Feeling Like Your Gums Steal the Show
If you've ever looked at a photo and felt like your gums show more than your teeth, you're not alone. A "gummy smile" is common, and it can make people hold back when they laugh or cover their mouth without thinking. The teeth may be perfectly healthy underneath — they're just hidden by a little too much gum tissue.
The good news is that this is a well-understood, treatable situation. Crown lengthening is a cosmetic periodontal procedure that gently reveals more of the natural tooth, bringing balance back to your smile. Dr. Thomas Nguyen, a board-certified periodontist, performs this treatment for patients across Montréal who want either a more confident smile or the healthy foundation needed for restorative dental work.
What Is Crown Lengthening?
Crown lengthening is a minor surgical procedure that reshapes gum tissue — and sometimes a small amount of underlying bone — to expose more of a tooth's crown. Think of it like uncovering a pearl that's been set a little too deep in its setting: the pearl was always there, it just needed room to be seen.
There are two main reasons this procedure is performed, and they serve very different goals:
- Cosmetic crown lengthening addresses a gummy smile. By carefully removing excess gum tissue, more of each tooth becomes visible, and the teeth look longer and more proportionate.
- Functional crown lengthening creates enough healthy tooth structure for a restoration. If a tooth is broken near the gumline or a cavity extends below the gums, your dentist needs more surface to work with before placing a crown or filling.
Both versions are done with precision, and modern periodontal care gives us options in how they're performed. Some cases suit a traditional scalpel technique, while others can be handled with dental lasers, which tend to be gentler on soft tissue and can improve comfort during healing. During your consultation, Dr. Nguyen will explain which approach fits your specific anatomy and goals.
Why Do People Choose Crown Lengthening?
The reasons patients pursue this treatment usually fall into three categories, and often a single case touches more than one.
For a more balanced smile. When teeth appear short and the gums dominate, crown lengthening can restore natural proportions. Many patients tell us they simply want to feel comfortable smiling in photos, at work, or at family gatherings — a universal wish in a city as social as Montréal.
To make restorative dentistry possible. A crown or bridge needs a solid margin of healthy tooth to hold onto. When there isn't enough exposed structure, a restoration can loosen, leak, or trap bacteria at the edges. Creating proper access first gives that new crown a much better chance of lasting.
To support better oral health. Excess or uneven gum tissue can create pockets that are hard to keep clean. Reshaping the gumline can make brushing and flossing easier in that area, which helps reduce the risk of decay and irritation over time. This is one reason periodontal specialists view the procedure as more than cosmetic.
What to Expect: Procedure, Recovery, and Timeline
Understanding each step tends to ease a lot of the anxiety patients feel before periodontal surgery, so here's what the process generally looks like.
The Consultation
Everything starts with an evaluation. Dr. Nguyen examines your gums, teeth, and bite, and typically reviews imaging to understand what's happening below the surface. This is also when you talk through your goals — whether that's a more even smile or preparing a tooth for a crown. Because every mouth is different, this planning stage matters as much as the surgery itself.
The Procedure Itself
Crown lengthening is performed under local anesthesia, so the area is fully numb. Dr. Nguyen carefully removes the excess gum tissue, and if the case calls for it, reshapes a small amount of bone to achieve the right proportions. Sutures may be placed to help the gums heal into their new position. Most patients are surprised by how manageable the appointment feels.
Recovery Process
Healing happens in stages. In the first few days, mild swelling and tenderness are normal, and most people return to their usual routine fairly quickly while avoiding strenuous activity for a short period. A soft diet for roughly the first week and gentle oral hygiene around the treated area help things settle.
| Phase | General Timeline | What to Expect |
|---|---|---|
| Initial recovery | 1–3 days | Swelling and tenderness peak, then ease |
| Early healing | 1–2 weeks | Discomfort resolves; soft foods recommended |
| Full gum maturation | 2–3 months | Gums stabilize into their final shape |
| Bone remodeling (if bone was reshaped) | Up to 6 months | Complete stabilization in more complex cases |
You'll notice a visible difference in your smile right away, even though the gums continue to mature underneath over the following weeks. For functional cases, your dentist will usually wait until the tissue is stable before placing the permanent crown — the American Academy of Periodontology🔗 notes healing timelines vary by location in the mouth.
Cost and Investment
Cost depends on how many teeth are involved and how complex the case is — a single tooth prepared for a crown is very different from reshaping several teeth for cosmetic balance. Rather than a one-size-fits-all figure, Dr. Nguyen provides a clear estimate after evaluating your specific situation. Many patients find it helpful to think of the procedure as a long-term investment in both comfort and confidence.

Frequently Asked Questions
Q: Is crown lengthening painful?
A: The procedure itself is done under local anesthesia, so you shouldn't feel pain while it's happening. Afterward, most patients experience mild discomfort and some swelling for a few days, which is usually well managed with recommended pain relief and a soft diet.
Q: How long does the procedure take?
A: A single-tooth functional case can often be completed fairly quickly, while cosmetic cases involving several teeth take longer. Dr. Nguyen will give you a time estimate at your consultation once he knows the scope of your treatment.
Q: Will my gums grow back to where they were?
A: When crown lengthening is done properly by a periodontist, the reshaped gumline is designed to be stable and long-lasting. The gums heal into their new position rather than returning to the original level.
Q: Is this the same as a gum graft?
A: No — they're essentially opposite procedures. Crown lengthening removes tissue to expose more tooth, while a graft adds tissue to cover roots that have receded. If receding gums are your concern, our post on gum grafting🔗 explains that treatment in detail.
Q: What's the difference between cosmetic and functional crown lengthening?
A: Cosmetic crown lengthening improves the appearance of a gummy smile, while functional crown lengthening exposes enough tooth structure for a dentist to place a crown or filling. The surgical technique overlaps, but the goal is what differs.
Q: How do I know if I'm a candidate for crown lengthening in Montréal?
A: The best way is a professional evaluation. If you feel your teeth look short, your gums show heavily when you smile, or your dentist has said a tooth needs more structure before restoration, you may be a good candidate. An exam with Dr. Nguyen will confirm what's right for you.
