Gum disease is typically the result of inadequate or ineffective oral hygiene practices that lead to the accumulation of dental plaque, which is sticky film that is colonized by oral bacteria. The harmful bacteria and the products they produce provoke a defensive, inflammatory response in the gums. When this inflammation is not resolved, tissue damage ensues and spaces between the gums and teeth that are known as periodontal pockets develop. As the periodontal pockets deepen, the bacteria become more difficult to remove and the gaps between the surface of the teeth and gums get larger. When pocket depth increases to the point of being beyond the reach of deep cleanings and other conservative methods of care (5mm or more), gum surgery to clean and treat the damage to gums and underlying bone is recommended.
