In brief: Gums that bleed. Gingivitis is the beginning stages, and by definition, your gums are inflamed, and you might see them bleed when you brush and floss. If this is left untreated, then the infection moves deeper into the jaw, and it progresses to the more severe, periodontal disease.
The symptoms of PTSD can start immediately or after a delay of weeks or months, but usually within 6 months of the traumatic event. Many people feel grief-stricken, depressed, anxious, guilty and angry after a traumatic experience.
PTSD is diagnosed if symptoms last more than one month. Symptoms may appear with three months of the trauma, but can also start months or years later. PTSD may be accompanied by depression, substance abuse, and anxiety disorders. Assessments are made by a physician, pediatrician or clinician. The acronym DREAMS is used as a diagnostic in PTSD.
