Covering exposed roots and rebuilding a gumline that has receded — including options with no scalpel and no sutures.
Gumline Restoration
Gum recession is the gradual retreat of gum tissue away from the tooth, exposing root surface that was never designed to be exposed. It creeps up slowly enough that most people notice the consequences — sensitivity to cold, teeth that suddenly look long — before they notice the recession itself.
Left alone it does not reverse. Exposed root has no enamel, so it is more vulnerable to decay and wears faster, and continued recession eventually threatens the bone support underneath.
Soft tissue grafting restores the missing tissue. Dr. Liu offers both traditional grafting and the Pinhole Surgical Technique — a scalpel-free, suture-free method that treats multiple teeth in a single visit with markedly faster recovery. He has published on connective tissue graft incision design in the International Journal of Periodontics & Restorative Dentistry.
- Covers exposed roots and reduces cold sensitivity
- Protects roots from decay and continued wear
- Restores a natural, even gumline
- Pinhole option requires no scalpel, sutures or palate donor site
- Multiple teeth treatable in a single appointment
- Halts recession before it costs bone support
What causes gum recession
Recession usually has more than one cause working together:
- Brushing too hard — the most common cause, and the most preventable. A hard-bristled brush used with force scrubs tissue away.
- Periodontal disease — infection destroys the gum and bone attachment directly
- Genetics — some people simply have thin gum tissue that is more prone to receding
- Bite forces — grinding and clenching stress teeth in ways that contribute to recession
- Tooth position — teeth sitting outside the arch have thin bone and thin gum over them
- Orthodontic movement — teeth moved beyond the bony envelope can recede
- Tobacco use — impairs the blood supply the gum depends on
Identifying the cause matters, because grafting a recession without addressing what caused it invites the same problem back. If aggressive brushing is the culprit, the technique has to change too.
Grafting options
Pinhole Surgical Technique
A small entry point is made in the gum and the existing tissue is gently loosened and repositioned down over the exposed root, held with collagen strips. No incisions, no sutures, and no tissue taken from the palate.
Because there is no donor site, the recovery that patients dread most simply does not happen. Several teeth — often an entire quadrant or more — can be treated in one appointment, and most people are presentable the next day.
Connective tissue graft
The long-standing gold standard. A thin layer of connective tissue is taken from beneath the surface of the palate and placed at the recession site. Root coverage is excellent and the aesthetic result blends naturally. This remains the right answer for many cases, particularly where tissue thickness must be increased.
Free gingival graft
Tissue is taken from the palate surface to thicken a band of gum that has become too thin to withstand normal function. Used when the goal is durable, attached tissue rather than root coverage.
Donor tissue grafts
Processed donor tissue can substitute for palatal tissue, avoiding a second surgical site altogether. Useful when several areas need treatment at once.
Grafting around implants
Implants need a healthy cuff of firm tissue around them just as natural teeth do. Grafting around an implant improves both long-term stability and appearance, particularly in the smile zone.
Frenectomy
The frenum is the small band of muscle tissue anchoring the lip to the jaw. In some people it attaches too close to the gum margin and pulls on it constantly, causing recession or forcing a gap between the front teeth.
A frenectomy releases that attachment, typically with a small graft placed to stop it reattaching in the same position. It is a short procedure, often combined with grafting or done ahead of orthodontic treatment.
What to Expect
The Gingival Graft Process
- EvaluationRecession is measured at each affected tooth and the underlying cause identified. Tissue thickness, root coverage potential and aesthetics all factor into which technique is appropriate.
- Technique selectionDr. Liu explains which grafting approach suits your case and why, including whether Pinhole is a realistic option for you — it is excellent, but it is not right for every pattern of recession.
- The procedurePerformed under local anesthesia. Pinhole cases typically take one to two hours for multiple teeth; traditional grafts vary with the number of sites.
- Early recoveryPinhole patients generally return to normal activity within a day or two. Traditional grafts involve more discomfort at the palate donor site for roughly a week. Soft foods and avoiding brushing the treated area are advised initially.
- Follow-upHealing is reviewed at scheduled visits. Once settled, you are shown exactly how to brush the area so the recession does not simply return.
Sensitive teeth at the gumline? Sensitivity to cold air or cold drinks at the gumline is often the first sign of exposed root surface. It is worth having looked at early — small recessions are considerably easier to treat than large ones.
Common Questions
Gum Grafting & Soft Tissue Grafts FAQs
It is less invasive, not universally better. Pinhole avoids incisions, sutures and a palate donor site, so recovery is much faster and more comfortable, and it treats several teeth at once.
That said, traditional connective tissue grafting is still the better choice in some cases — particularly where gum tissue is very thin and needs genuine thickening rather than repositioning. Dr. Liu is trained in both and will recommend based on your tissue, not on which technique sounds more appealing.
The procedure is done under local anesthesia and is not painful at the time. Recovery differs by technique: Pinhole patients typically report mild soreness for a day or two, while traditional grafts involve a tender palate donor site for about a week.
Post-operative discomfort is generally well managed with over-the-counter pain relief, and you will be given specific instructions and a direct line to the practice.
No. Gum tissue that has receded does not regenerate. Improving your brushing technique is essential to stop further loss, but it will not restore what has already gone — that requires grafting.
This is precisely why early treatment is worthwhile. Recession only moves in one direction if left untreated.
Grafts are intended to be permanent, and results are typically stable long term provided the original cause has been addressed. If aggressive brushing caused the recession and the brushing does not change, recession can recur at the same or neighboring sites.
Regular periodontal maintenance visits let us catch any early movement long before it becomes another graft.
