You've seen the photos. The ones where you're laughing, genuinely happy, completely in the moment — and your first reaction when you see them is to zoom in on your gums. Too much of them. The teeth look short. The smile line looks uneven. The effect is a smile that doesn't reflect how confident you actually feel, and over time, the habit becomes automatic: close-lipped in photos, careful about wide laughs, quietly self-conscious in ways that feel harder to explain than, say, a chipped tooth or obvious discoloration.
A gummy smile — clinically referred to as excessive gingival display — is one of the most common cosmetic dental concerns that patients bring to Barrera Advanced Dentistry in Torrance, and one of the most treatable. The procedure that addresses it, gum contouring, is faster, less involved, and more dramatically effective than most patients expect. And with summer schedules, weddings, family photos, and events filling up the calendar, June is one of the most motivated times of year for patients to finally take action on something they've been thinking about for years.
What Makes a Smile Look "Gummy"
A smile is considered aesthetically gummy when more than approximately 2–3 millimeters of gum tissue is visible above the upper teeth when smiling naturally. Beyond that threshold, the gum line begins to visually dominate the smile, and the teeth — even if they're in excellent condition — appear shorter, less proportional, and less prominent than they should be.
The causes vary:
- Altered passive eruption: This is the most common cause of a gummy smile. In normal dental development, gum tissue recedes as teeth fully erupt, revealing the full crown length. In altered passive eruption, the gums don't fully recede — they remain covering part of the crown, making teeth appear shorter than their actual length even though the underlying tooth structure is entirely normal.
- Hyperactive upper lip: Some patients have a lip that elevates further than average when smiling, revealing more gum tissue than would otherwise be visible. This is a muscular dynamic rather than an issue with the gum tissue itself.
- Vertical maxillary excess: In some cases, excess gum display is related to the vertical development of the upper jaw — a skeletal consideration that may require more comprehensive treatment.
- Small teeth relative to gum coverage: Teeth that appear small can be a matter of proportion — the gums are covering a normal-sized tooth, but the visible portion is disproportionately small.
For most patients presenting with a gummy smile, altered passive eruption is the primary driver, and gum contouring addresses it directly.
What Gum Contouring Actually Involves
Gum contouring — also called crown lengthening or gingival recontouring — is a procedure in which the dentist precisely removes and reshapes excess gum tissue to reveal more of the natural tooth crown, creating a more proportional and aesthetically balanced smile line.
At Barrera Advanced Dentistry, the procedure is performed under local anesthesia. The treatment area is completely numb before work begins. Dr. Adriana Barrera, who has more than 20 years of clinical experience serving patients throughout the South Bay and brings UCLA-trained cosmetic expertise to every procedure, carefully marks and reshapes the gum line to achieve the planned aesthetic result. The goal is not just to remove tissue, but to create a natural, symmetrical gum contour that complements the shape and proportion of each tooth individually.
Depending on the extent of the procedure, recovery is typically brief. Some tenderness and mild swelling in the first few days are normal. Most patients are comfortable returning to normal activities quickly. The final result continues to refine as the tissue heals over the following weeks, revealing the full impact of the change.
The Before-and-After Transformation
It's difficult to overstate how significantly gum contouring changes the visible quality of a smile, particularly for patients whose teeth are otherwise in good condition. Revealing even two or three additional millimeters of tooth structure transforms the apparent length of the teeth, the proportion of the smile, and the overall character of the face at rest and in motion.
For many patients, this single procedure accomplishes what they imagined would require veneers, whitening, and orthodontics combined — because the issue was never the teeth themselves. It was the framing. Once the gum tissue is properly contoured, the teeth that were always there are simply visible.
For patients who do want to pursue additional cosmetic treatments — veneers, bonding, whitening — gum contouring is often performed first, since it establishes the correct gum line before any restorative or cosmetic work is placed. Doing it in the right sequence means a result that's cohesive and long-lasting.
Why This Summer Makes Sense
Summer is an unusually good time to pursue gum contouring for a few practical reasons. If you have events — a wedding, a reunion, a milestone birthday — planning the procedure for early June gives the tissue time to heal fully before those occasions. Recovery is not extensive, but having a few weeks of healing time before a major photo opportunity is worth planning for.
The summer also tends to bring a natural reflection period for patients. More photos, more social occasions, more time thinking about how they want to present themselves. For patients who've been aware of their gummy smile for years but haven't acted on it, that moment of "this is the year" tends to arrive in June.
Barrera Advanced Dentistry also serves Spanish-speaking patients — a reflection of the diverse South Bay community the practice has cared for since 1995.
