It is a procedure used by the dentist to access the gum infection that is not accessible from the outside. It consists of carefully opening the gum on the outside and inside, to reach the bone and be able to scratch and remove the deep infection. Stitches will always have to be placed to adequately close the gum. Surgery is a very effective procedure to eliminate pockets of infection and facilitate the control of the health of the gums over time and ensure that you have more resistant teeth.
