What will happen when I come in about gum grafting?

What the consultation is for

A gum graft consultation is a fact-finding visit. Treatment is not usually done at the same visit. Its job is to answer three questions: how much gum has been lost around each tooth, why it happened, and whether the area is better watched or treated. Gum recession means the gum edge has pulled back from the crown of the tooth and exposed part of the root. Because the root surface is softer than enamel and is not meant to be exposed, recession can lead to sensitivity, root decay and wear, and in some people it keeps progressing. Grafting aims to cover the exposed root, help prevent further recession and bone loss, reduce sensitivity and improve appearance, but not every area of recession needs it. The consultation sorts out which situation you are in.

What to bring

• Previous X-rays and gum measurements. If a former dentist recorded periodontal charting, those numbers show whether the recession is new or has been stable for years. Ask your previous office to send them ahead of time.
• Your medication list and health history. Medications that affect bleeding, diabetes, smoking and some other conditions may change the plan. Bring the list even if you think nothing is relevant.
• Your orthodontic history. Past braces or aligners, and whether you still wear a retainer, matter because moving teeth can shift roots relative to the bone that covers them.
• Your toothbrush, or a note of what you use. Brush type and brushing pattern are part of the cause-finding.
• Older photographs of your smile. A clear photo from a few years ago can show whether the gum line has moved.
• Your questions. The worksheet below gives you a place to write them.

If this is also your first visit to the practice, the guide on your first visit covers the general paperwork and what a check-up includes.

What is measured and why

Recession depth and the state of the root

For each affected tooth, the dentist measures how far the gum edge sits below the line where enamel meets root. That number is the recession depth, and it is the figure later visits will be compared against. The root surface itself is checked for softness, notches worn into it, decay and sensitivity to air or a light touch. Exposed roots are covered by cementum, a softer tissue than enamel, so they are more vulnerable to decay, and sensitivity is one of the common complaints that brings people in.

The gum around the recession

A periodontal probe measures the depth of the groove between gum and tooth and how much firm, attached gum tissue remains below the recession. How much of this tissue is left is part of judging the risk of further recession, and it influences which grafting technique may be suggested, since gaining firm tissue is one of the things grafts are measured on. The small triangles of gum between the teeth, called papillae, are examined too, because their height is part of the planning for any graft.

Bone and tooth position

X-rays show the level of bone around the roots and problems below the gum line that cannot be seen directly. The dentist also looks at where each root sits in the jaw. A root positioned toward the outside of the bone, whether naturally or after tooth movement, has less bone and gum covering it, and that is a frequent setting for recession.

The likely cause

Recession usually has more than one contributing factor, and the plan depends on which ones apply to you:

• Gum disease. Periodontal disease is among the most common causes. Bacteria and inflammation destroy the fibers and bone that hold the gum in place, and the gum pulls away from the tooth. If disease is active, ask whether it needs to be controlled before any graft is considered.
• Brushing forces. Scrubbing hard, especially with a stiff brush, can wear the gum back over many years.
• Tooth position and tooth movement. Roots that sit outside the bony housing, including after orthodontic movement, have thinner cover and recede more easily.
• Frenum pull. A tight band of tissue attaching the lip or cheek close to the gum edge can tug on it.
• Smoking and diabetes. Both are risk factors for gum disease, and smoking is linked to less root coverage after grafting; tell the dentist about either.

Finding the cause matters because the habits or conditions that produced the recession can keep acting after a graft. Changing a brushing habit costs nothing and is often part of the plan whether or not surgery follows.

Monitoring or grafting: how the conversation usually goes

With the measurements in hand, the dentist can tell you whether the recession is shallow and stable or deep, thin-walled and progressing. Shallow recession around a healthy, comfortable root with a good band of gum below it can often be monitored: the measurements are repeated at check-ups, brushing is adjusted, and a graft is considered only if the numbers change. Grafting is more likely to be suggested when the root is sensitive or decaying, when the gum is thin and the recession is advancing, or when the look of a long tooth bothers you. If tooth movement with aligners or braces is planned, ask whether the gum should be assessed first. The companion guide on whether receding gums always need a graft walks through that decision in more detail.

Whatever is recommended, ask for the findings, the recommendation and the alternatives in writing before you decide. A useful written plan names the teeth involved, the recession depth at each, the suspected cause, what monitoring would involve, and if grafting is advised, the technique, the donor source and the follow-up visits.

If grafting is advised

Technique options

Most root-coverage surgery combines a piece of connective tissue placed over the exposed root with a way of moving the existing gum up to cover it. The connective tissue graft with a coronally advanced flap, in which the gum is lifted, moved toward the crown of the tooth and stitched over the graft, is widely regarded as the reference technique, and reviews of the research show a wide range of coverage results between studies rather than one predictable number. The tunnel technique avoids the surface incisions of a flap: a pocket is created under the gum and the graft is slid into it, an approach some clinicians prefer for several adjacent teeth. Randomized trials comparing the two approaches, each with a connective tissue graft, have found similar root coverage; in one multicenter trial of multiple recessions the tunnel method was associated with more gain in firm gum tissue and a milder surgical experience reported by patients, while across trials the flap approach may give more coverage for a single tooth. Which is suitable for you depends on the number of teeth, the thickness of your gum and the position of the papillae, which is why the measurements come first.

The practice's gum grafting page mentions the tunnel technique. Ask at the consultation which techniques are offered for your situation and whether the surgery would be done at the office or by referral to a periodontist (a dentist who specializes in gum treatment).

Donor sources

The graft tissue is most often taken from your own palate, which is the basis of the reference technique and means a second surgical site in the roof of the mouth. Alternatives include processed donor tissue and collagen-based materials that avoid the palate; these can be an option in selected cases, and the written plan should say which is proposed and why.

Healing and what to arrange

When the palate is the donor site, discomfort there is usually greatest in the first few days and then settles, and dressings or a protective plate over the palate can reduce it. Some bleeding, altered sensation in the palate and changes to how you eat are reported, and are usually mild and short-lived. Practical steps to arrange ahead of time:

• Time. Plan a quiet day or two with no strenuous activity, and avoid scheduling important speaking engagements in the first week.
• Food. Stock soft, cool foods. Chewing on the grafted side and hot or crunchy foods are generally avoided until you are told otherwise.
• Cleaning. You may be asked not to brush the grafted area for a period and to use a rinse instead, while brushing the rest of the mouth normally.
• Smoking. On average, smokers achieve less root coverage than nonsmokers after these procedures. If you smoke, raise it at the consultation; stopping before and after surgery is part of giving the graft its best chance.
• Pain relief and comfort. Use what is prescribed or recommended, as directed on the label. The practice lists nitrous oxide, prescription anti-anxiety medication and longer appointments among its comfort options; ask whether they apply to grafting.
• Follow-up. Ask how many review visits are planned and when stitches are removed or dissolve.

Mild swelling and a little oozing are common in the first days. Bleeding that does not stop with firm pressure, rapidly spreading swelling of the face or neck, fever with swelling, or any difficulty breathing or swallowing are reasons to call 911 or go to the nearest emergency department rather than wait for an appointment; the guide on facial swelling with tooth pain explains these warning signs.
