Often referred to as “Periodontitis”, gum disease is a common type of oral infection that affects the gum and bone tissues responsible for supporting your teeth. It initially starts out as gum inflammation, a.k.a. Gingivitis, which will progress to Periodontitis if not addressed in a timely manner.
The word periodontal refers to “perio-” (around) the “-dont”(tooth). That is, the infection isn’t inside of the tooth itself, but rather encircles it by causing the damage to bone and gingival (gum) tissues immediately adjacent to it.
