Gum grafting: what it is, how it works, and when it's necessary
Gum grafting is one of the most effective procedures for correcting gum recession , a condition in which the gums recede, exposing the root of the tooth.
It is a simple surgical procedure, performed under local anesthesia, which has two fundamental objectives:
-
protect the root of the tooth
-
restore fullness, thickness and aesthetic harmony of the gums
The procedure can improve oral health, prevent further damage, and restore a more balanced smile.
What is gum recession really?
Gum recession is a progressive process: the gum thins, loses its hold and retreats from its original position.
This exposes the root of the tooth, a much more sensitive and vulnerable part than the enamel.
According to sources, the main factors are:
-
poor oral hygiene
-
plaque and tartar buildup
-
brushing too aggressively
-
smoke
-
genetic predisposition
-
diabetes
-
mechanical trauma
-
vitamin C deficiency
When ignored, it can lead to:
-
root caries
-
gum inflammation
-
tooth instability
-
tooth loss
It is a condition that should not be underestimated.
What is gum grafting?
Gum grafting involves taking a small amount of healthy tissue from another area of the mouth—usually the roof of the mouth—to rebuild healthy, strong, and sufficiently thick gum tissue where it has receded.
In other words, it is an intervention that:
-
increases the thickness of the gum
-
covers exposed roots
-
strengthens the gums to prevent new recessions
-
aesthetically improves the smile
The operation is performed under local anesthesia , is short and painless, with a very high success rate when performed by an experienced periodontist.
How the procedure works: the procedure explained
Gum grafting follows a standard 3-step procedure:
1. Tissue collection (donor site)
The periodontist takes a small portion of tissue from the palate or another suitable area.
The main techniques are:
-
connective tissue sampling → the most used, excellent aesthetic results
-
epithelial-connective tissue sampling → ideal if the palatal thickness is reduced
-
free gum graft → to increase keratinized tissue
-
pedunculated graft → uses the surrounding gum without taking it from the palate
The choice depends on the type of recession, the thickness of the gum and the amount of tissue needed.
2. Tissue insertion (recipient site)
The tissue is precisely adapted and sutured into the retracted area.
The new fabric:
-
increases the thickness
-
covers the root
-
creates a barrier against bacteria
-
stabilizes the gum margin
3. Protection and healing
The flap is protected and fixed. Healing is rapid: the gum begins to integrate within the first 48–72 hours.
Techniques explained simply
Connective tissue graft
Sampling of only the internal tissue of the palate.
Excellent aesthetics, rapid recovery. It's the most modern and widely used technique.
Epithelial-connective tissue graft
Complete sampling, then removal of the epithelium.
Excellent option if the palatal thickness is reduced (< 2.5 mm).
Free gum graft
Epithelial tissue is taken directly from the palate.
Perfect when you need to increase the size of keratinized gums.
Grafting on implants
When gum tissue is missing around an implant, the graft increases the thickness and improves the protection of the implant itself, reducing the risk of peri-implantitis.
When is gum grafting necessary?
Grafting is recommended in cases where:
-
the root is exposed
-
the recession continues to worsen
-
the gum is too thin to protect the tooth
-
the sensitivity is strong or disabling
-
an implant needs to be placed
-
there is an obvious aesthetic problem
-
recession threatens the stability of the tooth
In many cases, the intervention prevents much more serious future problems.
Is it a painful procedure?
During the procedure: no , zero pain. The area is locally anesthetized.
After the surgery:
-
slight discomfort
-
swelling in the first 48 hours
-
feeling of tension in the gums
Everything can be managed with:
-
ibuprofen
-
paracetamol
-
ice packs with a soft cloth
Diet after gum grafting
For 7–10 days it is recommended to eat the following foods:
Healing times
Healing occurs in several phases:
-
48–72 hours → start of tissue integration
-
1–2 weeks → initial healing
-
2–4 weeks → complete recovery
-
2–4 months → total consolidation (depending on extension and technique)
The donor site (palate) often heals more slowly than the recipient site, but without complications.
FAQ
Does gum grafting hurt?
No. The procedure is painless thanks to local anesthesia. You may experience some mild post-operative discomfort, which can be managed with painkillers.
How long does recovery take after a gum graft?
Initial healing occurs in 1–2 weeks.
Complete healing in 2–4 weeks.
Where is the tissue for the graft taken from?
In most cases, it's from the palate. Alternatively, pedunculated techniques or synthetic grafts are used.
When is it necessary to do a graft?
When recession exposes the root, it causes sensitivity, worsens over time, or compromises aesthetics.
Can I eat normally after the transplant?
Yes, but only soft and cold foods for 7–10 days. Avoid hot, hard, spicy foods, and alcohol.
Is gum grafting permanent?
The results are stable over time, provided you maintain good oral hygiene and have regular check-ups.
CONCLUSIONS
Gum grafting is one of the most effective procedures in modern periodontology: it protects the roots, strengthens the gums, improves the smile and reduces the risk of future problems.
It is a minimally invasive procedure, with rapid recovery times and highly predictable results.
Especially when gum recession continues to worsen, early intervention can save teeth, aesthetics, and oral health in the long term.
