Gummy Smile Correction: Botox vs. Lip Repositioning vs. Crown Lengthening
A gummy smile shows more gum than teeth when you smile—and if you have one, you're probably self-conscious about it. The good news? Three solid treatment options exist, each with pros and cons worth understanding.
What Causes a Gummy Smile?
Before choosing treatment, it helps to understand what's happening. A gummy smile typically stems from:
- Hyperactive upper lip: Your muscles pull your lip up too far
- Overgrown gum tissue: Excess gum naturally covers more tooth
- Short tooth crowns: Your teeth appear smaller because they're naturally short
- Jaw positioning: Your upper jaw sits lower, naturally showing more gum
Your dentist can determine the cause during an exam, which guides treatment selection.
Treatment Comparison Table
| Treatment | Procedure Type | Cost (2026) | Longevity | Recovery | Invasiveness | Best For |
|---|---|---|---|---|---|---|
| Botox | Injectable | $400–$800 | 3–4 months | None | Minimal | Hyperactive upper lip |
| Lip Repositioning | Surgery | $1,500–$3,000 | Permanent | 1–2 weeks | Moderate | Excessive muscle pull |
| Crown Lengthening | Surgical | $1,000–$3,000 | Permanent | 2–4 weeks | Moderate | Overgrown gum tissue |
| Combination Approach | Multiple | $2,500–$6,000+ | Varies | Staggered | Varies | Complex cases |
Option 1: Botox for Gummy Smile
How it works: Botox is injected into the upper lip muscles to relax them, preventing the lip from rising too high during a smile.
Pros: - Non-invasive, no surgery - Immediate results (visible in 3–5 days) - No downtime - Fully reversible - Affordable for trying a solution
Cons: - Results last only 3–4 months (requires maintenance) - Doesn't address overgrown gum or short teeth - Repeated injections add up over time - May feel slightly stiff if overdone
Cost: $400–$800 per treatment (recurring every 3–4 months)
Longevity: Temporary; results fade as the Botox wears off
Who it works for: People with a hyperactive upper lip muscle but normal gum levels and tooth length.
Option 2: Lip Repositioning Surgery
How it works: The surgeon reduces the movement of your upper lip by tightening the muscles underneath, preventing the lip from rising too far.
Pros: - Permanent results - Addresses the root cause (muscle pull) - Single procedure - Works even during big smiles and laughing - No ongoing maintenance
Cons: - Requires minor oral surgery - 1–2 weeks recovery (swelling, discomfort) - Slightly higher cost than Botox - Irreversible - May affect speech or eating if too aggressive
Cost: $1,500–$3,000
Longevity: Permanent
Who it works for: People with excessive upper lip pull who want a permanent fix without ongoing treatments.
Option 3: Crown Lengthening
How it works: The dentist or periodontist removes excess gum tissue (and sometimes bone) to expose more of the tooth surface, making teeth appear longer and less gum visible.
Pros: - Permanent results - Addresses actual gum overgrowth - Can improve teeth appearance significantly - Works for multiple teeth at once
Cons: - Surgical procedure (more invasive than Botox) - 2–4 weeks recovery with swelling - Risk of gum recession long-term - Can make teeth look longer, which some dislike - May require bonding or veneers if tooth color looks uneven
Cost: $1,000–$3,000 depending on number of teeth
Longevity: Permanent
Who it works for: People with genuinely overgrown gum tissue covering too much of the tooth.
Combination Approach
Some people benefit from combining treatments:
- Botox + crown lengthening: Relaxes the lip muscle and removes excess gum for comprehensive results
- Lip repositioning + tooth bonding: Fixes the smile height and improves tooth appearance simultaneously
- Crown lengthening + veneers: Exposes more tooth and improves tooth shape and color
Combination approaches cost $2,500–$6,000+ but address multiple underlying issues.
How to Choose
Pick Botox if: - You have a normal gum line but too much lip movement - You want to try something before surgery - You're budget-conscious - You want zero downtime
Pick Lip Repositioning if: - You want a permanent fix - Excessive upper lip pull is your main issue - You're willing to have minor surgery once - Long-term cost matters more than upfront expense
Pick Crown Lengthening if: - You genuinely have overgrown gum tissue - Your dentist confirms gum is the issue - You're ready for a surgical procedure - You want to improve tooth-to-gum proportion overall
Key Takeaway
Your gummy smile fix depends on what's actually causing it. A consultation with a cosmetic dentist or periodontist will pinpoint whether your issue is muscle, gum, or tooth-related—and guide you toward the best option.
Recovery Timeline by Treatment
Botox: 0 days downtime; minor swelling for 24 hours
Lip Repositioning: 1–2 weeks downtime; avoid strenuous activity, swelling peaks day 3–5
Crown Lengthening: 2–4 weeks downtime; avoid hard/crunchy foods, normal oral hygiene resumes after 2 weeks
Aftercare Matters
Whichever option you choose, follow your dentist's aftercare instructions carefully. Infection, poor healing, or premature activity can compromise results.
Final Thoughts
A gummy smile doesn't have to be permanent. Modern cosmetic dentistry offers safe, effective options for every situation and budget. The key is getting a proper diagnosis so you choose the treatment that actually addresses your specific issue—not just any gummy smile treatment.
