers we recommend. Most people return to work within a day or two.

Eat soft, lukewarm food and chew on the other side for the first few days
Do not brush the surgical area until advised; use the prescribed mouthwash instead
Avoid smoking, which slows healing
Stitches are usually reviewed or removed after about one to two weeks
Call us if bleeding, swelling or pain increases rather than settles

Results and Long-Term Care

Once healed, pockets are shallower and much easier to keep clean. The gums may sit slightly lower than before, so some teeth can look a little longer and feel sensitive for a while. Long-term success depends on daily cleaning and regular periodontal maintenance visits.

Frequently Asked Questions

Is gum flap surgery painful?

It is done under local anaesthetic, so you should not feel pain during the procedure. Mild soreness and swelling for two to three days afterwards is common and manageable.

How long does gum surgery take to heal?

The gums usually feel comfortable within one to two weeks. Full healing of the tissues underneath takes a few months.

Can laser treatment replace flap surgery?

Sometimes. Laser gum therapy can treat some moderate pockets without incisions, but deep pockets and bone defects often still need surgical access. The choice depends on your examination.

Will I need surgery if I have gum disease?

Not necessarily. Many patients are treated with deep cleaning alone. Surgery is for areas that do not respond.

“

Flap surgery is a well-established way to treat the deep pockets that keep gum disease active. By cleaning the roots and bone directly, it gives the gums the best chance to heal tightly and stay healthy, protecting the teeth for the long term.
