When gums recede, the exposed root can become sensitive, catch decay, and make a tooth look longer than its neighbours. A gum graft is the surgical procedure that rebuilds the lost tissue and covers the exposed root. It sounds daunting, but it is a routine periodontal treatment with high success rates and a recovery most people find more manageable than they expect. This guide explains the main types, what recovery involves, typical costs, and how likely it is to work.
Key takeaways
- A gum graft adds tissue to areas where the gum has receded, covering exposed roots and thickening thin gum.
- The most common type, a connective tissue graft, takes a small amount of tissue from the palate and secures it over the recession.
- Reported success rates are high, generally above 90 percent for routine cases, with root coverage often better still for connective tissue grafts.
- Initial recovery usually takes one to two weeks, with full healing over several weeks to months.
- The graft holds long term when the cause of recession, such as heavy brushing or gum disease, is addressed.
The one rule: fix the cause, or the recession comes back
The most important point about gum grafting is that the graft treats the damage, not the reason it happened. If aggressive brushing, untreated gum disease, grinding, or a thin gum type caused the recession, those factors need to be managed as well. A beautifully placed graft over a tooth that is still being scrubbed with a hard brush will simply recede again. This is why a good assessment looks at why the gum receded in the first place. Our guide to gum recession causes and treatment covers the common drivers in detail.
What gum recession does, and when a graft is needed
Gum recession exposes the root surface, which has no protective enamel. That is why recession often shows up first as cold sensitivity or a notch near the gumline. Not every recession needs a graft. Mild recession that is stable and not causing symptoms can often be monitored. A graft is usually considered when recession is progressing, when the root is sensitive or at risk of decay, when there is very little firm gum left to protect the tooth, or when the appearance bothers the patient.
The main types of gum graft
| Type | How it works | Best for |
|---|---|---|
| Connective tissue graft | Tissue taken from under the surface of the palate and placed over the exposed root | The most common option, good root coverage for single or multiple teeth |
| Free gingival graft | A layer of surface tissue taken from the palate to thicken thin gum | Increasing the band of firm gum, often on lower front teeth |
| Pinhole or tunnel technique | Existing gum is loosened and eased down over the root through a tiny opening | Suitable cases where donor tissue or graft material is tunnelled with less cutting |
Which technique suits you depends on how much recession there is, how thick your gum is, and how many teeth are involved. A periodontist or dentist experienced in gum surgery will match the method to the situation.
What it costs
Gum grafting fees vary with the type of graft, the number of teeth treated, and who performs it. As a general guide across the market, a single site commonly falls somewhere in the range of about $600 to $3,000, with multiple sites treated together costing more overall but often less per tooth. These are general ranges to set expectations, not a quote from Lumi Dental. Because a graft is usually classified as major dental, most extras policies rebate part of the fee, often subject to an annual limit and any waiting period.
The team at Lumi Dental provides a written quote with item numbers after assessing your gums, so you can check your rebate before deciding. You can see how funds generally treat this kind of work in our guide to dental health insurance in Australia.
Recovery week by week
The first few days
Expect some swelling and tenderness, particularly at the palate if that is where the donor tissue came from. Most discomfort is managed with simple pain relief. Stick to cool, soft foods and avoid disturbing the graft site with your tongue, toothbrush, or hard food.
Days three to fourteen
Swelling settles and the graft begins to integrate. You will usually keep the surgical area clean with a prescribed rinse rather than brushing directly over it for a week or two. Many people return to work within a day or two, since the discomfort is more of a nuisance than a barrier.
Weeks to months
The graft continues to mature and blend with the surrounding gum over several weeks to months. Sensitivity at the treated tooth often improves as the root is covered. Your dentist will review healing and guide you back to normal brushing with a gentle technique.
How well do gum grafts work?
Success rates are reassuring. Reported figures generally sit above 90 percent for routine cases, and connective tissue grafts in particular achieve high average root coverage. Long term follow up shows grafted sites can retain coverage and reduced sensitivity for many years, provided the patient avoids smoking, manages any gum disease, and brushes gently. In other words, the procedure is reliable, and the main threat to a good result is a return of the original habit or condition that caused the recession.
Protecting the result
- Switch to a soft brush and light pressure. Scrubbing is a leading cause of recession and will undermine a graft.
- Keep your regular cleans. A routine scale and clean keeps the gumline healthy and lets your dentist catch early changes.
- Treat grinding. If you clench or grind, a night guard can reduce the forces that contribute to gumline damage.
- Address gum disease early. Bleeding when brushing is an early warning sign worth acting on, as covered in our article on bleeding gums.
Frequently asked questions
Is a gum graft painful?
Most people report the discomfort is milder than expected. The graft site itself is numb during surgery, and the palate donor area is usually the more tender spot afterwards. Simple pain relief manages it for most patients, and the worst tends to pass within a few days.
How long does a gum graft last?
When the cause of recession is managed, grafts can last many years, often for the long term. The main risks to longevity are continued heavy brushing, untreated gum disease, and smoking, all of which can lead to further recession.
Can I avoid a gum graft?
Mild, stable recession that is not causing symptoms can often be monitored rather than grafted, with attention to gentle brushing and gum health. A graft becomes worth considering when recession is progressing, the root is sensitive or at risk of decay, or there is very little firm gum left. Your dentist can advise which applies to you.
Where does the graft tissue come from?
Most commonly from the roof of your mouth (the palate), which heals over the following weeks. In some cases donated or laboratory processed tissue can be used instead, which avoids a second surgical site. Your dentist will discuss the options.
The takeaway
A gum graft is a dependable way to cover an exposed root, reduce sensitivity, and protect a tooth, with high success rates and a recovery most people handle comfortably. The key to a lasting result is fixing what caused the recession in the first place. If receding gums are bothering you, the team at Lumi Dental in Melrose Park can assess the area and talk through whether a graft or simple monitoring is the better path.
