Once the area is numb, the doctor will take a closer look to make sure there’s no dirt, debris, or other foreign objects inside the cut before sewing it together. An X-ray may also be ordered to help look for remaining debris. If you cut yourself on a piece of glass or sharp metal, for instance, it's important to make sure there are no remaining shards inside the cut.
The doctor may remove any dead tissues to help the healing process. He or she will then pull the edges of the cut together and, for each stitch, loop thread through either side of the cut and tie a knot to hold the wound closed.
