After oral surgery—whether tooth extraction, gum grafting, or implant placement—your surgeon closes the wound with sutures (stitches). Two main types exist: dissolvable (resorbable) stitches that disappear on their own, and traditional stitches that need removal. Understanding the difference helps you know what to expect during healing.
What Do Sutures Do?
Sutures hold tissue layers together while your body heals the wound. They approximate (bring close together) the edges so healing tissue can knit properly. Without sutures, wounds heal with larger scars and less precise closure.
Sutures are typically removed or dissolve within 1-2 weeks—after which the wound is strong enough that stitches are no longer needed.
Dissolvable (Resorbable) Sutures
Stitches made from materials that your body naturally breaks down and absorbs over time. No removal appointment needed.
Materials Used
Plain Gut (Natural): - Derived from animal intestine - Least expensive - Dissolves in 7-10 days - Least predictable dissolution rate - Rarely used now
Chromic Gut (Natural): - Chemically treated gut - Dissolves in 14-21 days - More predictable than plain gut - Occasionally used
Synthetic Absorbable: - Polydioxanone (PDS) - Polyglactin 910 (Vicryl) - Poliglecaprone (Monocryl) - Most common modern choice - Dissolve in 10-21 days depending on type - Predictable dissolution - Excellent tissue compatibility
How They Work
Your body's immune system gradually breaks down the suture material. The process starts immediately after placement: - Days 1-3: Minimal breakdown - Days 4-7: Noticeable reduction - Days 10-14: Often dissolved - Days 14-21: Completely absorbed
Timeline depends on suture type and your healing rate.
Advantages of Dissolvable Sutures
- No removal appointment: Saves you a second visit
- Less anxiety: No needle/instrument feeling
- Gradual removal: Tissue releases sutures as healing progresses
- Less discomfort: No tugging sensation during removal
- Time-efficient: Eliminates follow-up appointment
- Less foreign body reaction: Gradual removal minimizes irritation
Disadvantages of Dissolvable Sutures
- Less predictable: Some dissolve early, some remain longer
- Early dissolution: If they dissolve too quickly, wound edges can separate
- Patient doesn't control timing: Must wait for dissolution
- Slightly more expensive: Synthetic materials cost more
- Still need monitoring: You need to watch for signs of infection
- Can't be adjusted: If closure becomes loose, can't tighten
Best For
- Patients who can't return for suture removal
- Younger patients (better healing)
- Gum grafts (better to avoid suture removal trauma)
- Extensive surgery where multiple visits are burdensome
- Those with needle anxiety
Non-Dissolvable (Non-Resorbable) Sutures
Traditional stitches made from materials that don't break down. Must be manually removed in a follow-up appointment.
Materials Used
Silk: - Natural fiber - Excellent handling properties - Traditional choice - Braided (increases surface area, better grip) - Requires removal
Nylon: - Synthetic, very strong - Monofilament (smooth, less traumatic) - Excellent strength - Popular choice - Requires removal
Polyester: - Synthetic, very strong - Braided (easier to tie/handle) - Excellent for tension areas - Requires removal
Stainless Steel: - Strongest option - Used in high-tension areas - Rarely used in dental (mainly surgical) - Requires removal (or special cutting)
How They Work
Non-dissolvable sutures remain intact indefinitely. They don't break down; they must be physically removed. Removal is typically quick (5-10 minutes) and painless if done properly.
Advantages of Non-Dissolvable Sutures
- Predictable: Know exactly when removal happens
- Reliable retention: Won't dissolve prematurely
- Adjustability: Can be tightened if wound edges separate
- Can be accessed: Easy to remove if needed
- Traditional reliability: Used successfully for decades
- Less expensive: Slightly cheaper than absorbable
- No body breakdown needed: Don't rely on healing rate
Disadvantages of Non-Dissolvable Sutures
- Removal appointment required: Second visit necessary
- Discomfort during removal: Slight tugging/pressure sensation
- Removal anxiety: Some patients anxious about needle
- More office visits: Inconvenient for some
- Longer foreign material time: Silk/nylon in mouth longer
- Slight inflammation risk: Material irritates gums slightly
Best For
- Complex surgery requiring precise retention
- Areas under tension (need maximum strength)
- Situations where predictable removal is important
- Patients who can return for removal (usually 7-10 days)
- Traditional surgeon preference
Side-by-Side Comparison
| Feature | Dissolvable | Non-Dissolvable |
|---|---|---|
| Removal Needed | No | Yes (7-10 days) |
| Appointment Required | One | Two |
| Cost | Slightly higher | Slightly lower |
| Predictability | Moderate | High |
| Patient Convenience | Better | Lower |
| Removal Discomfort | None | Minimal |
| Time in Mouth | 10-21 days | 7-10 days |
| Early Dissolution Risk | Possible | No |
| Adjustment Possible | No | Yes |
| Patient Compliance | Needed for monitoring | Just needs to return |
| Infection Risk | Equal | Equal |
| Healing Quality | Equal | Equal |
Timeline Expectations
With dissolvable sutures: - Day 0: Placed during surgery - Days 1-3: Healing begins, sutures stable - Days 4-7: Noticeable loosening, possible fraying - Days 8-14: Dissolution continuing, gradual suture absence - Day 21: Completely dissolved (usually sooner)
With non-dissolvable sutures: - Day 0: Placed during surgery - Days 1-6: Healing, sutures in place - Day 7-10: Suture removal appointment - Post-removal: Quick healing complete
Dissolution Timeline Variations
Dissolvable suture dissolution depends on: - Suture type: Vicryl (10-14 days), PDS (14-21 days), Monocryl (7-14 days) - Individual healing rate: Faster healers break down sutures faster - Infection: Infection speeds dissolution - Suture location: Mouth (wetter) dissolves faster than dry areas - Suture size: Thicker sutures last longer
Your surgeon should tell you approximately when yours will dissolve.
What to Expect During Healing
With dissolvable sutures: - You'll see gradual fraying/loosening - Small bits may come out (normal) - Can be slightly uncomfortable as they loosen - Must avoid pulling at them - Don't assume dissolution means healing is complete - Still practice good oral hygiene
With non-dissolvable sutures: - They remain stable - Return 7-10 days for removal - Removal takes 5-10 minutes - Slight pressure sensation during removal - Painless if done properly - Healing continues for weeks after removal
Pain and Discomfort
Dissolvable: Minimal pain if dissolution is slow. If they dissolve quickly and wind opens, can be uncomfortable.
Non-dissolvable: Slight discomfort during removal (tugging feeling), but not painful. Local anesthetic before removal takes discomfort away.
Overall, dissolvable are more comfortable for sensitive patients (no removal procedure).
Complications and When to Call
Dissolvable issues: - Wound opening if sutures dissolve too early (call if happens) - Sutures remaining too long (call if still present at 3 weeks) - Signs of infection (increasing pain, swelling, pus)
Non-dissolvable issues: - Sutures too tight (tissue swelling around them—call) - Signs of infection (increasing pain, swelling, pus) - Forgetting removal appointment (call to reschedule immediately)
Surgeon Choice of Suture Type
Most surgeons have a preference based on: - Surgical type: Complex surgery often uses non-dissolvable - Location: Gum tissue often uses dissolvable - Predictability: Non-dissolvable more predictable - Patient factors: Can't return? Use dissolvable - Surgeon comfort: Experience with specific types
Ask your surgeon: 1. "What suture type are you using?" 2. "When will they dissolve/be removed?" 3. "What should I watch for during healing?" 4. "Can I remove them myself if needed?" (No—always professional)
Special Situations
Suture allergies: Rare, but possible. Tell your surgeon if you have known suture/material allergies.
Immunocompromised: May affect healing/dissolution rate. Tell your surgeon.
Difficult healing: Sometimes surgeons keep non-dissolvable longer than usual.
2026 Advances
Newer dissolvable sutures are more predictable. Some have "fast" and "slow" versions controlling dissolution timeline.
Antimicrobial sutures coated with compounds that reduce infection are emerging.
Overall trend is toward dissolvable for patient convenience when appropriate.
The Bottom Line
Dissolvable sutures: Better convenience (no removal), but requires trust in dissolution timing and monitoring for problems.
Non-dissolvable sutures: Predictable, traditional approach requiring return visit for removal.
Both result in equally good healing and outcomes. Choice depends on surgery type and your preference for convenience vs. predictability.
Your surgeon's recommendation should be based on your surgical situation. If they explain their choice clearly, you can trust their clinical judgment.
Key Takeaway: Dissolvable sutures eliminate a return visit but require trusting the dissolution timeline. Non-dissolvable sutures are predictable but require removal appointment. Both produce equally good surgical results.
