Gingivitis. Otherwise known as gum inflammation, tends to happen around the base of someone’s teeth. Their gums might bleed a bit as you brush or floss, which they may see as you go about your normal oral hygiene routine. Other signs of gingivities include bad breath and redness of the gums. Slight gum disease. This may happen if patients don’t take care of their bleeding gums. Bacteria in teeth may start to get into the jaw where adult teeth stay anchored and strong. In addition to more bleeding, a dentist may notice some bone loss as he or she gently examines the gums. A dentist may recommend a deep cleaning at this stage and possibly antibiotics.  Moderate gum disease. At this stage, a dentist may notice other difficulties start to set in. Treatment options for moderate gum disease include trying to stop the spread of the bacteria further into the bones. There is also a possibility that the infection may start to spread to the rest of someone’s body. A doctor may perform a deep cleaning while prescribing antibiotics to try to stop the bacteria from advancing. Advanced gum disease. Adult teeth are very stong and deeply set into the jawbone. For adult patients with advanced gum disease, they may see a loose tooth or several loose teeth, have pain while chewing, and notice very bad breath. A dentist may recommend oral surgery before the tooth loss increases. Without further treatment to stop the advance of gum disease, patients may also see spacing gaps between teeth and receding gums.
