Proper suture type, correctly positioned sutures, and non-tension closures are some of the key elements to performing successful tooth removals. Properly closed surgical sites allow for the best opportunity for healing and prevent delayed healing, wound dehiscence, and infection. There are a number of factors that influence healing post-tooth removal, including existing systemic disease or chronic corticosteroid administration, but the most common cause of surgical dehiscence is tension on the gingival flap, caused by insufficient elevation of the periosteum. Also, presence of infection, sharp bone edges, and retained root remnants will delay or prevent post-surgical healing. Loose teeth caused by disease other than periodontal disease, like cancer, especially in cats, is another likely cause of non-healing tooth removal sites.
