Can a Periodontist Regrow Gums? Treatment Options for Receding Gums

If you've noticed your teeth looking longer, or you feel a sensitive notch where your tooth meets the gumline, you're probably dealing with gum recession. And the first question almost every patient asks me is the same: "Can gums grow back?"

The honest answer is layered. Gums do not spontaneously regenerate the way skin closes a paper cut. But that does not mean nothing can be done. In the right hands, gum tissue can be surgically rebuilt, repositioned, and in some cases even regenerated alongside the underlying bone. As a Yale-trained periodontist and UCLA clinical faculty member who performs gum grafting and regenerative procedures every week, I want to walk you through what's realistic, what works, what doesn't, and how to decide which treatment is right for your situation.

What Gum Recession Actually Is

Gum recession is the loss of gum tissue along the side of a tooth, which exposes more of the tooth — and sometimes the root surface — than should normally be visible. It is one of the most common reasons adults end up in my chair.

Three things are happening when gums recede. First, the soft tissue moves apically (toward the root tip). Second, the underlying bone usually shrinks alongside it. Third, the root surface, which is not protected by enamel, becomes exposed to the mouth — leading to sensitivity, higher decay risk, and an aesthetic concern many patients describe as "looking long in the tooth."

Recession is graded clinically using systems like the Miller or Cairo classifications, which describe how far the tissue has receded and how much surrounding bone has been lost. This classification matters because it tells us how predictable root coverage will be after treatment.

Why Gums Recede in the First Place

You can't pick the right treatment without understanding the cause. If we surgically rebuild your gumline but don't address what caused the recession, you'll be back in my chair within a few years. The most common causes I see are:

• Periodontal (gum) disease. Chronic inflammation from bacterial plaque destroys the bone and connective tissue that hold gum tissue in place. This is the most common cause in adults and the one that absolutely must be controlled before any grafting can succeed. Our periodontal treatment page covers how we diagnose and manage this.
• Aggressive toothbrushing. Using a hard-bristled brush, scrubbing horizontally, or brushing with excessive force physically wears the gum tissue away. This kind of recession often shows up first on the upper canines and premolars on the side of the dominant hand.
• Bite forces and grinding. Heavy clenching, bruxism, and certain occlusal interferences place repeated stress on individual teeth. Over years, this can cause bone and gum loss in a pattern called abfraction lesions.
• Thin gum tissue (thin biotype). Some patients are simply born with thinner gum tissue, which is more vulnerable to recession even without obvious trauma or disease.
• Orthodontic movement. Pushing teeth outside the bony envelope during orthodontics can cause recession years later. This is why pre-orthodontic periodontal evaluation matters.
• Other factors. Lip and tongue piercings, tobacco use, and high frenum attachments can all mechanically or biologically pull tissue away from the teeth.

So, Can Gums Actually Grow Back?

Let me give you the clearest possible answer.

On their own? No. Once gum tissue and the underlying bone have receded, the body does not rebuild them spontaneously. No mouthwash, no oil pull, no special toothpaste, no vitamin, no essential oil, no "natural remedy" sold online has ever been shown in a peer-reviewed clinical study to regrow lost gum tissue. If a product claims it can, be skeptical.

With professional treatment? Often, yes — but the word "regrow" is misleading. What a periodontist actually does is one of three things, depending on the case: (1) physically rebuild the gumline by transplanting new tissue, (2) reposition the existing tissue back over the exposed root, or (3) regenerate the lost periodontal attachment — meaning bone, ligament, and tissue — using biologic agents. Each of these is a different procedure with different indications.

So when someone asks me "can a periodontist regrow gums," what they really mean is: can the lost tissue be restored? And the answer is yes, in the vast majority of cases, provided the cause is addressed and the right technique is chosen.

Treatments That Actually Work

1. Connective Tissue Graft (CTG) — The Gold Standard

The connective tissue graft is the most predictable and best-studied treatment for restoring lost gum tissue. A thin layer of subepithelial connective tissue is harvested from the roof of your mouth (the palate), then carefully placed beneath the existing gum tissue at the recession site. The covering gum is repositioned over the graft, where it acts as a biologic scaffold and develops its own blood supply within days.

The result is thicker, more durable, attached gum tissue that looks and behaves like the rest of your gumline. Long-term studies show CTGs maintain root coverage for decades when properly executed and maintained. This is the procedure I most often recommend for single-tooth recession, recession near visible front teeth where esthetics matter, and any case where increasing the thickness of the tissue is critical for long-term stability.

You can read more about the specific procedure on our gum grafting page.

2. Pinhole Surgical Technique (PST)

Pinhole is a less invasive alternative for the right candidates. Instead of cutting and suturing, I make a tiny pinhole-sized entry above the recession, gently loosen the existing gum tissue, and reposition it down to cover the exposed root. Collagen strips inserted through the pinhole stabilize the tissue in its new position. No scalpels, no sutures, less swelling, no palatal harvest site, and the ability to treat multiple adjacent teeth in one visit. But Pinhole is not a universal substitute for grafting — it works best when there is enough existing tissue to reposition. In thinner cases, a graft is still the better long-term choice.

3. Free Gingival Graft (FGG)

A free gingival graft uses a slightly different tissue type from the palate and is placed directly on the recipient site rather than under existing tissue. It is most useful when the goal is to increase the band of attached, keratinized tissue rather than to cover an exposed root surface. We use FGGs for patients with very thin tissue at risk of progressive recession, particularly around dental implants or teeth that will receive future crowns.

4. Allograft and Xenograft Materials

For patients who prefer to avoid a palatal harvest, we can use donor tissue products such as acellular dermal matrix (e.g., AlloDerm) or porcine collagen matrices. These work well in selected cases and avoid a second surgical site. In my hands, autogenous (your own) tissue is still the most predictable, but allografts have a legitimate role when palatal anatomy is unfavorable or when treating multiple sites at once.

5. Guided Tissue Regeneration (GTR) and Biologics

When recession is accompanied by significant bone loss — as it often is in periodontitis cases — simple soft-tissue grafting may not be enough. Guided tissue regeneration uses barrier membranes, bone graft materials, and biologic agents like enamel matrix derivative or platelet-rich fibrin (PRF) to encourage true regeneration of bone, periodontal ligament, and gum tissue together. This is one of the most rewarding procedures I do — actually restoring the periodontal attachment, not just cosmetic coverage.

6. LANAP Laser Therapy for Disease-Driven Recession

When gum disease is the underlying cause of recession, treating the infection is the first priority. LANAP (Laser-Assisted New Attachment Procedure) uses a specific FDA-cleared laser protocol to remove diseased tissue, kill bacteria, and stimulate regeneration around affected teeth — without cutting or stitching. In appropriate cases, LANAP can stop the inflammatory process driving recession and, importantly, the FDA has cleared it for "true periodontal regeneration." It is not a replacement for grafting in cases of established recession, but it is often the first step before or instead of more aggressive surgery.

What "Natural" Remedies Won't Do

The internet is full of advice that ranges from useless to actively harmful. Oil pulling may reduce some surface bacteria but does not rebuild lost tissue. Vitamin C, green tea, and aloe vera support general healing but cannot reconstitute lost connective tissue or bone. Toothpastes marketed to "regrow gums" may reduce sensitivity by occluding exposed dentin tubules, but they do not regenerate tissue. Stem cell mouthwashes and peptide rinses currently on the market are not supported by clinical evidence for gum regrowth.

I'm not against complementary care — a healthy diet, smoking cessation, and good home hygiene make every periodontal treatment work better. But if a product promises gum regrowth without surgery, it is overpromising.

What a Realistic Treatment Plan Looks Like

When a new patient comes in concerned about receding gums, the process I follow in our Costa Mesa office is straightforward. First, a comprehensive evaluation: periodontal charting on every tooth, recession measurements in millimeters, and digital imaging to assess bone levels. Second, cause identification — disease, trauma, anatomy, or some combination. Third, a stabilization phase to control any active periodontal disease before grafting (often with scaling and root planing or LANAP). Fourth, the surgical phase, selecting the right procedure for your specific anatomy. Finally, maintenance — usually a three- or four-month cleaning interval for periodontal patients. Skipping any of these steps tends to predict long-term failure.

Recovery After Gum Grafting

Patients are often more anxious about recovery than the surgery itself. For a typical connective tissue graft, expect mild to moderate discomfort in the first 24-48 hours, controlled with over-the-counter pain relievers in most cases. The first week means soft, cool foods, no brushing at the surgical site, and a chlorhexidine rinse instead — most patients return to work within one to three days. Sutures dissolve or come out around week two, and gentle brushing resumes shortly after. Full tissue maturation, including final color match, takes three to six months. Most patients describe the experience as more inconvenient than painful.

Cost and Insurance

A single-tooth connective tissue graft typically ranges from $1,200 to $2,500 depending on complexity, with multi-tooth and Pinhole cases priced accordingly. Many dental insurance plans cover gum grafting when it is medically necessary — for example, when recession exposes root surface, causes sensitivity, or threatens tooth stability. Purely cosmetic cases may not be covered. We submit a pre-authorization to your insurance before scheduling treatment so you have a clear picture of what's covered, and we offer financing options for any remaining balance.

How to Stop Recession Right Now

Whether or not you ultimately need grafting, there are things you can start doing today to slow further recession. Switch to a soft-bristled toothbrush — or better, an electric brush with a pressure sensor — and use a gentle, vibratory motion at a 45-degree angle to the gumline rather than horizontal sawing. If you grind at night, a custom night guard distributes the forces that drive abfraction lesions. And if you have signs of gum disease — bleeding, bad breath, or pockets deeper than 3 mm — get a periodontal evaluation rather than just another routine cleaning. Recession is progressive; the earlier we intervene, the more conservative the treatment.

The Bottom Line

Can a periodontist regrow gums? In the way most people mean it, yes — the lost tissue can be restored, exposed roots can be covered, and the underlying periodontal attachment can often be regenerated. But it requires diagnosing the cause, controlling any active disease, and selecting the right procedure for your case. If you've noticed your teeth looking longer than they used to, get evaluated sooner rather than later. The conservative options are almost always better than waiting for the more aggressive ones.
