Osseous (bone) surgery may be recommended when supportive bone around the root of the tooth is diseased and partially destroyed. This procedure is used to smooth shallow craters in the bone due to mild or moderate bone loss. First, flap surgery is performed to reach the damaged bone, where plague and tartar are removed from the infected pocket. Then the bone is smoothed and reshaped, reducing spaces where bacteria can grow.
Finally, the gum is closed and sutured over the reshaped bone at or below the original gumline. After healing, stitches dissolve or are removed.
