Gum recession is very common but in some instances it can effect the appearance of your smile, making teeth appear longer and also leading to an increase in sensitivity. Rarely but in the worst cases it could cause you to lose teeth. Common causes of gum recession are overbrushing, gum disease and lip/tongue piercings. It is possible to perform a gum graft to thicken the gum in order to prevent further shrinkage and in some cases it is even possible to regrow the gum back over the tooth.
During your appointment a local anaesthetic injection will be placed into the gum next to the teeth being treated. When the gum and teeth are completely numb, the gum is gently lifted to allow a graft to be placed underneath. Finally the gum is stretched and replaced with a few small stitches covering the previously exposed tooth root. The most common place to take a graft is from the roof of the mouth, which contains thick and collagen rich connective tissue.
