Patients often come to me with one question: "My smile shows a lot of gum — do I need veneers or implants?" The answer in many cases is neither. The most appropriate treatment, both clinically and aesthetically, may be crown lengthening — a procedure I perform weekly at AQUA Dent that's among the most impactful interventions for gummy smiles.
This guide explains: what crown lengthening is, when it's a medical necessity (not cosmetic), how it differs from veneers, the cost in Jeddah 2026, and the recovery period.

What is crown lengthening
Crown lengthening is a precise periodontal procedure in which we reshape the gum (and sometimes the underlying bone) to expose more of the tooth's natural crown. The result: longer-looking teeth, a more proportional smile, or access to a tooth structure needed for restoration.
The procedure is performed by a periodontics consultant under local anesthesia in 60–90 minutes per arch.
Two types: medical vs. cosmetic
1. Therapeutic crown lengthening (medical)
When a tooth has decay or fracture below the gum line and there's not enough tooth structure to hold a crown or filling. Without crown lengthening, the alternative is extraction. Cost: 3,500–6,000 SAR per tooth. Often partially covered by insurance.
2. Cosmetic crown lengthening
For "gummy smile" — when the smile shows too much gum (more than 3–4 mm of gum visible). The result: longer-looking teeth, a more balanced smile. Cost: 5,500–9,500 SAR per arch (full upper or lower arch). Not covered by insurance.
When is it the right choice
Therapeutic indications:
- Decay extending below the gum line.
- Tooth fracture below the gum line.
- Insufficient tooth structure to hold a crown or filling.
- "Biological width" violation by an old crown causing chronic inflammation.
Cosmetic indications:
- Gummy smile: showing more than 3–4 mm of gum when smiling.
- Asymmetric gum line between the front teeth.
- "Short-tooth" appearance due to gum overgrowth.
- Smile design without veneers when the underlying problem is gum-related, not tooth-related.
Crown lengthening vs. veneers
Most patients with a "gummy smile" go to clinics asking for veneers. The honest answer: veneers don't fix the underlying problem. The right comparison:
| Aspect | Crown lengthening | Veneers |
|---|---|---|
| Treats the underlying problem | Yes | No (only masks) |
| Reversibility | Mostly irreversible (gums don't grow back) | Permanent (enamel doesn't grow back) |
| Cost (8 teeth) | 5,500–9,500 SAR (one arch) | 12,000–25,000 SAR |
| Recovery period | 2–6 months for full healing | 2–3 weeks |
| Long-term effect | Lifetime | 10–15 years (replacement) |
| Need to maintain natural teeth | No tooth shaving | Requires shaving 0.3–0.7 mm |
For most "gummy smile" cases, crown lengthening is the right answer — alone, or sometimes combined with a few veneers for the full result.
Step-by-step process
- First consultation (45 min): Comprehensive exam, smile photographs, X-rays, gum measurements with a periodontal probe.
- Digital design (DSD): Designing the new gum line digitally — you see "before/after" before any incision.
- Mock-up (composite simulation): An optional simulation on the existing teeth to see the proportion before the procedure.
- Surgery (60–90 min per arch): Local anesthesia + carefully reshaping the gum (and sometimes bone) to the new line.
- Sutures: Fine sutures held for 7–10 days.
- Initial healing (2 weeks): The gum heals on the surface.
- Full healing (2–6 months): The bone and gum reach final stability.
- Final restoration (if needed): Veneers or crowns if a few teeth need them after lengthening.
Recovery period and aftercare
- First 24 hours: Mild swelling and minimal bleeding. Cold compress on the face.
- First 3 days: Soft cool foods, avoid hot drinks.
- First week: Painkillers (Ibuprofen) every 6 hours, chlorhexidine 0.12% mouthwash 2x daily.
- 7–10 days: Suture removal at the clinic.
- 2 weeks: Return to brushing the area normally with a soft brush.
- 2–6 months: Full final healing. The result you see in the first weeks differs slightly from the final result.
- Lifetime: Cleaning every 6 months at the clinic to maintain gum health.

FAQ
Q: Is the procedure painful?
A: Done under full local anesthesia — no pain during the procedure. After the procedure, mild discomfort for 3–5 days that's managed with simple painkillers.
Q: Will the result look natural?
A: Yes, when done by a periodontics consultant with the right design. The gum heals to the new line and looks completely natural.
Q: Will the gum grow back?
A: No. Once the gum and bone reshape into the new line, they stay there permanently (with normal care).
Q: How does this compare to laser-only treatment?
A: Laser is suitable for mild cases (gum overgrowth without bone repositioning). For most "gummy smile" cases, surgical crown lengthening (with bone repositioning) is needed for a stable long-term result.
Q: Can I have it done with veneers in the same session?
A: Crown lengthening must be done first, then 2–6 months for healing, then veneers (if needed). Doing them in the same session leads to inconsistent results.
Q: Are there alternatives to crown lengthening for a gummy smile?
A: For mild cases (3–4 mm exposed gum): Botox in the upper-lip muscles (temporary, repeat every 4–6 months). For moderate-to-severe cases: crown lengthening is the long-term solution.
Q: How long does the result last?
A: Lifetime, with normal gum care.
