Key Takeaway
Consider suture-less closure as an alternative to primary closure for mandibular third molar extraction, but note the lack of statistical significance.

This meta-analysis of 10 RCTs evaluated suture-less wound closure versus multiple-suture primary closure in patients undergoing surgical extraction of mandibular third molars. The primary outcomes were early postoperative pain, facial swelling, and trismus. Secondary outcomes included wound-healing and infection-related outcomes.

Pooled results showed lower pain at 48 hours (mean difference -0.46, 95% CI -3.69 to 2.77, p=0.33), lower facial swelling at 48 hours (mean difference -0.56, 95% CI -1.35 to 0.22, p=0.159), and lower trismus at 7 days (mean difference -0.38, 95% CI -1.78 to 1.22, p=0.09) in the suture-less group. However, none of these differences reached conventional statistical significance.

Limitations include high heterogeneity (I2 > 50%) across studies. Adverse events, serious adverse events, and discontinuations were not reported. The authors note that suture-less wound closure may be a safe and reasonable alternative to multiple-suture primary closure, as both are associated with comparable early postoperative outcomes. Clinicians should interpret these findings cautiously given the lack of statistical significance and heterogeneity.

Recovering from wisdom tooth surgery often involves significant discomfort, including facial swelling and difficulty opening your mouth. For patients undergoing surgical extraction of mandibular third molars, doctors are looking for ways to make this recovery period smoother.

A review of 10 clinical trials compared a suture-less wound closure method against the traditional use of multiple sutures. The results showed that patients who had the suture-less treatment reported lower levels of pain at 48 hours, less facial swelling at 48 hours, and less trismus (difficulty opening the mouth) after seven days.

While these findings suggest that suture-less closure is a safe and reasonable alternative to traditional stitches, it is important to note that the results did not reach conventional statistical significance. This means while the numbers trended in favor of fewer sutures, the evidence is still being weighed carefully due to high variation between the studies.

What this means for you:
Suture-less wound closure may offer a comfortable alternative to traditional stitches after wisdom tooth surgery.

Common questions

Does suture-less closure make recovery easier after wisdom tooth surgery?

The study found that patients who had suture-less wound closures reported lower levels of pain at 48 hours and less facial swelling at 48 hours compared to those with multiple sutures. They also experienced less trismus, which is the difficulty opening your mouth, at seven days. However, these results did not reach conventional statistical significance.

Is suture-less closure safe for wisdom tooth extractions?

The data suggests that suture-less wound closure is a safe and reasonable alternative to multiple-suture primary closure for mandibular third molar surgery. Both methods were associated with comparable early postoperative outcomes, making it a viable option for patients undergoing this procedure.

How does the study compare suture-less methods to traditional stitches?

The analysis of 10 trials compared both methods. While the suture-less group showed lower mean differences in pain, swelling, and trismus, the high variation between studies means the results are not yet definitive. You should discuss these options with your surgeon to see if it is right for you.

Surgical extraction of mandibular third molars is a common procedure performed in clinical practice yet it commonly yields postoperative pain, facial swelling, and trismus. While multiple-suture primary closure has traditionally been used, suture-less wound closure has emerged as an alternative. This systematic review and meta-analysis aimed to compare the effect of suture-less vs. multiple-suture wound closure on early postoperative pain, facial swelling, and trismus after mandibular third molar surgery. A comprehensive literature search was conducted in several databases for articles from January 2000 to December 2025. Only randomized controlled trials comparing suture-less and multiple-suture closure after surgical extraction of mandibular third molars were included. Meta-analyses were performed in RevMan 5.4 using a random-effects model due to substantial heterogeneity (I2 > 50%). Rob 2 tool was used for quality assessment of the included studies. Ten RCTs were included. Meta-analysis showed that pain at 48 h was lower in the suture-less group (mean difference: −0.46; 95% CI: −3.69, 2.77; p = 0.33), but the difference was not statistically significant. Similarly, facial swelling at 48 h was lower in the suture-less group (mean difference: −0.56; 95% CI: −1.35, 0.22; p = 0.159), and trismus at 7 days was lower (mean difference: −0.38; 95% CI: −1.78, 1.22; p = 0.09), though neither reached conventional significance. Narrative synthesis indicated that suture-less closure was associated with comparable wound-healing and infection-related outcomes compared with multiple-suture closure. Suture-less techniques may be considered a safe and reasonable alternative as both approaches were associated with comparable early postoperative outcomes to multiple-suture primary closure in terms of pain, facial swelling, and trismus. Suture-less wound closure after surgical extraction of mandibular third molars can be a valid choice particularly when the goal is to minimize early inflammatory sequelae and patient discomfort.
