Board-certified periodontist Dr. Chanook David Ahn diagnoses the cause of your receding gums and recommends the most conservative, effective treatment -- from monitoring to microsurgical grafting
Gum recession occurs when the gum tissue that surrounds your teeth pulls back or wears away, exposing more of the tooth -- or the tooth's root surface -- than is normal. When the gum margin recedes, bacteria can accumulate in the gap that forms, and the root surface, which lacks the protective enamel covering the tooth crown, becomes exposed to decay, sensitivity, and structural damage.
Many patients first notice gum recession because their teeth appear longer than they used to, or because they experience a sharp sensitivity to hot, cold, or sweet foods. Some notice a visible notch where the gum meets the tooth, or feel a roughness at the gum line with their tongue.
What makes recession particularly concerning is that it is progressive. The gum tissue will not grow back on its own, and without identifying and addressing the underlying cause, it will continue. Early-stage recession may not cause symptoms, which is why many patients are unaware they have it until treatment becomes more complex. The cause determines the treatment -- which is why evaluation by a periodontist is essential before any treatment decision is made.
Gum recession is rarely caused by a single factor. In most cases, it results from a combination of causes acting on the tissue over time. Identifying the specific cause is essential because the treatment approach differs for each one.
Chronic periodontal disease is the most common cause of gum recession. When bacterial plaque and tartar accumulate below the gum line, the resulting infection destroys gum tissue and supporting bone. As the bone recedes, the overlying gum tissue follows. This type of recession is often generalized, affecting multiple teeth, and worsens if the underlying infection is not treated.
Brushing too hard or using a stiff-bristled toothbrush can physically wear away gum tissue over months and years. This recession, called toothbrush abrasion, often appears on the dominant-hand side and frequently affects premolars and canines. It is typically localized and may occur in patients with excellent oral hygiene and no periodontal disease.
Some people are born with naturally thin, delicate gum tissue that provides less of a protective cushion around the teeth. This thin phenotype is more susceptible to recession from normal brushing forces and everyday function. If you have thin, translucent tissue that reveals the outline of tooth roots, you may be genetically predisposed to recession regardless of hygiene habits.
Chronic grinding or clenching transmits excessive forces to the bone and gum tissue, causing them to remodel and recede over time. Bruxism-related recession tends to appear on teeth that bear the heaviest bite forces. Many patients grind at night without knowing it, and recession is often the first clinical sign.
Teeth moved orthodontically can develop recession during or after treatment, especially when moved outside the bony housing of the jaw. The risk is higher in patients with thin tissue biotype who undergo aggressive tooth movement without prior assessment of gum tissue and bone thickness.
Smoking and smokeless tobacco restrict blood flow to the gum tissue, impair immune response, and accelerate periodontal attachment breakdown. Smokeless tobacco placed directly against the gums causes chemical irritation and localized recession at the contact site.
Teeth that are crowded, rotated, or positioned outside the arch have thinner bone and gum tissue on the outer surface. A misaligned bite also distributes chewing forces unevenly, overloading certain teeth and contributing to localized bone loss and recession.
Oral piercings -- particularly tongue barbells and lip studs -- cause mechanical trauma through repetitive contact with the gums during speaking, eating, and unconscious fidgeting. This localized recession can be quite severe, especially with tongue piercings that contact the lower front teeth.
Gum recession often develops gradually, and many patients do not realize they have it until a dentist or hygienist points it out. However, there are several signs you can watch for between dental visits.
If you recognize any of these signs, a periodontal evaluation can determine the extent of your recession and whether treatment is needed now or whether monitoring is appropriate.
Your general dentist may be the first to identify gum recession during a routine exam. However, the evaluation and treatment of recession is a core specialty of periodontology, and there are important differences in how a general dentist and a periodontist approach the problem.
A general dentist may monitor mild recession and recommend a softer toothbrush. In some cases, a general dentist may recommend treatment when monitoring would suffice, or suggest a technique that is not the best fit for your specific recession. This is not a shortcoming of general dentistry -- it reflects that gum tissue surgery is a specialized field with nuances that require dedicated training.
Dr. Chanook David Ahn is a board-certified periodontist who completed his residency at Yale University, where he served as Chief Resident. Board certification by the American Board of Periodontology means Dr. Ahn has passed rigorous examinations demonstrating advanced knowledge in periodontal diagnosis, treatment planning, and surgical technique. He also serves as UCLA faculty.
When Dr. Ahn evaluates your recession, the assessment goes beyond measuring millimeters of tissue loss. He examines tissue thickness (phenotype), which directly affects treatment selection. He measures clinical attachment level -- the true level of support around the tooth. He identifies the actual cause, because treating recession without addressing the cause leads to recurrence. And he recommends the most conservative effective treatment for your specific situation.

The right treatment depends on the cause, severity, location, and tissue characteristics. Options range from conservative monitoring to advanced microsurgical techniques.
Not all gum recession requires surgery. When recession is mild, the tissue is thick and stable, and there is no ongoing attachment loss, monitoring with regular periodontal maintenance may be the most appropriate approach. The key is confirming that the recession is truly stable and not progressing through accurate measurements over time.
For patients whose primary concern is root sensitivity rather than progressive tissue loss, desensitizing agents such as prescription-strength fluoride varnishes and oxalate-based desensitizers can provide relief. These address the symptom but do not restore gum tissue or prevent further recession.
When recession is caused by a tooth positioned outside the bone envelope, orthodontic treatment can move the tooth back into a more favorable position. This can stabilize the recession and may eliminate the need for grafting. Orthodontic correction is sometimes performed before grafting to create the best foundation for surgical repair.
The connective tissue graft is the gold standard for root coverage. A small piece of connective tissue is harvested from beneath the palate surface and transplanted to the recession site, where it is secured over the exposed root. The CTG provides excellent predictability for root coverage, thickens the tissue to prevent future recession, and produces natural-looking results. For a detailed comparison, see our guide: Connective Tissue Graft vs. Pinhole Technique.
AlloDerm is a processed human donor tissue matrix used as an alternative to harvesting from the patient's own palate. This eliminates the palatal donor site and is particularly useful for patients needing grafting on multiple teeth. While AlloDerm provides good results in many cases, it may not achieve the same root coverage as a CTG in all situations. Dr. Ahn discusses the trade-offs during your consultation.
The tunnel technique elevates the gum tissue through small access points without traditional incisions or flap reflection. The graft material is threaded through the tunnel and positioned over the exposed roots. Because there are no visible incisions on the outer surface, this technique preserves blood supply and results in less scarring and faster healing. Learn more about our advanced gum grafting protocols.
The pinhole technique repositions existing gum tissue over exposed roots through a small pinhole-sized access point, stabilized with collagen strips. It avoids both palatal tissue harvesting and traditional incisions. It is best suited for certain types of recession and may not be appropriate for cases requiring significant tissue thickening.
Platelet-rich fibrin is prepared from the patient's own blood and placed at the surgical site to accelerate healing, reduce discomfort, and improve tissue regeneration quality. PRF is not a standalone recession treatment but enhances outcomes when combined with surgical grafting.
Not all gum recession requires surgery. A board-certified periodontist evaluates tissue thickness, attachment level, and recession cause before recommending treatment. At The Loft Dental Studio, Dr. Ahn's approach is conservative -- surgery is recommended only when the recession threatens tooth structure or will worsen without intervention.
Your first visit for a gum recession evaluation is a comprehensive diagnostic appointment, not a quick visual check. Dr. Ahn's goal is to understand exactly what is happening with your gum tissue, why it is happening, and whether treatment is needed now or whether monitoring is the better path.
The appointment begins with a review of your dental and medical history, including orthodontic treatment, grinding habits, oral hygiene routine, and family history of gum problems. Dr. Ahn then performs a comprehensive periodontal examination with full-mouth probing to measure pocket depths and attachment levels at six sites around every tooth. These measurements create a precise map of your periodontal health and identify areas where recession is accompanied by deeper pocketing or attachment loss.
Tissue thickness assessment is critical. Dr. Ahn determines whether your tissue is thin or thick, because this phenotype variable has a significant impact on treatment selection, predicted outcomes, and the likelihood of future recession. Digital radiographs and CBCT 3D imaging are taken when needed to evaluate bone levels and anatomical factors that influence treatment planning.
After the examination, Dr. Ahn provides an honest, straightforward discussion. If the recession is mild and stable, he will tell you it can be monitored. If treatment is needed, he explains why, walks through the specific procedure he recommends and why it fits your situation, and discusses outcomes, recovery, and cost. You will not be pressured into unnecessary treatment.
Gum grafting and other recession treatments are performed under local anesthesia, and most patients tolerate the procedures well with local numbing alone. However, for patients who experience dental anxiety, have a strong gag reflex, or are undergoing more extensive grafting involving multiple sites, IV sedation is available at The Loft Dental Studio.
IV sedation places you in a deeply relaxed, semi-conscious state throughout the procedure. You remain breathing on your own and can respond to verbal cues, but you will have little to no memory of the treatment afterward. Sedation is administered and monitored by trained personnel with continuous vital sign monitoring throughout the procedure.
If anxiety about the procedure is a barrier to seeking the gum recession treatment you need, sedation can make the experience comfortable and stress-free. Learn more about IV sedation options at our practice.

Call (714) 549-7030No. Gum tissue does not regenerate on its own once it has receded. In mild cases the recession may stabilize, but the lost tissue will not return naturally. The only way to restore gum coverage over an exposed root is through a surgical grafting procedure. Early evaluation by a periodontist is important because catching recession before it progresses gives you more treatment options and better outcomes.
A periodontist evaluates several factors: the depth of recession, whether it is stable or progressing, the thickness of remaining tissue, the level of bone support, and whether you have symptoms like sensitivity or aesthetic concerns. Mild recession with thick, stable tissue may only need monitoring. Progressive recession, thin tissue biotype, or recession that threatens tooth integrity typically warrants treatment.
For most patients with moderate to advanced recession, the connective tissue graft remains the gold standard because it provides predictable root coverage and increases tissue thickness. Minimally invasive options like the tunnel technique and pinhole surgical technique are excellent alternatives for appropriate candidates. In some cases, orthodontic correction or monitoring alone is the right approach. Dr. Ahn evaluates each case individually.
Gum graft surgery is performed under local anesthesia, and patients typically feel no pain during the procedure. Post-operative discomfort is generally mild to moderate, with most patients managing comfortably with over-the-counter ibuprofen. Discomfort peaks on day two or three and resolves over the following week. IV sedation is available for patients with dental anxiety.
A single-tooth gum graft typically ranges from $800 to $2,500, while multi-site grafting costs more. Many PPO dental insurance plans cover a portion of periodontal surgery including gum grafting. Our team verifies your benefits before treatment and provides a written estimate. We also offer financing and accept FSA and HSA payments.
A general dentist can identify recession, monitor mild cases, and address contributing factors like brushing technique. However, surgical recession treatment falls within the specialty of periodontics. A board-certified periodontist like Dr. Ahn has completed three additional years of residency training focused on gum tissue, bone, and supporting structures, including microsurgical techniques not part of general dental training.
Most patients return to desk work within one to two days. The initial healing phase lasts approximately two weeks on a soft diet. The graft matures and integrates over three to six months, during which color and contour blend with surrounding gums. For a week-by-week breakdown, see our gum graft recovery timeline.
