Gingivitis is a much milder type of gum disease that without proper treatment or professional cleaning will eventually develop into periodontitis as it worsens. Some signs or symptoms that will indicate that you are suffering from periodontitis include: - Gum sensitivity or tenderness when touched - Gums that are visibly swollen, bright or dark red in color, and bleed easily - Presence of blood from the gums whenever brushing or flossing the teeth - Persistent bad breath - Pus that develops in between the teeth and gums - Experiencing pain or sensitivity when chewing - Teeth that are loose or falling out - Receding Gumlines - Changes in bite, the way that your teeth fit together when biting If you previously suffered from gingivitis but have not been able to receive professional interventions to properly deep clean the teeth, and the symptoms have only worsened, you should visit a dental professional as soon as possible to treat the gum disease and to prevent losing any teeth if possible.
