- Typically, sutures would be ideally removed 8-12 days after placement.
- Resorbable sutures offer the advantage that they may not be removed.
- Suture removal is usually a quick and pain free procedures, and there is no need for anesthetic.
Sutures are available in a number of types and sizes (diameter) to ensure that wound margins are free of tension, allowing healing by primary intention. Dental sutures are classified into two types, absorbable and non-absorbable. They can also be classified as mono-filament or multi-filament, based on their construction, and whether they are made from natural or synthetic materials.
Suture removal depends on the material and procedure. Generally, the healing of the wound takes place after 8 to 12 days. At the start of the process, the patient might feels a firm tug on each stitch if they end up dragging knotted end through the healing tissue. Nevertheless, anesthetic is usually not needed.
Abandoning a suture submucosally can lead to foreign body reactions, infection and eventually implant loss.
Even resorbable sutures may benefit from removal of remnants after healing. The suture should be clearly identified, then pulled towards the wound with a hemostat or cotton forceps and taken out using a scissors or a blade. After removal of sutures it may be good to swab the mucosa clean from any debris with moist gauze.
In case of major surgical procedures or in patients suffering from bleeding disorders, it is preferably remove first one out of two sutures to verify that the wound closure holds. Otherwise the rest of suture removal is postponed.
After suture removal, the patient will continue the specific oral hygiene procedures pre-scribed after surgery for 2-3 days.
