Which method is referenced for closing the mouth of the deceased non-invasively?

The "dental-tie" method is a non-invasive technique used to close the mouth of the deceased. This method involves using ligatures, typically dental floss or a similar material, to secure the mandible (lower jaw) to the maxilla (upper jaw). By threading the material through the dental arches and tying a knot, the mouth is rendered closed without any need for incisions or invasive procedures. This is particularly advantageous because it minimizes physical alteration to the decedent and prevents any visible signs of intervention, which is important for both the respect of the deceased and the wishes of the family.

Other potential methods, such as the adhesive method, might involve the application of adhesives to keep the mouth closed, but this can be considered more invasive and might not provide the desired effect without potential complications. The suture method implies a form of stitching, which is certainly invasive and may lead to visible marks. The gauze method, while also non-invasive, may not offer the same level of effectiveness in securely keeping the mouth closed compared to the precision and control of the dental-tie method.
