Soft tissue grafting is often necessary to combat gum recession. Periodontal disease, trauma, aging, over brushing, and poor tooth positioning are the leading causes of gum recession which can lead to tooth-root exposure in severe cases.
When the roots of the teeth become exposed, eating hot and cold foods can be uncomfortable, decay is more prevalent and the aesthetic appearance of the smile is altered. The main goal of soft tissue grafting is to either cover the exposed root or to thicken the existing gum tissue in order to halt further tissue loss.
The three different types of common soft tissue grafts include:
Soft Tissue Grafting – A dermal matrix, tissue from a tissue bank, is sutured in by the grafting site. This type of graft is most commonly used for thickening existing tissue. This is the most common way to treat recession. It totally eliminates the surgical site in the roof of the mouth.
Connective tissue graft – Subepithelial tissue is another way we remedy the problem. This subepithelial connective tissue is removed from a small flap in the roof of the mouth and sutured to the grafting site.
Reasons for soft tissue grafting
Soft tissue grafting is an extremely versatile procedure that has many uses. Recent developments in dental technology have made soft tissue grafting more predictable and less intrusive. Here are some of the main benefits associated with soft tissue grafting treatment:
Increased comfort – Root exposure can cause substantial pain and discomfort. Eating hot, cold or even warm foods can cause severe discomfort. Soft tissue grafts cover the exposed root, decreases sensitivity and restore good health to the gum area.
Improved aesthetics – Gum recession due to periodontal disease can cause the smile to look “toothy” or the teeth to appear uneven in size. Soft tissue grafting can be used as a cosmetic procedure to re-augment the gums, and make the smile appear more symmetrical.
Improved gum health – Periodontal disease is a progressive condition that can destroy soft tissue very rapidly. When used in combination with deep cleaning procedures, soft tissue grafting can halt tissue and bone loss, and protect exposed roots from further complications.
What does soft tissue grafting treatment involve?
Initially, deep cleaning will be performed both above and below the gum line to clear the teeth and roots of calculus (tartar). The grafting procedure itself will generally be performed under local anesthetic, but this will depend on the size of the areas receiving grafts. A small incision will be made at the recipient site in order to create a small pocket. A split thickness incision is made in this pocket and the donor tissue is placed between the two sections of this area. The donor tissue strip is generally larger than the incision, so some excess will be apparent.
Platelet rich growth factors which stimulate natural tissue growth and promote good healing may be applied to the site before suturing. In addition, tissue-stimulating proteins may be added to encourage quicker tissue growth. Finally, the wound site will be sutured to prevent shifting, and surgical material will be placed to protect the sensitive area. Gum uniformity and substantial healing will take place in the first six weeks after the procedure.
