What suture is used to close tooth extraction sites?

• A. 3-0 to 5-0, monocryl
• B. 4-0, silk
• C. 6-0, nylon
• D. 2-0, gut

Answer: (A)

Closing extraction sites benefits from a suture that holds tissue gently yet doesn't require removal later. A resorbable, monofilament suture like monocryl is ideal because it provides secure mucosal closure during the critical early healing period and then gradually absorbs, leaving no foreign material to retrieve. Its single-filament design minimizes tissue drag and bacterial buildup, reducing inflammation in the delicate oral mucosa.

Other options are less suitable for socket closure: silk is braided and nonabsorbable, needing removal and tending to harbor bacteria; nylon is nonabsorbable and can irritate mucosa while requiring removal; gut (catgut) is absorbable but less predictable in resorption and can provoke a greater inflammatory response.
