| Acute ulcerative gingivitis, also known as Vincent's disease or trench mouth, is due to a bacterial infection of the gums. |
| Gum bleeding is usually caused by gingivitis which is inflammation of the gum margin around the necks of the teeth. |
| The most common cause of gingivitis is the accumulation of dental plaque on exposed tooth surfaces. |
| The skin and mucous membranes should be inspected for cyanosis, pallor, ecchymoses, telangiectasia, gingivitis, or evidence of bleeding from the oral or nasal mucosa. |
| Neither debris nor calculus is a measure of disease, but they can increase the risk for the development of gingivitis. |
| Acute ulcerative gingivitis results from severe infection of the gums and is extremely painful. |
